Feature engineering involves applying business knowledge, mathematics and statistics to transform data into a form that machine learning models can use . Algorithms depend on data to drive machine learning algorithms. A user who understands historical data can detect the pattern and then develop a hypothesis.

The feature engineering process is:
Read moreWhat are the 3 components of time series?
An observed time series can be decomposed into three components: the trend (long term direction), the seasonal (systematic, calendar related movements) and the irregular (unsystematic, short term fluctuations) .
Read moreWhat are the 4 components of time series in statistics?
Let Y t be a time series that can be decomposed with the help of these four components: Secular trend T . Seasonal variations S. Cyclical fluctuations C.
Read moreWhich package is used for data analysis in Python?
Pandas. Pandas (Python data analysis) is a must in the data science life cycle. It is the most popular and widely used Python library for data science, along with NumPy in matplotlib.
