TJDR: A High-Quality Diabetic Retinopathy Pixel-Level Annotation Dataset

1 code implementation24 Dec 2023 Jingxin Mao, Xiaoyu Ma, Yanlong Bi, Rongqing Zhang

Diabetic retinopathy (DR), as a debilitating ocular complication, necessitates prompt intervention and treatment.

A phase transition for finding needles in nonlinear haystacks with LASSO artificial neural networks

1 code implementation21 Jan 2022 Xiaoyu Ma, Sylvain Sardy, Nick Hengartner, Nikolai Bobenko, Yen Ting Lin

To fit sparse linear associations, a LASSO sparsity inducing penalty with a single hyperparameter provably allows to recover the important features (needles) with high probability in certain regimes even if the sample size is smaller than the dimension of the input vector (haystack).

Mitigating Edge Machine Learning Inference Bottlenecks: An Empirical Study on Accelerating Google Edge Models

no code implementations1 Mar 2021 Amirali Boroumand, Saugata Ghose, Berkin Akin, Ravi Narayanaswami, Geraldo F. Oliveira, Xiaoyu Ma, Eric Shiu, Onur Mutlu

We comprehensively study the characteristics of each NN layer in all of the Google edge models, and find that these shortcomings arise from the one-size-fits-all approach of the accelerator, as there is a high amount of heterogeneity in key layer characteristics both across different models and across different layers in the same model.

Google Neural Network Models for Edge Devices: Analyzing and Mitigating Machine Learning Inference Bottlenecks

no code implementations29 Sep 2021 Amirali Boroumand, Saugata Ghose, Berkin Akin, Ravi Narayanaswami, Geraldo F. Oliveira, Xiaoyu Ma, Eric Shiu, Onur Mutlu

To understand how edge ML accelerators perform, we characterize the performance of a commercial Google Edge TPU, using 24 Google edge NN models (which span a wide range of NN model types) and analyzing each NN layer within each model.

Testing for context-dependent changes in neural encoding in naturalistic experiments

no code implementations17 Nov 2022 Yenho Chen, Carl W. Harris, Xiaoyu Ma, Zheng Li, Francisco Pereira, Charles Y. Zheng

We propose a decoding-based approach to detect context effects on neural codes in longitudinal neural recording data.

Learning to Influence Vehicles' Routing in Mixed-Autonomy Networks by Dynamically Controlling the Headway of Autonomous Cars

1 code implementation7 Mar 2023 Xiaoyu Ma, Negar Mehr

We train an RL policy that learns to regulate the headway of autonomous cars such that the total travel time in the network is minimized.

Flexible and efficient spatial extremes emulation via variational autoencoders

no code implementations16 Jul 2023 Likun Zhang, Xiaoyu Ma, Christopher K. Wikle, Raphaël Huser

Many real-world processes have complex tail dependence structures that cannot be characterized using classical Gaussian processes.
