Java Heap space error

Sir Please tell me when i am increase the size of file dataset which i want to use for training neural network. then i am facing the exception :

Try to Google Java OutOfMemory error.

thanks..

[AbhiMangal]

sir how can i reduce the time to train the neural network . when i use very big file to train the model?
please reply me as soon as possible.

[guerda]

Try increasing fast memory and add additional CPUs. This will increase performance of the training.

[AbhiMangal]

may i use for it multithreading.?

[guerda]

This word2vec implementation uses multi threading wherever possible. You can configure how many threads are used.

How large the file you are training on? I am facing the same issue. I think the iterator should help save a lot of memory, but not.
