Rough path theory is a branch of mathematics arising out of stochastic analysis. One of the main tools of rough path analysis is the signature, which captures the evolution of an unparametrised path including the order in which events occur. RoughPy is our new Python package that aims change the way we think about sequential streamed data.

While Python excels at prototyping and iterating quickly, it’s not always performant enough for whole-genome scale data processing. Flyte, an open-source Python-based workflow orchestrator, presents an excellent way to tie together the myriad tools required to run bioinformatics workflows.

Interactive visualizations are invaluable tools for building intuition and supporting rapid exploration of datasets and models. This paper explains the benefits of IPyVuetify with the ability to arbitrarily overlay widgets and plots on top of others to support more flexible details-on-demand techniques.

The ATLAS experiment at CERN explores vast amounts of physics data to answer the most fundamental questions of the Universe. This paper will describe to a broad audience how a large scientific collaboration leverages the power of the Scientific Python ecosystem to tackle domain-specific challenges and advance our understanding of the Cosmos.

In recent years, WebAssembly has emerged as a widely-supported technology that offers high performance, compact binary size, support for multiple languages, hardware independence, security, and universal platform support. ITK-Wasm brings WebAssembly’s capabilities to scientific computing by combining the Insight Toolkit (ITK) and WebAssembly to enable high-performance spatial analysis across programming languages and hardware architectures.

Jupyter Widgets enable interactive code and data visualization in notebooks, but creating and distributing widgets across the Jupyter ecosystem is challenging. The anywidget project introduces a standard and toolset for portable, web-based widgets in various computing environments, simplifying development and extending compatibility beyond Jupyter. Its approach has fostered a rich widget ecosystem, driving the creation of new widgets and adoption of the standard by multiple platforms.

Learn about its enhanced features for cross-compilation, multi-platform support, and simplified configuration, which enable writing binary extensions with pybind11, Nanobind, Fortran, Cython, C++, and more.

Machine learning is revolutionizing a wide range of research areas and industries, but many ML projects never progress past the proof-of-concept stage. To address this problem, we introduce Model Share AI, a platform designed to streamline collaborative model development, model provenance tracking, and model deployment.

The peracarid taxon Cumacea is an essential indicator of benthic quality in marine ecosystems. This study investigated the influence of environmental (i.e., biological or ecosystemic), climatic (i.e., meteorological or atmospheric), and spatial (i.e., geographic or regional) variables on their genetic variability and adaptability in the Northern North Atlantic, focusing on Icelandic waters.

Presenting a model or algorithm as a GUI application is a common need in the scientific and engineering community. Funix was created to automatically launch apps from existing Python functions, automatically selecting widgets based on the types of the arguments and returning functions according to the type-to-widget mapping defined in a theme.

Understanding neighborhood context is critical for social science research, public policy analysis, and urban planning. We introduce geosnap, the Geospatial Neighborhood Analysis Package, a suite of tools for exploring, modeling, and visualizing the social context and spatial extent of neighborhoods and regions over time.

Science requires new mediums to compose ideas and ways to share research findings iteratively, as early as possible and connected directly to software and data. In this paper we discuss two tools for scientific authoring and publishing, MyST Markdown and Curvenote, and illustrate examples of improving metadata, reimagining the reading experience, including computational content, and transforming publishing practices for individuals and societies through automation and continuous practices.

This article demonstrates practical approaches to fully type-hinting generic NumPy arrays and StaticFrame DataFrames, and shows how the same annotations can improve code quality with both static analysis and runtime validation.

Histopathological images, which are digitized images of human or animal tissue, contain insights into disease state. We present PredX-Tools, a suite of simple and easy to use python GUI applications which facilitate analysis of histopathological images and provide a no-code platform for data scientists and researchers to perform analysis on raw and transformed data.

Jupyter is a popular platform for writing interactive computational narratives that contain computer code and its output interleaved with prose that describes the code and the output. It is possible to use one’s voice to interact with Jupyter notebooks.

Evaluating probabilistic forecasts is complex and essential across various domains, yet no comprehensive software framework exists to simplify this task. Despite extensive literature on evaluation methodologies, current practices are fragmented and often lack reproducibility. To address this gap, we introduce a reproducible experimental workflow for evaluating probabilistic forecasting algorithms using the sktime package.
