In recent gensim versions you can load a subset starting from the front of the file using the optional limit parameter to load_word2vec_format(). (The GoogleNews vectors seem to be in roughly most- to least- frequent order, so the first N are usually the N-sized subset you’d want. So use limit=500000 to get the most-frequent 500,000 … Read more
You didn’t say what architecture you’re talking about. Since you said you want to classify images, I’m assuming it’s a partly convolutional, partly fully connected network like AlexNet, GoogLeNet, etc. In general, the answer to your question depends on the network type you are working with. If, for example, your network only contains convolutional units … Read more
I have stumbled upon this problem too and below is what I figured out. When training RNN (LSTM or GRU or vanilla-RNN), it is difficult to batch the variable length sequences. For example: if the length of sequences in a size 8 batch is [4,6,8,5,4,3,7,8], you will pad all the sequences and that will result … Read more
