NodePiece is a "tokenizer" for reducing entity vocabulary size in knowledge graphs. Instead of shallow embedding every node to a vector, we first "tokenize" each node by K anchor nodes and M relation ...

Abstract: Shortest path algorithms such as shortest path first (SPF) and constrained shortest path first (CSPF) are widely used in online traffic engineering where connections need to be set up one at ...

So, you’re looking to get better at coding with Python, and maybe you’ve heard about LeetCode. It’s a pretty popular place to practice coding problems, especially if you’re aiming for tech jobs.

Are you aiming for a FAANG company or want to crack your first tech interview? Data structures are the backbone of coding interviews. This subject shows your problem-solving, logic, and optimization ...

If you are just joining or still wrapping your head around time complexity, start with my first post on Big-O Notation. It explains how we think about performance and why it matters when writing ...

Getting started with LeetCode can feel like a lot, especially if you’re just beginning your coding journey. So many problems, so many concepts – it’s easy to get lost. But don’t sweat it. This guide ...

Adopting a path-planning technique requires a thorough assessment, understanding, mapping, and tracking of the robot’s position in its configuration area, as shown in Fig. 2. The significant ...

Knowledge graphs have been a useful tool for many biomedical applications because of their effective representation of biological concepts. Plentiful evidence exists linking the gut microbiome to ...
