Balancing Knowledge Delivery and Emotional Comfort in Healthcare Conversational Systems

Shang-Chi Tsai, Yun-Nung Chen

With the advancement of large language models, many dialogue systems are now capable of providing reasonable and informative responses to patients' medical conditions. However, whe…

QuaRot: Outlier-Free 4-Bit Inference in Rotated LLMs

Saleh Ashkboos, Amirkeivan Mohtashami, Maximilian L. Croci +6

We introduce QuaRot, a new Quantization scheme based on Rotations, which is able to quantize LLMs end-to-end, including all weights, activations, and KV cache in 4 bits. QuaRot rot…

DenseFormer: Enhancing Information Flow in Transformers via Depth Weighted Averaging

Matteo Pagliardini, Amirkeivan Mohtashami, Francois Fleuret +1

The transformer architecture by Vaswani et al. (2017) is now ubiquitous across application domains, from natural language processing to speech processing and image understanding. W…

Social Learning: Towards Collaborative Learning with Large Language Models

Amirkeivan Mohtashami, Florian Hartmann, Sian Gooding +3

We introduce the framework of "social learning" in the context of large language models (LLMs), whereby models share knowledge with each other in a privacy-aware manner using natur…

MEDITRON-70B: Scaling Medical Pretraining for Large Language Models

Zeming Chen, Alejandro Hernández Cano, Angelika Romanou +17

Large language models (LLMs) can potentially democratize access to medical knowledge. While many efforts have been made to harness and improve LLMs' medical knowledge and reasoning…

CoTFormer: A Chain-of-Thought Driven Architecture with Budget-Adaptive Computation Cost at Inference

Amirkeivan Mohtashami, Matteo Pagliardini, Martin Jaggi

Scaling language models to larger and deeper sizes has led to significant boosts in performance. Even though the size of these models limits their application in compute-constraine…

Landmark Attention: Random-Access Infinite Context Length for Transformers

Amirkeivan Mohtashami, Martin Jaggi

While Transformers have shown remarkable success in natural language processing, their attention mechanism's large memory requirements have limited their ability to handle longer c…

Learning Translation Quality Evaluation on Low Resource Languages from Large Language Models

Amirkeivan Mohtashami, Mauro Verzetti, Paul K. Rubenstein

Learned metrics such as BLEURT have in recent years become widely employed to evaluate the quality of machine translation systems. Training such metrics requires data which can be…

Special Properties of Gradient Descent with Large Learning Rates

Amirkeivan Mohtashami, Martin Jaggi, Sebastian Stich

When training neural networks, it has been widely observed that a large step size is essential in stochastic gradient descent (SGD) for obtaining superior models. However, the effe…

Characterizing & Finding Good Data Orderings for Fast Convergence of Sequential Gradient Methods

Amirkeivan Mohtashami, Sebastian Stich, Martin Jaggi

While SGD, which samples from the data with replacement is widely studied in theory, a variant called Random Reshuffling (RR) is more common in practice. RR iterates through random…

Masked Training of Neural Networks with Partial Gradients

Amirkeivan Mohtashami, Martin Jaggi, Sebastian U. Stich

State-of-the-art training algorithms for deep learning models are based on stochastic gradient descent (SGD). Recently, many variations have been explored: perturbing parameters fo…
