I recommend using websites like https://en.wikipedia.org/wiki/Receiver_operating_characteristic#:~:text=A%20receiver%20operating%20characteristic%20curve,why%20it%20is%20so%20named to learn more about ROC curves and AUC, and how to calculate these metrics yourself. 👍 1 ohjunee commented ...
Using this concept, we can calculate the class-wise accuracy, precision, recall, and f1-scores and tabulate the results: In addition to these, two more global metrics can be calculated for evaluating the model’s performance over the entire dataset. These metrics are variations of the F1-Score...
We can import the accuracy_score method from the metric module in Sklearn and calculate the accuracy. The first argument of the accuracy_score is the actual labels, which are stored in y_test. The second argument is the prediction, which is stored in y_pred: from sklearn.metrics import a...
Metric calculations: I have a dataset of customer transactions. Please write code to calculate various customer lifetime value (CLV) metrics, such as [metrics]. Code simplification: I want you to act as a senior programmer specializing in [programming language] optimization. Please simplify this c...

The model worked well with XGBClassifier() initially, with an AUC of 0.911 for train set and 0.949 for test set. Then after I tuning the hyperparameters (max_depth, min_child_weight, gamma) using GridSearchCV, the AUC of train and test set dropped obviously (0.892 and 0.917). I feel ...
To calculate the gradient, we used the Python function numpy.gradient. The gradient provides a measure of the rate of increase or decrease of the signal; we consider the absolute value of the gradient, to account for the magnitude of change rather than the direction of change. To identify ...
1. Define a function to calculate distance between two points First, I define a function calledminkowski_distance, that takes an input of two data points (a&b) and a Minkowski power parameterp,and returns the distance between the two points. Note that this function calculates distance exactly...
This code allows you to calculate 5 of the most popular saliency metrics AUC-Judd, KLdiv, NSS, CC and Sim to determine how well a deep learning model predicted visual saliency by comparing it to a ground truth in python. This code is built on the code from FixTons and Salgan. Please...
