在完成SVM作业的基础上,Softmax的作业相对比较轻松. 完成本作业需要熟悉与掌握的知识: cell 1 设置绘图默认参数 mport random import numpy as np from cs231n.data_utils import load_CIFAR10 import matplotlib.pyplot as plt %matplotlib inline plt.rcParams['figure.figsize'] = (10.0, 8.0) # set default s
作业内容,完成作业便可熟悉如下内容: cell 1 设置绘图默认参数 # Run some setup code for this notebook. import random import numpy as np from cs231n.data_utils import load_CIFAR10 import matplotlib.pyplot as plt # This is a bit of magic to make matplotlib figures appear inline
3.58 long decode2(long x, long y, long z) { int result = x * (y - z); if((y - z) & 1) result = ~result; return result; } 3.59 这个题考察的是2.3.4和2.3.5节的一个定理:w比特长度的两个数相乘,会产生一个2w长度的数,不管这两个数是无符号数还是补码表示的有符号数,把结果截取的低w比特都是相同的. 所以我们可以用无符号数乘法指令mulq实现有符号数乘法:先把数有符号扩
#include<iostream> using namespace std; int main() { ; int shen_gao; cout <<"Please enter your leight in inches:____\b\b\b"; cin >> shen_gao; cout << "It is contains: " << shen_gao / unit << " f
1.java字段初始化的规律 public class gouzao { public static void main(String[] args) { test te=new test(); System.out.println(te.field); te=new test(300); System.out.println(te.field); } } package text9; public class test { { field=100; } public int field=100
练习3.1 #include <iostream> using namespace std; int main() { int sum = 0, val = 50; while (val <= 100) { sum += val; ++val; } cout << "Sum of 50 to 100 inclusive is " << sum << std::endl; return 0; } #include <iostre
一.编写一个方法,使用以上算法生成指定数目(比如1000个)的随机整数. public class suiji { private static final int N = 200; private static final int LEFT = 40; private static final int RIGHT = 10000; private static long x0 = 1L; private long a = 1103515245L; private long c = 12345L
