Shikib Mehri

PhD @ CMU

Graduate Research Assistant @ DialRC


Currently, I'm a PhD student at CMU's Language Technologies Institute. I'm working on dialog systems, advised by Maxine Eskenazi as part of the DialRC group.

Some recent news:

  • Doing an internship at Amazon this summer! Excited to be working with Dilek Hakkani-Tur and Mihail Eric.

  • One paper accepted to SIGdial 2020. Details to follow soon.

  • Two papers accepted to ACL 2020. One paper introduces the USR metric and another examines none-of-the-above prediction in dialog retrieval

  • I was accepted to continue my PhD at CMU! Estimated graduation is 2022.

  • Won best paper at SIGdial 2019 for our work on Structured Fusion Networks!

  • A paper accepted to EMNLP 2019 titled Multi-Granularity Representations of Dialog. We show that you can learn multipe granularities of representation by controlling the negative candidates during the task of dialog retrieval.

  • Two papers accepted at SIGdial 2019!. I'll be giving a talk on Structured Fusion Networks and will have a poster on our multi-reference dataset. I'll also be giving a talk at the Dialog for Good workshop about our dialog system for seniors, CMU GetGoing.

  • I had a paper accepted to ACL 2019 on dialog-specific pretraining objectives. We introduce several novel pretraining objectives that obtain good performance results and show pretraining to result in better generalizability, less data-hungry models and faster convergence.

  • I had a publication accepted to NeurIPS 2018! My paper introduces the Middle-Out Decoder which uses self-attention to generate sequences from the middle-out rather than left-to-right.

Feel free to contact me if you're interested in my work, have an interested opportunity, or you just want to chat about NLP or deep learning!

Publications


Experience


  • May 2020 - Aug 2020

    Scientist Intern

    As a scientist intern on the Alexa Conversational AI team, I was mentored by Dilek Hakkani-Tur and Mihail Eric. Two papers on the way with SOTA results 5 dialog tasks (including big gains on MultiWOZ + intent prediction).

  • Aug 2018 - Aug 2022 (Expected)

    MS + PhD

    A student in the Language Technologies Institute at Carnegie Mellon University. I am supervised by Profs. Maxine Eskenazi

  • May 2018 - Aug 2018

    Scientist Intern

    As a scientist intern on the Alexa AI team, I developed novel approaches for conversational speech recognition, yielding significant improvements in both quantitative and qualitative evaluation. A publication is in the works.

  • Sept 2017 - July 2018

    Research Assistant

    Worked with Prof. Leonid Sigal on video captioning. I developed a novel middle-out sequence decoder, attaining state of the art results. A publication has been accepted to NeurIPS 2018.

  • Jan 2018 - Apr 2018

    Graduate Teaching Assistant

    Teaching assistant for Multi-Modal Deep Learning. Assisted with the design/development of assignments, as well as general TA duties. One of few undergraduates to ever TA a graduate class.

  • June 2017 - Sept 2017

    Data Scientist Intern

    As part of the Windows Feedback Analysis team, I constructed a number of deep learning based classification and semantic similarity models for the purposes of natural language understanding.

  • Jan 2017 - Mar 2017

    Software Engineering Intern

    On the Machine Translation team, I worked on the implementation of a number of subword Neural Machine Translation models to ultimately improve post and comment translation on Facebook.

  • Aug 2016 - Aug 2018

    Bioinformatics Research Assistant

    As a member of the Wasserman lab at CMMT, I designed and implemented algorithms for read alignment on a graph based representation of the reference genome.

  • Aug 2016 - May 2017

    Research Assistant

    Worked with Prof. Giuseppe Carenini on the problem of thread disentanglement in multiparticipant chats. My approach employed novel strategies (including leveraging a weakly-supervised LSTM classifier) to attain state of the art results. I presented a publication at IJCNLP 2017.

  • Sept 2014 - Aug 2015
    Jan 2016 - Aug 2016

    Computer Science Teaching Assistant

    Taught CPSC 110, CPSC 213 (Computer Systems), CPSC 313 (Operating Systems), CPSC 304 (Databases). I ran labs containing 30+ students, lectured in tutorials, invigilated exams, held office hours and graded assignments and exams.

  • May 2016 - July 2017

    Software Engineering Intern

    On the Ads Targeting Modeling team, I worked on generating/evaluating user-interest mappings. I also constructed an incredibly accurate classification model to predict the correct categorization of a given interest.

  • Oct 2015 - June 2017

    Co-founder & CTO

    As the Chief Technology Officer of IntelliMed, a funded startup, I led developers in building an application which automates the process of writing pharmacy medication reviews for patients.

  • Sept 2015 - Dec 2015

    Software Engineering Intern

    Implemented functionality to detect incorrectly configured network switches and to change the assignment strategies for linerate capable ports in order to decrease downtime.

  • September 2013 - May 2018

    Honours Computer Science

    I recently graduated with a major in Honours Computer Science (with co-op). I graduated with a 4.20 cumulative GPA as well as a 4.33 in-major GPA.

  • Sept 2011 - May 2013

    University Transition Program

    One of 20 students to attend this rigorous, highly-accelerated program that condenses five years of highschool into two. I completed the program at the age of 14, leading to an early entrance to university.
