Designing Language Models to Think Like Humans

Post-doctoral researcher NLP group Stanford UniversityOrganizer Department of Brain SciencesContact Abstract Show full text abstract about While language models (LMs) show impressive text manipulatio...» While language models (LMs) show impressive text manipulation capabilities, they also lack commonsense and reasoning abilities and are known to be brittle. In this talk, I will suggest a different LMs design paradigm, inspired by how humans understand it. I will present two papers, both shedding light on human-inspired NLP architectures aimed at delving deeper into the meaning beyond words.
The first paper [1] accounts for the lack of commonsense and reasoning abilities by proposing a paradigm shift in language understanding, drawing inspiration from embodied cognitive linguistics (ECL). In this position paper we propose a new architecture that treats language as inherently executable, grounded in embodied interaction, and driven by metaphoric reasoning.
The second paper [2] shows that LMs are brittle and far from human performance in their concept-understanding and abstraction capabilities. We argue this is due to their token-based objectives, and implement a concept-aware post-processing manipulation, showing it matches human intuition better. We then pave the way for more concept-aware training paradigms.

However, such resources are not always accessible. In this seminar, I will discuss alternative paradigms that aim to make better use of both labelled and unlabelled data, drawing inspiration from certain properties of human learning. I will begin by describing our recent work on active learning, continual learning, and learning with label noise. If time permits, I will also discuss some new insights about local overfitting, which can occur even when overfitting (as traditionally defined)is not observed.

Tel Aviv UniversityOrganizer Department of Computer Science and Applied MathematicsContact Abstract Show full text abstract about How does one adapt a pre-trained visual model to novel downs...» How does one adapt a pre-trained visual model to novel downstream tasks without task-specific fine-tuning or changing the model weights? Inspired by prompting in NLP, Visual Prompting is an exciting new paradigm that guides computer vision models to perform downstream tasks by providing visual examples. This talk will focus on designing the underlying self-supervised learning objectives, architectures, and various methods to prompt vision models. Finally, I will discuss in-context learning from a mechanistic interpretability standpoint and share new insights into how transformer models can encode task-specific information in their activation space.
Bio: Amir Bar is a PhD student at Tel Aviv University and Berkeley AI Research. During his PhD, Amir has focused on self-supervised learning in computer vision and pioneered Visual Prompting (or visual in-context learning). Before starting his PhD, he led the research team at the healthcare startup Zebra Medical Vision (recently acquired), where his team developed multiple FDA-approved algorithms now in clinical use in hospitals worldwide. Starting in August 2024, Amir will join FAIR Labs as a postdoctoral researcher, working with Yann LeCun.

Tel Aviv UniversityOrganizer Department of Computer Science and Applied MathematicsContact Abstract Show full text abstract about The computational research of contract design is an exciting...» The computational research of contract design is an exciting new frontier of algorithmic game theory. I demonstrate the potential of the computational approach to shed new light on contract design through two lines of research, on approximation and on learning.
For contracts and approximation, we'll give an overview of currently-known guarantees of linear contracts - which are far from optimal in the worst-case, max-min optimal under uncertainty, and approximately-optimal in the Bayesian setting.
For contracts and learning, we'll discuss how performance-based contractual payments can help mitigate moral hazard when delegating ML-related tasks. Along the way we'll see a connection between contract design and statistical hypothesis testing.
Based on joint works with Tal Alon, Paul Duetting, Ohad Einav, Yingkai Li, Nir Rosenfeld, Tim Roughgarden and Eden Saig.

I will overview our past works on this topic, e.g., 4M (https://4m.epfl.ch/) and MultiMAE (https://multimae.epfl.ch/), follow-up works, and future explorations. If time permits, I will discuss the implications that I see by embodiment for multimodal learning and generally computer vision

TAUOrganizer Department of MathematicsContact Abstract Show full text abstract about Color each vertex of an infinite graph blue with probability...» Color each vertex of an infinite graph blue with probability p and red with probability 1-p, independently among vertices. For which values of p is there an infinite connected component of blue vertices? The talk will focus on this classical percolation problem for the class of planar graphs. Recently, Itai Benjamini made several conjectures in this context, relating the percolation problem to the behavior of simple random walk on the graph. We will explain how partial answers to Benjamini's conjectures may be obtained using the theory of circle packings. Among the results is the fact that the critical percolation probability admits a universal lower bound for the class of recurrent plane triangulations. No previous knowledge on percolation or circle packings will be assumed.

UBCOrganizer Department of MathematicsContact Abstract Show full text abstract about The mixing time and spectral gap of a random walk on the sym...» The mixing time and spectral gap of a random walk on the symmetric group can sometimes be understood in terms of its low dimensional representations (e.g., Aldous' spectral gap conjecture). It turns out that under a mild degree condition involving the step of the group, the same holds for nilpotent groups w.r.t. their one dimensional representations: the spectral gap and the epsilon total variation mixing time of the walk on G are determined by those of the projection of the walk to the abelianization G/[G,G]. We'll discuss some applications concerning the cutoff phenomenon (= abrupt convergence to equilibrium) and the dependence (or lack of!) of the spectral gap and the mixing time on the choice of generators.
As time permits we shall discuss a related result, confirming in the nilpotent setup a conjecture of Aldous and Diaconis concerning the occurrence of cutoff when a diverging number of generators are picked uniformly at random. Joint work with Zoe Huang.

Weizmann Institute of ScienceOrganizer Department of Physics of Complex SystemsContact Abstract Show full text abstract about After a brief introduction related to ultralight (pseudo) sc...» After a brief introduction related to ultralight (pseudo) scalar dark matter, we shall describe the current status of searches for ultralight dark matter (UDM). We explain why modern clocks can be used to search for both scalar and axion dark matter fields. We review existing and new types of well-motivated models of UDM and argue that they all share one key ingredient - their dominant coupling is to the QCD/nuclear sector.
This is very exciting as we are amidst a revolution in the field of dark matter searches as laser excitation of Th-229 with effective precision of 1:10^13 has been recently achieved, which as we show, is already probing uncharted territory of models. Furthermore, Th-229-based nuclear clock can potentially improve the sensitivity to physics of dark matter and beyond by factor of 10^10! It has several important implications to be discussed.
