A Graph-Based Framework for Structured Prediction Tasks in Sanskrit

no code implementations CL (ACL) 2020 Amrith Krishna, Bishal Santra, Ashim Gupta, Pavankumar Satuluri, Pawan Goyal

Ours is a search-based structured prediction framework, which expects a graph as input, where relevant linguistic information is encoded in the nodes, and the edges are then used to indicate the association between these nodes.

Whispers of Doubt Amidst Echoes of Triumph in NLP Robustness

1 code implementation16 Nov 2023 Ashim Gupta, Rishanth Rajendhran, Nathan Stringham, Vivek Srikumar, Ana Marasović

Do larger and more performant models resolve NLP's longstanding robustness issues?

Adversarial Clean Label Backdoor Attacks and Defenses on Text Classification Systems

no code implementations31 May 2023 Ashim Gupta, Amrith Krishna

Clean-label (CL) attack is a form of data poisoning attack where an adversary modifies only the textual input of the training data, without requiring access to the labeling function.

Don't Retrain, Just Rewrite: Countering Adversarial Perturbations by Rewriting Text

no code implementations25 May 2023 Ashim Gupta, Carter Wood Blum, Temma Choji, Yingjie Fei, Shalin Shah, Alakananda Vempala, Vivek Srikumar

For example, on sentiment classification using the SST-2 dataset, our method improves the adversarial accuracy over the best existing defense approach by more than 4% with a smaller decrease in task accuracy (0. 5% vs 2. 5%).

Sāmayik: A Benchmark and Dataset for English-Sanskrit Translation

1 code implementation23 May 2023 Ayush Maheshwari, Ashim Gupta, Amrith Krishna, Atul Kumar Singh, Ganesh Ramakrishnan, G. Anil Kumar, Jitin Singla

Translation models trained on our dataset demonstrate statistically significant improvements when translating out-of-domain contemporary corpora, outperforming models trained on older classical-era poetry datasets.

BERT & Family Eat Word Salad: Experiments with Text Understanding

1 code implementation10 Jan 2021 Ashim Gupta, Giorgi Kvernadze, Vivek Srikumar

In this paper, we study the response of large models from the BERT family to incoherent inputs that should confuse any model that claims to understand natural language.

Evaluating Neural Morphological Taggers for Sanskrit

1 code implementation WS 2020 Ashim Gupta, Amrith Krishna, Pawan Goyal, Oliver Hellwig

Neural sequence labelling approaches have achieved state of the art results in morphological tagging.

Neural Approaches for Data Driven Dependency Parsing in Sanskrit

no code implementations17 Apr 2020 Amrith Krishna, Ashim Gupta, Deepak Garasangi, Jivnesh Sandhan, Pavankumar Satuluri, Pawan Goyal

We compare the performance of each of the models in a low-resource setting, with 1, 500 sentences for training.

An LSTM-CRF Based Approach to Token-Level Metaphor Detection

no code implementations WS 2018 Malay Pramanick, Ashim Gupta, Pabitra Mitra

In this paper, we propose a method for detection of metaphors at the token level using a hybrid model of Bidirectional-LSTM and CRF.
