Main Files:
scraping_data.ipynb: Uses Selenium for extracting/scraping data from the NBA website.
nba_team_stats_cleaned.ipynb: Transforms and loads data tables into SQL.
NBA_Analysis.ipynb: Pulls data from SQL tables, prepares the data for the neural network model, and generates a prediction for an upcoming game. There is an option to choose whether or not to add post-season data to the model. The main model is created using TensorFlow with manual inputs. This model is compared to a KerasTuner automated optimization search. There are other models utilized in the "Alternate Experiments" section.
Use:
Run scraping_data.ipynb to generate CSVs from the NBA stats pages. Then run nba_team_stats_cleaned.ipynb to transform and load the tables into SQL. Finally, open NBA_Analysis.ipynb, choose your favorite set of parameters to run the models with, and run the cells.
