UnverifiedOffline file transcription can use bidirectional attention mechanisms to integrate information from both preceding and following context, and can perform multiple rounds of decoding and reranking to improve accuracy.72% similarVerifiedRelative positional encoding schemes such as RoPE (Rotary Position Embedding) and ALiBi enable models to handle text sequences far longer than those seen during training.71% similarUnverifiedCurrent mainstream large language models generally adopt the Transformer architecture, whose self-attention mechanism has a computational complexity that grows quadratically with sequence length (O(n²)) when processing long contexts.71% similarUnverifiedEmbedding models map text to high-dimensional dense vectors (typically 768 to 3072 dimensions), and ANN algorithms (such as HNSW and IVF-PQ) reduce retrieval complexity from O(n) to approximately O(log n).69% similarUnverifiedThe summarization capability of large language models is essentially the process of identifying key semantic nodes in text through the attention mechanism, compressing long documents into short texts that retain the core arguments.69% similar
