Machine learning (ML) is a subfield of Artificial Intelligence (AI), focused on creating algorithms and statistical models that enable computers to learn from, make predictions or decisions based on data without being explicitly programmed for these tasks. The goal of machine learning is to develop systems which will adapt as more data comes in over time - increasing performance while becoming smarter over time.

There are various approaches to machine learning:

Supervised Learning: In supervised learning, an algorithm is trained on labeled data sets with input and corresponding output labels provided, so as to learn a mapping between inputs and outputs so it can make predictions on untried, unseen data sets. The goal is for the algorithm to make accurate predictions over new, unseen inputs as it develops its predictions on them.

Unsupervised Learning: Unsupervised learning entails training algorithms on unlabeled data without providing any explicit direction; instead, the system attempts to detect patterns or structure within it without guidance from outside sources. Clustering and dimensionality reduction are common unsupervised learning tasks.

Semi-Supervised Learning: Semi-supervised learning combines elements of both supervised and unsupervised learning techniques; here, an algorithm is trained on both labeled and unlabeled data sets with limited labeled data available as inputs.

Reinforcement Learning: Reinforcement learning involves an agent making decisions in an environment to meet a goal, receiving rewards or penalties to make these decisions, and learning optimal strategies through trial-and-error.

Industry Overview

Machine learning has many applications across various domains, from computer vision and natural language processing, speech recognition and recommendation systems to medical diagnosis and financial forecasting.

Notably, machine learning requires extensive data for training purposes; both quality and quantity of data play an integral part in its effectiveness. Furthermore, creating machine learning models includes preprocessing data, feature engineering models selection process model selection hyperparameter tuning evaluation to ensure maximum performance of models created.
