Career
Shrivastava earned computer-science and master’s degrees at the University of Washington in 2018 and 2019. At Meta, his work spanned language AI for AR devices, model inference and multimodal pretraining. In November 2024 he and Armen Aghajanyan left FAIR to build Perceptron, focusing on models that process information from the physical world.[2][3][4]
Contributions
Use one model to draft and verify tokens
Shrivastava is an equal-contribution author of LayerSkip. The training method combines layer dropout with an early-exit loss so earlier layers can make useful token predictions. At inference time, those layers draft tokens and later layers verify them. This self-speculative approach reuses the same model’s computation and activations, avoiding the need for a separate draft model.[5]
Generate structured meaning more efficiently
His first-listed-author work on span-pointer networks addresses task-oriented semantic parsing. Instead of generating every output word in sequence, the model predicts a structured representation using pointers to spans of the input. The paper studies the speed and accuracy of this non-autoregressive approach on semantic-parsing benchmarks.[7]
