What is Underfitting in Applied AI?
When a model is too simple or too undertrained to capture the structure in the data. Both training and validation error stay high. The fix is usually a larger model, more training, better features, or a different architecture entirely.
Why Underfitting Matters for Your AI or Cybersecurity Career
Underfitting is the failure mode behind models that ship and then never produce useful predictions. Diagnosing it early saves teams from blaming data when the architecture is wrong.
