4 stops · basics first
  1. GPU ✓ understood

    Graphics Processing Unit - hardware accelerator with thousands of cores, essential for parallel computation in deep learning.

  2. Dataset ✓ understood

    A collection of data examples used for training, validating, or testing machine learning models.

  3. Training ✓ understood

    The process of fitting a model to data by repeatedly measuring how wrong its outputs are and adjusting its parameters to reduce that error.

  4. Data Parallelism ✓ understood

    Replicating the model across devices, each processing different data batches.

  5. Sharded Data Parallelism · you are here ✓ understood

Distributing model states across devices to train models larger than single-device memory.

This concept is essential for understanding training & optimization and forms a key part of modern AI systems.
