Data science vs Machine Learning and Artificial Intelligence

Overview

Data Science incorporates extracting insights from large and complex data sets using a variety of techniques like statistical analysis, data visualisation, and predictive modelling. It involves the absolute data lifecycle, including collection, exploration, analysis, and interpretation of data. Scientists apply mathematical and statistical approaches to uncover patterns and correlations within the data. They also use programming languages like Python to manipulate and analyse data. Machine Learning is a subdivision of Artificial Intelligence that permits computers to grasp the data and make forecast decisions without being explicitly programmed. It possesses the construction of mathematical models that automatically learn and refine from experience. Machine Learning algorithms are purposefully designed to identify patterns and make predictions based on data inputs.

These algorithms can be classified into supervised learning (where models are trained on labelled data), unsupervised learning (where models find patterns in unlabeled data), and reinforcement learning (where models learn through interaction with an environment). Artificial Intelligence (AI) refers to the inducement of human intelligence in machines that are programmed to imitate cognitive functions like learning, problem-solving, reasoning, and decision-making. AI encompasses a broader scope beyond just data analysis and prediction. It involves the development of intelligent systems that can perceive and interpret the world, understand natural language, perform complex tasks, and adapt to changing circumstances. Machine Learning is a key component of AI, as it provides the algorithms and techniques for training intelligent systems to learn from data.
