Extended Kalman Filtering for Recursive Online Discrete-Time Inverse Optimal Control

no code implementations16 Mar 2024 Tian Zhao, Timothy L. Molloy

We formulate the discrete-time inverse optimal control problem of inferring unknown parameters in the objective function of an optimal control problem from measurements of optimal states and controls as a nonlinear filtering problem.

Transfer Learning for Microstructure Segmentation with CS-UNet: A Hybrid Algorithm with Transformer and CNN Encoders

1 code implementation26 Aug 2023 Khaled Alrfou, Tian Zhao, Amir Kordijazi

Our result partially confirms the NASA study that the segmentation performance of out-of-distribution images (taken under different imaging and sample conditions) is significantly improved when pre-training on microscopy images.

Efficient Memory Partitioning in Software Defined Hardware

no code implementations2 Feb 2022 Matthew Feldman, Tian Zhao, Kunle Olukotun

As programmers turn to software-defined hardware (SDH) to maintain a high level of productivity while programming hardware to run complex algorithms, heavy-lifting must be done by the compiler to automatically partition on-chip arrays.

Serving Recurrent Neural Networks Efficiently with a Spatial Accelerator

no code implementations26 Sep 2019 Tian Zhao, Yaqi Zhang, Kunle Olukotun

Recurrent Neural Network (RNN) applications form a major class of AI-powered, low-latency data center workloads.

Analysis of DAWNBench, a Time-to-Accuracy Machine Learning Performance Benchmark

no code implementations4 Jun 2018 Cody Coleman, Daniel Kang, Deepak Narayanan, Luigi Nardi, Tian Zhao, Jian Zhang, Peter Bailis, Kunle Olukotun, Chris Re, Matei Zaharia

In this work, we analyze the entries from DAWNBench, which received optimized submissions from multiple industrial groups, to investigate the behavior of TTA as a metric as well as trends in the best-performing entries.

DeepDSL: A Compilation-based Domain-Specific Language for Deep Learning

1 code implementation9 Jan 2017 Tian Zhao, Xiaobing Huang, Yu Cao

In this paper, we present DeepDSL, a domain specific language (DSL) embedded in Scala, that compiles deep networks written in DeepDSL to Java source code.
