Neural Slot Interpreters: Grounding Object Semantics in Emergent Slot Representations

no code implementations2 Feb 2024 Bhishma Dedhia, Niraj K. Jha

Finally, we formulate the NSI program generator model to use the dense associations inferred from the alignment model to generate object-centric programs from slots.

Zero-TPrune: Zero-Shot Token Pruning through Leveraging of the Attention Graph in Pre-Trained Transformers

no code implementations27 May 2023 Hongjie Wang, Bhishma Dedhia, Niraj K. Jha

Deployment of Transformer models on edge devices is becoming increasingly challenging due to the exponentially growing inference cost that scales quadratically with the number of tokens in the input sequence.

SCouT: Synthetic Counterfactuals via Spatiotemporal Transformers for Actionable Healthcare

no code implementations9 Jul 2022 Bhishma Dedhia, Roshini Balasubramanian, Niraj K. Jha

The Synthetic Control method has pioneered a class of powerful data-driven techniques to estimate the counterfactual reality of a unit from donor units.

FlexiBERT: Are Current Transformer Architectures too Homogeneous and Rigid?

no code implementations23 May 2022 Shikhar Tuli, Bhishma Dedhia, Shreshth Tuli, Niraj K. Jha

We also propose a novel NAS policy, called BOSHNAS, that leverages this new scheme, Bayesian modeling, and second-order optimization, to quickly train and use a neural surrogate model to converge to the optimal architecture.

Lower Bounds for Policy Iteration on Multi-action MDPs

no code implementations16 Sep 2020 Kumar Ashutosh, Sarthak Consul, Bhishma Dedhia, Parthasarathi Khirwadkar, Sahil Shah, Shivaram Kalyanakrishnan

An important theoretical question is how many iterations a specified PI variant will take to terminate as a function of the number of states $n$ and the number of actions $k$ in the input MDP.

Analysis of Lower Bounds for Simple Policy Iteration

no code implementations28 Nov 2019 Sarthak Consul, Bhishma Dedhia, Kumar Ashutosh, Parthasarathi Khirwadkar

We generalize the previous result and prove a novel exponential lower bound on the number of iterations taken by policy iteration for $N-$state, $k-$action MDPs.
