Every Sample Counts: Supervised Fine-Tuning of Language Models with Pointwise Constraints

Ignacio Hounie, Ignacio Boero, Alejandro Ribeiro

Fine-tuning language models often requires enforcing constraints on individual inputs without compromising downstream performance. Existing constrained alignment methods impose con…

Everywhere Learning: Artificial Intelligence with Pointwise Constraints

Ignacio Boero, Ignacio Hounie, Luiz Chamon +1

Everywhere learning is a new paradigm whereby Artificial Intelligence (AI) systems are trained to satisfy loss constraints with probability one over the data distribution. This is…

Infinity Search: Approximate Vector Search with Projections on q-Metric Spaces

Antonio Pariente, Ignacio Hounie, Santiago Segarra +1

An ultrametric space or infinity-metric space is defined by a dissimilarity function that satisfies a strong triangle inequality in which every side of a triangle is not larger tha…

AL-CoLe: Augmented Lagrangian for Constrained Learning

Ignacio Boero, Ignacio Hounie, Alejandro Ribeiro

Despite the non-convexity of most modern machine learning parameterizations, Lagrangian duality has become a popular tool for addressing constrained learning problems. We revisit A…

Distilling On-device Language Models for Robot Planning with Minimal Human Intervention

Zachary Ravichandran, Ignacio Hounie, Fernando Cladera +3

Large language models (LLMs) provide robots with powerful contextual reasoning abilities and a natural human interface. Yet, current LLM-enabled robots typically depend on cloud-ho…

LoRTA: Low Rank Tensor Adaptation of Large Language Models

Ignacio Hounie, Charilaos Kanatsoulis, Arnuv Tandon +1

Low Rank Adaptation (LoRA) is a popular Parameter Efficient Fine Tuning (PEFT) method that effectively adapts large pre-trained models for downstream tasks. LoRA parameterizes mode…
