Ridge's r2

TīmeklisThe coefficient of determination R 2 is defined as ( 1 − u v), where u is the residual sum of squares ( (y_true - y_pred)** 2).sum () and v is the total sum of squares ( (y_true - y_true.mean ()) ** 2).sum () . The best possible score is 1.0 and it can be negative (because the model can be arbitrarily worse). Tīmeklis2024. gada 13. okt. · Ridge Regression透過將懲罰參數λ∑pj=1β2j加入目標函式中。 也因為該參數為對係數做出二階懲罰，故又稱為L2 Penalty懲罰參數。 而L2懲罰參數的值可以透過「tuninig parameter, λ」來控制。 當λ→0，L2懲罰參數就跟OLS回歸一樣，目標函式只有最小化SSE； 而當λ→∞時，懲罰效果最大，迫使所有係數都趨近於0。 from …
