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 Today Machine Learning plays a crucial role in predicting stock prices and the growth of popular organizations and investment banks. While working on many such problems we consider many relations and correlations between different kinds of factors. The Anne Hathaway Effect is one such peculiar correlation related to popular businessman and investor Warren Buffet, Anne Hathaway, and his company Berkshire Hathaway(BRK). In this article let us know more about the effects and observations around this phenomenon. The Anne Hathaway Effect The Hathaway effect news was first picked up by CNBC. According to this effect, whenever Anne ... Read More
Introduction Similarity metrics are crucial in Recommendation Systems to find users with similar behavior, pattern, or taste. Nowadays Recommendation systems are found in lots of useful applications such as Movie Recommendations as in Netflix, Product Recommendations as in Ecommerce, Amazon, etc. Organizations use preference matrices to capture use behavioral and feedback data on products on specific attributes. They also capture the sequence and trend of users purchasing products and users with similar behavior are captured in the process. In this article, let's understand in brief the idea behind a recommendation system and explore the similar techniques and measures involved in ... 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
CSS can be used to make HTML hidden components visible when hovered over. This article will teach you how to reveal the hidden elements. Utilizing an adjacent sibling selector, we can use CSS to display any HTML element when the user hovers above the tag. When selecting an element that is close to or adjacent to a specific selector tag, the adjacent sibling selector is used. This combinator only chooses one tag that is adjacent to the target tag. Let's dive into the article for getting better understanding on displaying element on hovering over tag using CSS. ... 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
