Abstract
\nSince it is increasingly h arder to opt out from interacting with AI technology\, people demand that AI is capable of maintaining contracts such that it supports agency and ov ersight of people who are required to use it or who are affected by it. To help those people create a mental model about how to interact with AI sys tems\, I extend the underlying models to self-explain—predict the label/an swer and explain this prediction. In this talk\, I will present how to gen erate (1) free-text explanations given in plain English that immediately t ell users the gist of the reasoning\, and (2) contrastive explanations tha t help users understand how they could change the text to get another labe l.
\nBiography
\nAna Marasović is a postdocto ral researcher at the Allen Institute for AI (AI2) and the Paul G. Allen S chool of Computer Science & Engineering at University of Washington. Her r esearch interests broadly lie in the fields of natural language processing \, explainable AI\, and vision-and-language learning. Her projects are mot ivated by a unified goal: improve interaction and control of the NLP syste ms to help people make these systems do what they want with the confidence that they’re getting exactly what they need. Prior to joining AI2\, Ana o btained her PhD from Heidelberg University.
\nHow to pronounce my name: the first name is Ana like in Spanish\, i.e.\, with a long “a” like in “water”\; regarding the last name: “mara” as in actress mara wilso n + “so” + “veetch”.

\nAdvanced neural language m odels have grown ever larger and more complex\, pushing forward the limits of language understanding and generation\, while diminishing interpretabi lity. The black-box nature of deep neural networks blocks humans from unde rstanding them\, as well as trusting and using them in real-world applicat ions. This talk will introduce interpretation techniques that bridge the g ap between humans and models for developing trustworthy natural language p rocessing
\n (NLP). I will first show how to explain black-box models and evaluate their explanations for understanding their p rediction behavior. Then I will introduce how to improve the interpretabil ity of neural language models by making their decision-making transparent and rationalized. Finally\, I will discuss how to diagnose and improve mod els (e.g.\, robustness) through the lens of explanations. I will conclude with future research directions that are centered around model interpretab ility and committed to facilitating communications and interactions betwee n intelligent machines\, system developers\, and end users for long-term t rustworthy AI.Biography
