Introduction TensorBoard is a tool that provides measurements and visualizations needed during machine learning workflow. In this tutorial, I will give a quick tutorial on how to visualize your feature vectors on TensorBoard. Using a machine learning model, sometimes we want to learn embeddings of different classes. Embeddings are a way…

A step-by-step tutorial to explain the working of PCA and implementing it from scratch in python — Introduction Principal Component Analysis or PCA is a commonly used dimensionality reduction method. It works by computing the principal components and performing a change of basis. It retains the data in the direction of maximum variance. The reduced features are uncorrelated with each other. These features can be used for unsupervised…

A step-by-step implementation to classify audio signals using continuous wavelet transform (CWT) as features. Introduction Audio classification is a very important task. In the past decade, a lot of research has been done on classifying audio using different kinds of features and neural network architectures. Some real-world applications of this are…
