Title: Large Scale Data Analytics for Airborne Imagery

Speaker: Prof. Gaurav Sharma, Univ. of Rochester

Time and Date: 11 AM, September 10, 2019

Venue: Golden Jubilee Hall, ECE

 

Abstract

 The widespread availability of high resolution aerial imagery covering wide geographical areas is spurring a revolution in large scale visual data analytics. Specifically, modern aerial wide area motion imagery (WAMI) platforms capture large high resolution at rates of 1-3 frames per second. The sequences of images, which individually span several square miles of ground area, represent rich spatio-termporal datasets that are key enablers for new applications. The effectiveness of such analytics can be enhanced by combining WAMI with alternative sources of rich geo-spatial information such as road maps or prior georegistered images. We present results from our recent research in this area covering three topics. First, we describe a novel method for pixel accurate, real-time registration of vector roadmaps to WAMI imagery based on moving vehicles in the scene. Next, we present a framework for tracking WAMI vehicles across multiple frames by using the registered roadmap and a new probabilistic framework that allows us to better estimate associations across multiple frames in a computationally tractable algorithm. Finally, in the third part, we highlight, how we can combine structure from motion and our proposed registration approach to obtain 3D georegistration for use in application such as change detection. We present results on multiple WAMI datasets, including nighttime infrared WAMI imagery, highlighting the effectiveness of the proposed methods through both visual and numerical comparisons.

Abstract:

Brains are endowed with innate models that can learn effective informational and reasoning prototypes of the various objects and concepts in the real world around us. A distinctive hallmark of the brain, for example, is its ability to automatically discover and model objects, at multi-scale resolutions, from repeated exposures to unlabeled contextual data and then to be able to robustly detect the learned objects under various non-ideal circumstances, such as partial occlusion and different view angles. Replication of such capabilities in a machine would require three key ingredients: (i) access to large-scale perceptual data of the kind that humans experience, (ii) flexible representations of objects, and (iii) an efficient unsupervised learning algorithm. The Internet fortunately provides unprecedented access to vast amounts of visual data. The first part of this work will focus on our recent work that leverages the availability of such data to develop a scalable framework for unsupervised learning of object prototypes—brain-inspired flexible, scale, and shift invariant representations of deformable objects (e.g., humans, motorcycles, cars, airplanes) composed of parts, their different configurations and views, and their spatial relationships. We apply our framework to various datasets and show that our approach is computationally scalable and can construct accurate and operational part-aware object models much more efficiently than in much of the recent computer vision literature. We also present efficient algorithms for detection and localization in new scenes of objects and their partial views. The second part of this work will focus on processing large scale textual data, wherein our algorithms can create semantic concept-level maps from unstructured data sets. Finally we will conclude with the outlines of a general framework of contextual unsupervised learning that can remove many of the scalability and robustness limitations of existing supervised frameworks that require large amounts of labeled training sets and mostly act as impressive memorization engines.

Achuta Kadambi

Host faculty : Dr. Chandra Sekhar Seelamantula

Time & Venue : 14th June, 2019, Friday on 4:00 PM at MMCR first floor, Electrical Engineering Department, IISc.

Abstract: Today, deep learning is the de facto approach to solving many computer vision problems. However, in adopting deep learning, one may overlook a subtlety: the physics of how light interacts with matter. By exploiting these previously overlooked subtleties, we will describe how we can rethink the longstanding problem of 3D reconstruction. Using the lessons learned from this prior work, we will then discuss the future symbiosis between physics and machine learning, and how this fusion can transform many application areas in imaging.

Title: Coherence Diversity in Multi-User Networks

Speaker:  Prof. Aria Nosratinia
Electrical Engineering Department
University of Texas at Dallas

Date/Time: 18 March 2019, 4 PM

Venue: Golden Jubilee Seminar Hall, Dept. of ECE

Abstract:
Although links in a wireless network may easily experience different
coherence conditions, the literature in communication and information
theory has mostly concentrated on coherence intervals of equal length
throughout the network. This talk explores new and exciting developments
in the field of non-uniform fading dynamics, where the disparity of
fading intervals can lead to new gains in multi-user networks that are
distinct from previously known phenomena. Product superposition, a new
tool developed to address non-uniform dynamics, will be introduced.
We begin by studying the application of this tool in the 2-user
broadcast channel. The results will be extended to the multi-user
broadcast channel. Disparity in either coherence bandwidth, or both
coherence time & bandwidth, will be discussed. Time permitting, the
interplay with non-uniform or stale CSI, and the interactions of
product superposition with retrospective interference alignment will
be discussed.

TITLE         : Role and Strengths of Adversarial Perturbations in Deep Learning
Date/Time   : February 21, 2019 (Thursday) 11:00 AM
Venue          : 102 CDS Seminar Hall.


ABSTRACT

Deep neural network architecture based models have high expressive power and learning ca-pacity. Due to several advancements, deep learning based models have shown very high accuracies on challenging databases including face databases. However, they are essentially a black box method since it is not easy to mathematically formulate the functions that are learned within its many layers of repre-sentation. Realizing this, many researchers have started to design methods to exploit the drawbacks of deep learning based algorithms questioning their robustness and exposing their singularities.

Adversarial attacks on automated classification systems has been an area of interest for a long time. In 2002, Ratha et al. proposed eleven points of attacks on a biometric/face recognition system. For in-stance, an adversary can operate at the input/image level or the decision level, and lead to incorrect face recognition results. The research on adversarial learning for attacking face recognition systems has three key components: (i) creating adversarial images, (ii) detecting whether an image is adversely altered or not, and (iii) mitigating the effect of the adversarial perturbation process. These adversaries create dif-ferent kinds of effect on the input and detecting them requires the application of a combination of hand-crafted as well as learnt features; for instance, some of the existing attacks can be detected using prin-cipal components while some hand-crafted attacks can be detected using well defined image processing operations. Therefore, it is important to detect the adversarial perturbations and mitigate the effect caused due to such adversaries using ensemble of defense algorithms. While majority of the research in adversarial perturbations focus on attacking deep learning models, in this talk, we will also connect how adversarial perturbations can be used for building Trusted-AI systems. With two threads on this direc-tion, we will discuss privacy preserving applications in faces as well as a novel concept of Data Fine-tuning.

TITLE         : Multisensory Integration in the Brain

Date/Time   : February 14, 2019 (Thursday) 04:00 PM

Venue          : 102 CDS Seminar Hall.

 ABSTRACT

Multisensory integration is a phenomenon by which the brain infers coherent and robust representations using incoming sensory information in different modalities. It plays a significant role in perception as well as all cognitive functions from memory to decision-making. Because of its inherent multimodal nature, it is harder to study in experiments and many open questions exist regarding its underlying neural mechanisms. In my research, I approach this problem from two different perspectives using computational models in conjunction with experimental data. In the first method, I focus on understanding the neurobiological mechanisms that might support multisensory integration. I will show that deep neural networks trained using predictive coding can account for neuronal properties like selectivity and sparsity along the visual cortical hierarchy. In the second method focus shifts to identifying the underlying structures necessary for multisensory integration rather than the intermediate mechanisms that yield these structures

 BIOGRAPHY

Computational Imaging with Few Photons, Electrons, or Ions

 

Speaker: Prof. Vivek Goyal, Boston University

 

Date and Time: December 3, 2018, 11 AM to 12 noon (coffee/tea:
10.45 AM)

 

Venue: Multimedia Classroom, Electrical Engineering Department, IISc.

 

Abstract:

LIDAR systems use single-photon detectors to enable long-range reflectivity and depth imaging.  By exploiting an inhomogeneous Poisson process observation model and the typical structure of natural scenes, first-photon imaging demonstrates the possibility of accurate LIDAR with only 1 detected photon per pixel, where half of the detections are due to (uninformative) ambient light.  I will explain the simple ideas behind first-photon imaging. Then I will touch upon related subsequent works that mitigate the limitations of detector arrays, withstand 25-times more ambient light, allow for unknown ambient light levels, and capture multiple depths per pixel. The philosophy of modeling at the level of individual particles is also at the root of current work in focused ion beam microscopy.
