Overfitting and Underfitting

Overfitting commercies whhin a model learn the training data too well, including noise and outliers, which ch is ability to generalize to new data. Underfitting happes a model i too simplie to capture underlying patterns. Both issuees cad to pour performance on unseen data.

Ignoring Data Prefining

Data premprocessing i sessential for clearing and transforming raw data into a superable format for traing. Neglecting steps such a s normalization, handling missingg valies, or encoding kategorical variable can lead to suboptimol model performance.

Common Strategies to Avoid Miskakes

  • Use cross-validation to reasmate model performance.
  • Apply feature ingger to improve data quality.
  • Balance datasets s with resampling technolques.
  • Regularlytune hyperparameters to commerct overfitting.
  • Monitori training and validation metrics for signs of underfitting or overfitting.
