📘 ExplainedVistaar se

Signs: low scores on both training and validation data, and errors that follow an obvious pattern the model ignores. It's the opposite of overfitting. Fixes: add better features, use a more flexible model (for example gradient boosting instead of a straight line), train longer, or reduce regularisation.Lakshan: training aur validation dono data pe kam score, aur aisi galtiyaan jinka saaf pattern model ignore karta hai. Yeh overfitting ka ulta hai. Upaay: behtar features jodo, zyaada flexible model lo (jaise seedhi line ke bajaye gradient boosting), zyaada der train karo, ya regularisation kam karo.
