Looking at Attention’s Scale operation from gradient maximization
?PaperWeekly original · Author | Su Jianlin Units | Dark Side of the Moon Research Directions | NLP, Neural Network We know that the Scale factor of Scaled-Dot Product Attention is, where is the dimension of . The general explanation of this Scale factor is: if it is not divided by , then the initial […]
Bipartite graph determination and maximum matching of bipartite graphs
1. Definition of bipartite graph A bipartite graph is a special undirected graph whose nodes can be divided into two disjoint sets, so that there are no edges connecting any two nodes in the same set, but there are no edges between nodes in different sets. Connected by edges. In other words, if an undirected […]

[AGC034D] Manhattan Max Matching
Problem Statement Snuke is playing with red and blue balls, placing them on a two-dimensional plane. First, he performed $N$ operations to place red balls. In the $i$-th of these operations, he placed $RC_i$ red balls at coordinates $(RX_i,RY_i)$. Then, he performed another $N$ operations to place blue balls. In the $i$-th of these operations, […]
Android 13 – Media Framework (13) – OpenMax (1)
In this section we will learn about the Android OpenMax framework. After understanding the framework, we will go back to understand ACodec, connect MediaCodec – ACodec – OpenMax, and understand the creation control of components and the flow of buffers. This article is a personal study note. If there are any errors, please point them […]
