# Practices of Weaving: Arts & Letters at MSU

Late last month, the faculty on the College Advisory Council (CAC) gave me a writing assignment. In preparation for our Fall 2017 faculty meeting on November 17, they asked me to take a step back from the updates on priorities, imperatives, and initiatives that have occupied our more recent faculty meetings, to articulate a broader vision of …

# Behold, the Super Cow

Hmm… how do they compute the Net Merit and GTPI? (But, but, what about all of that missing heritability?) See also Applied genomics: the genetic “super cow” Genomic prediction: no bull. Attention climate virtue signalers: more efficient cows produce less methane per liter of milk! Drink milk from genetically engineered cows :-) Tweet

# MSU Student Success Themes

It is incumbent on all of us who work at MSU to make sure we create realistic pathways so that our students from all backgrounds can meet the learning objectives the faculty have established for MSU programs. At MSU, we believe that all students whom we admit have the ability to learn, persist, and graduate …

# Benders Decomposition with Generic Callbacks

Brace yourself. This post is a bit long-winded (and arguably geekier than usual, which is saying something). Also, it involves CPLEX 12.8, which will not ship until some time next month. I have an updated version of an old example, solving a fixed charge transportation problem using Benders decomposition. The example (using Java, naturally) is …

# 23andme

I’m in Mountain View to give a talk at 23andMe. Their latest funding round was $250M on a (reported) valuation of$1.5B. If I just add up the Crunchbase numbers it looks like almost half a billion invested at this point… Slides: Genomic Prediction of Complex Traits Abstract: We apply methods from Compressed Sensing (L1-penalized regression; Donoho-Tanner …

# Review of ‘What’s Worth Teaching: Rethinking Curriculum in the Age of Technology’

I was recently asked to review with Charles Logan the book What’s Worth Teaching: Rethinking Curriculum in the Age of Technology by the incredible scholar Allan Collins. A link to the review and book on the Teachers College Record website here. A pre-print of our review is also available here.   Tweet

As I noted in yesterday’s post, one of the major changes associated with the new “generic” callback structure in CPLEX is that users now bear the responsibility of making their callbacks thread-safe. As I also noted yesterday, this is pretty new stuff for me. So I’m going to try to share what I know about thread …

# CPLEX 12.8: Generic Callbacks

IBM is getting ready to release CPLEX 12.8, and I had the opportunity to attend a presentation about by Xavier Nodet at the 2017 INFORMS annual meeting. Here are links to two presentations by Xavier: CPLEX Optimization Studio 12.8 – What’s New and CPLEX 12.8 – the Generic Callback. As with any new release, there …

# The Future is Here: Genomic Prediction in MIT Technology Review

MIT Technology Review reports on our startup Genomic Prediction. Some basic points worth clarifying: 1. GP’s first product, announced at the annual ASRM (American Society of Reproductive Medicine) meeting this week, tests chromosomal abnormality. It is a less expensive but more accurate version of existing tests. 2. The polygenic product, to be launched in 2018, checks …

# Time fleas, with apologies to Jonathan Swift

Over on twitter, Kyle Card posted a photo of Halloween in the Lenski lab. That prompted Morgan Feeney to reply: “You mean you don’t all dress up as different generations of the LTEE? I am SHOCKED.” And that got me thinking about Jonathan Swift’s rhapsody on fleas: So nat’ralists observe, a flea Has smaller fleas that on him prey; And these have …

# What “R” qualitative research methods?

I recently stumbled upon a post on R-bloggers entitled “Qualitative Research in R.” This title got me pretty excited, since I’m generally excited about most things R and since I recently helped teach a qualitative methods course, which has had me thinking about adding more ethnographic and other qualitative elements to my work. I’d also heard of …

# Two data packages: Rail-trails and an assessment of student achievement

Because of interest and the need for better examples (for teaching and for use in tools under development, such as prcr and tidyLPA, I worked to create two data packages, data easily available through an R package. A benefit of the data being in an R package is that it is even easier to access than other formats (in R): …

# AlphaGo Zero: algorithms over data and compute

AlphaGo Zero was trained entirely through self-play — no data from human play was used. The resulting program is the strongest Go player ever by a large margin, and is extremely efficient in its use of compute (running on only 4 TPUs). Previous versions of AlphaGo initially trained on thousands of human amateur and professional games …

# Practicing Gratitude

Last weekend was homecoming on the Michigan State University campus, and I found myself reflecting on the meaning and significance of gratitude. So many alumni returned to campus to give thanks for all the ways MSU set them on a meaningful path. In the College of Arts & Letters, we celebrated the generous gifts we received from …

# Pictures worth thousands of words

The use of whiteboard presentations, especially for short presentations  seems very useful in getting the gyst of a speaker’s intent. Even more so than Powerpoint presentations. I first stumbled on one a few years ago when Sir Kenneth Robinson condense a longer speech into an 11 minute whiteboard presentation that was just brilliant!! When I …

# The Philosophers’ Way

Sometimes we forget … forget to take a break, forget to get outside, and forget to reflect on our individual and collective pasts. After an intense three days of talks at EMBO—hearing about exciting work by diverse and superb biologists in 13-minute chunks (plus Q&A); seeing dear friends Santiago Elena, Sebastian Bonhoeffer, and Roy Kishony; …

# Steven Weinberg: What’s the matter with quantum mechanics?

In this public lecture Weinberg explains the problems with the two predominant interpretations of quantum mechanics, which he refers to as Instrumentalist (e.g., Copenhagen) and Realist (e.g., Many Worlds). The term “interpretation” may be misleading because what is ultimately at stake is the nature of physical reality. Both interpretations have serious problems, but the problem …

# Survival of the Steepest

Most textbooks tell you that the evolutionary process is really quite simple: three rules are all that’s necessary: inheritance, variation, and selection. It is indeed true that these three rules are all that’s needed for evolution to occur, but that does not mean that the evolutionary process is simple. In fact, quite the opposite. Real systems evolve in …

# Guns, More Guns – Will We Ever Have Enough?

We were away in Britain when news of the horrific massacre in Las Vegas occurred. We were actually approached on the street in the small Cornish town of Fowey by an older fellow who overheard us chatting and noted our North American accent. He wanted us to try and explain to him how it is …

# Blade Runner 2049: Demis Hassabis (Deep Mind) interviews director Villeneuve

Hassabis refers to AI in the original Blade Runner, but it is apparent from the sequel that replicants are merely genetically engineered humans. AI appears in Blade Runner 2049 in the form of Joi. There seems to be widespread confusion, including in the movie itself, about whether to think about replicants as robots (i.e., hardware) …

# Information Theory of Deep Neural Nets: “Information Bottleneck”

This talk discusses, in terms of information theory, how the hidden layers of a deep neural net (thought of as a Markov chain) create a compressed (coarse grained) representation of the input information. To date the success of neural networks has been a mainly empirical phenomenon, lacking a theoretical framework that explains how and why …

# Copyright, Fair Use, and Creative Commons in 7 more videos

Last year, I wrote a post about a series of YouTube videos that I used to give a guest lecture on copyright, fair use, and Creative Commons. It went well enough that I was asked to come back this year and guest lecture again. I made some tweaks to the presentation this time around, switching the order …

# Where are participants in American and Canadian teacher hashtags?

My dissertation research is focused on Regional Educational Twitter Hashtags (RETHs), which are teacher-focused hashtags that are associated with particular geographic regions, such as American states or Canadian provinces or territories. This isn’t the first time that I’ve done a project on this phenomenon, and it’s rewarding to come back to RETHs to answer some questions that …

# Sport and Social Justice in South Africa

Nelson Mandela would have been proud of Colin Kaepernick and the black (as well as a few white) U.S. athletes involved in the national anthem demonstrations against police violence and systemic racism. “Sport has the power to change the world,” Mandela believed. “It has the power to inspire. It has the power to unite people in a way that …

# How Do Michiganders Feel About a Tax Cut? It Depends On What They Know

In March 2017, the Michigan House of Representatives narrowly voted down a proposal to reduce the income tax. But the issue of tax cuts continues to be discussed, both at the state and federal level. To gauge citizen opinions about tax cuts, MSU’s State of the State Survey asked Michigan residents questions about the proposed tax cut …

# A Gentle Introduction to Neural Networks

“A gentle introduction to the principles behind neural networks, including backpropagation. Rated G for general audiences.” This very well done. If you have a quantitative background you can watch it at 1.5x or 2x speed, I think :-) A bit more on the history of backpropagation and convexity: why is the error function convex, or nearly …

# Getting started with ‘open science’ through blogging

Through a few different projects and people (such as SIPS and rOpenSci and conversations with friends / colleagues both online and offline), I have been exposed to the idea of open science. I’m actually going to punt for the moment. Here’s a definition that sounds about right to me: Open science is the movement to make scientific research, data and dissemination accessible …

# A person-in-context approach to student engagement in science (article in JRST)

Over the past few years, I have worked with Jennifer Schmidt and Patrick Beymer to explore student engagement in science using the Experience Sampling Method (ESM). Most recently, we used what scholars have referred to as a “person-in-context” approach, using both ESM and a person-oriented approach. A figure is helpful for conveying how the person-oriented approach can be used to …

# Feynman, Schwinger, and Psychometrics

Slate Star Codex has a new post entitled Against Individual IQ Worries. I write a lot about the importance of IQ research, and I try to debunk pseudoscientific claims that IQ “isn’t real” or “doesn’t matter” or “just shows how well you do on a test”. IQ is one of the best-studied ideas in psychology, one …

# The Vietnam War, Ken Burns and Lynn Novick

Ken Burns’ Vietnam documentary is incredibly good. Possibly the best documentary I’ve ever seen. It’s heartbreaking tragedy, with perspectives from all sides of the conflict: Americans and North and South Vietnamese, soldiers from both sides, war protestors, war planners, families of sons and daughters who died in the war. I was a child when the …

# Is there such a thing as “white hat” research ethics violations?

A couple of weeks ago, I posted about some of the ethical dilemmas involved in using public data for research, using an example of facial recognition researchers who used YouTube videos of people undergoing hormone replacement therapy to improve their algorithms’ ability to recognize faces from pre- and post-transition. Since reading that article, I’ve seen the occasional …

# Minimizing a Median

$$\def\xorder#1{x_{\left(#1\right)}} \def\xset{\mathbb{X}} \def\xvec{\mathbf{x}}$$A somewhat odd (to me) question was asked on a forum recently. Assume that you have continuous variables $$x_{1},\dots,x_{N}$$ that are subject to some constraints. For simplicity, I’ll just write $$\xvec=(x_{1},\dots,x_{N})\in\xset$$. I’m going to assume that $$\xset$$ is compact, and so in particular the $$x_{i}$$ are bounded. The questioner wanted to …

# Some thoughts on starting year 5 (and French comics)

The image below, from the French comic book Carnets de thèse (“thesis notes”), has been on my mind as I begin my fifth year of grad school. I bought Carnets de thèse as a present for myself for my last birthday, expecting it to be an educational glimpse into the French grad school experience and …

# Comparing MPLUS and MCLUST output

Introduction At present, MPlus is a widely-used tool to carry out Latent Profile Analysis, and there does not seem to be a widely-accepted or used way to carry out Latent Profile Analysis in R. This compares output from MPlus to output from the R package MCLUST, which is accessed through the package tidymixmod which I …

# “Helicopter parents produce bubble wrapped kids”

Heterodox Academy. In my opinion these are reasonable center-left (Haidt characterizes himself as “liberal left”) people whose views would have been completely acceptable on campus just 10 or 20 years ago. Today they are under attack for standing up for freedom of speech and diversity of thought. Tweet

# Public data and digital research ethics

The Verge recently posted an article that highlights some of the ethical dilemmas involved in collecting publicly-available data for research purposes. The article begins by describing the work of a researcher working on facial recognition of people before and after hormone replacement therapy: On YouTube, he found a treasure trove. Individuals undergoing HRT often document their progress …

# Varieties of Snowflakes

I was pleasantly surprised that New Yorker editor David Remnick and Berkeley law professor Melissa Murray continue to support the First Amendment, even if some of her students do not. Remnick gives Historian Mark Bray (author of Antifa: The Anti-Fascist Handbook) a tough time about the role of violence in political movements. After Charlottesville, the Limits …

# How to be an effective acting director, chair or dean — Part II (essay)

Last week, Inside Higher Ed published an essay of mine describing my experience as an interim dean. It covered several practical, task-oriented topics: identifying one’s core mission for the interim period, allaying colleagues’ fears, acquiring reliable information and triaging the issues that land in your inbox. But leading a college that includes a department of theater helped me recognize …

# BENEFICIAL AI 2017 (Asilomar meeting)

AI researcher Yoshua Bengio gives a nice overview of recent progress in Deep Learning, and provides some perspective on challenges that must be overcome to achieve AGI (i.e., human-level general intelligence). I agree with Bengio that the goal is farther than the recent wave of excitement might lead one to believe. There were many other …

# Using notebooks for beginning-of-semester planning

One of the first posts I published to this blog was a lament that I just couldn’t get notebooks to work for me. About a year ago, though, I finally found a routine that got notebooks working for me. I started off working my way through two copies of a Self Journal before borrowing some …
