However, sklearn metrics can handle python list strings, amongst other things, whereas fastai metrics work with PyTorch, and thus require tensors. If you are playing football and you always hit the right goal post instead of scoring, then you are not accurate, but you are precise!. Making model better¶ ¶ Generally, when you call fit_one_cycle it only trains the last or last few layers. The most common is ResNet34, due to it’s balance of speed and accuracy.

Once we run the model, we can use our plot top losses in both training and validation datasets to figure out where the model got things wrong. If you get a depressing model accuracy, do this: fix eta = 0. A R function for "Accuracy" in a classification response prediction was created. compute accuracy measures (test set) accuracy. We end up with a trace containing sampled values from the kernel parameters, which can be plotted to get an idea about the posterior uncertainty in their values, after being informed by the data. Clean up the data for model; In previous step, we read the news contents and stored in a list. Create a Callback that handles the hyperparameters settings following the 1cycle policy for learn. The top-1 and top-5 accuracy refers to the model's performance on the ImageNet validation dataset.
