Monty Hall and Optimized Conformal Prediction to Improve Decision-Making with LLMs

no code implementations31 Dec 2024 Harit Vishwakarma, Alan Mishler, Thomas Cook, Niccolò Dalmasso, Natraj Raman, Sumitra Ganesh

To mitigate these risks, recent works have used conformal prediction (CP), a model-agnostic framework for distribution-free uncertainty quantification.

Global Graph Counterfactual Explanation: A Subgraph Mapping Approach

no code implementations25 Oct 2024 Yinhan He, Wendy Zheng, Yaochen Zhu, Jing Ma, Saumitra Mishra, Natraj Raman, Ninghao Liu, Jundong Li

Methodologically, we design a significant subgraph generator and a counterfactual subgraph autoencoder in our GlobalGCE, where the subgraphs and the rules can be effectively generated.

Characterizing Multimodal Long-form Summarization: A Case Study on Financial Reports

no code implementations9 Apr 2024 Tianyu Cao, Natraj Raman, Danial Dervovic, Chenhao Tan

In this paper, we use financial report summarization as a case study because financial reports are not only long but also use numbers and tables extensively.

Synthetic Document Generator for Annotation-free Layout Recognition

no code implementations11 Nov 2021 Natraj Raman, Sameena Shah, Manuela Veloso

Analyzing the layout of a document to identify headers, sections, tables, figures etc.

Robust Document Representations using Latent Topics and Metadata

no code implementations23 Oct 2020 Natraj Raman, Armineh Nourbakhsh, Sameena Shah, Manuela Veloso

Task specific fine-tuning of a pre-trained neural language model using a custom softmax output layer is the de facto approach of late when dealing with document classification problems.
