8 Important Evaluation Metrics for Classification Models

Posted on March 26, 2020 by Sandeep Kumar

This post explains important evaluation metrics to check while measuring the performance of a classification model. These are Accuracy, Precision, Recall, Sensitivity, Specificity, False Positive Rate, False Negative Rate, and F1 Score. We’ll cover one by one each metric by calculating its value u...

Understand Confusion Matrix Using Real-life Classification Example

Posted on March 25, 2020 by Sandeep Kumar

First I’d like to explain what is the use of a confusion matrix. Classification Problems are solved using Supervised Machine learning algorithms. In these problems, our goal is to categories an object using its features. For e.g, Identify a fruit using its taste, color and size or check out ...

Explain Echelon Form of a Matrix

Posted on February 26, 2020 by Sandeep Kumar

Echelon Form of a matrix is used to solve a linear equation by converting a complex matrix to a simple matrix. A matrix is in an Echelon Form if it satisfies some conditions which we’ll discuss in this post. We must know how to convert a matrix into Echelon Form and simplify our matrix for [&h...

Working of Bagging and Boosting in Ensemble Learning

Posted on February 10, 2020 by Sandeep Kumar

Bagging and Boosting both are Ensemble Learning techniques. Ensemble Methods are an important addition to Data Scientists toolbox. Here, weak learners combined together to become strong learners. And offers better performance than an individual one. What is an Ensemble Method The main logic behind t...

What is the difference between Variance and Bias in Machine Learning?

Posted on February 8, 2020 by Sandeep Kumar

From the perspective of Supervised Machine Learning, we know all models have errors. We need to minimize the error so as to make the model useful. For this, we need to minimize two major sources of error- Bias and Variance. What is Bias? The tendency of the algorithm to learn wrong details from the ...

Decision Tree vs Random Forest in Machine Learning

Posted on February 8, 2020 by Sandeep Kumar

Machine Learning is the sub-branch of Artificial Intelligence. It gives a system the ability to learn and become better from past experiences. Decision tree and random forest are two Supervised Machine Learning techniques. A decision tree is a simple and decision-making diagram. Certainly, for a muc...
