Algorithms for Big Data Analytics


We live in the midst of big data. Generation of data is no longer a bottleneck. Analysis of them and extracting useful information are indeed huge bottlenecks. Efficient techniques are needed to process these data. Society at large can benefit immensely from advances in this arena. For example, information extracted from biological data can result in gene identification, diagnosis for diseases, drug design, etc. Market-data information can be used for custom-designed catalogues for customers, supermarket shelving, and so on. Weather prediction and protecting the environment from pollution are possible with the analysis of atmospheric data.

In this talk we present some challenges existing in processing big data. We also provide an overview of some basic techniques. In particular, we will summarize various data processing and reduction techniques. In addition, we will briefly outline the role of machine learning in big data analytics.

Unsupervised Super Resolution Hyperspectral Imaging


One achieves super resolution (SR) in imaging through computational enhancement of the input to yield output images which have improved resolvability of features. This is done by optimizing de-blurring and de-warping operators, and the appropriate leveraging of prior knowledge, and/or information from multiple similar images of the same scene or objects. Modern RGB digital cameras produce SR photographs of a scene by fusing a set of dynamically shifted acquired images of the scene. A related approach, using cross-modality imaging, can be used for producing SR hyperspectral (multi-spectral band) images. A low spatial resolution, hyperspectral image (LHI) and a high spatial resolution RGB image (Hrgb), can be optimally combined to produce a super resolution, hyperspectral image (SRHI). In this talk, I shall present new optimization methods based on low-rank or orthogonal tensor decompositions, and compare them with low-rank approximations of matricized representations of LHI and Hrgb. I shall also discuss variations stemming from different cross-modality imaging application (dynamic scene capture, facial and object recognition, cancer tissue histopathology) and where coupled optimization schemes for image registration and SR are necessary.

Data Center and Cloud Computing


Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet. It is basically a step up from Utility Computing and can be defined as a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform). Cloud Computing uses the Internet for communication and transport and provides hardware, software and networking services to clients. These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very simple graphical interface or API (Applications Programming Interface).

Design of efficient Data Centers has also been a topic of significant research from both academia and industry in the recent years. Efficient data centers are of prime importance as most of the modern businesses rely heavily on cloud services. Data centers also play a very important part in supporting and sustaining the fast growing web-based services and applications. They also form the backbone of most of the search engines, content hosting and distribution companies, social network platforms, tasks involving intense computation etc. Most of the networks have had to adapt and reconfigure and thus use the services offered by cloud computing and data centers to respond to the changing application demands and service requirements. Many large organizations like Microsoft and Google have their own cloud based services and boast of data centers with millions of servers.

The use of cloud computing services and applications is increasing rapidly due to the various advantages it brings and thus has led to the rise of vast cloud data centers. Both consumer and business applications are contributing to the growing dominance of cloud services. The exponential growth of Internet of Things (IoT) devices and applications would also expand the need for data centers to manage the large amounts of data and information that is collected and shared. A study by Cisco reveals that more than 94% of workloads and computation instances would need cloud services by 2021. The various advantages that the cloud based services and the data centers offer makes it the most viable option to choose for businesses and companies who plan to either secure their information or scale to newer levels.

Feature Engineering for Semi-supervised Machine Learning in Protein Informatics


Feature engineering, an integral data preprocessing step in machine learning, is aimed to boost the accuracy and efficiency of prediction systems. Those efforts principally rely on the creation of methods that imbibe facets of feature extraction, ranking, and selection methods cognizant of the underlying domain knowledge. This talk will emphasize the role of engineered evolutionary features using domain knowledge of hydrophobicity properties of proteins for enhanced prediction of their folding paradigm. Protein folding is frequently directed by local residue interactions that form clusters in the protein core. The interactions between residue clusters serve as potential nucleation sites in the folding process. Evidence postulates that the residue interactions are governed by the hydrophobic propensities that the residues possess. We will discuss a graph-theory-based machine learning framework to extract and isolate protein structural features that sustain invariance in evolutionary-related proteins feature ranking. The results obtained demonstrate that discriminatory residue interaction patterns obtained by these feature engineering methods are shared amongst proteins of the same family and can be effectively employed for both the structural and the functional annotation of proteins for multiple machine learning applications in bioinformatics.

Towards Semantic Adversarial Examples


Fueled by massive amounts of data, models produced by machine-learning (ML) algorithms, especially deep neural networks, are being used in diverse domains where trustworthiness is a concern, including automotive systems, finance, health care, natural language processing, and malware detection. Of particular concern is the use of ML algorithms in cyber-physical systems (CPS), such as self-driving cars and aviation, where an adversary can cause serious consequences.

However, existing approaches to generating adversarial examples and devising robust ML algorithms mostly ignore the semantics and context of the overall system containing the ML component. For example, in an autonomous vehicle using deep learning for perception, not every adversarial example for the neural network might lead to a harmful consequence. Moreover, one may want to prioritize the search for adversarial examples towards those that significantly modify the desired semantics of the overall system. Along the same lines, existing algorithms for constructing robust ML algorithms ignore the specification of the overall system. In this talk, we argue that the semantics and specification of the overall system has a crucial role to play in this line of research. We present preliminary research results that support this claim.
