ACSHF Forum Monday

Beth Veinott

An Applied Cognitive Science and Human Factors (ACSHF) Forum will take place at 2 p.m. Monday (Nov. 11) in Meese 109. Beth Veinott (CLS), will present “Improving Forecasts and Plans: Evaluating the Effect of Counterfactual Reasoning in a Structured Analytic Technique.”

One challenge affecting a variety of teams, such as software development, engineering, military, and crisis management, is overconfidence in the effectiveness of their plans.  Referred to as the planning fallacy, Buehler et al. (1994) suggests that ignoring past failures is a key cognitive element in this phenomenon. This talk summarizes recent experiments examinin the effect of counterfactual reasoning strategies, thinking about what might have happened under different circumstances, on people’s reasons, confidence and predictions.

Leveraging a collaborative, structured analytic technique called the Premortem, this project extends research on counterfactual reasoning to estimates in planning. The results will be discussed in the context of advances in machine learning, AI, and crowdsourcing that have changed the information available to teams.

“The Bit Player,” a documentary about Claude Shannon, Is Sunday, November 3

The College of Computing, the Institute of Computing and Cybersystems, and the Department of Electrical and Computer Engineering are sponsors of a showing of the film, “The Bit Player,” during this week’s 41 North Film Festival at the Rozsa Center. The showing is this Sunday, November 3, at 3:30 pm. There is no charge to attend, but film-goers are encouraged to secure tickets online and at the Rozsa Center box office. (mtu.edu/rozsa/ticket/calendar/)
“The Bit Player” is a documentary about  Claude Shannon, the father of information theory and a hero to many in electrical engineering, computer engineering, and computer science. Claude Shannon was born in Gaylord, Michigan, on April 30, 1916. He attended University of Michigan, double majoring in mathematics and electrical engineering. His MIT master’s thesis was titled, “A Symbolic Analysis of Relay and Switching Circuits,” which related electric circuits and their on/off character to Boolean Algebra, the “Mathematics of Logical Thought,” laying the foundation for machines to make decisions — “to think.”
This was the first documentary film funded by the IEEE Foundation, and it was done in conjunction with the IEEE Information Theory Society (ITS). The ITS is the only IEEE society whose “basis” has a definitive starting date – the 1948 publication of Shannon’s A Mathematical Theory of Communication <http://math.harvard.edu/~ctm/home/text/others/shannon/entropy/entropy.pdf>

Claude Shannon

A description from the film’s official website https://thebitplayer.com): “In a blockbuster paper in 1948, Claude Shannon introduced the notion of a “bit” and laid the foundation for the information age. His ideas ripple through nearly every aspect of modern life, influencing such diverse fields as communication, computing, cryptography, neuroscience, artificial intelligence, cosmology, linguistics, and genetics. But when interviewed in the 1980s, Shannon was more interested in showing off the gadgets he’d constructed — juggling robots, a Rubik’s Cube solving machine, a wearable computer to win at roulette, a unicycle without pedals, a flame-throwing trumpet — than rehashing the past. Mixing contemporary interviews, archival film, animation and dialogue drawn from interviews conducted with Shannon himself, The Bit Player tells the story of an overlooked genius who revolutionized the world, but never lost his childlike curiosity.”

Anna Little to Present Talk October 18, 1 p.m.

Anna Little

Dr. Anna Little, a postdoc in the Department of Computational Mathematics, Science, and Engineering at Michigan State University, will present her talk, “Robust Statistical Procedures for Clustering in High Dimensions,” on Friday, October 18, 2019, at 1:00 p.m., in Fisher Hall Room 327B.

Dr. Little completed a PhD in mathematics at Duke University in 2011. She has been at Michigan State since 2018.  Visit her website at www.anna-little.com.

Lecture Abstract: This talk addresses multiple topics related to robust statistical procedures for clustering in high dimensions, including path-based spectral clustering (a new method), classical multidimensional scaling (an old method), and clustering in signal processing. Path-based spectral clustering is a novel approach which combines a data driven metric with graph-based clustering. Using a data driven metric allows for fast algorithms and strong theoretical guarantees when clusters concentrate around low-dimensional sets.

Another approach to high-dimensional clustering is classical multidimensional scaling (CMDS), a dimension reduction technique widely popular across disciplines due to its simplicity and generality. CMDS followed by a simple clustering algorithm can exactly recover all cluster labels with high probability when the signal to noise ratio is high enough. However, scaling conditions become increasingly restrictive as the ambient dimension increases, illustrating the need for robust unbiasing procedures in high dimensions.  Clustering in signal
processing is the final topic; in this context each data point corresponds to a corrupted signal. The classic multireference alignment problem is generalized to include random dilation in addition to random translation and additive noise, and a wavelet based approach is used to define an unbiased representation of the target signal(s) which is robust to high frequency perturbations.
