How can I calculated summary stats based on weighted data in R? (AUC, MSE, MAE, R2, etc.)
I'm creating a Shiny dashboard app. One of the features on this app is a stat table that shows the MSE, MAE and either AUC or R2 depending on which is relevant.
These stats are currently just based on the data, treating each row equally. However,…

Value of PSNR if MSE = 0
What should be the value of PSNR(Peak Signal to Noise Ratio) be when MSE(Mean Square Error) is 0 ? I am getting error when rmse = 0. So , what changes could be done to improve and get the psnr value even when rmse is zero ?
Following is my code for…

CV results of Desicion Tree test mse 0.0000578 and train mse 0
I'm working on a small data set (25 rows, 4 features). I trained the decision tree algorithm and used K-fold cross-validation (cv=3). Then, I obtained r2 0.97 for this reason, I suspected overfitting and looked at the test and train MSE values. I…

Is there a better way to calculate loss for multi-task DNN modeling?
Suppose there are over one thousand tasks in the multi-task deep learning. More than a thousand columns of labels. Each task (column) has a specific weight in this case. It would take such long time to loop over each task to calculate the sum of…

Poisson Model (Binary Response) Evaluation Metrics
I am unsure about the correct evaluation metrics to use in my model, and would appreciate your advice.
Model Info:
I fitted a GLM Poisson model in Python on a dataset, where each row of data has a different exposure between 0 to 1 and the response…

MSE, is it correct to use evaluate with unscaled data in Tensorflow Keras?
Suppose you have numerical time series data and you managed to split it like:
X_train, y_train, X_val, y_val, X_test, y_test.
and you properly scaled everything ending up with:
X_train_scaled, y_train_scaled, X_val_scaled,…

how to compute the MSE?
I have to compute the MSE of the value "Td" without packaging. I used a function but I have always the same MSE (see MSE_mod1) for each row (it shouldn't be the same MSE between lines, right?). Do you know why?
Could you help me? :)
Here is my…

Questions about feature selection and data engineering when using H2O autoencoder for anomaly detection
I am using H2O autoencoder in R for anomaly detection. I don’t have a training dataset, so I am using the data.hex to train the model, and then the same data.hex to calculate the reconstruction errors. The rows in data.hex with the largest…

Fit quadratic function to data using MSE
So my idea is (borrowed from neural network folks) that if I have data set D, I can fit a quadratic curve to it by first calculating the derivative of the error with respect to the parameters (a, b, and c), and then do a small update that minimizes…
