Code Monitor Red Teaming for Public-Test-Passing Code

Junchi Liao, Jiawen Deng, Fuji Ren

Visible tests are a common gate for LLM-generated code, but passing them does not certify specification correctness. We study a deployment-like monitoring problem: after code has p…

Controlling the Extraction of Memorized Data from Large Language Models via Prompt-Tuning

Mustafa Safa Ozdayi, Charith Peris, Jack FitzGerald +5

Large Language Models (LLMs) are known to memorize significant portions of their training data. Parts of this memorized content have been shown to be extractable by simply querying…

Differentially Private Decoding in Large Language Models

Jimit Majmudar, Christophe Dupuy, Charith Peris +3

Recent large-scale natural language processing (NLP) systems use a pre-trained Large Language Model (LLM) on massive and diverse corpora as a headstart. In practice, the pre-traine…

Canary Extraction in Natural Language Understanding Models

Rahil Parikh, Christophe Dupuy, Rahul Gupta

Natural Language Understanding (NLU) models can be trained on sensitive information such as phone numbers, zip-codes etc. Recent literature has focused on Model Inversion Attacks (…

Learnings from Federated Learning in the Real world

Christophe Dupuy, Tanya G. Roosta, Leo Long +3

Federated Learning (FL) applied to real world data may suffer from several idiosyncrasies. One such idiosyncrasy is the data distribution across devices. Data across devices could…

An Efficient DP-SGD Mechanism for Large Scale NLP Models

Christophe Dupuy, Radhika Arava, Rahul Gupta +1

Recent advances in deep learning have drastically improved performance on many Natural Language Understanding (NLU) tasks. However, the data used to train NLU models may contain pr…

Self-Attention Gazetteer Embeddings for Named-Entity Recognition

Stanislav Peshterliev, Christophe Dupuy, Imre Kiss

Recent attempts to ingest external knowledge into neural models for named-entity recognition (NER) have exhibited mixed results. In this work, we present GazSelfAttn, a novel gazet…

Learning Determinantal Point Processes in Sublinear Time

Christophe Dupuy, Francis Bach

We propose a new class of determinantal point processes (DPPs) which can be manipulated for inference and parameter learning in potentially sublinear time in the number of items. T…

Online but Accurate Inference for Latent Variable Models with Local Gibbs Sampling

Christophe Dupuy, Francis Bach

We study parameter inference in large-scale latent variable models. We first propose an unified treatment of online inference for latent variable models from a non-canonical expone…
