Increase citations, ease review & collaboration – Making machine learning in research reproducible
Jesper Dramsch

Every scientific conference has seen a massive uptick in applications that use some type of machine learning. Whether it’s a linear regression using scikit-learn, a transformer from Hugging Face, or a custom convolutional neural network in Jax, the breadth of applications is as vast as the quality of contributions.

This tutorial aims to provide easy ways to increase the quality of scientific contributions that use machine learning methods. The reproducible aspect will make it easy for fellow researchers to use and iterate on a publication, increasing citations of published work. The use of appropriate validation techniques and increase in code quality accelerates the review process during publication and avoids possible rejection due to deficiencies in the methodology. Making models, code and possibly data available increases the visibility of work and enables easier collaboration on future work.

This work to make machine learning applications reproducible has an outsized impact compared to the limited additional work that is required using existing Python libraries.

Evaluating your machine learning models: beyond the basics
Gaël Varoquaux, Arturo Amor

This tutorial will guide towards good evaluation of machine-learning models, choosing metrics and procedures that match the intended usage, with code examples using the latest scikit-learn's features. We will discuss how good metrics should characterize all aspects of error, e.g. on the positive and negative class; the probability of a detection, or the probability of a true event given a detection; as they may need to catter for class imbalance. Metrics may also evaluate confidence scores, e.g. calibration. Model-evaluation procedures should gauge not only the expected generalization performance, but also its variations.

JAX and Flax: Function Transformations and Neural Networks
Andreas Steiner

Modern accelerators (graphics processing units and tensor processing units) allow for high performance computing at massive scale. JAX traces computation in Python programs through the familiar numpy API, and uses XLA to compile programs that run efficiently on these accelerators. A set of composable function transformations allows for expressing versatile scientific computing with an elegant syntax.

Flax provides abstractions on top of JAX that make it easy to handle weights and other states that is required for solving problems using neural networks.

This talk first presents the basic JAX API that allows for computing gradients, compiling functions, or vectorizing computation. It then proceeds to cover other parts of the JAX ecosystem commonly used for neural network programming, such as basic building blocks and optimizers.

How to increase diversity in open source communities
Maren Westermann

Today state of the art scientific research strongly depends on open source libraries. The demographic of the contributors to these libraries is predominantly white and male [1][2][3][4]. In recent years there have been a number of various recommendations and initiatives to increase the participation in open source projects of groups who are underrepresented in this domain [1][3][5][6]. While these efforts are valuable and much needed, contributor diversity remains a challenge in open source communities [2][3][7]. This talk highlights the underlying problems and explores how we can overcome them.

Array expressions and symbolic gradients in SymPy
Francesco Bonazzi

SymPy is an open source computer algebra system (CAS) written in Python.

The recent addition of the array expression module provides an alternative to the matrix expression module, with generalized support to higher dimensions (matrices are constrained to 2 dimensions).

Given the importance of multidimensional arrays in machine learning and mathematical optimization problems, this talk will illustrate examples of tensorial expressions in mathematics and how they can be manipulated using either module or in the index-explicit way.

Conversion tools have been provided to SymPy to allow users to switch an expression between the array form and either the matrix or index-explicit form. In particular, the conversion from array to matrix form attempts to represent contractions, diagonalizations and axis-permutations with operations commonly used in matrix algebra, such as matrix multiplication, transposition, trace, Hadamard and Kronecker products.

A gradient algorithm for array expressions has been implemented, returning a closed-form array expression equivalent to the derivative of arrays by arrays. The derivative algorithm for matrix expressions now uses this algorithm, attempting to convert the array back to matrix form if trivial dimensions can be dropped.

[Maintainer Track] Scientific Python / SPECs
Jarrod Millman

The Scientific Python project aims to better coordinate the ecosystem and grow the community. This session focuses on our efforts to better coordinate project development, and to improve shared infrastructure. In this session together we will discuss project goals and recent technical work.

The Scientific Python project’s vision is to help pave the way towards a unified, expanded scientific Python community. It focuses its efforts along two primary axes: (i) to create a joint community around all scientific projects and (ii) to support maintainers by building cross-cutting technical infrastructure and tools. In this session we mostly focus on the second aspect.

The project has already launched a process whereby projects can, voluntarily, adopt reference guidelines; these are known as SPECs or Scientific Python Ecosystem Coordination documents. SPECs are similar to projects specific guidelines like PEPs, NEPs, SLEPs, and SKIPs, to name a few. The distinction being that SPECs have a broader scope, targeted at all (or most) projects from the scientific Python ecosystem.

The project also provides and maintains tools to help maintainers. This includes a theme for the project websites (used on, e.g., numpy.org and scipy.org), a self-hosted privacy-friendly web analytics platform, a community discussions forum, a technical blog, and project development statistics.

We present these tools, discuss various upcoming SPECs, and highlight the project’s future potential.

Data-Driven Thresholding for Extreme Event Detection in Geosciences
Milton Gomez

Extreme weather events are a well known source of human suffering, loss of life, and financial hardship. Amongst these, tropical cyclones are notoriously impactful, leading to significant interest in predicting the genesis, tracks, and intensity of these storms - a task which continues to present significant challenges. In particular, tropical cyclogenesis (TCG) can be described as “a needle in a haystack” problem, and steps must be taken to make predictions tractable. Previously, the filtering of non-genesis points by thresholding predictive variables has been described, with thresholds being selected to reduce the number of discarded TCG cases. In the art, this thresholding has often been carried out empirically, that while effective relies on domain knowledge. This talk instead proposes the development of a systematic, machine-learning-based approach implemented in Python. The method is designed to be interpretable to the point of becoming transparent machine learning. Threshold values that minimize the false-alarm rate and maintain a high recall are found, and then combined in a forward selection algorithm. As other extreme events in the geosciences are considered needle in the haystack problems, the described approach can be of use in reducing the variable space in which to study and predict the events. Finally, the transparent nature of the proposed approach can provide simple insight into the conditions in which these events occur.

Discovering Mathematical Optimization with Python
Pamela Alejandra Bustamante Faúndez

Mathematical optimization is the selection of the best alternative with respect to some criterion, among a set of candidate options.

There are multiple applications of mathematical optimization. For example, in investment portfolio optimization, we search for the best way to invest capital given different alternatives. In this case, an optimization problem will allow us to choose a portfolio that minimizes risk (or maximizes profit), among all possible allocations that meet the defined requirements.

In most cases, mathematical optimization is used as a tool to facilitate decision-making. Sometimes these decisions can be made automatically in real-time.

This talk will explore how to formulate and solve mathematical optimization problems with Python, using different optimization libraries.

[Maintainers Track] Contributor Experience & Diversity
Noa Tamir

This is part of the maintainers track.

Most of us have been hearing about Diversity Equity and Inclusion (DEI) for some years now, and even had access to many resources by now. Our projects have codes of conduct, and some have been doing sprints and mentorships. But how much has fundamentally changed?

Let’s meet for an honest conversation about the challenges of DEI actions, and culture change. How do we achieve long-term impact? What are low-hanging fruit? We can share hard-to-ask questions, effective tools, experiences that shaped our approach, and see if we can all nudge each other forward a little.

Inclusion happens at the community level, also when we want to address DEI itself. So, we will need to create a safe space for hard questions and leave judgment at the door.

Thanks to our grant to advance an inclusive culture in the scientific Python ecosystem, we have created the contributor experience lead role. We have been working with NumPy, SciPy, Matplotlib, and pandas to learn how to integrate this new role to a project, and how to introduce contributor hospitality techniques. We are working on creating widely available resources, and we would benefit from hearing from maintainers from the wider community.

The reproducible aspect will make it easy for fellow researchers to use and iterate on a publication, increasing citations of published work. The use of appropriate validation techniques and increase in code quality accelerates the review process during publication and avoids possible rejection due to deficiencies in the methodology. Making models, code and possibly data available increases the visibility of work and enables easier collaboration on future work.

This work to make machine learning applications reproducible has an outsized impact compared to the limited additional work that is required using existing Python libraries.

Real-time estimation of an heat pump I/O state with IoT data.
Davide Poggiali

In the present time, we are facing a continuous growing of the energy price. It is then important to optimize the use of heat pumps, both in domestic and industrial environments. Using an opportunely labeled dataset of accelerometer, speed or relative position over time coming from a cheap sensor it is possible to estimate the I/O state of any heating or cooling engine. This new real-time measure allows then to compute the energy consumption and to study the most cheap usage scheme.
In this presentation we will show a real-case implementation of some fast binary classifiers, from basic statistics to machine learning, assessing the performance of each method in terms of computational time, precision and accuracy levels.

Interactive Data Science in the browser with JupyterLite and Emscripten Forge
Jeremy Tuloup, Thorsten Beier, Martin Renou

JupyterLite is a Jupyter distribution that runs entirely in the web browser, backed by in-browser language kernels including WebAssembly powered Jupyter Xeus kernels and Pyodide.

JupyterLite enables data science and interactive computing with the PyData scientific stack, directly in the browser, without installing anything or running a server.

JupyterLite leverages the Emscripten and Conda Forge infrastructure, making it possible to easily install custom packages with binary extensions in the browser, such as numpy, scipy and scikit-learn.

scikit-learn and fairness, tools and challenges
Adrin Jalali

Fairness, accountability, and transparency in machine learning have become a major part of the ML discourse. Since these issues have attracted attention from the public, and certain legislation are being put in place regulating the usage of machine learning in certain domains, the industry has been catching up with the topic and a few groups have been developing toolboxes to allow practitioners incorporate fairness constraints into their pipelines and make their models more transparent and accountable. Some examples are fairlearn, AIF360, LiFT, fairness-indicators (TF), ...

This talk explores some of the tools existing in this domain and discusses work being done in scikit-learn to make it easier for practitioners to adopt these tools.

Continuous and on demand benchmarking
Mridul Seth

We all know and love our carefully designed CI pipelines, which tests our code and makes sure by adding some code or fixing a bug we aren’t introducing a regression in the codebase. But we often don’t give the same treatment to benchmarking as we give to correctness. The benchmarking tests are usually one off scripts written to test a specific change. In this talk, we will discuss various strategies to test our code for performance regressions using ASV (airspeed velocity) for python projects.

Pragmatic Panel: Build and Deploy Complex Data-Driven WebApps
Pierre-Olivier Simonard

Panel is one of the leading choices for building dashboards in Python. In this talk, we discuss the practical aspects of complex data-driven dashboards. There are tutorials and guides available which help teach new users the basics, but this talk focuses on the challenges of building more complex, industry-ready, deployed dashboards. There are a variety of niche issues which arise when you push the limits of complexity, and we will share the solutions we have developed. We will demonstrate these solutions as we walk through the entire lifecycle from data ingestion, though exploratory analysis to deployment as a finished website.
