(Python Example for Beginners)
Write a Pandas program to compute difference of differences between consecutive numbers of a given series.
Sample Solution :
Python Code :
import pandas as pd series1 = pd.Series([1, 3, 5, 8, 10, 11, 15]) print("Original Series:") print(series1) print("nDifference of differences between consecutive numbers of the said series:") print(series1.diff().tolist()) print(series1.diff().diff().tolist())
Original Series: 0 1 1 3 2 5 3 8 4 10 5 11 6 15 dtype: int64 Difference of differences between consecutive numbers of the said series: [nan, 2.0, 2.0, 3.0, 2.0, 1.0, 4.0] [nan, nan, 0.0, 1.0, -1.0, -1.0, 3.0]

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
