    Title: Learning useful and interpretable representations via information regularizations

    Raghu Raghavendra (chair), Aiichiro Nakano, Viktor K Prasanna (outside member)

    EEB 248

    July 17th

    11am~1pm

    Abstract:

    We studied the application of the Information Bottleneck (IB) principle in two machine learning problems. The IB principle suggests learning representations that is maximally relevant to predictions while being maximally compressive about input data, and it is considered as one possible way of explaining the black box in successful deep learning algorithm.

    The first application is analyzing and designing supervised classifier, focusing on the relevance between representation and predictions. We used to observe that entropy regularized log-likelihood (ERLL) was a good model selection criterion when we trained acoustic state classifier for acoustic speech recognition. Starting from IB principle, we derived an approximate lower bound of IB objective that can explain the strength of ERLL in model selection, and accordingly proposed heuristic algorithm that uses entropy to learn classifiers that are both accurate and confident. We demonstrate it on multiple benchmark datasets.

    The second application is unsupervised learning of interpretable representation, focusing on the compression of input data. We proposed a variant of variational autoencoder (VAE) model that jointly learn one representation that encodes absract concepts and one representation that encodes details of input data. This model architecture provides a flexible way of balancing the task of informative features extraction by encoders and samples generation by decoders. We demonstrate it on application of clustering analysis and concept discovery in representation space.

  • NL Seminar-Visual Question Answering the Good, the Bad, and the Ugly

    Fri, Jul 20, 2018 @ 03:00 PM - 04:00 PM

    Information Sciences Institute

    Conferences, Lectures, & Seminars


    Speaker: Wei-Lun Harry Chao , USC

    Talk Title: Visual Question Answering: the Good, the Bad, and the Ugly

    Series: Natural Language Seminar

    Abstract: Visual question answering Visual QA requires comprehending and reasoning with both visual and language information, a characteristic ability that AI should strive to achieve. Merely in the past three years, over a dozen datasets have been released, together with many learning based models that have been narrowing the gap between the humans performance and the machines. On one popular dataset VQA, the state of the art model achieves 71.4 percent accuracy, just percent shy of that by humans.

    While seemingly remarkable, it needs a deeper investigation on what knowledge the machine actually learns does it understand the multi modal information? Or it relies on and over fits to the incidental dataset statistics. Moreover, current experimental setups mainly focus on training and testing within the same dataset. It is unclear how the learned model can be applied to the real environment where both the visual and language data might have mismatch.

    In this talk, I will present our recent studies to answer these questions. We show that the dataset design has a significant impact on what a model learns. Specifically, the resulting model can ignore the visual information, the question, or both while still doing well on the task. We thus propose automatic procedures to remedy such design deficiencies. We then show that the mismatch in language hinders transferring a learned model across datasets. To this end, we develop a domain adaptation algorithm for Visual QA to facilitate knowledge transfer. Finally, I will present a probabilistic framework of Visual QA algorithms to effectively leverage the answer semantics, drastically increasing the transferability. I will conclude the talk with future directions to advance Visual QA.

  • Electrical Engineering Seminar

    Fri, Jul 20, 2018 @ 03:30 PM - 04:30 PM

    Ming Hsieh Department of Electrical and Computer Engineering

    Conferences, Lectures, & Seminars


    Speaker: Yi-Hsuan Yang , Academia Sinica, Taiwan

    Talk Title: Machine Learning for Creative AI Applications in Music

    Abstract: In this talk, I will briefly introduce three latest projects in our lab at Academia Sinica on creative applications in music, including the singing voice separation project, GenMusic (music generation) project, and the DJnet project. The first project is about separating the singing voice from the musical accompaniments, which can be used as a pre-processing step for many music related applications. The second project is about learning from massive collection of MIDI files to generate multi-track music by a generative adversarial network (GAN). The generative model can be used for generating music either from scratch, or by accompanying a given (instrument) track. The third project is about creating an AI DJ that knows how to manipulate, sample, and sequence musical pieces to create a personalized playlist. The goal of these projects is to enrich the way people create and interact with music in their daily lives, using the latest machine learning (deep learning) techniques.

    Biography: Yi-Hsuan Yang is an Associate Research Fellow with Academia Sinica. He received his Ph.D. degree in Communication Engineering from National Taiwan University in 2010. He is also a Joint-Appointment Associate Professor with the National Cheng Kung University, Taiwan. His research interests include music information retrieval, affective computing, multimedia, and machine learning. Dr. Yang was a recipient of the 2011 IEEE Signal Processing Society Young Author Best Paper Award, the 2012 ACM Multimedia Grand Challenge First Prize, the 2014 Ta-You Wu Memorial Research Award of the Ministry of Science and Technology, Taiwan, and the 2015 Best Conference Paper Award of the IEEE Multimedia Communications Technical Committee. He is an author of the book Music Emotion Recognition (CRC Press 2011). In 2014, he served as a Technical Program Co-Chair of the International Society for Music Information Retrieval Conference (ISMIR). In 2016, he started his term as an Associate Editor for the IEEE Transactions on Affective Computing and the IEEE Transactions on Multimedia. Dr. Yang is a senior member of the IEEE.
