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.

Destructors in C++

A destructor in C++ is a member function associated with each class and is called when the scope of the object of the classes is over to delete all data allocated for the object.

Algorithms

Scheduling tasks to Minimize Lateness

In this article, we have explored techniques to schedule tasks (with a deadline and time required to complete it) in a way to decrease the time lag in finish time and deadline of the chosen request (i.e., lateness).

Contrast Enhancement Algorithms

This article covers: Contrast and Contrast Enhancement, Types of Contrast Enhancement: Histogram Equalization, Contrastive Limited Adaptive Equalization, Contrast Stretching and how to implement these in Python using OpenCV.

Algorithms

Smallest Missing Positive Integer

The problem is to find out the smallest missing positive integer given an unsorted integer array. We can solve this problem in linear time O(N) and in constant time O(1) using a greedy approach with hash map.

Difference between public, private, protected and default in Java

In the article, we have covered the differences between various types of access specifiers like public, private, protected and default in Java in detail.

Machine Learning (ML)

Different Word Representations

We have discussed the different word representations such as distributional representation, clustering based representation and distributed representation with several sub-types for each representation.

Software Engineering

Types of Exceptions in Java

In this article, we have explored the different types of exceptions in Java. The main types are checked and unchecked exceptions. By definition, the types are build-in exceptions and user defined exceptions.

Basics of OAuth 2.0

OAuth 2.0 is an authorization framework or protocol that grants a API clients (third-party applications) a limited access to protected web resources of users on a HTTP service provider, such as Twitter, Instagram and LinkedIn.

Software Engineering

Basics of OAuth 1.0

OAuth 1.0 is an open-standard authorization protocol or framework that allows third-party applications (and websites) have access to a user's information on a website or application without (the user) sharing their password. We have explored OAuth 1.0 in depth.
