Summary

Theory

Machine learningLearning means changes in a system that have adaptive character, so a system may realize the same or

similar task in a more efficient way with every next attempt. - Herbert Simon (1983)

Learning is a constructing and changing the representation of experienced facts. - Ryszard Michalski (1986)

Learning system uses external empirical data in order to create and update foundations for improved activity in the future when based on similar data. - Donald Michie (1991)

New paradigm

Traditional programming Machine learning

Why?

Exponential growth of data (social networks, IoT – Internet of Things) - 44 tryllions of GB will be generated till 2020

Cheap data storage

Big computing power of personal computers

Real influence on profits

World (and especially human behavior) is based on patterns

In 2013 roku 22% of data was valuable for analysis, but only 5% from that was analyzed. Till 2020 35% of data will be valuable for analysis

Currently around 7% of devices transmit data – they produce 2% of world’s data. Till 2020 they will be producing 10%.
