data science

Mainly, Agent with a learning function, which generally, takes in data that encodes its experience, and modify its behaviour according to that data.(which makes data science its sister discipline)

• regression
• statistical machine learning
• probabilistic machine learning
• dynamic machine learning

• dynamic machine learning
• reinforcement learning
• discrete feature encoding

In data science and machine learning, a feature is a measurable property of a phenomenon.

In the raw data form, it normally refers to a single column in the data set such as follows:

name	favorite color	height	net worth
james	red	1.7	5000
josh	blue	1.8	4000

In this dataset, favorite color is a feature, and height is another one. They both describes some measureable property of people like james and josh

favorite color would be refer to as a discrete-valued feature, while height a continuous feature, and the whole row

james

red

1.7

5000

a feature vector
