From text to representations

Understand why words become vectors without equating a vector with human meaning.

Definition

An embedding table maps token identifiers to vectors. Subsequent layers transform and combine them with context. The representation of “bank” can therefore depend on surrounding words and the learned objective.

Equation

xᵢ = E[tokenᵢ]; hᵢ = fθ(x₁, …, xₙ)ᵢ

E is the embedding table; fθ transforms inputs into contextual representations h. Specify the layer and metric before comparing vectors.

Assumptions and notation

E is the embedding table; fθ transforms inputs into contextual representations h. Specify the layer and metric before comparing vectors.

Limits of interpretation

Vector proximity depends on the representation and metric. It may help retrieve documents without proving equivalent meaning or human understanding.
