WebApr 20, 2024 · The equation of the curve is as follows: y = -0.01924x4 + 0.7081x3 – 8.365x2 + 35.82x – 26.52 We can use this equation to predict the value of the response variable based on the predictor variables in the model. For example if x = 4 then we would predict that y = 23.32: y = -0.0192 (4)4 + 0.7081 (4)3 – 8.365 (4)2 + 35.82 (4) – 26.52 = 23.32 WebApr 30, 2016 · history = model.fit (X, Y, validation_split=0.33, nb_epoch=150, batch_size=10, verbose=0) You can use print (history.history.keys ()) to list all data in history.
