*Monthly online ILFC Seminar: interactions between formal and computational linguistics* https://gdr-lift.loria.fr/monthy-online-ilfc-seminar/

GdR LIFT is happy to announce the two forthcoming sessions of the ILFC seminar on the interactions between formal and computational linguistics:

- 2021/10/12 17:00-18:00 UTC+2: *Christopher Potts* (Stanford

University; 8:00-9:00 UTC-7)

Title: *Causal Abstractions of Neural Natural Language Inference Models*

Abstract: *Neural networks have a reputation for being "black boxes" —

complex, opaque systems that can be studied using only purely behavioral

evaluations. However, much recent work on structural analysis methods

(e.g., probing and feature attribution) is allowing us to peer inside these

models and deeply understand their internal dynamics. In this talk, I'll

describe a new structural analysis method we've developed that is grounded

in a formal theory of causal abstraction. In this method, neural

representations are aligned with variables in interpretable causal models,

and then *interchange interventions* are used to experimentally verify that

the neural representations have the causal properties of their aligned

variables. I'll use these methods to explore problems in Natural Language

Inference, focusing in particular on compositional interactions between

lexical entailment and negation. Recent Transformer-based models can solve

hard generalization tasks involving these phenomena, and our causal

analysis method helps explain why: the models have learned modular

representations that closely approximate the high-level compositional

theory. Finally, I will show how to bring interchange interventions into

the training process, which allows us to push our models to acquire desired

modular internal structures like this.*

Joint work with Atticus Geiger, Hanson Lu, Noah Goodman, and Thomas Icard

Edinburgh; 16:00-17:00 UTC+1)

Title: *Situated Communication*

Abstract: *This talk focuses on how to represent and reason about the content of

conversation when it takes place in an embodied, dynamic environment. I

will argue that speakers can, and do, appropriate non-linguistic events

into their communicative intents, even when those events weren't produced

with the intention of being a part of a discourse. Indeed, non-linguistic

events can contribute an (instance of) a proposition to the content of the

speaker's message, even when her verbal signal contains no demonstratives

or anaphora of any kind. I will argue that representing and reasoning about

discourse coherence is essential to capturing these features of situated

conversation. I will make two claims: first, non-linguistic events affect

rhetorical structure in non-trivial ways; and secondly, rhetorical

structure guides the conceptualisation of non-linguistic events. I will

support the first claim via empirical observations from the STAC corpus


<http://www.irit.fr/STAC/corpus.html)---a> corpus of dialogues that take

place between players during the board game Settlers of Catan. I will

support the second claim via experiments in Interactive Task Learning: a

software agent jointly learns how to conceptualise the domain, ground

previously unknown words in the embodied environment, and solve its

planning problem, by using the evidence of an expert's corrective (verbal)

feedback on its physical actions.*
