레코드가 많은 곳은 undersampling, 적은 곳은 oversampling.
이후 y 값이 낮은 곳 undersampling, 높은 곳 oversampling.
하기전에 minmax 하자.
1. 많은 곳이거나 y값이 낮으면 undersamling, 적은 곳이거나 y값이 높으면 oversampling하면 test data분포를 정확히…

Developed a machine learning model to detect fraudulent credit card transactions with 93% accuracy on a dataset of 284,807 transactions. Preprocessed and normalized the data while handling class imbal…

From the performance of the random forest model, it looks to me like the model isn't working well for the most expensive properties. I was thinking maybe we could use over/undersampling to correct thi…

Add the ability for a node to scan more than one frequency. A 4-node timer can then be used as an 8-node timer at the expense of a loss of accuracy which is acceptable for practice sessions.

I am thinking of implementing an undersampling custom component for TFX, as described in this issue for TFX: https://github.com/tensorflow/tfx/issues/3831. This component may also include oversampling…

Thank you for all your hard work.
I've noticed that in your implementation of classifiers in `ClassificationEvaluator`, it seems that classifiers like `LogisticRegression` and `kNN` are [trained o…

With severely imbalanced classes, people often undersample the more frequent class or oversample the less frequent class (see https://www3.nd.edu/~dial/publications/hoens2013imbalanced.pdf). There are…

You are Undersampling the test data, in order to test the model in real world scenario you should test the model with data's real distribution.

### Problem
Minetest provides several default graphics and shader features that improve the game's look. However, these features reduce the performance and thus reduce the playable render distance.…

When using undersampling / bitmap zoom, the zoomed bitmap is created in memory, even if it's not displayed in full. That makes it impossible to create, for example, a 3000×3000 image with 10×10 unders…
