9 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. Loss Function ✓ understood

    A function that scores how wrong a model's prediction is as a single number, which training then works to make as small as possible.

  6. Gradient Descent ✓ understood

    An optimization method that repeatedly moves a model's parameters a small step in the direction that most reduces the loss.

  7. Momentum ✓ understood

    An optimization technique that accelerates gradient descent by accumulating past gradients, helping escape local minima.

  8. Learning Rate ✓ understood

    A hyperparameter controlling the step size in gradient descent - too high causes instability, too low slows convergence.

  9. Adam Optimizer ✓ understood

    An adaptive learning rate optimization algorithm combining momentum and RMSprop, widely used for training neural networks.
