Witryna9 kwi 2024 · Dealing with data imbalance in a regression model? I'm working on a regression model that predicts (x,y) coordinates of points on a 2-d plot. The pink points are my actuals. We see that there are chunks of my actuals plot that are intentionally void of data, but my model is predicting values there (my few example blue prediction points). Data imbalance is ubiquitous and inherent in the real world. Rather than preserving an ideal uniform distribution over each category, the data often exhibit skewed distributions with a long tail, where certain target values have significantly fewer observations. This phenomenon poses great challenges for … Zobacz więcej Yet, we note that, DIR brings new challenges distinct from its classification counterpart.
