Topological spaces satisfying a closed graph theorem
We discuss topological versions of the closed graph theorem, where continuity is inferred from near continuity in tandem with suitable conditions on source or target spaces. We seek internal characterizations of spaces satisfying a closed graph theorem, and we compare closed graph and open mapping spaces.

ChainForge: A Visual Toolkit for Prompt Engineering and LLM Hypothesis Testing
Evaluating outputs of large language models (LLMs) is challenging, requiring making -- and making sense of -- many responses. Yet tools that go beyond basic prompting tend to require knowledge of programming APIs, focus on narrow domains, or are closed-source. We present ChainForge, an open-source visual toolkit for prompt engineering and on-demand hypothesis testing of text generation LLMs. ChainForge provides a graphical interface for comparison of responses across models and prompt variation…

Deep Joint Source-Channel Coding for Adaptive Image Transmission over MIMO Channels
This paper introduces a vision transformer (ViT)-based deep joint source and channel coding (DeepJSCC) scheme for wireless image transmission over multiple-input multiple-output (MIMO) channels, denoted as DeepJSCC-MIMO. We consider DeepJSCC-MIMO for adaptive image transmission in both open-loop and closed-loop MIMO systems. The novel DeepJSCC-MIMO architecture surpasses the classical separation-based benchmarks with robustness to channel estimation errors and showcases remarkable flexibility i…

Cloud cos should create a joint open source maintainers group, well funded, experienced developers etc. ready to hire long term maintainers
Their remit should be to fork every project who goes source available or closed source at the last FOSS commit and maintain it properly as a going concern.
This will either stop this shit or ensure ongoing stewardship.
Should be trivial budget wise given what they make from these code bases.

Context-Aware Clustering using Large Language Models
Despite the remarkable success of Large Language Models (LLMs) in text understanding and generation, their potential for text clustering tasks remains underexplored. We observed that powerful closed-source LLMs provide good quality clusterings of entity sets but are not scalable due to the massive compute power required and the associated costs. Thus, we propose CACTUS (Context-Aware ClusTering with aUgmented triplet losS), a systematic approach that leverages open-source LLMs for efficient and…

Studying LLM Performance on Closed- and Open-source Data
Large Language models (LLMs) are finding wide use in software engineering practice. These models are extremely data-hungry, and are largely trained on open-source (OSS) code distributed with permissive licenses. In terms of actual use however, a great deal of software development still occurs in the for-profit/proprietary sphere, where the code under development is not, and never has been, in the public domain; thus, many developers, do their work, and use LLMs, in settings where the models may…

Soft Prompt Threats: Attacking Safety Alignment and Unlearning in Open-Source LLMs through the Embedding Space
Current research in adversarial robustness of LLMs focuses on discrete input manipulations in the natural language space, which can be directly transferred to closed-source models. However, this approach neglects the steady progression of open-source models. As open-source models advance in capability, ensuring their safety also becomes increasingly imperative. Yet, attacks tailored to open-source LLMs that exploit full model access remain largely unexplored. We address this research gap and pr…

I remember that back in the day, I've hit a #Python package that would attempt to be closed-source by shipping only a .pyc file… for Python 2.5. As you can imagine, this didn't work out — though it was a bit of a hassle to get a working decompiler back then (we didn't have a Python version older than 2.7.x in #Gentoo at the time). However, I don't really remember what it was and how it worked out in the end.

Online Foundation Model Selection in Robotics
Foundation models have recently expanded into robotics after excelling in computer vision and natural language processing. The models are accessible in two ways: open-source or paid, closed-source options. Users with access to both face a problem when deciding between effective yet costly closed-source models and free but less powerful open-source alternatives. We call it the model selection problem. Existing supervised-learning methods are impractical due to the high cost of collecting extensi…

This spacetime has a directional singularity at the origin of the coordinates (related to the diverging vorticity field of the fluid there), which is surrounded by a toroidal region where closed timelike curves (CTCs) are allowed, leadin…

We obtain the closed form expression for the metric perturbation around de Sitter spacetime generated by a matter source below Hubble scale both in generalized harmonic gauge and in Bondi gauge up to quadrupolar order in the multipolar expansion, including both parities (i.e. both mass and current quadrupoles). We demonstrate that such a source causes a displacement memory effect close to future infinity that originates, in the even-parity sector, from a $Λ$-BMS transition between the two non-…

Enhancing Fault Detection for Large Language Models via Mutation-Based Confidence Smoothing
Large language models (LLMs) achieved great success in multiple application domains and attracted huge attention from different research communities recently. Unfortunately, even for the best LLM, there still exist many faults that LLM cannot correctly predict. Such faults will harm the usability of LLMs. How to quickly reveal them in LLMs is important, but challenging. The reasons are twofold, 1) the heavy labeling effort for preparing the test data, and 2) accessing closed-source LLMs such as…

I suppose everyone and their grandmother is now using the xz/sshd exploit to further their own agenda, so I am going to take this opportunity to further mine as well.
1. #Autotools are a bad build system. If configure scripts are completely unreadable, there should be no surprise that people won't notice obfuscated malicious code in there, provided that everything else is obfuscated by design.
2. Static linking and vendoring is bad. Do you know why the prompt #security response was possible? Because we just had to revert to older liblzma. We didn't have to check, patch and re-release hundreds of projects. It wouldn't be this easy with #RustLang and cargo.
3. You can blame #OpenSource for being underfunded and open to abuse in core system packages. However, no IT project can be resilient to a sufficiently powerful bad actor, and that it happened to xz is just an incident. Corporate projects aren't resilient to it, neither is proprietary, closed-source software.
So, embrace #Meson, embrace dynamic linking, embrace distribution packaging and donate to open source developers.
