UMBC’s Haibin Zhang shares tips to secure data in the cloud

UMBC’s Haibin Zhang shares tips to secure data in the cloud

As more consumers rely on cloud-based data storage for everything from family photos to financial information, both experts and general users have voiced concerns about cloud security. In a new Conversation article recently published by Scientific American, Haibin Zhang, assistant professor of computer science and electrical engineering, explains precautions consumers can take to protect their files in the cloud.

Zhang explains that data stored and secured using commercial cloud storage systems is encrypted, which means that without the key, the information looks like a series of meaningless characters. Encryption keys have the potential to be misused, if they end up in the wrong hands, which can compromise the security of files stored in a cloud.

“Just like regular keys, if someone else has them, they might be stolen or misused without the data owner knowing,” says Zhang. “And some services might have flaws in their security practices that leave users’ data vulnerable.”

Zhang notes that some cloud services allow customers to maintain their encryption key themselves, which give the consumer the control in ensuring that their data remains safe. Other services keep the encryption keys internally and manage the security for their customers. He says that while each option has benefits, it is important to recognize that “some services might have flaws in their security practices that leave users’ data vulnerable.”

To keep data secure in the cloud, Zhang suggests using enhanced security features offered by cloud storage companies and taking additional precautions that are available to individual customers. He recommends that people use a cloud storage service that allows customers to encrypt their data before uploading it for storage, and to rely on services that have been “validated by independent security researchers.”

Read “How secure is your data when it’s stored in the cloud?” in The Conversation for Zhang’s additional recommendations on securing data on the cloud. The piece also appeared in Scientific American, and has so far been read nearly 20,000 times.

Jennifer Sleeman receives AI for Earth grant from Microsoft

Jennifer Sleeman receives AI for Earth grant from Microsoft

Visiting Assistant Professor Jennifer Sleeman (Ph.D. ’17)  has been awarded a grant from Microsoft as part of its ‘AI for Earth’ program. Dr. Sleeman will use the grant to continue her research on developing algorithms to model how scientific disciplines such as climate change evolve and predict future trends by analyzing the text of articles and reports and the papers they cite.

AI for Earth is a Microsoft program aimed at empowering people and organizations to solve global environmental challenges by increasing access to AI tools and educational opportunities, while accelerating innovation. Via the Azure for Research AI for Earth award program, Microsoft provides selected researchers and organizations access to its cloud and AI computing resources to accelerate, improve and expand work on climate change, agriculture, biodiversity and/or water challenges.

UMBC is among the first grant recipients of AI for Earth, first launched in July 2017. The grant process was a competitive and selective process and was awarded in recognition of the potential of the work and power of AI to accelerate progress.

As part of her dissertation research, Dr. Sleeman developed algorithms using dynamic topic modeling to understand influence and predict future trends in a scientific discipline. She applied this to the field of climate change and used assessment reports of the Intergovernmental Panel on Climate Change (IPCC) and the papers they cite. Since 1990, an IPCC report has been published every five years that includes four separate volumes, each of which has many chapters. Each report cites tens of thousands of research papers, which comprise a correlated dataset of temporally grounded documents. Her custom dynamic topic modeling algorithm identified topics for both datasets and apply cross-domain analytics to identify the correlations between the IPCC chapters and their cited documents. The approach reveals both the influence of the cited research on the reports and how previous research citations have evolved over time.

Dr. Sleeman’s award is part of an inaugural set of 35 grants in more than ten countries for access to Microsoft Azure and AI technology platforms, services and training.  In an post on Monday, AI for Earth can be a game-changer for our planet, Microsoft announced its intent to put $50 million over five years into the program, enabling grant-making and educational trainings possible at a much larger scale.

CSEE Professor Marie desJardins interviewed for Voices in AI podcast

Voices in AI – Episode 20: A Conversation with Marie desJardins

Byron Reese interviewed UMBC CSEE Professor Marie desJardins as part of his Voices in AI podcast series on Gigaom. In the episode, they talk about the Turing test, Watson, autonomous vehicles, and language processing.  Visit the Voices in AI site to listen to the podcast and read the interview transcript.

Here’s the start of the wide-ranging, hour long interview.

Byron Reese: This is Voices in AI, brought to you by Gigaom. I’m Byron Reese. Today I’m excited that our guest is Marie des Jardins. She is an Associate Dean for Engineering and Information Technology as well as a professor of Computer Science at the University of Maryland, Baltimore County. She got her undergrad degree from Harvard, and a Ph.D. in computer science from Berkeley, and she’s been involved in the National Conference of the Association for the Advancement of Artificial Intelligence for over 12 years. Welcome to the show, Marie.

Marie des Jardins: Hi, it’s nice to be here.

I often open the show with “What is artificial intelligence?” because, interestingly, there’s no consensus definition of it, and I get a different kind of view of it from everybody. So I’ll start with that. What is artificial intelligence?

Sure. I’ve always thought about artificial intelligence as just a very broad term referring to trying to get computers to do things that we would consider intelligent if people did them. What’s interesting about that definition is it’s a moving target, because we change our opinions over time about what’s intelligent. As computers get better at doing things, they no longer seem that intelligent to us.

We use the word “intelligent,” too, and I’m not going to dwell on definitions, but what do you think intelligence is at its core?

So, it’s definitely hard to pin down, but I think of it as activities that human beings carry out, that we don’t know of lower order animals doing, other than some of the higher primates who can do things that seem intelligent to us. So intelligence involves intentionality, which means setting goals and making active plans to carry them out, and it involves learning over time and being able to react to situations differently based on experiences and knowledge that we’ve gained over time. The third part, I would argue, is that intelligence includes communication, so the ability to communicate with other beings, other intelligent agents, about your activities and goals.

Well, that’s really useful and specific. Let’s look at some of those things in detail a little bit. You mentioned intentionality. Do you think that intentionality is driven by consciousness? I mean, can you have intentionality without consciousness? Is consciousness therefore a requisite for intelligence?

I think that’s a really interesting question. I would decline to answer it mainly because I don’t think we ever can really know what consciousness is. We all have a sense of being conscious inside our own brains—at least I believe that. But of course, I’m only able to say anything meaningful about my own sense of consciousness. We just don’t have any way to measure consciousness or even really define what it is. So, there does seem to be this idea of self-awareness that we see in various kinds of animals—including humans—and that seems to be a precursor to what we call consciousness. But I think it’s awfully hard to define that term, and so I would be hesitant to put that as a prerequisite on intentionality.

talk: Ferraro on Understanding What We Read and Share, 1pm Fri 11/10, ITE325, UMBC

 

ACM Faculty Talk Series

Understanding What We Read and Share:
Event Processing from Text and Images

Dr. Frank Ferraro, Assistant Professor, CSEE
1:00-2:00pm Friday, 10 November 2017, ITE 325, UMBC

A goal of natural language processing (NLP) is to design machines with human-like communication and language understanding skills. NLP systems able to represent knowledge and synthesize domain-appropriate responses have the potential to improve many tasks and human-facing applications, like virtual assistants such as Google Now or question answering systems like IBM’s Watson.

In this talk, I will present some of my work—past, on-going, and future—in developing knowledge-aware NLP models. I will discuss how to better (1) encode linguistic- and cognitive science-backed meanings within learned word representations, (2) learn high-level representations for document and discourse understanding, and (3) how to generate compelling, human-like stories from sequences of images.

Frank Ferraro is an assistant professor in the CSEE department at UMBC. His research focuses on natural language processing, computational event semantics, and unlabeled, structured probabilistic modeling over very large corpora. He has published basic and applied research on a number of cross-disciplinary projects, and has papers in areas such as multimodal processing and information extraction, latent-variable syntactic methods and applications, and the induction and evaluation of frames and scripts.

Gymama Slaughter: The Art of Powering Implantable Electronics

The Art of Powering Implantable Electronics

UMBC professor Gymama Slaughter give a short talk at the Grit-X event on her recent research on powering implantable devices for medical applications.

The number of smart implantable devices is on the rise, especially as we approach the ramping up of the “internet of things.” A key challenge for implantable electronic devices has been keeping these devices properly and conveniently powered. Current battery technologies are sealed within these devices, thereby forcing the surgical replacement of the device once the battery is depleted. We need an inconspicuous means of powering implantable electronics with imperceptible methods that moves us toward new innovative solutions to the power challenge in implantable devices. A lightweight bio-solution that leverages the biochemical energy from human biological fluids is a step forward for powering these smart implantable technologies.

Marie desJardins receives award for inspiring women to pursue careers in computing, engineering and math

 

Professor Marie desJardins was selected for the 2017 A. Richard Newton Educator ABIE Award by the Anita Borg Institute. The annual award recognizes an educator who has developed innovative teaching practices and approaches that attract girls and women to computing, engineering, and math. As part of the award Dr. desJardins will take part in a panel on efforts to increase women’s representation and success in technology at the 2017 Grace Hopper Celebration of Women in Computing in Orlando this October.

Increasing gender diversity in computing has become both a professional focus and personal commitment for desJardins over the course of her career. “It’s part of a broader equity issue — for everyone to be able to envision themselves as creators of technology, and for the future of technology to be created by a diverse community of scientists and engineers,” she says.

This summer, desJardins shared her passion for encouraging girls and women to pursue careers in computing with nearly 150 elementary and middle school girls who attend the Mind, Body, Coding camp at UMBC. “Seeing these young girls whose lives could be transformed by greater access to computing is incredibly inspiring,” she says. “It’s a big part of what gets me energized every day to do the work that I do, from supporting diversity in K-12 computing education to mentoring junior female faculty who will train the next generation of computer scientists.”

The award announcement cited Professor desJardins for her many accomplishments in education, research and support of and commitment to improving student diversity, access, and quality of computer science courses at the high school level.

“Marie is known on campus and throughout her professional community for her dedication to mentoring, diversity, outreach, and innovative educational practices. Marie was named one of UMBC’s 10 “Professors Not to Miss” in 2011, and is regularly sought out to give invited talks to student groups.

UMBC researchers develop AI system to design clothing for your personal fashion style

 

AI system designs clothing for your personal fashion style

Everyone knows that more and more data is being collected about our everyday activities, like where we go online and in the physical world. Much of that data is being used for personalization. Recent UMBC CSEE Masters student Prutha Date explored a novel kind of personalization – creating clothing that matches your personal style.

Date developed a system that takes as input pictures of clothing in your closet, extracts a digitial representation of your style preferences, and then applies that style to new articles of clothing, like a picture pair of pants or a dress you find online. This work meshes well with recent efforts by Amazon to manufacture clothing on demand. Imagine being able to click on an article of clothing available online, personalize it to your style, and then have it made and shipped right to your door!

This innovative research was cited in a recent article in MIT Technology Review, Amazon Has Developed an AI Fashion Designer.

Tim Oates, a professor at the University of Maryland in Baltimore County, presented details of a system for transferring a particular style from one garment to another. He suggests that this approach might be used to conjure up new items of clothing from scratch. “You could train [an algorithm] on your closet, and then you could say here’s a jacket or a pair of pants, and I’d like to adapt it to my style,” Oates says.

Fashion designers probably shouldn’t fret just yet, though. Oates and other point out that it may be a long time before a machine can invent a fashion trend. “People innovate in areas like music, fashion, and cinema,” he says. “What we haven’t seen is a genuinely new music or fashion style that was generated by a computer and really resonated with people.”

You can read more about the work in a recent paper by Prutha Date, Ashwinkumar Ganesan and Tim Oates, Fashioning with Networks: Neural Style Transfer to Design Clothes. The paper describes how convolutional neural networks were used to personalize and generate new custom clothes based on a person’s preference and by learning their fashion choices from a limited set of clothes from their closet.

Prof. Gymama Slaughter to develop bioreactors for life-saving organ transplants

 

UMBC’s Gymama Slaughter to develop bioreactors that could pause the clock for life-saving organ transplants

UMBC’s Gymama Slaughter will develop a bioreactor to extend the viability of lifesaving human organs as they await transplant through a major new grant from the U.S. Army Medical Research and Material Command. Funding for the project totals nearly $1.5 million for a period of three years. Slaughter, associate professor of computer science and electrical engineering, will collaborate closely with Warren Grayson and Gerald Brandacher, both associate professors at Johns Hopkins.

Gymama Slaughter, right, with Joel Tyson ’17, chemical engineering, and Zahra Ghassemi M.S. ’17, chemical engineering, in her lab.

The team will create a bioreactor integrating in-line sensors, mechanical stimulator, and blood perfusion system to more accurately and continuously monitor organs as they are transported for transplantation. They will also “develop a system that closely mimic the organ’s natural environment,” explains Slaughter.

Currently, organ and tissue donors typically need to be in close proximity to transplant recipients due to limitations in organ transport. Some organs are only viable for about six hours, and they must be kept at very cool temperatures to remain viable, so the transport process can be a race against time. With technological improvements, Slaughter says, the viability of the organs could be increased to about 36 hours, greatly expanding the distance an organ could travel from donor to recipient, and the likelihood of a successful transplant.

“This interdisciplinary research will enable us to tackle complex organ transplant viability problems to create the next big breakthrough platform technology for extending and monitoring the viability of organs to improve patient care,” says Slaughter. Together, the researchers hope their work will lead to a new era of successful human organ transplantation, saving the lives of wounded soldiers and others in need of transplants in hard-to-reach locations around the world.
