Catastrophic forgetting remains a fundamental challenge for neural networks when tasks are trained sequentially. In this work, we reformulate continual learning as a control problem where learning and preservation signals compete within neural activity dynamics. We convert regularization penalties into preservation signals that protect prior-task representations. Learning then proceeds by minimizing the control effort required to integrate new tasks while competing with the preservation of prior tasks. At equilibrium, the neural activities produce weight updates that implicitly encode […]

This paper proposes an axiomatization of the absolute infinite within a non-recursively enumerable class theory, called MKmeta, that maximally extends the formal MK: Morse-Kelley with global choice (GC). Class ordinals and class cardinals avoid the Burali-Forti paradox and GC is assumed to warrant comparability of class cardinals. A Hamkinsian multiverse Mh is defined as the collection of all the models v of any syntactically consistent, formal extension of MK. MKmeta is then rigorously defined by ranging over Mh […]

Professor Naftali Tishby passed away in 2021. Hope the post can introduce his cool idea of information bottleneck to more people. Recently I watched the talk “Information Theory in Deep Learning” by Prof Naftali Tishby and found it very interesting. He presented how to apply the information theory to study the growth and transformation of deep neural networks during training. Using the Information Bottleneck (IB) method, he proposed a new learning bound for deep neural networks (DNN), as […]

Nighttime vehicle detection poses significant challenges due to reduced visibility, uneven illumination, and increased noise in low-light imagery. While deep learning approaches have achieved remarkable success in daytime scenarios, their application to nighttime conditions remains constrained by the scarcity of specialized datasets and the computational demands of existing architectures. This paper presents three primary contributions to address these challenges. First, we introduce the Low-light Vehicle Annotation Dataset (L-VAD), comprising 13,648 annotated frames captured exclusively during nighttime conditions across […]

In this tutorial, we build a cost-aware planning agent that deliberately balances output quality against real-world constraints such as token usage, latency, and tool-call budgets. We design the agent to generate multiple candidate actions, estimate their expected costs and benefits, and then select an execution plan that maximizes value while staying within strict budgets. With this, we demonstrate how agentic systems can move beyond “always use the LLM” behavior and instead reason explicitly about trade-offs, efficiency, and resource […]

arXiv:2601.00088v1 Announce Type: new Abstract: Large Language Models (LLMs) show promise for equation discovery, yet their outputs are highly sensitive to prompt phrasing, a phenomenon we term instruction brittleness. Static prompts cannot adapt to the evolving state of a multi-step generation process, causing models to plateau at suboptimal solutions. To address this, we propose NeuroSymBO, which reframes prompt engineering as a sequential decision problem. Our method maintains a discrete library of reasoning strategies and uses Bayesian Optimization to […]

TL;DR I tested 112 Product Hunt startups with 2,240 queries across ChatGPT and Perplexity. The results challenge conventional wisdom about “Generative Engine Optimization” (GEO): The Discovery Gap: ChatGPT recognizes 99% of products directly but recommends only 3% organically (30:1 ratio) GEO doesn’t work (yet): Zero correlation between GEO optimization and ChatGPT discovery Traditional SEO wins: Backlinks (r=+0.32) and Reddit presence (r=+0.40) are the strongest predictors Full paper: arXiv:2601.00912 n Code & Data:GitHub The Problem: ChatGPT Visibility for Startups […]
