#### Hot dog or not hot dog
Jìan-Yang's masterpiece from the show Silicon Valley serves as a great exercise to get
familiar with Hugging Face spaces! All the necessary files are included for everything
to run smoothly on HF's Spaces:
- app.py
- categories.txt
- model.h5 (AlexNet)
- requirements.txt
- README.md
- nay.jpg (Not-hot-dog example)
- yay.jpg (Hot-dog example)
The data used to train the model is available as a
[Kaggle dataset](https://www.kaggle.com/datasets/dansbecker/hot-dog-not-hot-dog).
The step-by-step process for generating, training, and testing the Image Classification model is
available at my [GitHub respository](https://github.com/datasith/ds-experiments-image-classification/tree/main/hotdog-not-hotdog).
If you enjoy my work feel free to follow me here on HF and/or on:

Either way, enjoy!
