⚡ Libraries allowed · Pure Python earns +10 bonus XP
🎯 Mission
Implement Practice: Categorical Cross-Entropy Loss From Scratch and verify your implementation in the interactive AI/ML IDE workspace.

Task

Implement `categorical_cross_entropy`. Libraries (NumPy, PyTorch, SciPy) are allowed, but Pure Python implementations earn bonus XP!

Function Signature

categorical_cross_entropy(*args, **kwargs)

Examples

Example 1: Smoke Test
Input: {}
Output:
Explanation: Executes your function against default test inputs.

Constraints

  • Libraries (NumPy, PyTorch, SciPy) are allowed and accepted normally.
  • Pure Python (no external libraries) earns +10 Bonus XP!
  • Must handle edge cases (empty inputs, invalid shapes, boundary conditions) correctly.
