WebI am implementing a Language Model based on a Deep Learning architecture (RNN+Softmax). The cost function I am using is the cross-entropy between the vector of probabilities at the softmax layer and the one-hot vector of the target word to predict. For every epoch, I am computing the perplexity as: where is the number of batches per-epoch.
WebThese perplexities are equal or better than Recurrent Neural Network Regularization (Zaremba et al. 2014) and are similar to Using the Output Embedding to Improve Language Models (Press & Wolf 2016 and Tying Word Vectors and Word Classifiers: A Loss Framework for Language Modeling (Inan et al. 2016), though both of these papers have … WebPerplexity – measuring the quality of the text result It is not just enough to produce text; we also need a way to measure the quality of the produced text.
