To become the king of Codeforces, Kuroni has to solve the following problem. He is given n numbers a1,a2,-,an. Help Kuroni to calculate ∏1≤i<j≤n|ai−aj|. As result can be very big, output it modulo m. If you are not familiar with short notation, ∏1≤i<…
题目链接  Points Inside A Polygon 题意  给定一个$n$个点的凸多边形,求出$[ \frac{n}{10}]\ $个凸多边形内的整点. 把$n$个点分成$4$类: 横坐标奇,纵坐标奇 横坐标奇,纵坐标偶 横坐标偶,纵坐标奇 横坐标偶,纵坐标偶 根据鸽笼原理,这$4$类点中至少有一类点数目不小于$[ \frac{n}{4}]\ $ 每一个类别中,每两个点的中点肯定为整点,并且当这两个点不在凸多边形上相邻的时候, 他们一定在凸多边形内. 那么把这$4$个类别里面的点分别处理…

论文地址:https://arxiv.53yu.com/abs/2106.07577 基于 F-T-LSTM 复杂网络的联合声学回声消除和语音增强 摘要 随着对音频通信和在线会议的需求日益增加,在包括噪声.混响和非线性失真在内的复杂声学场景下,确保声学回声消除(AEC)的鲁棒性已成为首要问题.尽管已经有一些传统的方法考虑了非线性失真,但它们对于回声抑制仍然效率低下,并且在存在噪声时性能会有所衰减.在本文中,我们提出了一种使用复杂神经网络的实时 AEC 方法,以更好地建模重要的相位信息和频率时间…

GeoHash 核心原理解析       引子 一提到索引,大家脑子里马上浮现出B树索引,因为大量的数据库(如MySQL.oracle.PostgreSQL等)都在使用B树.B树索引本质上是对索引字段进行排序,然后通过类似二分查找的方法进行快速查找,即它要求索引的字段是可排序的,一般而言,可排序的是一维字段,比如时间.年龄.薪水等等.但是对于空间上的一个点(二维,包括经度和纬度),如何排序呢?又如何索引呢?解决的方法很多,下文介绍一种方法来解决这一问题.   思想:如果能通过某种方法将二维的点数…
