Abstract: Many real-world networks are characterized by directionality; however, the absence of an appropriate Fourier basis hinders the effective implementation of graph signal processing techniques.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Getting a handle on LeetCode can feel like a big task, especially when you’re starting out. But with the right approach and tools, it becomes much more manageable. Python, with its clear syntax and ...

In the signature of Graph.simple_cycles, the default argument for output is stated as 'epath', when the default is actually 'vpath'. import igraph as ig G = ig.Graph.Full(4) print(G.simple_cycles()) ...

A fast method is presented for finding a fundamental set of cycles for an undirected finite graph. A spanning tree is grown and the vertices examined in turn, unexamined vertices being stored in a ...

Gartner has released its 2025 Hype Cycle report. AI agents and data are at their most inflated and need precise application to yield results. The report also emphasized trust and safety efforts as ...

LangGraph Multi-Agent Swarm is a Python library designed to orchestrate multiple AI agents as a cohesive “swarm.” It builds on LangGraph, a framework for constructing robust, stateful agent workflows, ...

Making sense of the economy requires more than just tracking the latest data—it demands a framework for connecting the dots. The good news is that the economy doesn’t move in random spurts—it follows ...

We know that the sun has entered its peak phase of activity, called solar maximum. But are we still in it, or is solar maximum already behind us? Let's see what the data has to say. However, the ...
