The primary role of a training dataset is to allow the model to learn the underlying patterns and relationships
            between the features and the labels. The size of the training dataset can significantly impact the performance
            of the model. Generally, a larger training dataset can allow the model to learn more robust patterns, but an
            excessively large dataset can also lead to diminishing returns.

            Testing Dataset
            A Testing Dataset is a subset of data used to evaluate the performance and generalisation ability of a trained
            machine learning model. It is distinct from the training dataset and is crucial for understanding how well the
            model can perform on unseen data. The primary purpose of the testing dataset is to provide an unbiased
            evaluation of the model’s performance after it has been trained. The testing dataset also plays an essential role
            in ensuring that the model can be effectively deployed in real-world applications.
            AI MODELLING

            AI Modelling refers to the process of creating algorithms and models that allow machines to mimic human
            cognition and perform tasks involving understanding, reasoning, and learning from data. This includes various
            techniques from machine learning, deep learning, natural language processing, and other areas of Artificial
            Intelligence.
            The goal of AI Modelling is to develop systems that can perform tasks intelligently and adaptively, often exceeding
            the capabilities of traditional programming techniques.

            Types of AI Models

            In general, AI Modelling techniques can be broadly classified into two approaches:
                                                                                            Supervised
                                                                                             Learning


                                                                       Machine             Unsupervised
                                                                       Learning              Learning


                                                                                           Reinforcement
                                               Learning Based                                Learning

                             AI Models                                                    Artificial Neural
                                                 Rule Based             Deep                 Networks

                                                                       Learning
                                                                                         Convolution Neural
                                                                                             Networks

            Rule Based Approach

            The Rule based approach to AI modelling is a simple and easy approach because it is directly based on simple
            “if – then” rules. This approach is used to build an AI system that works on the basis of a predefined hierarchy of
            rules that govern how to transform user input into desired course of action or automated actions. The two major
            components of rule-based AI models are “a set of rules” and “a set of facts”.
            Examples of Rule-based AI Models

            Example: To develop a rule-based chatbot for an e-commerce website that helps customers with common
            inquiries about their orders and other issues.
