Custom Dataset for CSV Data

this month medium (<1 hr) | pytorch dataset dataloader tabular data

Write a PyTorch `Dataset` class that loads data from a CSV file containing tabular data (features + labels). Requirements: - Use `pandas` to read the CSV. - Convert features and labels to tensors....

Implement Dropout Manually

this month medium (<1 hr) | pytorch implementation dropout regularization

Implement dropout as a function `my_dropout(x, p)`: - Zero out elements of `x` with probability `p`. - Scale survivors by $$1/(1-p)$$. - Ensure deterministic behavior when `torch.manual_seed` is...

Custom Activation Function

this month medium (<1 hr) | pytorch implementation activations mlp

Define a custom activation function called `Swish`: $$f(x) = x \cdot \sigma(x)$$. - Implement it as a PyTorch `nn.Module`. - Train a small MLP on random data with it. - Compare with ReLU...

Visualize Training with TensorBoard

this month medium (<1 hr) | pytorch training tensorboard visualization

Integrate TensorBoard into a training loop: - Log training loss and validation accuracy. - Add histograms of weights and gradients. - Write a few sample images. Open TensorBoard and verify logs.

Implement Early Stopping

this month medium (<1 hr) | pytorch training basics early stopping

Add early stopping to a training loop: - Monitor validation loss. - Stop training if no improvement after 5 epochs. - Save best model checkpoint. Demonstrate on MNIST subset.
