The command to run the script to train the model is: python train.py train_ecapa.yaml --device "cpu"In the future, the training script train.py can be modified to work for Intel® GPUs such as the Intel® Data Center GPU Flex Series, Intel® Data Center GPU Max Ser...

This argument is valid in YOLOv5, but not in YOLOv8. To validate the accuracy of your model on a test dataset, you can use the command yolo val model=<path to best.pt> data=<path to your .yaml file>, and make sure that you have the "val" data defined in your YAML file. You...

Learn how to write a CV that works. Our step-by-step guide offers practical advice and real-world examples to help you make a job-winning CV.
Out of the box, we have an accuracy of 80% (score). Now we have all we need to start interpreting the model. We’ll do that in the next section. Model interpretation To explain the model through SHAP, we first need to install the library. You can do it by executingpip install sh...
scores = cross_val_score(model, X, y, scoring='accuracy', cv=cv, n_jobs=-1, error_score='raise') return scores We can then report the mean performance of each algorithm, and also create a box and whisker plot to compare the distribution of accuracy scores for each algorithm. Tying ...
