Overfit the data

WebFor example, linear models such as ANOVA, logistic, and linear regression are usually relatively stable and less of a subject to overfitting. However, you might find that any particular technique either works or doesn't work for your specific domain. Another case when generalization may fail is time-drift. The data may change over time... WebOct 25, 2024 · Because regularization causes J (θ) to no longer be convex, gradient descent may. not always converge to the global minimum (when λ > 0, and when using an. appropriate learning rate α). Using too large a value of λ can cause your hypothesis to underfit the data; this can be avoided by reducing λ.
