Semantic communication promises task-aligned transmission but must reconcile semantic fidelity with stringent latency guarantees in immersive and safety-critical services. This paper introduces a time-constrained human-in-the-loop reinforcement learning (TC-HITL-RL) framework that embeds human feedback, semantic utility, and latency control within a semantic-aware Open radio access network (RAN) architecture. We formulate semantic adaptation driven by human feedback as a constrained Markov decision process (CMDP) whose state captures semantic quality, human preferences, queue slack, and channel dynamics, and solve it via […]

First kākāpō chick in four years hatches on Valentine’s Day First chick of the 2026 breeding season! Kākāpō Yasmine hatched an egg fostered from kākāpō Tīwhiri on Valentine’s Day, bringing the total number of kākāpō to 237 – though it won’t be officially added to the population until it fledges. Here’s why the egg was fostered: “Kākāpō mums typically have the best outcomes when raising a maximum of two chicks. Biological mum Tīwhiri has four fertile eggs this […]

Recurrent and deep neural networks (RNNs/DNNs) are cornerstone architectures in machine learning. Remarkably, RNNs differ from DNNs only by weight sharing, as can be shown through unrolling in time. How does this structural similarity fit with the distinct functional properties these networks exhibit? To address this question, we here develop a unified mean-field theory for RNNs and DNNs in terms of representational kernels, describing fully trained networks in the feature learning ($μ$P) regime. This theory casts training as […]

But the intellectually interesting part for me is something else. I now have something close to a magic box where I throw in a question and a first answer comes back basically for free, in terms of human effort. Before this, the way I’d explore a new idea is to either clumsily put something together myself or ask a student to run something short for signal, and if it’s there, we’d go deeper. That quick signal step, i.e., […]

Writing clear, consistent docstrings in Python helps others understand your code’s purpose, parameters, and outputs. In this video course, you’ll learn about best practices, standard formats, and common pitfalls to avoid, ensuring your documentation is accessible to users and tools alike. By the end of this video course, you’ll understand that: Docstrings are strings used to document your Python code and can be accessed at runtime. Python comments and docstrings have important differences. One-line and multiline docstrings are […]
