Understanding Positional Encoding in Transformers
Websuch as GPT-3, typically require some form of positional encoding, such as positional em-beddings. However, we show that LMs with-out any explicit positional encoding are still competitive with standard models, and that this phenomenon is robust across different datasets, model sizes, and sequence lengths.

WebJan 8, 2024 · Такой способ токенизации называется BPE (Byte Pair Encoding). Но даже это иногда не самый оптимальный выбор. Чтобы сжать словарь ещё сильнее для обучения GPT OpenAI использовали byte-level BPE токенизацию. WebFeb 1, 2024 · Results of the study show that language models still perform similarly to standard models, even without explicit positional encoding. A joint study, led by researchers from Tel-Aviv University ... such as GPT-3 [1], are widely used in many Natural Language Processing applications as an efficient tool for modeling language. By design, … WebGPT is a model with absolute position embeddings so it’s usually advised to pad the inputs on the right rather than the left.
