How to train neural word embeddings? So I am new to Deep Learning and NLP. I have read several blog posts on medium, towardsdatascience and papers where they talk about pre-training the word embeddings in an unsupervised fashion and then use them in supervised DNN. But recently I read a blog post which suggested that training the word embeddings while training the neural network gives better results. This is the other link.
So my question is which one should I follow?
Some YouTube videos that I referred:

Deep Learning for NLP without Magic Part 1, 2 and 3
There is one answer to know: try both methods and take the one that gives the best result. I would say that in general pre-trained embeddings usually gives better results. You can also start with pre-treained embeddings as initial conditions and let the embeddings train maybe with a smaller learning rate.

In any case, the current state of the art for text classification is ULMFIT (https://arxiv.org/abs/1801.06146), which actually doesn't do any of this. It pre-trains embedding and RNN with a language model in the wikipedia and in the target text and then fine tunes the whole model with the target text.
