concept:positional-information-gradientPositional information gradient
Gradient that tells a cell its correct position; stress arises from deviation from this gradient.
Neighborhood — ranked by edge-count
Related by similarity (8)
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.
- The biological mechanism by which chemical gradients create developmental patterns; cited as insufficient to explain coherence of embryological unfolding as a whole
- The property that qualities vary slowly, subtly, gradually across the extent of each living thing; gradients arise as natural responses to changing circumstances and create field-like character that points toward and establishes centers
- Baseline method against which probe-based ranking is compared; more computationally expensive.
- Used for updating hidden state expectations; provides dynamical process theory testable against neuronal data
- Mechanism for encoding sequence order in transformers; paper argues these should reflect learned structural representations rather than fixed sines/cosines.
- Optimization technique that computes weight changes by following the gradient of an error function; contrasted with evolutionary stochastic search.
- When gradients of different tasks have negative cosine similarity, harming multi-task learning.
- Method for stabilising drifting recurrent position encodings by querying stored landmark memories to correct path-integrated position.
