Automating Knife Classification with Machine Learning

  • Lets users upload pictures into a nifty, gorgeous web-app created in Streamlit, which works great on desktop or mobile
  • Classifies pictures into 1 of 5 knife “categories”, powered by a FastAI deep learning neural network
  • Asks for user feedback, using new pictures for model re-training
  1. Why and how it works (for non-technical people!) (what you’re reading now)
  2. Training the model with FastAI (coming soon)
  3. Creating a front-end with Streamlit, hosting and production (coming soon)
