Web20 de ago. de 2024 · Of course I am thinking of using High Bias-Low Variance models like Naive bayes classifier or logistic regression. What I want to know is, in general which ml models perform comparatively better when it is difficult to achieve high accuracy because of the nature of the problem itself, even when having sufficient data to train on. machine … WebHigh differences in uncertainty were found in night land surface temperature (0.23) and elevation (0.13). No significant differences were found between the predicted values and their uncertainties from both models. The proposed convolution model is able to correct for a pure specification bias by presenting less uncertain parameter estimates.
