Depthwise Convolution op in TensorFlow (tf.nn.depthwise_conv2d)

This article will discuss about the Depthwise Convolution operation and how it is implemented using the TensorFlow framework (tf.nn.depthwise_conv2d).

Depthwise Convolution is one part of the Depthwise Separable Convolution that comes under the separable convolution techniques. In many neural network architectures depth-wise separable convolutions are preferred over normal convolutions. These kind of convolutions are used in convolutional neural networks (CNNs) designed for mobile and embedded a...

KL Divergence

In this article , one will learn about basic idea behind Kullback-Leibler Divergence (KL Divergence), how and where it is used.

INTRODUCTION

Hola everyone! Most of us know to do code using list, tuple and dictionaries in python separately without any confusions, but when we came to work with all the three together we would get confused, so to avoid...

Finite Automata in Theory of Computation

In this article, we discuss finite automata, a state machine that takes a regular expression and changes its state accordingly for each literal and when the transitions reach the final state, the string is accepted and thus it is said to be a valid token of a language.

Basics of Theory of Computation: Mathematical foundation and proofs

In this article we introduce the theory of computation and lay the foundation for articles to come by going over mathematical concepts and how to prove theorems which will deem useful in understanding the domain of compiler design.

Table of contents.Introduction.Mathematical groundwork.Proofs.Summary.References.Introduction.

The purpose of the theory of computation is to develop mathematical models of computation which reflect real-world machines.

It aims to answer questions such as the ...

Integer (Int Variable) in Python

In this article, we have explored Integer (Int Variable) in Python in depth along with complete Python code examples.

Table of Contents:

Introduction to variablesWhat are integer variables?How can we manually create int variables?1. Introduction to Variables

What exactly are variables, and why should we care about int variables? We'll go over such topics in this article and more.

First, variables in programming can be defined as reserved memory locations - or points - that store information...

Types of Programming Languages

In this article, we discuss the different major types of programming languages that is High and Low-Level Languages, how they are used, and their pros and cons.

Table of contents.Introduction.High-level languages.Mid-level languages.Low-level languages.Summary.References.Introduction.

There are three major categories of of computer programming languages namely:

High level(Java, Haskell, Prolog, FORTRAN)Mid level(C, Assembly).low level(Assembly, Machine code).

High level languages....

Introduction to Compiler Design

A compiler is responsible for translating high-level source code into low-level code. In this article, we go over a brief overview of the compiler design domain, a very successful field of computer science.
