Improve model accuracy for training and prediction

TensorFlow General Discussion
,
1

Hello everyone,

I am new with tensorflow: I have created a neural network model with 20 inputs 1 output and 256 samples. I got a training accuracy of 75% and prediction 69% (calculated with R2 method). Quite poor accuracy. Do you have any suggestion how to improve the accuracy of the model?

Many thanks in advance,

Improving Model Accuracy

  • Collect data: Increase the number of training examples.
  • Feature processing: Add more variables and better feature processing.
  • Model parameter tuning: Consider alternate values for the training parameters used by your learning algorithm.

Thanks for the help.
The dataset is defined and I cannot increase it. So unfortunatelly it is not an option.
Also the number of input variables is defined.
Could you please indicate which parameters to alternate (option3 of your reply)?

Thanks
