(Python Example for Beginners)
Write a NumPy program to compute the condition number of a given matrix.
From Wikipedia: In the field of numerical analysis, the condition number of a function with respect to an argument measures how much the output value of the function can change for a small change in the input argument. This is used to measure how sensitive a function is to changes or errors in the input, and how much error in the output results from an error in the input.
Python Code :
import numpy as np m = np.array([[1,2],[3,4]]) print("Original matrix:") print(m) result = np.linalg.cond(m) print("Condition number of the said matrix:") print(result)
Original matrix: [[1 2] [3 4]] Condition number of the said matrix: 14.9330343737

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.
