🧠 American math genius checked out the latest OpenAI's language model

Terence Tao is widely regarded as a math genius. He scored a 760 on the SAT math section at age 8, and became the youngest gold medalist in the International Mathematical Olympiad at age 13. Tao earned his PhD from Princeton at just 20.

Recently on Mastodon he shared his experience with OpenAI's GPT-o1 model, noting its advancements in handling mathematical tasks. In his experiments, the model successfully identified and applied Cramer's theorem, showing clear improvement over past versions. However, when tackling more complex problems, it still needed guidance, resembling the work of a capable but inexperienced graduate student.

Tao believes that with further development and integration of tools like computer algebra systems, AI could soon assist in advanced research. While current models require effort to prompt and verify, he sees potential for broader use in mathematics as they continue to improve.

🤦‍♂️ 5 Techniques to Simulate Embedded Software

Hardware often arrives late in product development, but embedded systems engineers can use simulation techniques to test and validate software without physical hardware. These methods accelerate development and improve product reliability.

💻 Virtual Hardware (ISS): Simulates microcontrollers at the instruction level, allowing early software validation. Challenges include limited peripheral support and cost considerations.

💻 Functional Simulation: Focuses on application functionality and business logic without low-level hardware dependencies, enabling early customer feedback and reducing rework costs.

💻 Hardware-in-the-loop (HITL) Simulation: Integrates real hardware interfaces to validate software with virtualized sensors and actuators, ensuring robustness in diverse scenarios.

🔨 System-level Simulation: Simulates entire systems to test interactions comprehensively, suitable for high-reliability applications despite being time-consuming and costly.

📊 Behavioral Simulation: Models high-level system behavior, such as state machines, aiding in system requirement validation and iterative design improvements.

Implementing these techniques enhances development efficiency, accelerates time to market, and reduces costs by identifying and fixing issues early in the development cycle. Start with basic simulations like functional and behavioral approaches to maximize ROI and project success.

🤖 Insecure Deebot robots collect photos and audio to train AI

Ecovacs Deebot vacuums have been caught gathering photos, videos, and voice recordings inside users' homes to train AI models. Despite privacy concerns, the company claims users willingly participate in a data collection program aimed at improving product functionality.

The program involves collecting 2D/3D house maps, microphone recordings, and camera images, some of which may be retained even if deleted. While Ecovacs says the data helps enhance AI capabilities, the company is under scrutiny due to cybersecurity flaws that could expose sensitive user information.

A similar issue arose with iRobot when intimate images taken by its vacuums were leaked online by contractors analyzing the footage, raising broader concerns about how companies handle user data. These incidents highlight the growing need for stronger safeguards to protect consumer privacy in smart home devices.
