QUESTION
I am trying to train a linear regression model in Tensorflow using some generated data. The model seems to learn the slope of the line, but is unable to learn the bias.
I have tried changing the no. of epochs, the weight(slope) and the biases, but every time , the learnt bias by the model comes out to be zero. I don't know where I am going wrong and some help would be appreciated.
Here is the code.
...ANSWER
Answered 2017-Jun-30 at 10:09The main problem is that you are feeding just one sample at a time to the model. This makes your optimizer very inestable, that's why you have to use such a small learning rate. I will suggest you to feed more samples in each step.
If you insist in feeding one sample at a time, maybe you should consider using an optimizer with momentum, like tf.train.AdamOptimizer(learning_rate)
. This way you can increase the learning rate and reach convergence.
