New Delta-AI algorithm speeds up inference in sparse graphical models

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Delta-AI, a novel algorithm designed for amortized inference in sparse probabilistic graphical models (PGMs). This method leverages the sparsity of PGMs to enable local credit assignment within an agent's policy learning objective. By framing variable sampling as a sequence of actions, Delta-AI facilitates off-policy training without requiring the instantiation of all random variables for each parameter update, significantly accelerating the training process.

    Delta-AI: Local objectives for amortized inference in sparse graphical models

    arXiv:2310.02423v3 Announce Type: replace Abstract: We present a new algorithm for amortized inference in sparse probabilistic graphical models (PGMs), which we call $\Delta$-amortized inference ($\Delta$-AI). Our approach is based on the observation that when the sampling of var…
