implementation

问题 I would like to create an LSTM class by myself, however, I don't want to rewrite the classic LSTM functions from scratch again. Digging in the code of PyTorch , I only find a dirty implementation involving at least 3-4 classes with inheritance: https://github.com/pytorch/pytorch/blob/98c24fae6b6400a7d1e13610b20aa05f86f77070/torch/nn/modules/rnn.py#L323 https://github.com/pytorch/pytorch/blob/98c24fae6b6400a7d1e13610b20aa05f86f77070/torch/nn/modules/rnn.py#L12 https://github.com/pytorch

问题 We are given a sorted array. Let the initial value of pass be zero. We can do the following operation any number of times: Select any k numbers at a time. Add them all up. Add this sum to pass If a number, say x , is being selected for the first time from the array, then it is considered as x only. When it is selected for the second time , then it is considered as -x , and for the third time, again as x , and so on... For example, let the array be [-14, 10, 6, -6, -10, -10, -14] and k = 4 ,

问题 The implementing-result-paging-in-hibernate-getting-total-number-of-rows question trigger another question for me, about some implementation concern : Now you know you have to reuse part of the HQL query to do the count, how to reuse efficiently? The differences between the two HQL queries are: the selection is count(?) , instead of the pojo or property (or list of) the fetches should not happen, so some tables should not be joined the order by should disappear Is there other differences? Do

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I want to use the Java Persistence API (JPA) for my web application. There are popular JPA implementations like Hibernate , Toplink and EclipseLink . What implementation is a good choise and why? 回答1: When the Java Persistence API (API) was developed, it became popular very

问题 I'm currently in the middle of writing a small PNG image I/O library myself for learning purposes. My problem is the following: I created a small PNG only 2 by 2 pixels in dimension and opened it in a hex editor to study its contents. This is the image I created using GIMP and stored with a compression of "9". (Please note that this is an enlarged image of the original 2 by 2 pixel image ;) ) So I guess uncompressed, this would look something like this in memory: 00 00 00 FF 00 00 00 00 FF 00

问题 I have an assignment and trying to understand something. I have an instruction to create two interfaces: IComparable and IPrintable . Also, I need to create a template called Interval . I am given the main function and I need to implement these classes accordingly so it will work as intended. This is the function I am currently implementing (the comments displays what the input should look like): void testDate() { Date independence(14, 5, 1948); cout << independence << endl; Date otherDate =

问题 I have a question about efficient implementation. Lets say I have two arrays: One array is all possible items in a house: Table, Chair, TV, Fireplace, Bed The other is an array of items in a particular house: Table, TV, Bed I also have two list boxes: 1. listbox for items in the house - the "HAS" list box 2. listbox items not in the house - the "NEEDS" list box I need to list the items already in the house in the "HAS" list box as well as the items that are NOT in the house in the "NEEDS"

问题 I have my own solution to import monthly sales data in my windows form application. When a user click on import button, the program is actually running but it looks like it's not responding. The process takes a long time about 5 minutes. So, I'd like to implement a progress bar with status strip label to display as an user interface and let the users know how much the task is done. This is also my first time using a progress bar in my program. So, I read through some tutorials which show how

问题 Does anyone have an idea how is the method/function Int() or floor() implemented? What I am looking for a respective implementation as the following is for abs() function. Int Abs (float x){ if x > 0 return x; else return -x } I am struggling to find a solution for it without using the modulus operator. 回答1: Seems to me like floor(n) = n - (n % 1) should do the trick. 回答2: Using the IEEE 754 binary floating point representation one possible solution is: float myFloor(float x) { if (x == 0.0)

问题 I get the concept behind a trie. But I get a little confused when it comes to implementation. The most obvious way I could think to structure a Trie type would be to have a Trie maintain an internal Dictionary<char, Trie> . I have in fact written one this way, and it works , but... this seems like overkill. My impression is that a trie should be lightweight, and having a separate Dictionary<char, Trie> for every node does not seem very lightweight to me. Is there a more appropriate way to
