Introduction Cross Validation (CV) is a way of training machine learning models in which multiple models are trained on a part of the data and then accessing their performance or testing them on a independent unseen set of data. In the Cross-validation technique, we generally split the original train data into different parts iteratively so that the algorithm trains and validates itself on each portion of the data none of them are left out in the process In this article let us have a deep good understanding of the Cross-Validation technique and its significance in improving Model accuracy. Cross Validation ... Read More

Introduction Normality is defined as the phenomenon of belonging to a normal or Gaussian distribution in statistical terms. The normality of a dataset is the test for a dataset or variable if it follows a normal distribution. Many tests can be performed to check the normality of a dataset among which the most popular ones are the Histogram method, the QQ plot, and the KS Test. Normality testing – Checking for Normality There are both statistical and graphical approaches to determining the normality of a dataset or a feature. Let us look through some of these methods. Graphical Methods Histogram ... Read More

Introduction OOB or Out of Bag error and OOB Score is a term related to Random Forests. Random Forest is an ensemble of decision trees that improves the prediction from that of a single decision tree.OOB error is used to measure the error in the prediction of tree-based models like random forests, decision trees, and other ML models using the bagging method. In an OOB sample, the number of wrong classifications is an OOB error. In this article let's explore OOB error/score. Before moving ahead let us a short overview of Random Forest and Decision Trees. Random Forest Algorithm Random ... Read More

Introduction Fixed basis functions are functions that help us to extend linear models in Machine Learning, by taking linear combinations of nonlinear functions. Since Linear models depend on the linear combination of parameters, they suffer a significant limitation. The radial function thus helps model such a group of models by utilizing non-linearity in the data while keeping the parameters linear. Different linear combinations of the fixed basis functions are used within the linear regression by creating complex functions. In this article let us look into the fixed basis function and its limitations Fixed Basis function A linear regression model ... Read More

HTML employs predefined tags to instruct the browser on how to display the content. Tags are nothing more than a few instructions that are encased in angle brackets (i.e., ). Although tags are utilized across a website, many visitors are frequently unclear as to whether a given tag is a container or empty tag. They are confused since they are unsure of which tags require an ending tag in addition to the opening tag. In HTML, there are two different categories of tags − Empty Container Now, let's dive into the article for getting better understanding on container ... Read More
