Machine Learning (ML) Types of RNN (Recurrent Neural Network) In this article, we shall dive into Recurrent Neural Networks types after getting you briefly introduced to RNNs. In short, the different types of RNN are one to one, one to many, many to many and many to one.
Machine Learning (ML) Understand different types of Boosting Algorithms In this article we will dive deep into understanding Boosting and then we are going to see rapidly some derived algorithms like AdaBoost and LightGBM.
Algorithms Find the number of subsets with given Bitwise OR value We are given an array of size N and a value M, we have to find the number of subsets in the array having M as the Bitwise OR value of all elements in the subset. This can be solved using Dynamic Programming in polynomial time.
Software Engineering Measure time in C++ In this article at OpenGenus, we explored different methods to measure time in C++ which includes time(), clock() and chrono library. This can be used to measure program execution time as well.
Software Engineering Data types in JavaScript JavaScript is a loosely typed language. According to the latest ECMAScript standard, there are eight data types defined in JavaScript like boolean, null, undefined, bigint and much more.
Software Engineering Generate executable from Python file using PyInstaller In this article we have explained how we can use PyInstaller to create standalone executable from our python applications. We have demonstrated this using a real life codebase.
Algorithms Find minimum number of deletions to make a string palindrome We need to find the minimum number of characters to be deleted in a string to make it a palindrome. This can be done in O(N^2) time with the help of Dynamic Programming approach of Longest Palindromic Subsequence.
Data Communication and Computer Networks Understanding Internet using ISO OSI model In this article, we will understand how the Internet works using the ISO OSI model of networking. We will begin by understanding the ISO OSI model followed by an example.
Software Engineering Different ways to handle Input and Output in Java Java handles input and output through streams and there are multiple input and output streams specialized for different use cases like BufferedOutputStream and much more which we have explored in depth in this article at OpenGenus.
Algorithms Minimum insertions to make the frequency of each character unique We developed a string algorithm to find out the minimum number of insertions to be made in a string so that the frequency of each character is unique
Algorithms Longest Common Subsequence In this problem, we solved the Longest Common Subsequence problem using Dynamic Programming which takes O(N*M) time while a brute force approach takes O(2^N) time
Algorithms Longest Common Substring in two strings In this problem, we explored a Dynamic Programming approach to find the longest common substring in two strings which is solved in O(N*M) time. Brute force takes O(N^2 * M) time.
Machine Learning (ML) Topic Modeling using Non Negative Matrix Factorization (NMF) Non-Negative Matrix Factorization is a statistical method to reduce the dimension of the input corpora. It uses factor analysis method to provide comparatively less weightage to the words with less coherence.
Machine Learning (ML) Sentiment Analysis Techniques Sentiment Analysis is the application of analyzing a text data and predict the emotion associated with it. This is a challenging Natural Language Processing problem and there are several established approaches which we will go through.
Software Engineering Generate all combinations taking one element from each list in Python Generating all combinations taking one element from each list in Python can be done easily using itertools.product function. It is a part of itertools module
Software Engineering chdir(), fchdir() and getcwd() in C chdir() and fchdir() are functions in C listed in unistd.h header file which is used to change the current working directory through code. This can be verified by getcwd() function.
Software Engineering Everything you need to know about Conda in Python In this guide, we have explored everything about Conda along with a cheatsheet of commands. We have covered conda package structure and how it works internally as well.
Algorithms Evolution of Integer Multiplication Algorithms (from 1960 with end in 2019) We started with an O(N^2) time Integer Multiplication algorithm and it was the first time ever in 1960 that we developed an faster Integer Multiplication algorithm which ran at O(N^1.58) time and now in 2019, we are nearly at the end of this domain with O(N logN) time algorithm.
Algorithms Research papers on Integer Multiplication (1960 to 2019) hese are the papers that you should read and understand to understand how we have improved Integer Multiplication over the years and now in 2020, we are on the verge of completing this domain once for all.
Machine Learning (ML) Topic Modeling using Latent Semantic Analysis In this article, we have explored the functioning and working of Latent Semantic Analysis with respect to topic modeling in DEPTH along with mathematics behind the method.
Machine Learning (ML) Residual Neural Network (ResNet) Residual neural networks or commonly known as ResNets are the type of neural network that applies identity mapping to solve the vanishing gradient problem and perform better than RNN and CNN.
Legends of Computer Science Hans Peter Luhn, the man behind Hash Map Hans Peter Luhn was a computer scientist who is famously remembered as the inventor of Hash Map and has laid the foundations of text information processing.
Machine Learning (ML) Text Summarization using RNN Encoder Decoder RNN (Recurrent neural network) model is used in order to overcome all the limits faced by the NLP for text summarization such as getting a short and accurate summary.
Algorithms Rod cutting problem In this article, we explored the rod cutting problem in depth which can be solved using a Dynamic Programming approach that takes O(N^2) time and O(N) space
Software Engineering push() in Stack C++ STL We have discussed about how we can insert elements in stack container using push() method provided by C++ STL(Standard Template Library).
