Researchers have developed a new hardware-oriented methodology to accelerate Bayesian inference on embedded GPUs, addressing the computational cost that typically hinders deployment on resource-constrained edge devices. The approach optimizes tensor contractions, a key bottleneck in variational message-passing algorithms, by restructuring memory layouts and employing sparse array representations. This optimization has been applied to algorithms for Hidden Markov Models, achieving speedups of up to 5x on an NVIDIA Jetson Orin AGX, with typical gains of 2-2.5x, while maintaining numerical accuracy.
