Data Science heavily relies on artificial intelligence (AI) and its subsets, machine learning (ML) and deep learning (DL). Pre-processing, analysis, visualisation, and prediction are all steps in the overall process known as “data science.” Let’s take a closer look at AI and its subgroups.

Building intelligent machines that can carry out tasks that traditionally require human intelligence is the goal of the field of computer science known as artificial intelligence (AI). The three categories of AI are listed below.
Narrow Artificial Intelligence (ANI)
AGI and ASIS are two terms for artificial super intelligence (ASI).
Narrow AI, sometimes known as “weak AI,” excels in performing a single task in a specific fashion. For instance, a robotic coffee maker that makes coffee by following a predetermined set of steps. AGI, often known as “Strong AI,” performs a variety of jobs that require thinking and reasoning similarly to humans. Examples of NLP applications include Google Assist, Alexa, and chatbots (NPL). The most developed form, called Artificial Super Intelligence (ASI), is superior to human capacity. It is capable of carrying out creative tasks like making art, decisions, and emotional connections.
Let’s now examine machine learning (ML). It is a branch of AI that entails the modelling of algorithms that aid in the generation of predictions based on the identification of intricate data sets and patterns. The main goal of machine learning is to provide computers the ability to learn from the data presented, gain understanding, and, using the knowledge gained, make predictions on data that has not yet been thoroughly examined. There are numerous machine learning techniques.
supervised education (Weak AI – Task driven)
Semi-supervised learning and unsupervised learning with strong artificial intelligence (Strong AI -cost effective)
enhanced computer learning. (Powerful AI – learn from errors)
In order to comprehend behaviour and create future forecasts, supervised machine learning makes use of historical data. In this case, the system consists of a specific dataset. It is marked with the input and output parameters. And as fresh data is added, the ML algorithm analyses it and, using the predetermined parameters, produces an exact result. You can conduct classification or regression tasks using supervised learning. Image classification, face recognition, email spam classification, identity fraud detection, etc. are examples of classification tasks, and weather forecasting, population growth projection, etc. are examples of regression tasks.
The parameters used in unsupervised machine learning are neither categorised or labelled. It concentrates on revealing hidden structures from unlabeled data to assist systems in correctly inferring a function. They employ strategies like dimensionality reduction or grouping. Clustering is putting related metrics-based data items in groups. It is data-driven, and some instances of clustering include Netflix user movie recommendations, consumer segmentation, purchasing patterns, etc. Examples of dimensionality reduction include big data visualisation and feature elicitation.
To increase learning accuracy, semi-supervised machine learning uses both labelled and unlabeled input. When labelling data turns out to be expensive, semi-supervised learning may be a viable alternative.
Comparing reinforcement learning to supervised and unsupervised learning reveals certain differences. It may be characterised as a process of trial and error that eventually produces results. It is accomplished using the iterative improvement cycle principle (to learn by past mistakes). Agents have also been taught autonomous driving via reinforcement learning in virtual environments. Algorithms for reinforcement learning include Q-learning.
Let’s move on to Deep Learning (DL), a branch of machine learning where you create algorithms with layered architecture. To gradually extract higher level features from the raw input, DL employs many layers. In image processing, for instance, lower layers might recognise borders, while higher layers might identify things that are important to people, like numbers, letters, or faces. Deep Learning (DL) is a broad term for an artificial neural network, and these method sets are quite accurate for issues like sound and image identification, natural language processing, etc.
In conclusion, AI, which includes machine learning, is covered by data science. However, deep learning is a sub-technology that is itself covered by machine learning. Thanks to AI, which can now solve more complex issues (such identifying cancer more accurately than oncologists) than people can.
