NN model-The predicted range seems limited
As the plot,HDD_OSA range is from 30 to 100,but the predicted OSA range is from 65 to 75.
How to understand this ? how to improve the predicted range?
Please help,thanks!

AnalyticsRe: NN model-The predicted range seems limitedHi
The problem with predictive models is that your forecast data distribution is centered around 65-75. And the fitting effect of the model is not ideal. When your forecast results are centered around 65-75, but the data range for the actual results is 35-95. So the residual is too large and the R-squared is very low. Can you provide the data source if it is convenient? Otherwise, it's hard to say what the problem is.
Re: NN model-The predicted range seems limitedYes,the model is poor ,I pay more attention to the predicted range.
Try use Python,change the activation function from tanh to relu, seems the predicted range become better.
