Extending the WILDS Benchmark for Unsupervised Adaptation

1 code implementation ICLR 2022 Shiori Sagawa, Pang Wei Koh, Tony Lee, Irena Gao, Sang Michael Xie, Kendrick Shen, Ananya Kumar, Weihua Hu, Michihiro Yasunaga, Henrik Marklund, Sara Beery, Etienne David, Ian Stavness, Wei Guo, Jure Leskovec, Kate Saenko, Tatsunori Hashimoto, Sergey Levine, Chelsea Finn, Percy Liang

Unlabeled data can be a powerful point of leverage for mitigating these distribution shifts, as it is frequently much more available than labeled data and can often be obtained from distributions beyond the source distribution as well.

Unsupervised Domain Adaptation For Plant Organ Counting

2 code implementations2 Sep 2020 Tewodros Ayalew, Jordan Ubbens, Ian Stavness

Supervised learning is often used to count objects in images, but for counting small, densely located objects, the required image annotations are burdensome to collect.

AutoCount: Unsupervised Segmentation and Counting of Organs in Field Images

no code implementations17 Jul 2020 Jordan Ubbens, Tewodros Ayalew, Steve Shirtliffe, Anique Josuttes, Curtis Pozniak, Ian Stavness

Counting plant organs such as heads or tassels from outdoor imagery is a popular benchmark computer vision task in plant phenotyping, which has been previously investigated in the literature using state-of-the-art supervised deep learning techniques.

Sparseout: Controlling Sparsity in Deep Networks

1 code implementation17 Apr 2019 Najeeb Khan, Ian Stavness

We found that sparsity of the activations is favorable for language modelling performance while image classification benefits from denser activations.

Global Sum Pooling: A Generalization Trick for Object Counting with Small Datasets of Large Images

no code implementations28 May 2018 Shubhra Aich, Ian Stavness

This generalization capability allows GSP to avoid both patchwise cancellation and overfitting by training on small patches and inference on full-resolution images as a whole.

Semantic Binary Segmentation using Convolutional Networks without Decoders

1 code implementation1 May 2018 Shubhra Aich, William van der Kamp, Ian Stavness

In this paper, we propose an efficient architecture for semantic image segmentation using the depth-to-space (D2S) operation.

Bridgeout: stochastic bridge regularization for deep neural networks

no code implementations21 Apr 2018 Najeeb Khan, Jawad Shah, Ian Stavness

Stochastic methods such as Dropout and Shakeout, in expectation, are equivalent to imposing a ridge and elastic-net penalty on the model parameters, respectively.

Improving Object Counting with Heatmap Regulation

2 code implementations14 Mar 2018 Shubhra Aich, Ian Stavness

Adding HR to a simple VGG front-end improves performance on all these benchmarks compared to a simple one-look baseline model and results in state-of-the-art performance for car counting.
