Horseshoes with Heavy Tails

In high dimensional problems, the usual two groups problem of model selection is impossible due to the combinatorial complexity of the model space. In recent years, a set of one group models that approximates the two groups problem have been developed. Of these, the Horseshoe prior is is perhaps the most famous and places a Beta(1/2,1/2) prior on the local shrinkage parameters. There are many modifications and extensions of this framework, and we propose a new modification. Specifically, we model the local shrinkage parameter as a Beta(p,1-p) for each parameter under consideration in order to mimic the model selection problem. Placing priors on the p produces a prior distribution with extremely heavy tails that produces both very strong shrinkage of small signals and unbiased estimation of large signals, producing overall better risk behavior.

Andrew Womack is an Assistant Professor and Zikun Yang is a PhD candidate in the Department of Statistics. Their joint research efforts focus on theoretical and algorithmic aspects of model selection from a Bayesian perspective.

Scene Understanding for Robotic Applications

Scene understanding from images opens the doorway for solving various complex tasks such as visual navigation, object manipulation and reasoning about the world in 3D. These challenging tasks can be better tackled with the availability of depth information. This talk covers techniques that effectively exploit both the image data and the depth data for scene understanding. First, a semantic label propagation framework is presented that utilizes a few annotated keyframes and propagates the annotated labels to a large number of unlabeled video frames. The proposed technique alleviates the need for a labor-intensive manual annotation effort, and the propagated labels have been utilized to improve a deep neural network model for semantic segmentation - the task of simultaneously segmenting and labeling an image. This talk concludes with an approach to generate training data for distant objects in outdoor scenes and proposes two deep learning solutions for depth recovery of those objects.

Reza is a Postdoctoral Associate in the Department of Informatics, Computer Science, and Engineering (SICE) at Indiana University Bloomington. He received his Ph.D. in Computer Science from George Mason University in 2018 and M.S. in Computer Science from Drexel University in 2011. His research focuses on developing novel algorithms for perception tasks such as semantic segmentation, object detection exploiting the 3D information.

• Wednesday, September 12. Grigory Yaroslavtsev (IU Computer Science)

I will describe Badger Rampage, a simple general framework for designing practical algorithms for d-dimensional balanced partitioning of graphs with several billions of vertices and up to 10^12 edges. Badger Rampage is based on applying noisy projected gradient descent to a non-convex relaxation of the problem. For an appropriately chosen relaxation, the gradient descent step can be implemented simply as local averaging of the neighboring values. The technical core of our work is optimizing the computationally expensive projection step for which we give an algorithm with complexity O(|V| log^d |V|) for d <= 2. Experiments on Apache Giraph using subsets of the Facebook graph show comparable or superior performance against existing literature on one-dimensional graph partitioning with the added benefits of simplicity and generalizability to the multi-dimensional case. Analysis of convergence properties of Badger Rampage is left as an open problem.

Dimensionality Reduction Techniques for Deep Learning Based Machine Vision

In this talk, sparse representation based and manifold optimization based image signal processing techniques are mainly discussed. These two techniques are ones of the dimension reduction methods which reduce the high dimensionality of system matrix to reduce the system complexity. Especially for deep learning process, the back propagation process for training is a time consuming process because of its iteration based optimization of nonlinear/nonconvex high dimensional cost function. While recent technologies such as deep learning make statistical decision more accurate, computational time to handle high dimensional cost function for big data is getting slower. For above reasons, dimension reduction is a key technology to achieve real-time process. Among lots of dimension reduction related techniques, sparse representation is one of the matrix factorization techniques to factor to low dimension matrices using sparse properties, and manifold optimization is a kind of piece-wise linear approximation of nonconvex/nonlinear space cost function which represents on non-Euclidean space. Additionally, random projection and tensor factorization techniques will be discussed for another possibilities to speed up the optimization processes.

Polynomial-time probabilistic reasoning with partial observations via implicit learning in probability logics

Standard approaches to probabilistic reasoning require that one possesses an explicit model of the distribution in question. But, the empirical learning of models of probability distributions from partial observations is a problem for which efficient algorithms are generally not known. In this work we consider the use of bounded-degree fragments of the "sum-of-squares" logic as a probability logic. Prior work has shown that we can decide refutability for such fragments in polynomial-time. We propose to use such fragments to answer queries about whether a given probability distribution satisfies a given system of constraints and bounds on expected values. We show that in answering such queries, such constraints and bounds can be implicitly learned from partial observations in polynomial-time as well. It is known that this logic is capable of deriving many bounds that are useful in probabilistic analysis. We observe that it furthermore captures key polynomial-time fragments of resolution. Thus, these fragments are also quite expressive.

Best Arm Identification in the Multi-armed Bandit

The multi-armed bandit model is a basic setting in reinforcement learning. It is one of the simplest model to capture the tradeoff between exploration and exploitation. It has many applications such as A/B testing, crowdsourcing, and personalized recommendation. In the pure exploration form, perhaps one of the most popular goals is to identify the best arm which is the arm with the largest mean. In this talk, I will give a tutorial on best arm identification in the multi-armed bandit model.

Best Arm Identification in Linear Bandits

In the multi-arm bandit setting one considers a row of slot machines, each of which gives a reward based on some distribution, and asks questions such has how to identify the best machine, or how to maximize the sum of the expected rewards after a sequence of pulls. In this talk we consider the special setting where each of the rewards depends linearly on an unknown parameter $\theta$, and our goal is to identify the slot machine (arm) with the largest expected reward. We present an algorithm that is built upon a new estimator for $\theta$ that produces better theoretical guarantees and experimental results than previous algorithms. This is joint work with Chao Tao and his advisor Yuan Zhou.

Two studies in egocentric computer vision

From Coarse Attention to Fine-Grained Gaze: A Two-stage 3D Fully Convolutional Network for Predicting Eye Gaze in First Person Video

Zehua Zhang

While predicting where people will look when viewing static scenes has been well- studied, a more challenging problem is to predict gaze within the first-person, ego-centric field of view as people go about daily life. This problem is difficult because where a person looks depends not just on their visual surroundings, but also on the task they have in mind, their own internal state, their past gaze patterns and actions, and non-visual cues (e.g., sounds) that might attract their attention. Using data from head-mounted cameras and eye trackers that record people’s egocentric fields of view and gaze, we propose and learn a two-stage 3D fully convolutional network to predict gaze in each egocentric frame. The model estimates a coarse attention region in the first stage, combining it with spatial and temporal features to predict a more precise gaze point in the second stage. We evaluate on a public dataset in which adults carry out specific tasks as well as on a new challenging dataset in which parents and toddlers freely interact with toys and each other, and demonstrate that our model outperforms state-of-the-art baselines.

Joint Person Segmentation and Identification in Synchronized First- and Third-person Videos

Yuchen Wang

In a world of pervasive cameras, public spaces are often captured from multiple perspectives by cameras of different types, both fixed and mobile. An important problem is to organize these heterogeneous collections of videos by finding connections between them, such as identifying correspondences between the people appearing in the videos and the people holding or wearing the cameras. In this paper, we wish to solve two specific problems: (1) given two or more synchronized third-person videos of a scene, produce a pixel-level segmentation of each visible person and identify corresponding people across different views (i.e., determine who in camera A corresponds with whom in camera B), and (2) given one or more synchronized third-person videos as well as a first-person video taken by a mobile or wearable camera, segment and identify the camera wearer in the third-person videos. Unlike previous work which requires ground truth bounding boxes to estimate the correspondences, we perform person segmentation and identification jointly. We find that solving these two problems simultaneously is mutually beneficial, because better fine-grained segmentation allows us to better perform matching across views, and information from multiple views helps us perform more accurate segmentation. We evaluate our approach on two challenging datasets of interacting people captured from multiple wearable cameras, and show that our proposed method performs significantly better than the state-of-the-art on both person segmentation and identification.

New Lower and Upper Bounds for Submodular Maximization in Streaming

Many tasks in machine learning and data mining, such as data diversification, non-parametric learning, kernel machines, clustering etc., require extracting a small but representative summary from a massive dataset. Often, such problems can be posed as maximizing a submodular set function subject to a cardinality constraint. We consider this question in the streaming setting, where elements arrive over time at a fast pace and thus we need to design an efficient, low-memory algorithm. One such method, proposed by Badanidiyuru et al.(2014), always finds a 0.5-approximate solution. Can this approximation factor be improved? We answer this question affirmatively by designing a new algorithm SALSA for streaming submodular maximization.

SALSA is the first low-memory, single-pass algorithm that improves the factor 0.5, under the natural assumption that elements arrive in a random order. We also show that this assumption is necessary, i.e., that there is no such algorithm with better than 0.5-approximation when elements arrive in arbitrary order. Our experiments demonstrate that SALSA significantly outperforms the state of the art in applications related to exemplar-based clustering, social graph analysis, and recommender systems. In this talk I will outline our proof of the lower bound and present the main ideas behind SALSA.

This is based on a joint work with Ashkan Norouzi-Fard, Jakub Tarnawski, Amir Zandieh, Aida Mousavifar, and Ola Svensson.

He works to tap into and enhance the amazing human ability to create concepts, combine concepts, and share concepts, by lining up formal representations and what they represent. To this end, in the short term, he develops programming languages that divide what to do and how to do it into modules that can be built and reused separately. In particular, he develops so-called probabilistic programming languages, which divide stochastic models and inference algorithms into modules that can be built and reused separately.
