The dataset we will use in this tutorial is the Sonar dataset.This is a dataset that describes sonar chirp returns bouncing off different services. This is a multi-class classification problem, meaning that there are more than two classes to be predicted, in fact there are three flower species. This is a classic case of multi-class classification problem, as the number of species to be predicted is more than two. Multiclass classification with keras(Tensorflow) Deep Learnin g. Target vector. Before getting started with our code, let’s import all the required libraries. In the previous blog, we discussed the binary classification problem where each image can contain only one class out of two classes. Now Keras is a Python library for deep learning that wraps the efficient numerical libraries Theano and TensorFlow. The dataset we’ll be using in today’s Keras multi-label classification tutorial is meant to mimic Switaj’s question at the top of this post (although slightly simplified for the sake of the blog post).Our dataset consists of 2,167 images across six categories, including: 1. We use it to build a predictive model of how likely someone is to get or have diabetes given their age, body mass index, glucose and insulin levels, skin thickness, etc. i) RNN has a memory that captures what has been calculated so far.
