cosine ≥ 0.65 · no typed edgeEntities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.
- Basic unit of LLM input/output: words, parts of words, punctuation marks, emojis
- Vector representations of individual tokens from genomic foundation models; the raw inputs to sequence pooling methods.
- A discrete token in the vocabulary that represents a visual operation (e.g., <|Line|>, <|Shape|>, <|Text|>), generated via next-token prediction within autoregressive sequences.
- The training objective of LLMs: predicting the most likely next token given context; formally P(w_{n+1}|w_1...w_n)
- Feature that fires on a specific token only within a specific surrounding context (e.g., 'the' in physics vs 'the' in mathematics)
- A possible circuit that triggers when activations deviate from expected values, hypothesized to underlie noticing injected thoughts.
- Baseline steering method that applies intervention at every token generation step, shown to degrade performance at high strengths
- An attention head that primarily attends to the immediately preceding token; key building block for induction heads via K-composition
