A former MIT student reflects on a hardware security research paper he co-authored, "There’s Always a Bigger Fish: A Clarifying Analysis of a Machine-Learning-Assisted Side-Channel Attack." The paper, which demonstrated a machine-learning-assisted side-channel attack executable in web browsers and highlighted how system interrupts can leak user information, has received significant awards. The author discusses the challenges of writing about the research, particularly the dual narrative of ML's potential for attacks and its frequent misapplication, and how the project profoundly influenced his academic and personal path.

Researchers are developing AI models to predict and control the behavior of fusion plasma in real-time. These models aim to optimize the process of achieving stable fusion reactions, which is crucial for developing clean energy sources. The project utilizes machine learning techniques to analyze complex plasma dynamics and enable precise manipulation. AI

The Free Software Foundation (FSF) is developing criteria to define what constitutes a "free" machine learning application. Their working group has concluded its efforts and is drafting a formal definition. This definition will require that all software components, training data, and associated scripts respect the four freedoms of free software. Furthermore, the FSF believes that model parameters must be included in the release and be redistributable by users for an ML application to be considered free. AI

A U.S. Geological Survey study has estimated that between 5 and 19 million tons of lithium reserves are located beneath southwestern Arkansas, utilizing machine learning and water testing. This potential reserve could meet projected global demand for lithium in car batteries nine times over by 2030 if commercially recoverable. The research focused on brines within the Smackover Formation, offering a way to extract valuable commodities from waste streams associated with oil and gas operations. AI

A developer has created a "Deal With It" emoji generator that is described as "over-engineered." The tool allows users to upload an image and apply the iconic "Deal With It" sunglasses animation, with the project being shared on Hacker News. AI

This paper explores the gap between current AI's language capabilities and its mathematical reasoning abilities. It proposes an information-theoretical approach to developing an AI mathematician, focusing on discovering new conjectures rather than proving existing theorems. The core idea is that a valuable set of theorems should efficiently summarize provable statements and be closely related to many of them. AI

A new AI coding editor startup, PearAI, has faced significant backlash for initially releasing its product under a proprietary license despite being based on an open-source project. PearAI founder Duke Pan admitted the tool was a clone of another AI editor, Continue, and that the initial closed license was generated by ChatGPT. Following criticism and community notes on X, PearAI reverted to the original Apache open-source license, with the founder apologizing for the lack of clarity. AI

The Federal Trade Commission (FTC) has reached a settlement with AI startup DoNotPay, requiring the company to pay $193,000 for making deceptive claims about its AI lawyer service. The FTC found that DoNotPay falsely advertised its AI chatbot as a substitute for human lawyers without conducting adequate testing or employing legal professionals to verify its outputs. This action is part of a broader FTC initiative, "Operation AI Comply," aimed at curbing deceptive AI marketing and protecting consumers from fraudulent schemes. AI

Haystack Software has launched Haystack Editor, a new product that combines a traditional code editor with an infinite canvas interface. This visual approach aims to improve code comprehension and navigation, offering features like lightweight debugging and extensibility. The editor is available for Windows, macOS, and Linux, with weekly updates and an open contribution model for community involvement. AI

The concept of model homotopy, applying topological ideas to machine learning, suggests that a single model may not fully capture a modeling situation. Instead, a trajectory of fits, parameterized continuously by weights, can offer a richer understanding. This approach can reveal counter-intuitive behaviors, such as linear regression coefficients changing signs multiple times as variables are added, challenging the intuition that coefficients would smoothly interpolate. AI

A new command-line interface tool called Sisi has been released, enabling semantic image search directly on a user's local machine without relying on third-party APIs. Developed using node-mlx, a machine learning framework for Node.js, Sisi supports GPU acceleration on Macs with Apple Silicon and CPU support on x64 Macs and Linux systems. The tool indexes images by computing embeddings with a CLIP model and stores them locally, allowing for fast cosine similarity searches against tens of thousands of images. AI

Relari has launched an auto prompt optimizer designed to improve LLM performance without the need for fine-tuning. This tool uses a dataset of inputs and expected outputs to iteratively refine prompts, aiming for better alignment with domain-specific tasks. The company positions it as a more accessible and transparent alternative to existing prompt engineering frameworks, capable of delivering high-quality results with relatively small datasets. AI

The Open Neural Network Exchange (ONNX) is an open-source format designed to facilitate interoperability between different machine learning frameworks. It defines a computation graph model and standard operators, primarily focusing on inferencing capabilities. ONNX aims to accelerate innovation by enabling developers to choose the best tools for their projects and streamline the path from research to production, with a community-driven governance model for its evolution. AI

Researchers Bartłomiej Cupiał and Maciej Wołczyk observed a significant performance drop in their neural network trained to play NetHack. The model, which had been consistently scoring around 5,000 points, suddenly began scoring only 3,000 points, a 40% decrease. Despite extensive troubleshooting, including code reversion, software stack restoration, and rebuilding the entire system from scratch, the performance issue persisted. AI

Shadowmap.app is a new web-based tool that allows users to visualize and simulate shadows cast by various objects on any date and time. The application provides features such as sun path calculation, sun exposure analysis, and the generation of shadow accumulation maps. It aims to offer a user-friendly alternative to desktop software like Google Earth Pro for shadow studies. AI

Stein's paradox, a counterintuitive statistical concept, demonstrates that in dimensions three and higher, a better estimate of a Gaussian distribution's mean can be achieved than simply using the drawn sample. The James-Stein estimator, which uses a specific formula involving the sample's magnitude and dimensionality, outperforms the naive approach in terms of mean squared error. This paradox challenges conventional statistical intuition, particularly regarding parameter estimation in higher-dimensional spaces. AI

This research paper explores the applicability of Noether's principle, a fundamental concept in physics linking symmetries to conservation laws, within the domain of machine learning. The authors investigate whether similar principles of invariance and conserved quantities can be identified in discrete machine learning processes, such as the training of neural networks. While acknowledging the potential for such connections, the paper suggests that directly applying Noether's theorem to machine learning is complex and not yet fully understood. AI
