## Data Analytics – GGPLOT LOG SCALE TRANSFORMATION

Hits: 38 GGPLOT LOG SCALE TRANSFORMATION   This article describes how to create a ggplot with a log scale. This can be done easily using the ggplot2 functions scale_x_continuous() and scale_y_continuous(), which make it possible to set log2 or log10 axis scale. An other possibility is the function scale_x_log10() and scale_y_log10(), which transform, respectively, the x and y axis scales into a log …

## Data Analytics – TYPES OF CLUSTERING METHODS: OVERVIEW AND QUICK START R CODE

Hits: 76 TYPES OF CLUSTERING METHODS: OVERVIEW AND QUICK START R CODE   Clustering methods are used to identify groups of similar objects in a multivariate data sets collected from fields such as marketing, bio-medical and geo-spatial. They are different types of clustering methods, including: Partitioning methods Hierarchical clustering Fuzzy clustering Density-based clustering Model-based clustering   In this …

## Machine Learning Mastery: A Practical approach to Simple Linear Regression using R

Hits: 12 A Practical approach to Simple Linear Regression using R   Simple Linear Regression is a statistical method that allows us to summarize and study relationships between two continuous (quantitative) variables. One variable denoted x is regarded as an independent variable and other one denoted y is regarded as a dependent variable. It is …

## Machine Learning Mastery: Linear Regression Using Tensorflow

Hits: 33 Linear Regression Using Tensorflow   Brief Summary of Linear Regression Linear Regression is a very common statistical method that allows us to learn a function or relationship from a given set of continuous data. For example, we are given some data points of x and corresponding y and we need to learn the relationship between them that …

## Machine Learning Mastery: Linear Regression using sklearn

Hits: 300 Linear Regression using sklearn   Linear Regression is a machine learning algorithm based on supervised learning. It performs a regression task. Regression models a target prediction value based on independent variables. It is mostly used for finding out the relationship between variables and forecasting. Different regression models differ based on – the kind …

## Machine Learning Mastery: Multiple Linear Regression using Python

Hits: 189 Multiple Linear Regression using Python   Linear Regression: It is the basic and commonly used type for predictive analysis. It is a statistical approach to modelling the relationship between a dependent variable and a given set of independent variables. These are of two types: Simple linear Regression Multiple Linear Regression Let’s Discuss Multiple …

## Machine Learning Mastery: Univariate Linear Regression in Python

Hits: 12 Univariate Linear Regression in Python   Univariate data is the type of data in which the result depends only on one variable. For instance, dataset of points on a line can be considered as a univariate data where abscissa can be considered as input feature and ordinate can be considered as output/result. For …

## Machine Learning Mastery: Linear Regression (Python Implementation)

Hits: 15 Linear Regression (Python Implementation)   This article discusses the basics of linear regression and its implementation in Python programming language. Linear regression is a statistical approach for modelling relationship between a dependent variable with a given set of independent variables. Note: In this article, we refer dependent variables as response and independent variables as features for simplicity. In …

## Machine Learning Mastery: Momentum-based Gradient Optimizer introduction

Hits: 14 Momentum-based Gradient Optimizer introduction   Gradient Descent is an optimization technique used in Machine Learning frameworks to train different models. The training process consists of an objective function (or the error function), which determines the error a Machine Learning model has on a given dataset. While training, the parameters of this algorithm are initialized …

## Machine Learning Mastery: Optimization techniques for Gradient Descent

Hits: 12 Optimization techniques for Gradient Descent   Gradient Descent is an iterative optimiZation algorithm, used to find the minimum value for a function. The general idea is to initialize the parameters to random values, and then take small steps in the direction of the “slope” at each iteration. Gradient descent is highly used in …

## Machine Learning Mastery: Mini-Batch Gradient Descent with Python

Hits: 44 Mini-Batch Gradient Descent with Python   In machine learning, gradient descent is an optimization technique used for computing the model parameters (coefficients and bias) for algorithms like linear regression, logistic regression, neural networks, etc. In this technique, we repeatedly iterate through the training set and update the model parameters in accordance with the …

## Machine Learning Mastery: Stochastic Gradient Descent (SGD)

Hits: 154 Stochastic Gradient Descent (SGD)   What is Gradient Descent? Before explaining Stochastic Gradient Descent (SGD), let’s first describe what Gradient Descent is. Gradient Descent is a popular optimization technique in Machine Learning and Deep Learning, and it can be used with most, if not all, of the learning algorithms. A gradient is the …
