Getting very bad prediction with the KerasRegressor

[shasha...@gmail.com]

I used KerasRegressor on a dummy dataset and tried to predict the training values itself. It is giving me an output far from satisfactory. The training data is not random at all. Could anyone help me out? Link to all the data (and details):

The actual values should be: [3 4 5 6 7]

Predicted values are: [0.001 0.001 0.001 0.001 0.001]
