Path Signatures for Feature Extraction. An Introduction to the Mathematics Underpinning an Efficient Machine Learning Technique
We provide an introduction to the topic of path signatures as means of feature extraction for machine learning from data streams. The article stresses the mathematical theory underlying the signature methodology, highlighting the conceptual character without plunging into the technical details of rigorous proofs. These notes are based on an introductory presentation given to students of the Research Experience for Undergraduates in Industrial Mathematics and Statistics at Worcester Polytechnic …

"The Tax Foundation is a veteran anti-tax campaign organization from the United States. It has been around since 1937 when it was founded by top brass from companies such as Standard Oil and General Motors. Close links to some of the biggest corporations in the US has been a constant feature of the organization, as has its political aim of bringing down taxes"

Modelling bulk mechanical effects in a planar cellular monolayer
We use a three-dimensional formulation of the cell vertex model to describe the mechanical properties of a confluent planar monolayer of prismatic cells. Treating cell height as a degree of freedom, we reduce the model to a two-dimensional form. We show how bulk effects, associated with cell volume and total surface area, lead to coupling between energy variations arising from changes in cell apical area and apical perimeter, a feature missing from standard implementations of the two-dimensiona…

Designing the Future of Entrepreneurship Education: Exploring an AI-Empowered Scaffold System for Business Plan Development
Entrepreneurship education equips students to transform innovative ideas into actionable entrepreneurship plans, yet traditional approaches often struggle to provide the personalized guidance and practical alignment needed for success. Focusing on the business plan as a key learning tool and evaluation method, this study investigates the design needs for an AI-empowered scaffold system to address these challenges. Based on qualitative insights from educators and students, the findings highlight…

So, all decks red alert. It seems for my future job I can't use but need to use either Mac or Windows.
I can't be assed to use that go back to that pile of sh*t that windows it nowadays and I have no experience with Mac and honestly don't want any.
So I guess Mac would be the choice, right? At least its said to be stable and most stuff can be done with the same shell.
I'm just a bit horrified by the outlook and would appreciate any tips on how to approach …

Supervised Link Prediction in Co-Authorship Networks Based on Author Node-Based Features
Predicting the emergence of future research collaborations between authors in academic social networks (SNs) is a very effective example that demonstrates the link prediction problem. This problem refers to predicting the potential existence or absence of a link between a pair of nodes (authors) on the co-authorship network. Various similarity and aggregation metrics were proposed in the literature for predicting the potential link between two authors on such networks. However, the relevant res…

Now Pocket is going away. Mozilla really loves alienating its userbase these days, huh? Not that all of them used Pocket, but Mozilla pushed it hard and integrated it into the browser - only to kill it with pretty short notice. https://support.mozilla.org/en-US/kb/future-of-pocket…

"Maybe one day, after we have conquered code, we will apply what we have learned by giving away our free labor towards the creation of other common goods. Think about it; spending 3 hours a day, but instead of coding, feeding homeless people, planting trees, or helping the elders.
