Title: Powering fashion e-commerce with computer vision and deep learning

by Vishnu Vardhan Makkapati, Architect, Myntra,

Time & Date: 11:00 AM, Wednesday, April 25, 2018
Venue: CDS Seminar Hall (Room No: 102), IISc.

Abstract:

Fashion is a highly visual field. Images, though a rich source of domain information, are extremely subjective, and their interpretation is more art than science. Our goal is to teach a machine to interpret these varied images in a consistent manner, while eliminating subjectivity from the process. We have used our industry leading fashion catalog to understand and interpret the inherent fine-grained details in images. These details will help power very interesting use cases in fashion e-commerce such as cataloging, purchasing, personalisation etc. In this talk, we will present an overview of our work on mining catalog images using deep learning and computer vision. We will also discuss some of our recent work on generation of fashion designs using Generative Adversarial Networks.

Title: “Hearing Assessment Technologies (Audiometry)
and some new challenges”
Date/Time: 26th April 2018, Thursday, 4-5pm
Venue: Golden Jubilee Seminar Hall, ECE Dept, IISc
Tea/Coffee: 3.45pm

Abstract:
The auditory system has unique abilities that enable to person to carry out tasks such as listening in noise, detecting differences in sound object, localizing sounds, music appreciation and learning languages, activities that are deceptively simple. Hearing assessment (common parlance referred to as audiometry) refers to behavioural and physiological tests to assess function and sometimes “structure” of the different components of the auditory pathway. For this, a number of stimuli varying from the simple pure tones to synthetic speech which are presented in different modes, at different SNRs, in an attempt to simulate real life conditions, but more often to diagnose the problem. Creating appropriate stimuli and calibration is an issue.

Speaker Bio:

Title: Image-based Crowd Analytics
—————————————————-
by Vishwanath A. Sindagi, Rutgers University,

Time & Date: 11:00 AM, Thursday, April 19, 2018
Venue: CDS Seminar Hall (Room No: 102), IISc.

Abstract:

The study of human behavior based on computer vision techniques has gained a lot of interest in recent years. In particular, the behavioral analysis of crowded scenes is of great interest due to a variety of reasons. Exponential growth in the world population and the resulting urbanization has led to an increased number of activities involving high density crowd such as sporting events, political rallies, public demonstrations, thereby resulting in more frequent crowd gatherings in the recent years. In such scenarios, it is essential to analyze crowd behavior for better management, intelligence gathering, safety and security. In this talk, I will present some of my recent work on developing algorithms for crowd analytics, including crowd counting from unconstrained imagery, crowd segmentation and human detection from crowded scenes. I will conclude my talk by describing several promising directions for future research.

Bio:

Vishwanath is a second year PhD student in Dept. Of Electrical & Computer Engineering at Rutgers University. He is being advised by Prof. Vishal M Patel. Prior to joining Rutgers, he worked for Samsung R&D Bangalore and AllGo Embedded Systems. He graduated from IIIT-Bangalore with a Master’s degree in Information Technology. His current research is on computer vision and machine learning with a specific focus on crowd analytics, face detection, applications of generative modeling, domain adaptation and low-level vision.

Title: Deep Representations, Adversarial Learning and Domain Adaptation for Some Computer Vision Problems

Abstract:
Recent developments in deep representation-based methods for many computer vision problems have knocked down many research themes pursued over the last four decades. In this talk, I will discuss methods based on deep representations, adversarial learning and domain adaptation for designing robust computer vision systems with applications in unconstrained face and action verification and recognition, expression recognition, subject clustering and attribute extraction. The face and action recognition system being built at UMD is based on fusing multiple deep convolutional neural networks (DCNNs) trained using publicly available still
and video face data sets. I will then discuss some new results on generative adversarial learning and domain adaptation for improving the robustness of the recognition system.

Title: Beyond Worst Case – When data size increases faster than Moore’s law, one has to sacrifice worst-case performance to improve the average-case performance.
Speaker: Vivek Bagaria, Stanford University, USA
Time and Date: 4pm, Thursday, Dec. 21, 2017
Venue: Golden Jubilee Hall, ECE Department, IISc Bangalore

Abstract:

High dimensional median: Computing the medoid of a large number of points in high-dimensional space is an increasingly common operation in many data science problems. We present an algorithm Med-dit which computes the medoid (with high probability) in O(n log n) steps. Med-dit is based on a connection with the multi-armed bandit problem. We empirically evaluate the performance of Med-dit on the Netflix-prize and the single-cell RNA datasets, containing hundreds of thousands of points living in tens of thousands of dimensions, and observe a 5-10x improvement in performance over the current state of the art.

Planted Traveling salesman problem (TSP): Consider a complete graph K_n. The edge weights of a planted hamiltonian path are drawn from distribution P and all other edge weights are drawn from distribution Q. We present an almost-linear time algorithm which solves planted-TSP above information theoretic limit (for certain class of distributions P and Q such as gaussian, poisson etc). We apply this algorithm on Chicago-seq dataset and show a potential improvement in the quality of de novo dna assembly.

Title: Connecting vision and language for Interpretation, Grounding and Imagination
—————————————————-
by Ramakrishna Vedantam, Georgia Tech,

Time & Date: 4:00 pm, Friday, December 22, 2017
Venue: CDS Seminar Hall (Room No: 102), IISc.
Abstract:

The goal of this talk is to explore how modeling deep interactions between vision and natural language can derive more humanlike inferences from machine learning models. We will consider various situations where humans are able to make intuitive inferences, but where machines are not, and show how appropriate algorithmic or computational choices can improve the inferences made by machines and make them more humanlike.

In pursuit of this overarching goal, I will look at three focus areas: interpretation, grounding, and visual imagination. In interpretation, I will study how to go from computer vision to natural language. Specifically, the focus will be on image captioning: the problem of describing an image with a natural language description. Here, I study how to formalize the task of image captioning and create evaluation schemes to make progress towards generating more `human-like’ descriptions and generate image captions which are more aware of the context in which we want to describe an image.

In the second part, I will consider the inverse problem of “grounding” — associating symbols such as “car” with what they refer to in the physical world. A key focus will be on learning word representations grounded in vision or sound, and a study of how such representations can lead to improved retrieval and commonsense reasoning.

Finally, I will talk about recent work on the problem of imagination — consider how easy it is for people to imagine what a “purple hippo” would look like, even though they do not exist. If we instead said “purple hippo with wings”, they
could just as easily create a different internal mental representation, to represent this more specific concept. To assess whether the person has correctly understood the concept, we can ask them to draw a few sketches,
to illustrate their thoughts. We call the ability to map text descriptions of concepts to latent representations and then to images visually grounded semantic imagination. My work will explore how one can modify a class of joint latent variational autoencoder models to perform such grounded semantic imagination.

“Positive trigonometric polynomials: Application to spectral super-resolution”

by
Dr. Kumar Vijay Mishra, IIHR – Hydroscience & Engineering, The University of Iowa, USA.

Date and time: December 20, 2017; 4.30 PM

Venue: Multimedia Classroom, Department of Electrical Engineering, IISc.

Abstract:
We address the problem of super-resolution frequency recovery using prior knowledge of the
structure of a spectrally sparse, undersampled signal with frequencies lying anywhere in the
continuous domain [0, 1]. We devise a general semidefinite program (SDP) to recover these
frequencies using theories of positive trigonometric polynomials (PTP). Our theoretical analysis
shows that given sufficient prior information, perfect signal reconstruction is possible using signal
samples no more than thrice the number of signal frequencies. We extend our PTP formulations to
solve an open problem on the formulation of an equivalent positive semidefinite program for atomic
norm minimization in recovering signals with d-dimensional (d greater than or equal to 2) off-thegrid
frequencies. Finally, we combine SDP and l1-minimization to develop fast versions of our
algorithms.
