How can the exact same model give different confusion matrices for the test dataset and the entire dataset?
I have recently implemented a simple artificial neural network with 1 hidden layer. I split my data using train_test_split and I end up with the following confusion matrix in my test set.
Confusion matrix:
[[193 14]
[ 24 169]]
Accuracy score is…

Binary Classification Model Comparison - Interpretation of Training, Test and Validation Set Performance
I am looking for some advice regarding the best choice of binary classification model based on training, validation and test set results. Model 1 (results in 1st image) shows better test set results than Model 2, but Model 2 (results in 2nd image)…

Metrics using batches v/s metrics using full dataset
I am using training an image classification model using the pre-trained mobile network. During training, I am seeing very high values (more than 70%) for Accuracy, Precision, Recall, and F1-score on both the training dataset and validation…

Confusion Matrix Measures vs Accuracy level in Neural Network Model
I'm working on a classification machine learning problem with two classes: high and low, which are derived from another numerical column x. Previously, if x>100, the sample is considered high, otherwise, it is considered low. I used a 1D CNN…
