Paper Discussion: Attention is all you need
summary
Paper argues that replacing recurrence with self‑attention yields a faster, more scalable sequence model that still beats RNN/CNN baselines on translation and parsing. Key specifics: six encoder and six decoder layers, 512‑dim embeddings, and sine/cosine positional encodings produce parallelizable scaled dot‑product attention with multiheads. Training uses Adam with warmup learning rate, dropout and label smoothing; experiments on WMT English–German and English–French report the Transformer big model training in days on GPUs and achieving state‑of‑the‑art BLEU scores and improved generalization.
