Exploiting the Potential of Seq2Seq Models as Robust Few-Shot Learners

no code implementations27 Jul 2023 Jihyeon Lee, Dain Kim, Doohae Jung, Boseop Kim, Kyoung-Woon On

In-context learning, which offers substantial advantages over fine-tuning, is predominantly observed in decoder-only models, while encoder-decoder (i. e., seq2seq) models excel in methods that rely on weight updates.

Pushing the Accuracy-Group Robustness Frontier with Introspective Self-play

no code implementations11 Feb 2023 Jeremiah Zhe Liu, Krishnamurthy Dj Dvijotham, Jihyeon Lee, Quan Yuan, Martin Strobel, Balaji Lakshminarayanan, Deepak Ramachandran

Standard empirical risk minimization (ERM) training can produce deep neural network (DNN) models that are accurate on average but under-perform in under-represented population subgroups, especially when there are imbalanced group distributions in the long-tailed training data.

Dense but Efficient VideoQA for Intricate Compositional Reasoning

no code implementations19 Oct 2022 Jihyeon Lee, Wooyoung Kang, Eun-Sol Kim

It is well known that most of the conventional video question answering (VideoQA) datasets consist of easy questions requiring simple reasoning processes.

SustainBench: Benchmarks for Monitoring the Sustainable Development Goals with Machine Learning

1 code implementation8 Nov 2021 Christopher Yeh, Chenlin Meng, Sherrie Wang, Anne Driscoll, Erik Rozi, Patrick Liu, Jihyeon Lee, Marshall Burke, David B. Lobell, Stefano Ermon

Our goals for SustainBench are to (1) lower the barriers to entry for the machine learning community to contribute to measuring and achieving the SDGs; (2) provide standard benchmarks for evaluating machine learning models on tasks across a variety of SDGs; and (3) encourage the development of novel machine learning methods where improved model performance facilitates progress towards the SDGs.

BiaSwap: Removing dataset bias with bias-tailored swapping augmentation

no code implementations ICCV 2021 Eungyeup Kim, Jihyeon Lee, Jaegul Choo

Although previous approaches pre-define the type of dataset bias to prevent the network from learning it, recognizing the bias type in the real dataset is often prohibitive.

Learning Debiased Representation via Disentangled Feature Augmentation

1 code implementation NeurIPS 2021 Jungsoo Lee, Eungyeup Kim, Juyoung Lee, Jihyeon Lee, Jaegul Choo

To this end, our method learns the disentangled representation of (1) the intrinsic attributes (i. e., those inherently defining a certain class) and (2) bias attributes (i. e., peripheral attributes causing the bias), from a large number of bias-aligned samples, the bias attributes of which have strong correlation with the target variable.

Assessing Post-Disaster Damage from Satellite Imagery using Semi-Supervised Learning Techniques

no code implementations24 Nov 2020 Jihyeon Lee, Joseph Z. Xu, Kihyuk Sohn, Wenhan Lu, David Berthelot, Izzeddin Gur, Pranav Khaitan, Ke-Wei, Huang, Kyriacos Koupparis, Bernhard Kowatsch

To respond to disasters such as earthquakes, wildfires, and armed conflicts, humanitarian organizations require accurate and timely data in the form of damage assessments, which indicate what buildings and population centers have been most affected.

Predicting Livelihood Indicators from Community-Generated Street-Level Imagery

1 code implementation15 Jun 2020 Jihyeon Lee, Dylan Grosz, Burak Uzkent, Sicheng Zeng, Marshall Burke, David Lobell, Stefano Ermon

Major decisions from governments and other large organizations rely on measurements of the populace's well-being, but making such measurements at a broad scale is expensive and thus infrequent in much of the developing world.

A Free Lunch in Generating Datasets: Building a VQG and VQA System with Attention and Humans in the Loop

no code implementations30 Nov 2019 Jihyeon Lee, Sho Arora

By demonstrating how our system can collect large amounts of data at little to no cost, we envision similar systems being used to improve performance on other tasks in the future.
