Grading

There will be several home assignments (spread over multiple weeks) on the following topics:

  • Training pipelines and code profiling
  • Distributed and memory-efficient training
  • Deploying and optimizing models for production

The final grade is a weighted sum of per-assignment grades. Please refer to the course page of your institution for details.
