VayuAnukulani: Adaptive Memory Networks for Air Pollution Forecasting

no code implementations8 Apr 2019 Divyam Madaan, Radhika Dua, Prerana Mukherjee, Brejesh lall

Extensive experiments on data sources obtained in Delhi demonstrate that the proposed adaptive attention based Bidirectional LSTM Network outperforms several baselines for classification and regression models.

Beyond VQA: Generating Multi-word Answer and Rationale to Visual Questions

no code implementations24 Oct 2020 Radhika Dua, Sai Srinivas Kancheti, Vineeth N Balasubramanian

To take this a step forward, we introduce a new task: ViQAR (Visual Question Answering and Reasoning), wherein a model must generate the complete answer and a rationale that seeks to justify the generated answer.

Natural Attribute-based Shift Detection

no code implementations18 Oct 2021 Jeonghoon Park, Jimin Hong, Radhika Dua, Daehoon Gwak, Yixuan Li, Jaegul Choo, Edward Choi

Despite the impressive performance of deep networks in vision, language, and healthcare, unpredictable behaviors on samples from the distribution different than the training distribution cause severe problems in deployment.

Attribute Out of Distribution (OOD) Detection

Towards the Practical Utility of Federated Learning in the Medical Domain

1 code implementation7 Jul 2022 Seongjun Yang, Hyeonji Hwang, Daeyoung Kim, Radhika Dua, Jong-Yeup Kim, Eunho Yang, Edward Choi

We evaluate six FL algorithms designed for addressing data heterogeneity among clients, and a hybrid algorithm combining the strengths of two representative FL algorithms.

Federated Learning

Task Agnostic and Post-hoc Unseen Distribution Detection

no code implementations26 Jul 2022 Radhika Dua, Seongjun Yang, Yixuan Li, Edward Choi

Despite the recent advances in out-of-distribution(OOD) detection, anomaly detection, and uncertainty estimation tasks, there do not exist a task-agnostic and post-hoc approach.

Anomaly Detection Out of Distribution (OOD) Detection

Automatic Detection of Noisy Electrocardiogram Signals without Explicit Noise Labels

no code implementations8 Aug 2022 Radhika Dua, Jiyoung Lee, Joon-Myoung Kwon, Edward Choi

Automatic deep learning-based examination of ECG signals can lead to inaccurate diagnosis, and manual analysis involves rejection of noisy ECG samples by clinicians, which might cost extra time.

Reweighting Strategy based on Synthetic Data Identification for Sentence Similarity

1 code implementation COLING 2022 Taehee Kim, ChaeHun Park, Jimin Hong, Radhika Dua, Edward Choi, Jaegul Choo

To analyze this, we first train a classifier that identifies machine-written sentences, and observe that the linguistic features of the sentences identified as written by a machine are significantly different from those of human-written sentences.
