Evoke: Evoking Critical Thinking Abilities in LLMs via Reviewer-Author Prompt Editing

no code implementations20 Oct 2023 Xinyu Hu, Pengfei Tang, Simiao Zuo, Zihan Wang, Bowen Song, Qiang Lou, Jian Jiao, Denis Charles

In Evoke, there are two instances of a same LLM: one as a reviewer (LLM-Reviewer), it scores the current prompt; the other as an author (LLM-Author), it edits the prompt by considering the edit history and the reviewer's feedback.

TEDL: A Two-stage Evidential Deep Learning Method for Classification Uncertainty Quantification

no code implementations12 Sep 2022 Xue Li, Wei Shen, Denis Charles

In this paper, we propose TEDL, a two-stage learning approach to quantify uncertainty for deep learning models in classification tasks, inspired by our findings in experimenting with Evidential Deep Learning (EDL) method, a recently proposed uncertainty quantification approach based on the Dempster-Shafer theory.

Masked LARk: Masked Learning, Aggregation and Reporting worKflow

1 code implementation27 Oct 2021 Joseph J. Pfeiffer III, Denis Charles, Davis Gilton, Young Hun Jung, Mehul Parsana, Erik Anderson

We introduce a secure multi-party compute (MPC) protocol that utilizes "helper" parties to train models, so that once data leaves the browser, no downstream system can individually construct a complete picture of the user activity.

Causal Transfer Random Forest: Combining Logged Data and Randomized Experiments for Robust Prediction

no code implementations17 Oct 2020 Shuxi Zeng, Murat Ali Bayir, Joesph J. Pfeiffer III, Denis Charles, Emre Kiciman

We describe a causal transfer random forest (CTRF) that combines existing training data with a small amount of data from a randomized experiment to train a model which is robust to the feature shifts and therefore transfers to a new targeting distribution.

Data Transformation Insights in Self-supervision with Clustering Tasks

no code implementations18 Feb 2020 Abhimanu Kumar, Aniket Anand Deshmukh, Urun Dogan, Denis Charles, Eren Manavoglu

We show faster convergence rate with valid transformations for convex as well as certain family of non-convex objectives along with the proof of convergence to the original set of optima.

A Unified Batch Online Learning Framework for Click Prediction

1 code implementation12 Sep 2018 Rishabh Iyer, Nimit Acharya, Tanuja Bompada, Denis Charles, Eren Manavoglu

Through extensive experiments, we demonstrate the utility of of our OL framework; how the two OL schemes relate to each other and how they trade-off between the new and historical data.

Modeling and Simultaneously Removing Bias via Adversarial Neural Networks

no code implementations18 Apr 2018 John Moore, Joel Pfeiffer, Kai Wei, Rishabh Iyer, Denis Charles, Ran Gilad-Bachrach, Levi Boyles, Eren Manavoglu

In real world systems, the predictions of deployed Machine Learned models affect the training data available to build subsequent models.
