Three talks on statistics and neuroscience by Rob Kass
Robert E. Kass
Professor, Department of Statistics and Machine Learning Department
Interim Co-Director, Center for the Neural Basis of Cognition
Carnegie Mellon University
Monday, April 11, 4:00 p.m., UMass, 16th floor of Lederle Graduate Research Tower Room 1634, Amherst, MA
Title: Statistics and Bayesian Inference in Neuroscience
Abstract: Experimenters are typically adept at applying standard statistical techniques, while computational neuroscientists are capable of formulating mathematically sophisticated data analytic methods to attack novel problems in data analysis. Yet, in many situations, statisticians proceed differently than those without formal training in statistics. What is different about the the way statisticians approach problems? I will give you my thoughts on this subject, and will illustrate with examples, including a new extension of Bayesian control of false discoveries, applied to neural synchrony detection across a network of interacting spiking neurons. I will conclude with some related comments on scientific reproducibility, illustrating them with an experiment in which brain signals were used to run a robotic device.
Tuesday, April 12, 12:10 p.m., McConnell Auditorium, Smith College, Northampton, MA
Title: Statistical Ideas in Neuroscience
Abstract: The brain sciences seek to discover mechanisms by which neural activity is generated, thoughts are created, and behavior is produced. Major advances have been based on careful consideration of data, which often involves statistics, especially when the phenomenon involves subtle variations in the signal, relative to noise. In addition, since the beginnings of neuroscience, it has proven useful to describe many aspects of brain activity by incorporating ideas from statistics. I will review these points in the context of visual perception, and will include a popular theory of what might be going on in the brain when we "pay attention to" a visual stimulus. I will also make some comments on scientific reproducibility, illustrating them with an experiment in which brain signals were used to run a robotic device.
Tuesday, April 12, 4:00 p.m., Adele Simmons Hall Room 112, Hampshire College
Title: Neuroscience in the Age of Big Data
Abstract: New technologies are creating exciting opportunities in neuroscience, but they are also posing new Big Data analytic challenges. Successful solutions will combine high-powered computational algorithms together with fundamental statistical principles for taming the inherently variability in brain-based data. One of the major approaches to Big Data, the Bayesian approach, is also relevant to neuroscience from a theoretical perspective because it helps capture the idea that evolution has driven the brain to perform optimally. I will review these points, focusing especially on visual perception, and will include a popular notion of what might be going on in the brain when we "pay attention," as in paying attention to a visual stimulus. I will also make some comments on scientific reproducibility, illustrating them with an experiment in which brain signals were used to run a robotic device.

Protein Data Analysis at Scale
Aaron Coburn, Amherst College
Monday, February 22nd, 4:30pm, Amherst College, Seeley Mudd 206 (refreshments at 4:00pm in Seeley Mudd 208)
Abstract:The R programming environment is used by researchers and students alike to perform all manner of statistical analysis. This talk will describe a project at Amherst College that is using R to simulate and analyze protein structure perturbation, an area of study that has wide ranging implications for many branches of medical research. While writing the code for these simulations in R is relatively straight forward, running the code on a single machine can be prohibitively time consuming. In this situation, the typical approach is to rewrite the software so that it can be deployed on a Hadoop- or MPI-based cluster.
With this project, we took a different approach and used Spark, one of the newer distributed computational platforms. The primary advantage of Spark in this case is its tight integration with R execution environment, meaning the R code did not need to be substantially changed in order to run across a cluster of worker machines. Using the protein simulation project as a case study, this talk will explore how Spark allows data scientists to make use of existing R-based code both to explore very large datasets and run highly parallelized computations.

Abstract: The human genome project in conjunction with the rapid advance of high throughput technology has transformed the landscape of health science research. The genetic and genomic era provides an unprecedented promise of understanding genetic underpinnings of complex diseases or traits, studying gene-environment interactions, predicting disease risk, and improving prevention and intervention, and advancing precision medicine. A large number of genome-wide association studies conducted in the last ten years have identified over 1,000 common genetic variants that are associated with many complex diseases and traits. Massive targeted, whole exome and whole genome sequencing data as well as different types of -omics data have become rapidly available in the last few years. These massive genetic and genomic data present many exciting opportunities as well as challenges in data analysis and result interpretation. They also call for more interdisciplinary knowledge and research, e.g., in statistics, machine learning, data curation, molecular biology, genetic epidemiology and clinical science. In this talk, I will discuss analysis strategies for some of these challenges, including rare variant analysis of whole-genome sequencing association studies; analysis of multiple phenotypes (pleiotropy), and integrative analysis of different types of genetic and genomic data.

Statistics and Policy Making: The Case of Greece
Andreas Georgiou, Former Head of Greek Statistics Office
Wednesday, November 11, 8:00 p.m., Amherst College, Converse Hall, Cole Assembly Room
Abstract: The talk will focus on the importance of statistics in effective policy making and good governance and will relate his five years of working as the head of the Greek Statistical Office. In 2010, Georgiou was appointed the head of the Greek Office, after serving as an economist for 21 years at the IMF. His discoveries regarding the Greek deficit led him to the center of a political firestorm that included personal felony charges that could have led to a life in prison and enormous fines. Amherst College Converse Hall, Cole Assembly Room, 8 p.m.

Colloqium on "Causal inference: identifying subgroups by their response to treatment”
Sarah Anoke, Department of Biostatistics, Harvard T.H. Chan School of Public Health
Thursday, October 22, 4:30 p.m., Amherst College, Seeley Mudd 206
Abstract: Causal inference is a field of statistics focused on measuring a particular type of relationship between two variables. Referring to these two variables as the `treatment’ and the `outcome’, we consider the value that an individual’s outcome would take if the treatment was present, and the value that the individual’s outcome would take if the treatment was absent. The difference in these two potential outcomes is the treatment effect. Every individual has their own individual treatment effect (ITE). But because only one of these two potential outcomes is observable, ITEs cannot be estimated from observed data. To overcome this problem, the average outcome among a group of individuals unexposed to treatment is subtracted from the average outcome among a group of individuals exposed to treatment, yielding an average treatment effect (ATE). It is of interest to identify subgroups for which the subgroup-specific ATE is very different from the overall ATE. Knowing the overall ATE is arguably misleading; we would prefer to know that the drug has no effect within women but a dramatic effect within men. How then, can the data tell us which subgroups respond particularly well or poorly to treatment, without advance knowledge of these subgroups?
Colloqium on "Statistical tools and challenges for monitoring migratory birds”
Emily Silverman, Statistician, Division of Migratory Bird Management, U.S. Fish & Wildlife Service
Friday, October 30th, 2015 2:00 p.m., Amherst College, Frost Library 211
Abstract: Federal management of migratory birds began 100 years ago, when the United States signed the 1916 Convention for the Protection of Migratory Birds with Great Britain (for Canada). These protections were codified in the Migratory Bird Treaty Act (MBTA) of 1918, which now covers over 800 species of birds, and stands as one of the earliest U.S. environmental laws. The evolution of management approaches since the MBTA has led to the development of monitoring programs and quantitative methods in wildlife science. I will present the history of bird monitoring and statistical methods for population assessment and will discuss new approaches, challenges, and how a solid understanding of statistical concepts is essential for informed management. Drawing on examples from my own work, I will highlight the interdisciplinary skills needed to operate effectively as a scientist and statistician in a resource management agency. As our ability to collect information about the natural world expands in an increasingly digital world, the need for innovative, technically-adept wildlife scientists is expanding.

- Taylor Arnold, PhD of AT&T Labs will talk on: Oh the Places You'll Go: The Surprising Complexity of Statistics' Most Basic Model. Abstract: A Bernoulli distribution describes a process which has only two outcomes. Despite the simplicity, it is used in a wide array of applications including a simple coin toss, the outcome of a sporting event, weather models, and the winner of an election. A careful analysis of the Bernoulli distribution also raises a number of theoretical questions leading to topics such as Bayesian inference, minimaxity and estimator theory. Fortunately, the relatively uncomplicated nature of the Bernoulli model allows such questions to be studied without the advanced mathematical machinery required for a more general treatment. This talk will explore these practical and theoretical considerations, with a focus towards the `big questions' which continue to guide modern statistical research. Two real datasets, from baseball and medicine, will be used throughout to guide the discussion.
