29 Views

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

Big Data Big data alludes to the enormous volume, variety, and velocity of data created from different sources, including web−based entertainment, sensors, and cell phones, and that's just the beginning. The expression "big" includes the sheer volume of data and addresses the data's intricacy and variety. Big data is portrayed by its three V's − Volume Big data includes a huge amount of data that outperforms the handling abilities of conventional data set systems. The scale goes from terabytes (~ all of your PC extra room) to exabytes (~ all of your extra room X a million) and then some. ... Read More

## Gradient Descent in Linear Regression

Updated on 24-Aug-2023 12:36:24

51 Views

The use of linear regression is a useful technique for figuring out and examining the relationship between variables. Predictive modeling relies on it and uses it as the cornerstone for many machine learning techniques. Machine learning requires a lot of optimization. It is comparable to improving a model to provide it with the best performance. Gradient descent, a key technique in optimization, enters the picture at this point. Consider it as a trustworthy ally that will help us navigate the vast array of potential model parameters to find the optimal ones. Gradient descent allows us to iteratively change these ...
