training set is to think of ways to get the most out of a set of parameters. It is advisable to take the logarithm of probability to make the equation linearized.OK, so far, the expression of the derivative of each parameter has been calculated, F_j (x, y) is very easy to find, for any training set this is known. And the later E is more troublesome, it needs to bring all the feasible tags into the FJ, and Times p (here p also, given wj,p is known) but this kind of gradient calculation is very l

The smoking room in the capital airport does not put a few fixed lighters like other airports, but cigarette smoke device, and car smoke device is basically the same: first press the heating, after heating, it will automatically bounce, pull out, the inside of the resistance wire is red, you can point to

However, one of the biggest drawbacks of the hidden horse model is that because of its output independence hypothesis, it can not consider the characteristics of the context, which restricts the selection of the feature, and the maximum entropy hidden horse model solves this pr

At on the afternoon of October 30, at the invitation of Guangzhou guanglianda company, the company participated in the cost management software application (GCM) of the "Expansion Project of the fourth Bureau of construction of Baiyun Airport" organized by the company. Many units in Guangzhou participated in the activity, mainly for housing construction systems, road construction units only support us. The project is located on the right side of the

Finally, I can sit and use my own book to access the Internet.This is the fourth time that I have been to Changi Airport. These four times are all for access to Jakarta, so I want to transfer the traffic here. The hardware and software of Changi Airport are good. From the IT aspect, there are both free PC and free laptop acess. The former must stand on the Internet, and there are many restrictions such as t

Topic PortalTest instructions: Find a straight line, so that the rest of the points are in the same side of the line, and so that the average distance to get straight lines shortest.Analysis: The training guide P274, the convex hull first, if each side is counted side, is O (n ^ 2), however, according to the formula known straight line ax + by + C = 0. The distance from the point (x0, y0) to the line is: Fabs (ax0+by0+c)/sqrt (a*a+ B*B).So as long as the x's and and Y's and, can be calculated at

Semantic tagging is still difficult.The general process is:1. Extract the region feature (if it is a pixel-level operation, the feature is extracted for each pixel, and if it is a hyper-pixel, it is processed for each of the mega-pixel blocks)2. Boost feature (the extracted feature is still not directly as input, to boost the feature into a better classifier)3. One-dimensional logistic regression (using logistic regression for feature classification)4. CRF model for partial smoothingWelcome peop

Then there are m economic routes, next, there will be k commercial lines. You can only hold one commercial line at most. Now you need to find the shortest circuit from s to e, it also outputs the nodes it passes through and the station with a commercial line. Train of

Question: There are two runways, W and E. Each runway is numbered from 0 at each time, and each time there are WI and EI planes arriving at these two runways. In addition, only one plane on the runway can take off at each time. Ask how to minimize the maximum number of aircraft. (The number is calculated at each time point before the plane departs) Ideas: It is also the smallest problem of the maximum value. Binary can be used, but I didn't think of binary.

And find the minimum value of the distance between these points and the straight line. Analysis: As long as the straight line does not pass through the convex hull, the first condition is met. To minimize the distance and distance, the straight line must be on the side of the convex hull. After finding the convex hull, enumerat

The shortest path. Run Dijkstra once from the start point and the end point to get the distance from the start point to any point. Enumerate the commercial lines used to find the optimal solution. When the problem-breaking card is output, it seems that it is more difficult to record the predecessor and output than the algorithm itself. /*by SilverN*/#include Uva11374 Airport Express
