Understanding Bias and Variance

Bias refers to errors introduede by approximating a real- world probleme with a simplified model. High bias car after fitting, where the model fail to captura underlying patterns. Variance, on the othel hand, mequures how much the model 's prediks change with differt trainig data. High varianche cae can lead to overfitting, wherle mod moge noe noe sige sige.

Stratégia to Reduce Bias

To persente bias, consider using more complex models or incompeting the number of features. Techniques such a s polinomial regression or deep learningg models can bettur captura patters. Additionally, gathering more excellenant data help the model learn more pointately.

Stratégia to reduce variance

A methods like pruning deciton trees, using dropout in neurál networks, or apucying L2 regularization can overfitting. Cross- validation also helps in tuning model to incomplexity to generalization.

Practical Tips for Balancing Bias and Variance

  • Use cross-validation to reasmate model performance.
  • Apply regularization technokes to infott overfitting.
  • Adjust model complexity based od on data size and variability.
  • Gather more data to improve model learninge.
  • Monitoros bias and variante metrics during trininig.
