This repository contains the source code and the documentation for my project at Stanford University. In this project, I tried to implement a neural network which is capable of predicting a song genre based on a few sentences of song text.
The software is implemented as jupyter notebook and uses Tensorflow and Keras.
The final paper can be found here.
The per class accuracy is as follows:
Per Class accuracy for Country is 48.9 %
Per Class accuracy for Pop is 52.6 %
Per Class accuracy for Rock is 9.9 %
Per Class accuracy for R&B is 8.2 %
Per Class accuracy for Hip-Hop is 85.5 %
Per Class accuracy for Electronic is 09.3 %
Per Class accuracy for Jazz is 0.0 %
Here are a few examples of the input and the generated output:
