题面在这里! 可以看成点集{a[i]-i}和b之间距离的和,于是找到中位数就可以直接算了2333. #include<bits/stdc++.h> #define ll long long using namespace std; const int N=200005; int a[N],n,num; ll ans=0; int main(){ scanf("%d",&n); for(int i=1;i<=n;i++) scanf("%d"…
机器人运动学逆解的问题经常出现在动画仿真和工业机器人的轨迹规划中:We want to know how the upper joints of the hierarchy would rotate if we want the end effector to reach some goal. IK Solutions: Analytical solutions are desirable because of their speed and exactness of solution. For…

一.LM最优化算法 最优化是寻找使得目标函数有最大或最小值的的参数向量.根据求导数的方法,可分为2大类.(1)若f具有解析函数形式,知道x后求导数速度快.(2)使用数值差分来求导数.根据使用模型不同,分为非约束最优化.约束最优化.最小二乘最优化.Levenberg-Marquardt算法是最优化算法中的一种. Levenberg-Marquardt算法是使用最广泛的非线性最小二乘算法(用模型函数 f 对待估参数向量p在其领域内做线性近似,利用泰勒展开,忽略掉二阶以上的导数项,优化目…

1. Main Point 0x1:行文框架 第二章:我们会分别介绍NNs神经网络和PR多项式回归各自的定义和应用场景. 第三章:讨论NNs和PR在数学公式上的等价性,NNs和PR是两个等价的理论方法,只是用了不同的方法解决了同一个问题,这样我们就形成了一个统一的观察视角,不再将深度神经网络看成是一个独立的算法. 第四章:讨论通用逼近理论,这是为了将视角提高到一个更高的框架体系,通用逼近理论证明了所有的目标函数都可以拟合,换句话说就是,所有的问题都可以通过深度学习解决.但是通用逼近理论并没有告诉…
传送门 C - Linear Approximation 题意: 求 \[ \sum_{i=1}^nabs(A_i-(b+i)) \] \(A_i,b\)给出. 思路: 将括号拆开,变为\(A_i-i-b\),所以将所有的\(A_i\)减去\(i\),然后就是一个经典问题了. Code #include <bits/stdc++.h> #define MP make_pair #define fi first #define se second #define sz(x) (int)(x).s…
