The discipline of machine learning employs various approaches to teach computers to accomplish tasks where no fully satisfactory algorithm is available. In practice, it can turn out to be more effective to help the machine develop its own algorithm, rather than having human programmers specify every needed step. For more advanced tasks, it can be challenging for a human to manually create the needed algorithms.

For simple tasks assigned to computers, it is possible to program algorithms telling the machine how to execute all steps required to solve the problem at hand on the computer's part, no learning is needed. It involves computers learning from data provided so that they carry out certain tasks. Machine learning programs can perform tasks without being explicitly programmed to do so. They can be nuanced, such as 'X% of families have geographically separate species with color variants, so there is a Y% chance that undiscovered black swans exist'. These inferences can be obvious, such as 'since the sun rose every morning for the last 10,000 days, it will probably rise tomorrow morning as well'. Learning algorithms work on the basis that strategies, algorithms, and inferences that worked well in the past are likely to continue working well in the future.

2 History and relationships to other fields.

In its application across business problems, machine learning is also referred to as predictive analytics. Some implementations of machine learning use data and neural networks in a way that mimics the working of a biological brain. Data mining is a related field of study, focusing on exploratory data analysis through unsupervised learning. The study of mathematical optimization delivers methods, theory and application domains to the field of machine learning. Р”Р„ subset of machine learning is closely related to computational statistics, which focuses on making predictions using computers but not all machine learning is statistical learning. Machine learning algorithms are used in a wide variety of applications, such as in medicine, email filtering, speech recognition, and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks. Machine learning algorithms build a model based on sample data, known as ' training data', in order to make predictions or decisions without being explicitly programmed to do so.

It is seen as a part of artificial intelligence. Machine learning ( ML) is the study of computer algorithms that can improve automatically through experience and by the use of data.
