    Title: Protecting online services from sophisticated attacks

    Date and Time: Monday, 06/27 3:30pm

    Committee:
    Jelena Mirkovic (chair), Barath Raghavan, Ning Wang, Phebe Vayanos and Genevieve Bartlett

    Abstract: Online services are often targets of sophisticated attacks, which aim to overwhelm services or steal user data. In this work, we present solutions, which aim to protect services against sophisticated distributed denial-of-service attacks. These solutions can effectively handle attacks that: (1) involve sending requests which resemble legitimate ones, (2) involve exploiting vulnerabilities that exist in different online services, (3) take advantage of the changing trends in network traffic, and (4) often require online services to get help from their ISPs for mitigation, due to the high volumes of attack traffic.

    Speaker: Katy Felkner, USC/ISI

    Talk Title: Anti-Queer Bias in Large Language Models

    Series: NL Seminar

    Abstract: REMINDER:
    Meeting hosts only admit guests that they know to the Zoom meeting. Hence, you are highly encouraged to use your USC account to sign into Zoom.

    If you are an outside visitor, please inform us at (nlg DASH seminar DASH host AT isi DOR edu beforehand so we will be aware of your attendance and let you in.

    In-person attendance will be permitted for USC ISI faculty, staff, students only. Open to the public virtually via the zoom registration link and online.

    Happy Pride. To close out Pride Month at ISI, this talk will discuss fairness and bias in LLMs as it relates to the LGBTQ community. We will explore current methods for detecting and mitigating bias in LLMs, as well as the lack of current research focusing specifically on homophobic and transphobic biases. The talk will present recent exploratory work on whether and to what extent biases against queer and trans people are encoded in large language models LLMs such as BERT. It will discuss a new method for reducing these biases in downstream tasks: fine-tuning the models on data written by and or about queer people. It will also discuss a new benchmark dataset, WinoQueer, modeled after other bias detection benchmarks but addressing homophobic and transphobic biases. This work was accepted to the Queer in AI workshop at NAACL 2022.

    Biography: Katy Felkner is a rising 3rd year PhD student at USC Information Sciences Institute. Her primary research focus is extremely low-resource machine translation. She is also interest in fairness and bias in large language models. Prior to USC, she received dual bachelors degrees in Computer Science and Letters general humanities from the University of Oklahoma. Her research is supported by an NSF Graduate Research Fellowship. Katy is passionate about making computer science more welcoming for women and queer students.

    Title: Code-switching dialogue systems for language documentation and conversational fluency

    Committee: David Traum, Maja Mataric, Khalil Iskarous (USC Linguistics),Kallirroi Georgila, and Jon May

    Date: June 30th
    Time: 4pm - 5:30 pm
    Zoom: https://usc.zoom.us/j/93068920916


    Abstract:
    Bilingual dialogue systems, or systems that can speak two or more languages within a single conversation, are important systems to consider and implement because many people in the world are bilingual. Code-switching, or switching languages either within a single utterance or between utterances, is a common behavior of bilinguals. Programs that could understand and respond to a user in several languages would allow more users to benefit and interact with dialogue systems comfortably. Current state of the art includes dialogue systems that can speak multiple languages, such as Amazon Alexa that can respond to queries in English or Spanish, among other languages. However, few systems have been developed to process multiple languages being present within a single utterance or to initiate code-switching. I hypothesize that code-switching in dialogue systems can lead to a better user experience and more productive interactions than monolingual systems. I will explore this hypothesis in two applications.The first is a system named DAPEL that records endangered languages through dialogue. The second is a system, named Masheli, designed for language learners to practice conversational fluency. Both applications will focus on Choctaw-English bilingualism; Choctaw is a low-resource and endangered American indigenous language.
