If you have used machine learning to perform classification, you might have heard aboutSupport Vector Machines (SVM). Introduced a little more than 50 years ago, they have evolved over time and have also been adapted to various other problems likeregression, outlier analysis,andranking. ...

Support Vector Machine using Python In the previous article, we studied the K-Means Clustering. One thing that I believe is that if we can correlate anything with us or our lives, there are greater chances of understanding the concept. So I will try to explain everything by relating it to...
