This article discusses the fundamentals of AI and offers a step-by-step guide to building an AI app.

What is artificial intelligence?

Artificial intelligence is a field of computer science that focuses on solving cognitive programs associated with human intelligence, such as pattern recognition, problem-solving and learning. AI refers to the use of advanced technology, such as robotics, in futuristic scenarios. There have been many definitions surfaced of artificial intelligence, but John McCarthy provides the following definition in his 2004 paper – ” It is the science and engineering of making intelligent machines, especially intelligent computer programs. It relates to the similar task of using computers to understand human intelligence, but AI does not have to confine itself to biologically observable methods.”

Artificial intelligence, in its most basic form, is a field that combines computer science with robust datasets to facilitate problem-solving. Artificial intelligence also includes sub-fields like machine learning and deep learning, which are often mentioned together. The algorithms of these technologies are used to build expert systems that can make predictions and classifications based on input data. AI encompasses many disciplines, including computer science, data analytics, statistics, hardware, software engineering, neuroscience, psychology, and philosophy.

What are the components of AI?

components of AI


Computer programs learn differently from humans. Computer learning can be further divided into many forms where learning for AI is one of the most important components. It includes solving of problems using the trial-and-error method. The program also keeps track of the positive moves and saves them in its database for the next time it faces the same problem. Learning in AI is memorizing individual items, such as vocabulary and solutions to problems. It’s also called rote learning. This learning method can later be applied using the generalization technique.


Until five decades ago, the art of reasoning was a skill limited to humans. The ability to distinguish makes reasoning an essential component of artificial intelligence. This ability allows the platform to draw inferences compatible with the given situation. These inferences can be classified as either deductive or inductive. There is a great success rate using deductive inferences via programming computers. Inferential cases provide guarantees that a problem can be solved. For example, the accident is an inductive case; however, always due to instrument failure.

Reasoning involves drawing inferences relevant to the current situation.


AI’s problem-solving ability is basic, including data where the solution must find an unknown value. AI witnesses many problems being solved on the platform. These methods are essential components of artificial intelligence that divide queries into general and special purposes. A special-purpose method is a solution that is tailored to solve a particular problem which is often done by leveraging some of the features found in the case in which the problem was embedded. A general-purpose approach can solve many different problems. At the same time, AI’s problem-solving component allows programs to reduce differences step-by-step between goals and current states.


Artificial intelligence’s ‘perception’ component allows the element to scan any environment using different sense organs. The internal processes allow the perceiver the ability to examine other scenes and determine their relationship. This analysis can be complicated and similar objects might appear differently at different times depending on how the angle is viewed.

Perception is a component of artificial intelligence that can propel self-driving cars at moderate speeds. FREEDY is one of the first robots to use perception to identify different objects and assemble artifacts.


Language can be described as a collection of system signs that are consistent with each other. Language understanding is a widely used component of artificial intelligence that uses distinct types of language to understand natural meanings, such as overstatements. Human English is one of the most important characteristics of languages allowing us to distinguish between objects. AI is designed in such a way that it can understand English, the most common human language. The platform makes it possible for computers to understand different computer programs that are executed on them easily.

This technique allows computers to learn without being explicitly programmed and used in real-life use cases. It is fundamentally the science that allows machines to interpret, execute, and analyze data to solve real-world problems. Programmers use complex mathematical knowledge to design machine-learning algorithms written in a machine-readable language to create a complete ML system. Besides, ML allows us to decode, categorize and estimate data from a dataset.

It has provided self-driving cars, image and speech recognition, demand forecasting models, useful search, and many other applications over the years. It focuses on applications that can adapt to experience and improve their decision-making or predictive accuracy over time.

Data professionals also choose types of machine learning algorithms as described below depending on data availability.

  • Supervised learning: Data experts feed labeled training data into algorithms and assign variables to the algorithms to access and find correlations. Both the input and output of the algorithm are particularized.
  • Unsupervised learning: These types of learning use algorithms that train with unlabelled data. An algorithm analyzes datasets to draw meaningful connections or inferences. Cluster analysis, for example, uses exploratory data analysis to find hidden or grouping patterns in data.
  • Reinforcement learning: Reinforcement learning is used to teach a computer to follow a multi-step process with clearly defined rules. Programmers create an algorithm that will perform a task. They then give the algorithm positive or negative signals to execute the task. Sometimes the algorithm decides for itself what actions to take.

Neural network

The neural network combines cognitive science with machines to complete tasks. It is a branch of artificial intelligence that uses neurology, a part of biology that deals with the nerve and nervous system. The neural network is a way to simulate the human brain, where there are infinite numbers of neurons.

A neural network, in simple terms, is a collection of algorithms used to discover the elemental relationships among the data sets. It mimics the human brain’s operating process. A neural network is a system of neurons that are either artificial or original in nature. A neuron is a mathematical function in a neural network whose job is to collect and classify information according to a specific structure. The network strongly implements statistical techniques such as regression analysis to complete tasks. They are used extensively for everything from market research to forecasting, fraud detection, risk analysis, and stock exchange prediction.


This is an emerging field of artificial intelligence and a fascinating field of research and innovation that focuses mainly on the design and construction of robots.

AI researchers are also working on robots that use machine learning to enable interaction at the social level.

Expert systems

The first successful AI software model was the expert system created in the 1970s and became more popular in the 1980s.

An expert system is a computer system that imitates human experts in decision-making. This is done by using its knowledge base to derive knowledge and then applying reasoning and insights rules to the terms of user queries. Expert systems’ effectiveness is dependent on the knowledge of the expert. The more information the system has, the greater its efficiency will be. The expert system offers suggestions for spelling and grammatical mistakes in the Google search engine. The system can be used to solve complex problems by reasoning with proficiency. This is especially true when using “if-then” rules rather than traditional agenda to code. Expert systems are highly responsive, reliable, understandable, and efficient in execution.

Fuzzy logic

Fuzzy logic is a type of mathematical logic that deals with approximate reasoning rather than fixed and exact reasoning. It simulates the ambiguity and uncertainty that frequently exists in real-world situations. Fuzzy logic is used to process and analyze data from various sources in order to make decisions.

Natural language processing (NLP)

In layman’s terms, NLP is a part of computer science and AI that allows communication between humans and computers using natural languages. It allows computers to understand and read data mimicking natural human language. NLP refers to a method of searching, analyzing and understanding text data. Programmers use the NLP library to teach computers how useful the information is from text data. NLP is commonly used to detect spam. At the same time, computer algorithms can look at the subject or text of an email to determine if it is junk or not.

How does AI work?

Step 1: Problem identification and setting goals

First, identify the problem to be solved before you build an AI app. Consider the functions and processes of the app in which you want to use the AI technology stack. What result should you expect from it? How will you benefit? Once you have identified the problem and the idea, you can start to create product requirements. Based on the requirement analysis, developers can understand the purpose of creating products and find technologies and tools to help them.

You will also need to do the following during the planning stage:

  • Decide the composition of the technical and non-technical team- from project managers and business analysts to data engineers and backend programmers.
  • Discuss your work schedule with professionals.
  • Start exploring the data needed to build an AI/ML model.

To ensure the success of your AI application, it’s crucial to start by establishing clear objectives. As motivational speaker Tony Robbins eloquently puts it, “Setting goals is the first step in turning the invisible into the visible.” These goals will serve as your development’s guiding star, keeping the process focused and aligned with your vision, ensuring every stakeholder is on the same page.

Indeed, the key to every successful AI application is the clarity of its goals from the outset. Begin by pinpointing the specific problem your app intends to solve for its users. For instance, consider Grammarly, which has a well-defined aim to enhance user writing through real-time grammar and style corrections — a goal it proficiently fulfills.

Once your primary goal is set, it’s essential to establish Key Performance Indicators (KPIs) that adhere to the SMART (Specific, Measurable, Achievable, Relevant, Time-framed) framework to measure your app’s success. Some of the AI-specific KPIs might include:

  • Model accuracy
  • Model precision
  • Model recall
  • F1-score
  • Model fairness

These metrics are invaluable for evaluating the efficacy of your AI model. Additionally, setting clear development and deployment milestones is crucial, and leveraging an agile development methodology like Scrum can facilitate this process.

Before embarking on the development, assess the resources at your disposal. AI models can be resource-intensive, requiring substantial infrastructure to support both training and maintenance phases. Ensure your infrastructure is robust enough to handle the demands.

In conclusion, the goals you set at the beginning of your AI app’s development journey will steer you throughout the process, emphasizing the importance of getting them right from the start.

Step 2: Preparation of data

Data collection and preparation form the cornerstone of AI application development. The success of even the most sophisticated AI models hinges on the quality of the data they are trained with. It is essential to prioritize data quality over quantity to avoid the substantial costs associated with poor data. In fact, a Gartner survey highlighted that organizations estimate losses averaging $15 million annually due to bad data quality.

To mitigate such losses, ensuring your data is thoroughly cleaned and formatted is crucial. The selection of the right datasets for training your AI model is the first step. For those working on natural language processing models, Common Crawl offers a robust, freely available repository of web crawl data, which was used for 82% of the raw tokens in OpenAI’s GPT-3 model.

Platforms like Kaggle and AWS Data Exchange also provide a wealth of specific datasets that can be leveraged at no cost. Once you have chosen your datasets, the next steps involve thorough data preparation through cleaning, preprocessing, and wrangling.

  • Data cleaning eliminates inaccuracies such as duplicate entries using tools like OpenRefine and Tibco Clarity.
  • Preprocessing extends beyond cleaning to include transformation, integration, normalization, smoothing, and reduction—each step enhancing the quality of your data.
  • Data wrangling then transforms this preprocessed data into a format suitable for training AI models. After these stages, your data is ready to be used for model training or fine-tuning.

Remember, effective data collection and preparation are not just preliminary steps but are critical to building a robust AI application. It’s not just about doing it, but doing it right.

Step 3: Choosing the right tools and frameworks

The success of your AI application hinges on selecting the appropriate tools and frameworks for building and training your models. This choice should align with your specific business needs and integrate seamlessly with your existing infrastructure. Opting for the right tools not only accelerates development but also enhances the performance of your AI models.

Step 4: Designing and training/fine-tuning AI model

The design phase begins by defining the structure of your model based on the problem it aims to solve. Here’s how to proceed:

Choose the training approach

  • Supervised learning: Best for scenarios where the outcomes are known and the data is labeled. It’s extensively used in applications requiring high accuracy such as facial recognition or weather forecasting.
  • Unsupervised learning: This approach is suitable for discovering hidden patterns or intrinsic structures within data, like in clustering or anomaly detection tasks.
  • Reinforcement learning: Effective in decision-making processes, the model learns to behave in an environment by performing certain actions and receiving rewards. This method is particularly useful in fields such as robotics and gaming.

Select the right model architecture

  • Convolutional Neural Networks (CNNs): Primarily used for image and video recognition, CNNs are also effective in any type of pattern recognition model due to their ability to accurately identify features regardless of the noise and distortions in the image.
  • Recurrent Neural Networks (RNNs): Suitable for handling sequential data such as time series analysis or natural language processing, where the sequence of data points is crucial.
  • Generative Adversarial Networks (GANs): Ideal for generating new data that mimics the input data, commonly used in creating realistic images, video enhancement, and art generation.

Preparing for training

  • Data Splitting: Segment the data into three parts: training, validation, and testing. The typical split is 70% for training to allow the model to learn as much as possible, 15% for validation to tune the parameters, and 15% for testing to evaluate the model’s performance.
  • Feature engineering: This involves selecting, modifying, or creating new features from the raw data to increase the model’s ability to discern patterns.

Training your AI model

  • Feeding data: Train your model using the training data. This involves multiple iterations where the model makes predictions and adjustments to improve.
  • Hyperparameter tuning: Adjust the model settings (hyperparameters) during the validation phase to find the optimal configuration for the best performance.
  • Cross-validation: Use cross-validation techniques during training to ensure the model’s effectiveness across different subsets of the dataset.

Evaluating and integrating the model

  • Testing: After training, test the model using the unseen test data. This is critical to ensure that the model performs well in real-world scenarios.
  • KPI measurement: Evaluate the model’s performance using predetermined KPIs such as accuracy, precision, recall, F1 score, and ROC-AUC depending on the application’s needs.

Advanced approaches in Generative AI

For generative AI applications, you may employ advanced techniques such as embeddings, retrieval-augmented generation (RAG), and fine-tuning are instrumental in enhancing the capabilities and performance of AI models. Here’s a closer look at how these approaches are implemented:

Embeddings in Generative AI

Embeddings are a fundamental component in many AI applications, especially in the context of Generative AI. They transform high-dimensional data (like text or images) into a lower-dimensional space while preserving semantic relationships. This process involves representing data points (such as words or phrases) as vectors in a continuous vector space where semantically similar items are closer together. This technique is crucial for tasks like text generation, where understanding and maintaining context is essential.

Retrieval-Augmented Generation (RAG)

RAG is a sophisticated approach that combines the power of generative models with information retrieval systems. This hybrid method enhances the model’s ability to generate contextually relevant and accurate responses by:

  1. Retrieving information: When a query is received, the model uses an information retrieval system to fetch relevant content from a large dataset or knowledge base.
  2. Augmenting generation: The retrieved information is then fed into a generative model, which integrates this context to produce a coherent and contextually enriched response.

This approach is particularly useful in applications like chatbots or question-answering systems, where providing precise and informed responses is critical.


Fine-tuning is a process where a pre-trained model is further trained (or “fine-tuned”) on a new, typically smaller, dataset that is specific to a particular task or domain. This method leverages the general capabilities of the model, learned from a large-scale dataset, and adapts it to the nuances of a specialized task. Steps involved in fine-tuning include:

  • Data preparation: The specific dataset is prepared, often requiring preprocessing steps such as normalization, tokenization, or labeling.
  • Model adjustment: The pre-trained model’s parameters are slightly adjusted based on the new data, enabling it to better perform the new task.
  • Training: The model is trained on the new data, but with a focus on refining rather than learning from scratch, typically requiring fewer computational resources and less time than training a model from the ground up.

Fine-tuning enhances the model’s performance on specialized tasks and can significantly increase its accuracy and relevance to the specific needs of an application.

By implementing these advanced techniques, developers can create more powerful, adaptable, and efficient Generative AI models, tailored to the unique demands of their applications.

Step 5: Model integration into the app

Integrating your AI model into your app represents a pivotal moment in the development process—it’s essentially the deciding factor for the success of your AI application. This critical phase determines whether your AI capabilities will truly enhance the user experience or fall short of expectations.

The first decision you’ll face is determining whether to embed your AI model within the app’s front-end or back-end. Typically, AI models are integrated into the front-end to interact directly with users. However, certain models, such as those for speech recognition, might perform better when integrated into the back-end to enhance accuracy and processing power.

Next, consider where your AI model will process data: on the cloud or directly on the device. On-device processing, or edge AI, is particularly beneficial for AI-powered Internet of Things (IoT) applications, offering responsiveness and enhanced privacy. For most applications, though, cloud-based processing is usually more practical due to its scalability and power.

Integrating an AI model doesn’t have to be an arduous process. There’s no need to start from scratch if there are existing AI APIs available that can meet your needs. For instance, Google Cloud Vision API provides robust AI image analysis capabilities that can be easily incorporated into your app, saving valuable development time.

Moreover, it’s essential to establish a feedback loop within your app. This feature allows users to provide feedback and rate the performance of your AI model, offering crucial data that can be used to refine and improve the model continuously.

Transparency about your app’s AI functionalities is also key. Clearly communicating how the AI works and its benefits helps in building trust with your users. Despite the complexity of the underlying technology, interactions with the AI model should remain straightforward and intuitive for users.

Ultimately, developing an AI app is not just about integrating technology—it’s about ensuring that this technology significantly enhances the overall user experience of your app.

Step 6: Model testing and iteration

The development of your AI app isn’t a one-time event; it marks the beginning of an ongoing process of enhancement and refinement. It’s essential to view every AI model as a continual work in progress, necessitating persistent testing and iteration to foster growth and improvement.

AI models are inherently imperfect at inception. They must learn from experience and adapt over time. Moreover, regular retraining with updated datasets is crucial to prevent ‘model drift,’ a common issue where the model’s performance degrades due to changes in underlying data patterns. This continuous updating keeps the model accurate and relevant throughout its lifecycle.

But what methods should you employ to effectively test your AI app? There are three primary types of testing to focus on:

  1. Unit testing: This stage tests the smallest parts of your app individually. For instance, if your app includes an AI chatbot, you might test whether its greeting function activates properly. Automating these tests ensures consistent checks without burdening your QA team.
  2. Integration testing: This phase evaluates how well the various components of your app work together. For an AI-driven application, it’s crucial to see how the AI model interacts with other parts of the app under conditions that mimic real-world usage. This helps ensure the app operates smoothly as a cohesive unit.
  3. User Acceptance Testing (UAT): The final stage of testing, UAT ensures that your app meets the practical needs and expectations of its end-users. It’s beneficial to involve a diverse group of users in this testing phase to gather a broad spectrum of feedback, which can provide invaluable insights into user behavior and preferences.

Beyond these core testing types, your QA engineers will likely engage in numerous other testing procedures throughout the development process. However, unit, integration, and user acceptance testing are fundamental to ensuring the success of your AI application.

Incorporating a feedback loop is also vital. It allows you to capture and integrate user feedback continually, thereby enabling iterative improvements that align closely with user needs and enhance app performance.

By adopting this rigorous testing framework and maintaining an open channel for user feedback, you ensure that your AI app remains effective and relevant far into the future.

Navigating privacy, security, and compliance challenges is crucial in the development and deployment of AI technologies. As AI systems become more integral to business operations and consumer products, ensuring that these systems are secure, respect user privacy, and comply with relevant regulations is not just a technical necessity but also a legal and ethical imperative. Here’s a detailed look at each of these critical areas:


Privacy concerns in AI revolve around the vast amounts of data AI systems require, which often include sensitive personal information. Protecting this data is paramount to maintaining user trust and ensuring compliance with privacy laws such as the General Data Protection Regulation (GDPR) in Europe, the California Consumer Privacy Act (CCPA), and other global privacy standards.

Strategies for enhancing privacy in AI

  • Data anonymization: Transforming personal data in such a way that the individual is not or no longer identifiable, which minimizes the privacy risks associated with data processing.
  • Differential privacy: Implementing systems that allow data analysis without giving up the privacy of the data subjects, adding random noise to the data or queries to protect individual privacy.
  • Secure multi-party computation: Allowing multiple parties to jointly analyze their inputs without revealing them to each other, enhancing privacy in collaborative environments.


AI systems are as vulnerable to cyber threats as any other technology system. However, the stakes can be higher due to their decision-making capabilities. A breach in AI security could lead to unauthorized access to AI data, manipulation of AI models (model poisoning), or exploitation of AI systems (adversarial attacks).

Strategies for enhancing security in AI

  • Robust authentication and access controls: Ensuring that only authorized individuals can access AI systems and data.
  • Regular security audits: Conducting thorough audits to identify and mitigate vulnerabilities in AI applications.
  • Adversarial training: Including potential attack vectors during the training phase of AI model development to make them more robust against malicious inputs.


AI developers must ensure that their applications comply with a myriad of regulations that govern data protection, ethical AI use, and sector-specific requirements. Compliance is not static, so understanding ongoing legislative developments and adapting AI practices accordingly is essential.

Strategies for ensuring compliance in AI

  • Regular compliance reviews: Keeping up-to-date with the latest AI governance frameworks and regulatory changes and assessing AI systems regularly to ensure compliance.
  • Ethical AI frameworks: Developing and following ethical guidelines for AI use that conform to legal standards and public expectations.
