Softmax action policy

Read the equation

Convert action values into a distribution over actions by applying softmax across the available action set. Actions with larger values receive larger probability, while finite values keep every available action at positive probability.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read π(a|s) as the quantity being defined or updated by this relation.

2. Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

• The action axis and temperature are not printed. An implementation needs a defined action set and a numerically stable normalization.

Original context

π(a|s) = softmax(Q(s,a))
