Learning Dynamic Network Using a Reuse Gate Function in Semi-Supervised Video Object Segmentation

CVPR 2021poster

Current state-of-the-art approaches for Semi-supervised Video Object Segmentation (Semi-VOS) propagates information from previous frames to generate segmentation mask for the current frame. This results in high-quality segmentation across challenging scenarios such as changes in appearance and occlu…

Mixed Precision Training

ICLR 2018poster

Increasing the size of a neural network typically improves accuracy but also increases the memory and compute requirements for training the model. We introduce methodology for training deep neural networks using half-precision floating point numbers, without losing model accuracy or having to modify…

Accelerating Deep Convolutional Networks using low-precision and sparsity

ICASSP 2017accepted

We explore techniques to significantly improve the compute efficiency and performance of Deep Convolution Networks without impacting their accuracy. To improve the compute efficiency, we focus on achieving high accuracy with extremely low-precision (2-bit) weight networks, and to accelerate the exec…
