SocialGenPod: Privacy-Friendly Generative AI Social Web Applications with Decentralised Personal Data Stores

1 code implementation15 Mar 2024 Vidminas Vizgirda, Rui Zhao, Naman Goel

Unlike centralised Web and data architectures that keep user data tied to application and service providers, we show how one can use Solid -- a decentralised Web specification -- to decouple user data from generative AI applications.

FairTargetSim: An Interactive Simulator for Understanding and Explaining the Fairness Effects of Target Variable Definition

no code implementations9 Mar 2024 Dalia Gala, Milo Phillips-Brown, Naman Goel, Carinal Prunkl, Laura Alvarez Jubete, Medb Corcoran, Ray Eitel-Porter

Machine learning requires defining one's target variable for predictions or decisions, a process that can have profound implications on fairness: biases are often encoded in target variable definition itself, before any data collection or training.

On The Truthfulness of 'Surprisingly Likely' Responses of Large Language Models

no code implementations13 Nov 2023 Naman Goel

The surprisingly likely criterion in the seminal work of Prelec (the Bayesian Truth Serum) guarantees truthfulness in a game-theoretic multi-agent setting, by rewarding rational agents to maximise the expected information gain with their answers w. r. t.

Decentralised, Scalable and Privacy-Preserving Synthetic Data Generation

no code implementations30 Oct 2023 Vishal Ramesh, Rui Zhao, Naman Goel

Synthetic data is emerging as a promising way to harness the value of data, while reducing privacy risks.

Human-Guided Fair Classification for Natural Language Processing

1 code implementation20 Dec 2022 Florian E. Dorner, Momchil Peychev, Nikola Konstantinov, Naman Goel, Elliott Ash, Martin Vechev

While existing research has started to address this gap, current methods are based on hardcoded word replacements, resulting in specifications with limited expressivity or ones that fail to fully align with human intuition (e. g., in cases of asymmetric counterfactuals).

The Importance of Modeling Data Missingness in Algorithmic Fairness: A Causal Perspective

no code implementations21 Dec 2020 Naman Goel, Alfonso Amayuelas, Amit Deshpande, Amit Sharma

For example, in multi-stage settings where decisions are made in multiple screening rounds, we use our framework to derive the minimal distributions required to design a fair algorithm.

Infochain: A Decentralized, Trustless and Transparent Oracle on Blockchain

no code implementations27 Aug 2019 Naman Goel, Cyril van Schreven, Aris Filos-Ratsikas, Boi Faltings

For the first time, we show how to implement a trustless and transparent oracle in Ethereum.

Crowdsourcing with Fairness, Diversity and Budget Constraints

no code implementations31 Oct 2018 Naman Goel, Boi Faltings

Recent studies have shown that the labels collected from crowdworkers can be discriminatory with respect to sensitive attributes such as gender and race.

Deep Bayesian Trust : A Dominant and Fair Incentive Mechanism for Crowd

no code implementations16 Apr 2018 Naman Goel, Boi Faltings

We propose a novel mechanism that assigns gold tasks to only a few workers and exploits transitivity to derive accuracy of the rest of the workers from their peers' accuracy.

Parameter Database : Data-centric Synchronization for Scalable Machine Learning

no code implementations4 Aug 2015 Naman Goel, Divyakant Agrawal, Sanjay Chawla, Ahmed Elmagarmid

We propose a new data-centric synchronization framework for carrying out of machine learning (ML) tasks in a distributed environment.
