r/MachineLearning - [D] Are small transformers better than small LSTMs?

#artificialintelligence

Transformers are currently beating the state of the art on different NLP tasks. Something I noticed is that in all of the papers, the models are massive with maybe 20 layers and 100s of millions of parameters. Of course, using larger models is a general trend in NLP but it begs the question if small transformers are any good. I recently had to train a sequence to sequence model from scratch and I was unable to get better results with a transformer than with LSTMs. I am wondering if someone here has had similar experiences or knows of any papers on this topic.
