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

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

We propose a computational framework for characterizing multimodal long-form summarization and investigate the behavior of Claude 2. 0/2. 1, GPT-4/3. 5, and Command.

Bounding the Excess Risk for Linear Models Trained on Marginal-Preserving, Differentially-Private, Synthetic Data

no code implementations6 Feb 2024 Yvonne Zhou, Mingyu Liang, Ivan Brugere, Dana Dachman-Soled, Danial Dervovic, Antigoni Polychroniadou, Min Wu

The growing use of machine learning (ML) has raised concerns that an ML model may reveal private information about an individual who has contributed to the training dataset.

A Canonical Data Transformation for Achieving Inter- and Within-group Fairness

no code implementations23 Oct 2023 Zachary McBride Lazri, Ivan Brugere, Xin Tian, Dana Dachman-Soled, Antigoni Polychroniadou, Danial Dervovic, Min Wu

The mapping is constructed to preserve the relative relationship between the scores obtained from the unprocessed feature vectors of individuals from the same demographic group, guaranteeing within-group fairness.

On the Connection between Game-Theoretic Feature Attributions and Counterfactual Explanations

no code implementations13 Jul 2023 Emanuele Albini, Shubham Sharma, Saumitra Mishra, Danial Dervovic, Daniele Magazzeni

Explainable Artificial Intelligence (XAI) has received widespread interest in recent years, and two of the most popular types of explanations are feature attributions, and counterfactual explanations.

Rethinking Log Odds: Linear Probability Modelling and Expert Advice in Interpretable Machine Learning

no code implementations11 Nov 2022 Danial Dervovic, Nicolas Marchesotti, Freddy Lecue, Daniele Magazzeni

We introduce a family of interpretable machine learning models, with two broad additions: Linearised Additive Models (LAMs) which replace the ubiquitous logistic link function in General Additive Models (GAMs); and SubscaleHedge, an expert advice algorithm for combining base models trained on subsets of features called subscales.

Counterfactual Shapley Additive Explanations

2 code implementations27 Oct 2021 Emanuele Albini, Jason Long, Danial Dervovic, Daniele Magazzeni

Feature attributions are a common paradigm for model explanations due to their simplicity in assigning a single numeric score for each input feature to a model.
