Analyzing the data Flashcards
Brief Introduction to Machine Learning
Machine learning enabled not only to deal with large volume of data, but it brought a tremendous value to business and consumers by extracting valuable insights and hidden patterns.
Three main approach in ML
Supervised: we know what the outputs are of each data points;
Unsupervised: we don’t know the outputs. For example we have millions of samples of blood work. We don’t know what are they but the cell numbers.
Reinforcement learning: it consists of devising an algorithm that learns how to behave based on a system of rewards.
Techniques for social media analysis
Machine Learning
Text Mining: retrieve non trivial information from textual data
Natural Language processing: more extensive and aim at finding the meaning of the text
Graph Mining: social network represented by graph structures.
