Results for "vector search"

Choosing step size along gradient direction.

Search algorithm for generation that keeps top-k partial sequences; can improve likelihood but reduce diversity.

Retrieval based on embedding similarity rather than keyword overlap, capturing paraphrases and related concepts.

A datastore optimized for similarity search over embeddings, enabling semantic retrieval at scale.

Directly optimizing control policies.

Set of vectors closed under addition and scalar multiplication.

Optimal pathfinding algorithm.

Measure of vector magnitude; used in regularization and optimization.

Mathematical foundation for ML involving vector spaces, matrices, and linear transformations.

Vector whose direction remains unchanged under linear transformation.

Raw model outputs before converting to probabilities; manipulated during decoding and calibration.

Configuration choices not learned directly (or not typically learned) that govern training or architecture.

Methods for breaking goals into steps; can be classical (A*, STRIPS) or LLM-driven with tool calls.

A continuous vector encoding of an item (word, image, user) such that semantic similarity corresponds to geometric closeness.

Converts logits to probabilities by exponentiation and normalization; common in classification and LMs.

Direction of steepest ascent of a function.

Architecture that retrieves relevant documents (e.g., from a vector DB) and conditions generation on them to reduce hallucinations.

Mechanisms for retaining context across turns/sessions: scratchpads, vector memories, structured stores.

Optimal estimator for linear dynamic systems.

Vectors with zero inner product; implies independence.

Matrix of first-order derivatives for vector-valued functions.

Number of steps considered in planning.

Agent reasoning about future outcomes.

Restricting updates to safe regions.

Lowest possible loss.

RL using learned or known environment models.

Computing collision-free trajectories.

Finding routes from start to goal.

Sampling-based motion planner.

Imagined future trajectories.
