Problem - solving ie Machina Learning Przewodniczący: Troubleshooting Overfitting andUnderfitting
Machine uczy się models can face issues such as s overfitting and d underfitting, which affect their ir performance. Troubleshooting these problems involves understanding the causes andd applicying appropriate solutions to improwize model customacy and generalization.
Understanding Overfitting andUnderfitting
Overfitting events when a model learns the couring data too well, including ding noise andd outriers, leading to pour performance on new data. Underfitting hapins when a model is too simple to o capture the underlying Patterns, resulting in low closiacy on both training and testing data.
Sigs of Overfitting andUnderfitting
Wskaźniki of overfitting included high training closiety but low testing closiacy. Underfitting is criterized by both training and testing closies being low similar. Monitoringg these metrics helps identify the problem.
