Xh176233756: xh176233756 The biggest headache of geometric computing is the large amount of code and the high accuracy. The problem of code size is generally not a problem as long as you pay attention to the accumulation of templates at ordinary times. Precision Problems are hard to say. Sometimes a precision problem may become a bottleneck of a question ". Over the years, the questions have basically evolved towards a more and more non-card

50000 pictures of the handwritten data set 0~9 recognition of Arabic numerals, and the accuracy of the analysis of the results,Handwritten digital data set download: http://yann.lecun.com/exdb/mnist/First of all, using the properties of the picture itself, the image of the gray average to identify the classification, I run out of the accuracy rate is about 22%Using the gray average of images to classify and

Previous article, compared three kinds of algorithms to realize the handwritten numeral recognition, in which, SVM and neural network algorithm performance very good accuracy rate is above 90%, this article further discusses to the Neural Network algorithm optimization, further improves the accuracy rate, through the test discovery, the accuracy rate raises a lot

This question is directly simulated. However, I hung the Qaq on the last two points. The only thing you should pay attention to is accuracy... If it is used to convert the value behind double to an integer, we forget to use Longlong... Sad #include 　　 Background Who is the most virtual in the attached IDC? Class 2 and Class 1 ***! It feels good, right? Description Today, the zombie czy drove an excavator to school (......). But he found that hi

I will not talk much about the questions. Here, DP [I] [0] indicates the probability that I will be left in the second box after the first box is obtained. The expected result is DP [I] [0] * I. DP [I] [1] indicates the probability that I will be left in the first box after the second box is obtained. DP [I] [0] = P ^ (n + 1) * (1-p) ^ (n-I) * C (2 * n-I, n-I) = P ^ (n + 1) * (1-p) ^ (n-I) * (2 * n-I )! /(N-I )! /N! DP [I + 1] [0] = P ^ (n + 1) * (1-p) ^ (n-i-1) * C (2 * n-i-1, n-i-1) = P ^ (n

D can also say:D = K1/(1 ^) + K2/(^ 2) + K3/(+ ^3) + ... + kn/(ten ^ n)Extended to binary, the representation of decimal fraction is:D = B1/(2 ^ 1) + b2/(2 ^ 2) + B3/(2 ^ 3) + ... + bn/(2 ^ n)Now the question is how to obtain B1, B2, B3,......,bn. The algorithm is more complex to describe, or to speak with numbers. To declare, 1/(2 ^ n) This number is special, which I call a bit-order value.For example 0.456, 1th bit, 0.456 is less than the bit order value 0.5 is 0, 2nd bit, 0.456 is greater th

Test instructions: For a given 12 numbers, the average is calculated.Analysis: This problem is the precision control problems, if the control accuracy, the best way is to use the integral type.The code is as follows:#include HDU 4493 Tutor (Control accuracy)

Transmission DoorThere are 2 piles of stones. A B Two people take turns, a take first. Each time you can take any or 2 of the same number of stones from a heap, but not to be taken. The man who got the last 1 stones won. Suppose a B is very clever, there is no mistake in the process of taking the stone. Give the number of 2 stones and ask who will win the game at the end.For example, 2 stones were 3 and 5. So no matter a how to take, B has a corresponding method to get the last 1.InputLine 1th:
