WebThe models have polynomial features of different degrees. We can see that a linear function (polynomial with degree 1) is not sufficient to fit the training samples. This is called underfitting. A polynomial of degree 4 approximates the true function almost perfectly. WebBias Definition. Bias is as an undue favor, support or backing extended to a person, group or race or even an argument against another. Although bias mostly exists in the cultural …
