How is the obama-0075.params file generated

[olivercox]

I've had a look at the char_lstm tutorial and notice a file named obama-0075.params that is included in the zip file download.

Could you explain how this file is generated or point me in the right direction?

Think I may have answered my own question, assuming I'm right in thinking that changing the num_epoch variable controls this.

# We will show a quick demo with only 1 epoch. In practice, we can set it to be 100
num_epoch = 75
# learning rate 
learning_rate = 0.01
...
model = mx.model.FeedForward(
    ctx=mx.cpu(0),
    symbol=symbol,
    num_epoch=num_epoch,
    learning_rate=learning_rate,
    momentum=0,
    wd=0.0001,
    initializer=mx.init.Xavier(factor_type="in", magnitude=2.34))

Could anyone explain the use of epoch in the FeedForward method?
