Introduction

With the growing popularity of music streaming services like Spotify, Apple Music and Wynk, the number of songs have skyrocketed globally. Creating personalized playlists for users has become tedious and challenging as it involves individual listening to various songs and categorizing them based on their audio features. The objective is to sort songs with similar musical characteristics into playlists automatically. Modern machine learning techniques and visualization tools should help us find accurate models that categorize millions of songs into user playlists based on song choices. Related works on this problem did not consider Lyrical Analysis while making playlists. We are using Topic Modelling techniques on lyrics, and will be using the extracted topics as a feature for generating playlists.

Description and Implementation Details

In this repository, we have implemented vairous machine learning aglorithms on Topic Extracted from the lyrical corpus.

• DataScrape - Dataset, Data Collecction code, pre-processing and topic modeling
  
• PreProcessing - Code for Visualisation
• models - binary classification , multi classification , clustering, K-nearest Neighbours source code with the respective models saved with the results also saved.

How to Run ?

The models pickles are saved in "rb" format in their respeective directories (\models directory).

• To load the models

  f = open("model_name", "rb")
  load_model = pickle.load(f)
  f.close()
  

• To test the models

  • Clustering Models - They are simple pickled files of the models which can be executed and evaluated by the following code .

    model.predict(X_test)
    

  • Multi classification Models - hey are simple pickled files of the models which can be executed and evaluated by the following code.

    model.predict(X_test)
    

  • Binary Classification Models - It is a list of all the one vs all models which can be executed and evaluated using the following code.

     pred = []
     for i in range(len(load_model)):
         pred.append(load_model[i].predict(X_test))
    
     pred.argmax(axis = 1)
    

• Generate Graphs for the Analysis

  • Each graph can be plotted from the ipynb files in the directories, the code is documented for one to understand and plot the respective graphs.
