From 1ea9be57861568dbcc8b9595fac6c346f63fa35d Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 10 May 2026 02:36:18 +0000 Subject: [PATCH 01/32] phase 1: add Gemfile pinned to github-pages for reproducible local builds Adds the standard github-pages meta-gem so contributors can run bundle install && bundle exec jekyll serve locally and get the same Jekyll version GitHub Pages uses for the live build. Removes the Gemfile/Gemfile.lock entries from .gitignore that were blocking this. --- .gitignore | 2 -- Gemfile | 5 +++++ 2 files changed, 5 insertions(+), 2 deletions(-) create mode 100644 Gemfile diff --git a/.gitignore b/.gitignore index 3c7baf4..1dfdf89 100644 --- a/.gitignore +++ b/.gitignore @@ -1,5 +1,3 @@ _site/ .sass-cache/ -Gemfile -Gemfile.lock **/.DS_Store diff --git a/Gemfile b/Gemfile new file mode 100644 index 0000000..e1bc0c3 --- /dev/null +++ b/Gemfile @@ -0,0 +1,5 @@ +source "https://rubygems.org" + +# GitHub Pages pins all gem versions used by the live build, so installing +# this locally gives a reproducible preview that matches production. +gem "github-pages", group: :jekyll_plugins From b956cd528d6840d0df4f8418bae5b24bab2e4903 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 10 May 2026 02:37:24 +0000 Subject: [PATCH 02/32] phase 1: add pre-commit config with image compression hooks Adds .pre-commit-config.yaml wiring three local hooks: - jpegoptim with --max=85 for lossy JPEG compression - oxipng -o 4 for lossless PNG optimization - svgo for SVG minification All run as language: system so contributors install the binaries once (via apt/brew/cargo/npm) rather than pre-commit rebuilding them per repo.

If a contributor skipped the local hook install, the workflow fails with a diff showing what should have been compressed/normalized. Contributors then run pre-commit run --all-files locally and commit the fixes. Installs jpegoptim (apt), oxipng (cargo), and svgo (npm) so the hooks have the same tooling locally and in CI. --- .github/workflows/pre-commit.yml | 36 ++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 .github/workflows/pre-commit.yml diff --git a/.github/workflows/pre-commit.yml b/.github/workflows/pre-commit.yml new file mode 100644 index 0000000..4901778 --- /dev/null +++ b/.github/workflows/pre-commit.yml @@ -0,0 +1,36 @@ +name: pre-commit + +on: + pull_request: + push: + branches: [master] + +jobs: + pre-commit: + runs-on: ubuntu-latest + + steps: + - name: Checkout repository + uses: actions/checkout@v4 + + - name: Set up Python + uses: actions/setup-python@v5 + with: + python-version: '3.11' + + - name: Install pre-commit + run: pip install pre-commit + + - name: Install image tooling (jpegoptim, oxipng, svgo) + run: | + sudo apt-get update + sudo apt-get install -y jpegoptim + cargo install oxipng --locked + npm install -g svgo + + - name: Run pre-commit + # Pre-commit's default behavior: any hook that modifies files exits + # nonzero.

From a12c4508aaeb95639662604e68ba1000bf01e41a Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 10 May 2026 02:43:36 +0000 Subject: [PATCH 09/32] phase 4: add code-quality hooks (baseline + yamllint + markdownlint) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds three new pre-commit repos: - pre-commit/pre-commit-hooks: trailing-whitespace, end-of-file-fixer, check-yaml/json, check-merge-conflict, mixed-line-ending, check-added-large-files (1 MB generic cap), detect-private-key - adrienverge/yamllint: YAML style checks scoped to _data/, _config.yml. Configured via .yamllint extending the relaxed profile and disabling document-start, line-length (data files have long values), and loosening indentation to allow the existing block-sequence style. - igorshubovych/markdownlint-cli with --fix: auto-fixes trailing-space, blanks-around-headings, multiple-blanks, list/HR formatting, etc. Configured via .markdownlint.json disabling MD013 (line length), MD033 (inline HTML — Jekyll posts use it), and a few rules that conflict with existing legacy content (MD001 heading increment, MD025 single H1, MD034 bare URLs, MD036 emphasis-as-heading, MD041 first-line-h1, MD045 no-alt-text, MD059 descriptive-link-text). The disabled rules represent a "loose baseline" that can be tightened in a follow-up content-cleanup pass. The next commit will be the one-shot first-run normalization. --- .markdownlint.json | 12 ++++++++++++ .pre-commit-config.yaml | 26 ++++++++++++++++++++++++++ .yamllint | 15 +++++++++++++++ 3 files changed, 53 insertions(+) create mode 100644 .markdownlint.json create mode 100644 .yamllint diff --git a/.markdownlint.json b/.markdownlint.json new file mode 100644 index 0000000..249f7a0 --- /dev/null +++ b/.markdownlint.json @@ -0,0 +1,12 @@ +{ + "default": true, + "MD001": false, + "MD013": false, + "MD025": false, + "MD033": false, + "MD034": false, + "MD036": false, + "MD041": false, + "MD045": false, + "MD059": false +} diff --git a/.pre-commit-config.yaml b/.pre-commit-config.yaml index 0b11c42..eb4e830 100644 --- a/.pre-commit-config.yaml +++ b/.pre-commit-config.yaml @@ -28,3 +28,29 @@ repos: entry: python3 scripts/check_image_size.py language: system types_or: [image, svg] + + - repo: https://github.com/pre-commit/pre-commit-hooks + rev: v6.0.0 + hooks: + - id: trailing-whitespace + - id: end-of-file-fixer + - id: check-yaml + - id: check-json + - id: check-merge-conflict + - id: mixed-line-ending + args: [--fix=lf] + - id: check-added-large-files + args: [--maxkb=1000] + - id: detect-private-key + + - repo: https://github.com/adrienverge/yamllint + rev: v1.38.0 + hooks: + - id: yamllint + args: [--strict] + + - repo: https://github.com/igorshubovych/markdownlint-cli + rev: v0.48.0 + hooks: + - id: markdownlint + args: [--fix] diff --git a/.yamllint b/.yamllint new file mode 100644 index 0000000..2790a05 --- /dev/null +++ b/.yamllint @@ -0,0 +1,15 @@ +# yamllint configuration.

Python is used for scripting, building and scraping websites, and pretty much anything else where performance isn't critical. It is also the *de facto* standard in data science and machine learning. It's also comparatively easy to learn. Python is the new BASIC. What's more, Python skills actually help on a resume.

Matlab is pervasive in neuroscience and engineering, and it provides a decent ecosystem (professionally supported toolboxes, a decent IDE and debugger) out of the box.

If you're coming to Python from a different language and want a quick overview, I highly recommend Jake Vanderplas's [Whirlwind Tour of Python](https://jakevdp.github.io/WhirlwindTourOfPython/). It's perhaps a little more than what many scientists need to know to get started, but it's free and excellent. ## In addition + - For Python, once you've gotten a basic acquaintance with the language, and after you've worked on your [scientific programming](#python-for-data-science) skills, it's worth going back to invest in more advanced aspects of the language. This pays dividends both in understanding others' code and in writing reusable libraries of your own. For Python, I particularly recommend [Fluent Python](http://shop.oreilly.com/product/0636920032519.do). # Python for Data Science + Most programming material online is targeted either at students learning their first programming language or professionals learning a new tool for software development. However, programming for science — writing code that runs, simulates, or analyzes experiments — carries its own set of unique challenges, and is distinct from general-purpose programming. That's why learning to program Python is distinct from learning "scientific Python," the suite of packages, tools, and practices that surround Python as used in (data) science. This is why I make every new student in my lab read (cover-to-cover) Jake Vanderplas's [Python Data Science Handbook](https://jakevdp.github.io/PythonDataScienceHandbook/). The book covers exactly the toolset we use: IPython, Jupyter, NumPy, SciPy, Pandas, Matplotlib, and Scikit-Learn. I don't know of a better, more comprehensive introduction to modern scientific Python. # Statistics + **Professional disclaimer:** I recommend a good grounding in statistical theory. It's worth the investment. But we're all busy people. What I usually end up recommending to students: + - [Data Analysis Using Regression and Multilevel/Hierarchical Models](http://www.stat.columbia.edu/~gelman/arm/). This was my first introduction to applied Bayesian analysis. Surprisingly readable for students without much statistical background and teaches an approach to modeling data that I like and advocate. As a bonus, covers Markov Chain Monte Carlo sampling tools like [Stan](http://mc-stan.org/) that are necessary in practice. - [A First Course in Bayesian Statistical Methods](https://www.stat.washington.edu/people/pdhoff/book.php). This is the book they use for the intro Bayesian class at Duke. This is really for students who are investing in serious stats education. Finishing this one may not leave you quite ready to tackle your real data, but you will have a solid foundation to build on. - [All of Statistics](https://www.amazon.com/All-Statistics-Statistical-Inference-Springer/dp/0387402721/ref=sr_1_1?ie=UTF8&qid=1249141007&sr=8-1). A really nice single-volume introduction to statistics. A bit of a steep learning curve for the less mathematically inclined, but worth a mention. - For Duke students interested in the problem of actually implementing statistical models and methods in code, I highly recommend Cliburn Chan's [STA 663](https://github.com/cliburn/sta-663-2021), typically offered each spring. Teaches all the same software tools my lab uses. # Machine Learning: Classic + There are lots of great references. The current deep learning phase notwithstanding, machine learning is actually a very broad field, and what is old now will eventually be new again. Some references worth checking out: + - [An Introduction to Statistical Learning](https://www.statlearning.com) - [Elements of Statistical Learning](http://web.stanford.edu/~hastie/ElemStatLearn/) (free pdf) - [Pattern Recognition and Machine Learning](https://www.springer.com/us/book/9780387310732) ([pdf](http://users.isr.ist.utl.pt/~wurmd/Livros/school/Bishop%20-%20Pattern%20Recognition%20And%20Machine%20Learning%20-%20Springer%20%202006.pdf)) - [Machine Learning: A Probabilistic Perspective](https://probml.github.io/pml-book/) (Duke uses this for its intro ML class) - - # Machine Learning: Deep Learning + So Deep Learning (aka neural networks) is eating the world. Briefly: + - Read the [Deep Learning Book](http://www.deeplearningbook.org/). It's even free online from the website. The field is moving incredibly rapidly, but this is now the standard introduction. - For online classes, we've had students take the [Stanford convnets class](http://cs231n.stanford.edu/) and Coursera's [Deep Learning Specialization](https://www.coursera.org/specializations/deep-learning). These are pretty basic but nice for people getting started.[^online_dl_classes] - Over the last few years, we've gradually moved from [TensorFlow](https://www.tensorflow.org/) to [PyTorch](https://pytorch.org/) and [JAX](https://github.com/google/jax). This mirrors broader trends among machine learning researchers, since the latter often allow for faster prototyping. # Notes - [^sof_os]: Note that information on StackOverflow tends to be proportional to the popularity of a given tool. So information on R and Python is extensive, while Matlab has comparatively less support. [^matlab_woes]: To be fair, Matlab is now an old language and was designed to ease the burden of engineers who were coding C and FORTRAN for a living. By those standards, it is highly successful, and new features are being added to the language all the time. [^online_dl_classes]: Keep in mind that these classes are great at introducing the material, but they tend to be very light on theory and more focused on simple applications. While they're a great starting point for high school students, undergraduates, or graduate students in other fields, students interested in machine learning research will be expected to engage with these ideas at a much higher mathematical level. diff --git a/location.md b/location.md index 40ed342..859a4c8 100644 --- a/location.md +++ b/location.md @@ -4,7 +4,7 @@ title: How to find us # header at the top of the page nav: Find Us # what shows up in the navbar at the top (do not define if you don't want page in the navbar) --- -We're located in the [Bryan Research Building](https://maps.duke.edu/?focus=68).

One answer, proposed by Horace Barlow half a century ago, is that the nervous system attempts to minimize redundancy, maximizing mutual information between the world and the brain's representation of it while minimizing metabolic costs. This theory makes a number of testable predictions, including the well-known fact that retinal ganglion cells should be active only in response to either increases or decreases in light levels at within small regions of visual space — their receptive fields. -Working together with [Greg Field's lab](https://www.neuro.duke.edu/research/faculty-labs/field-lab), we've shown that patterns of alignment between different collections of receptive fields can also be explained using efficient coding theory. This was based on findings from Field lab ([paper](https://www.nature.com/articles/s41586-021-03317-5)), which led to surprising further theoretical results ([paper](https://www.nature.com/articles/s41586-021-03317-5)).

In short, the most information-efficient receptive field arrangements are determined both by levels of noise in the system and the statistics of natural images. Most recently, we've looked at what happens to mosaics as the number of neurons available for coding changes. There, [we found](https://www.biorxiv.org/content/10.1101/2022.08.29.505726v2) that greater numbers of available neurons leads to greater diversity in functionally defined cell types, starting with small temporally smoothing receptive fields and progressing toward larger temporally "differentiating" receptive fields. # Autoencoding whole-brain dynamics + Brain functional magnetic imaging data (fMRI) is one of the most popular modalities in human and clinical neuroscience as it allows researchers to investigate relationships between high-level cognitive functions, brain activity patterns and experimental variables of interest. Traditional fMRI analysis methods utilize a mass univariate approach, wherein a General Linear Model (GLM) is fit to each small volume pixel ("voxel") independently and researchers correct for an inflated false positive rate post hoc. This method has been widely adopted due to its simplicity and ability to produce separate spatial brain maps, capturing the inferred effects of experimental variables on brain-wide activity. However, it fails to account for the rich spatial and temporal information inherent to this modality. In recent work, we've explored the idea of using variational autoencoder (VAE) methods nested inside a Generalized Additive Modeling (GAM) framework to model entire brain volumes together ([paper](https://static1.squarespace.com/static/59d5ac1780bd5ef9c396eda6/t/61080b1bcadb042a79974faf)). This approach better accounts for the spatial dependencies of fMRI data and generates separate, interpretable spatial maps capturing the inferred effects of experimental variables on whole-brain dynamics. In collaboration with [Kevin LaBar's lab](http://www.labarlab.com), we're working to expand on this work with the goal of characterizing brain spatio-temporal dynamics underlying transitions between emotional states in health and in disease. @@ -53,7 +55,7 @@ In recent work, we've explored the idea of using variational autoencoder (VAE) m
