Manacher’s Algorithm for Longest Palindromic Substring
Manacher’s Algorithm for Longest Palindromic Substring Longest Palindromic Substring has a straight-forward description [1]: Given a string s, return the longest palindromic substring in s. The goal of this article is to understand how to solve it using the tricky Manacher’s algorithm. A naive method iterates all the element and then expands from the center…

Running EchoMimicV2 on Windows 11
EchoMimicV2 is an opensource framework for audio driven human portrait animation. Compared to many other solutions (talking head) which only focusing on facial animation and head movement, this framework includes upper-body movement. The official repository tested the system on the Linux environment. However, this article records the process of running this framework on Windows 11…

Vision Transformers (ViT) Experiments Using PyTorch and PyTorch Lightning
Also can be seen at: https://medium.com/@heyulong3d/vision-transformers-vit-experiments-using-pytorch-and-pytorch-lightning-61e26738d9dd?sk=8326d1c2706380c7599c67e53d2e2b5c Overview This article will implement Vision Transformer (ViT) from scratch using PyTorch and PyTorch Lightning. It also covers insightful experiments with different patch size, model size, attention heads, and other improvements like overlapping patch embedding on CIFAR-10 dataset. This article will focus more on practice and experiments rather than…

[UE5]Clarification of Different Dependency Lists in a Build.cs File
I have the same question with darkgaze‘s question in the Unreal forums. It is kind of annoying to decide which dependency lists property should I use. PublicIncludePathModuleNames (List<String>) List of modules names (no path needed) with header files that our module’s public headers needs access to, but we don’t need to “import” or link against.…

[LeetCode] Graphs
Types of graphs: Terminologies: 1 Disjoint Set 1.1 Overview of Disjoint Set Q: Given the vertices and edges between them, how could we quickly check whether two vertices are connected? The disjoint set is a data structure(others might refer to it as an algorithm), also known as union-find data structure. The primary use of disjoint…
