downsampled
Data points decreased
Downsampled describes data that has been reduced by selecting fewer samples from the original.
In audio and image processing, downsampling lowers resolution or quality to reduce file size: The downsampled image looked grainy on the large screen.
In statistics and machine learning, it means reducing a dataset by taking a subset: We downsampled the majority class to balance the training data.
