(Python Example for Beginners)
Write a NumPy program to repeat all the elements three times of a given array of string.
import numpy as np x1 = np.array(['Python', 'PHP', 'Java', 'C++'], dtype=np.str) print("Original Array:") print(x1) new_array = np.char.multiply(x1, 3) print("New array:") print(new_array)
(['Python', 'PHP', 'Java', 'C++'], dtype=np.str)
Original Array: ['Python' 'PHP' 'Java' 'C++'] New array: ['PythonPythonPython' 'PHPPHPPHP' 'JavaJavaJava' 'C++C++C++']

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.
