## Singular Value Decomposition for Dimensionality Reduction

Singular Value Decomposition usually referred to as SVD, is a type of matrix decomposition technique that is popularly used to reduce the dimensions of the data. SVD decomposes a mxn real matrix A into a product […]

## WordClouds in Python

In this article, we are going to see how to create a word cloud in python. A word cloud creates a collage of most prominent words from the given text. The size of each word is […]

## KERAS Callbacks

Keras comes with a long list of predefined callbacks that are ready to use. Keras callbacks are functions that are executed during the training process. According to Keras Documentation, A callback is a set of functions to be […]

## Types of Data

It is necessary to understand the different types of data we are dealing with to choose the right visualization technique or statistical measure for our data. In this blog post, we’ll discuss two types of data […]

## Introduction to Hyper-parameter Tuning: GridSearchCV and RandomSearchCV

Most of the machine learning algorithms contain a number of hyperparameters that we can tune to improve the model’s performance. The hyperparameter controls the behaviors of the algorithm and has an enormous impact on the results. […]

## Measure of Central Tendency and Measure of Spread

Summarizing the quantitative data can help us understand them better. In this article, we’ll see various methods to summarize quantitative data by the measure of central tendency(such as mean, median, and mode) and by the measure […]

## Why High Dimensional Data are a Curse?

In the era of big data, massive datasets(not only in the number of samples being collected but also in the number of features) are increasingly prevalent in many disciplines and are often difficult to interpret.  In […]

## Converting Raw Text to Numerical Vectors using Bag of Words, N_Grams and TF-IDF

If we are dealing with text documents and want to perform machine learning on text, we can’t directly work with raw text. We first need to convert the text into numbers or vectors of numbers. In this article, […]

## Introduction to Logistic Regression

In this article, we’ll discuss a supervised machine learning algorithm logistic regression. Logistic regression is a probabilistic classifier. It outputs the probability of a point belonging to a specific class. The output lies between [0,1]. Logistic […]
