How to find the pairwise correlation coefficients of columns of a pandas DataFrame?

by Amrita Mitra | Nov 9, 2022 | Machine Learning Using Python, Python Pandas

the slice object “:” indicates that all the rows are selected for the given columns. Also, df2.iloc[:, [0, 1]] returns a DataFrame that has two columns and three rows. As a result, df2.iloc[:, [0, 1]].corr() will compute correlation coefficients of only column 0 and column 1 of the DataFrame.

The output of the above program will be:

DataFrame: 
    0   1  2      3
0  10  12  A   True
1  52  61  B  False
2   9  10  C   True
Correlation Coefficients of column 0 and column 1: 
           0         1
0  1.000000  0.999898
1  0.999898  1.000000

We can interpret the correlation matrix in the same way that we discussed before.

In one of our previous articles, we already discussed what the Hadamard product in linear algebra is. We discussed that if A and B are two matrices of size mxn, then the Hadamard product of A and B is another mxn matrix C such that: $latex H_{i,j}=A_{i,j} \times...

Perform tensor addition and subtraction using Python

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

We can use numpy nd-array to create a tensor in Python. We can use the following Python code to perform tensor addition and subtraction. import numpy A = numpy.random.randint(low=1, high=10, size=(3, 3, 3)) B = numpy.random.randint(low=1, high=10, size=(3, 3, 3)) C =...

How to create a tensor using Python?

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

What is a tensor? A tensor is a generalization of vectors and matrices. It is easily understood as a multidimensional array. For example, in machine learning, we can organize data in an m-way array and refer it as a data tensor. Data related to images, sounds, movies,...

How to combine NumPy arrays using horizontal stack?

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

We can use the hstack() function from the numpy module to combine two or more NumPy arrays horizontally. For example, we can use the following Python code to combine three NumPy arrays horizontally. import numpy A = numpy.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) B =...

How to combine NumPy arrays using vertical stack?

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

Let’s say we have two or more NumPy arrays. We can combine these NumPy arrays vertically using the vstack() function from the numpy module. For example, we can use the following Python code to combine three NumPy arrays vertically. import numpy A = numpy.array([[1, 2,...

Singular Value Decomposition (SVD) using Python
