Researchers have developed a novel photonic processor that utilizes temporal speckle to represent probabilistic weights for uncertainty-aware artificial intelligence. This approach encodes mean and variance directly into the fluctuations of broadband light, bypassing the computational demands of traditional Bayesian neural networks. The system achieves ultrafast probabilistic convolutions, enabling simultaneous classification and out-of-distribution detection in hybrid Bayesian neural networks, as demonstrated by its ability to classify blood-cell images while identifying unfamiliar cell types.
