Boolean and None in Python

"if x" and "if x is not None" are not equivalent - the proof can be seen by setting x to an empty list or string. In this article, we have explored the two important concepts namely boolean and none in Python.

MaxPool vs AvgPool

In this article, we have explored the difference between MaxPool and AvgPool operations (in ML models) in depth. In short, in AvgPool, the average presence of features is highlighted while in MaxPool, specific features are highlighted irrespective of location.

Purpose of different layers in a Deep Learning Model

In this article, we have explored the significance or the importance of each layer in a Machine Learning model. Different layers include convolution, pooling, normalization and much more. For example: the significance of MaxPool is that it decreases sensitivity to the location of features.

Software Engineering

Variable scope in Python

The variable scope in Python is the part of a program where a variable is accessible. A variable can be accessed within the region it is defined, we call this it's scope.
