kandi X-RAY | DGI Summary
Here we provide an implementation of Deep Graph Infomax (DGI) in PyTorch, along with a minimal execution example (on the Cora dataset). The repository is organised as follows:. Finally, execute.py puts all of the above together and may be used to execute a full training run on Cora.

QUESTION
I need to find a regex that is able to sanitize the input by removing city codes and keeping the name of the cities.
...ANSWER
Answered 2020-Sep-03 at 06:22The difficulty here is that you want to match a sequence of upper case letters, digits or spaces, but you don't want to match only a space, and probably you don't want to match anything that does not contain any digits.
Although there may be a simpler form, one thing that would work would be to insist on there being a digit, with any number of the other characters both before and after it.
The pattern should also start and finish on a word boundary, so that e.g. it does not strip off the capital letter at the start of the following word.

I want to be able to copy an excel file from one folder to another one. But, everytime it copies it, I want to change the name to TABLEAUPCQ1, TABLEAUPCQ2, TABLEAUPCQ3, and so on..
the reason is, I cant overwrite the excel file if someone is already using it in that other path..

Answered 2019-Nov-06 at 18:07Increase the counter by 1 after each sub execution within a cell value. That way you have the current count stored outside your function.
Grab it, use it, increase it.
QUESTION
I have read several Algorithm books where it is been told brute force approach of Longest Common Subsequence takes 2^n which is exponential in time complexity. Whereas, I've noticed that while I am applying my brute force technique it's taking O(mn) (from my personal observation). I would like to request you please read my approach clearly and visualize in mind and ask question for further clarification if needed. My Approach is following:- Say we have two strings s1 = "ECDGI" , s2 = "ABCDEFGHIJ". Now what I am doing is I chose either one of the given strings. For say, s1. for i = 1 to n (n is the last index of s1), I am taking each value and comparing with the s2 in such a way that for a single character of s1 I am checking with all the characters of s2. Mathematically, ith value is checking through all jth value up to m (m is the last index of s2). Here, if I find any common character I just move to next character from both strings. Then just compute subsequence. I compute all the possible subsequence for each characters from s1 by running n loops. Finally, I compute the largest value. From my understanding it's taking O(mn) time complexity overall. So My Question is, " Is my Time Complexity Calculation right ? "
Trace :
i = 1, value = E, lcs = 3 [EGI]
i = 2, value = C, lcs = 4 [CDGI]
i = 3, value = D, lcs = 3 [DGI]
i = 4, value = G, lcs = 2 [GI]
i = 5, value = I, lcs = 1 [I]
Answer is = 4 (maximum lcs)
My code is given below !
...ANSWER
Answered 2019-Mar-17 at 14:08Your algorithm is wrong. Consider the case when s1 = "AABAA" and s2 = "AAAAB", your code gives 3, but LCS is 4.
Time complexity is O(n * m * (n+m))
Why?
Well let`s consider worst case where we have s1 is n/2 'A' characters and n/2 'B' characters, and s2 is m/2 'A' characters and m/2 'C' characters
- Now if we ignore doIt() function loops themselves give O(n * m)
- So how many times doIt() is called? well for all pairs of n/2 first characters of s1 and m/2 of s2 so n/2 * m/2 times, or if we drop constants O(n * m ) times
- Now lets analyze complexity of doIt()
- It Uses something like 2 pointers to pass both strings so its complexity is O(n+m)
- So total complexity is O(n * m * (n+m)) or O(n^2 * m + m^2 * n)

I have a simple shiny app in which I subset a dataframe by row selection and by column names selection. After subseting by rows I tried 3 different methods to subset it by columns as well but the dataframe remains the same. More specifically I have used :
...ANSWER
Answered 2018-Nov-27 at 21:56You were quite close. The first problem is that in your definition of df_subset, you use a which is not defined anywhere else in the script. I guess you meant to use db there instead of a. The second problem is that when you subset a, you do not assign it again to a, and so when you return a it will not be the subsetted version. Below is the fixed version of df_subset.
QUESTION
I have a shiny app in which I want to subset the datatable displayed based on the user Input in the sidebar. The issue is that as you will see the 3 last rows of my dataframe are not displayed at all while all rows are selected. I suspect that this happens because the "DCH" exists 3 times instead of one but I do not know what happens with "LDP".

Answered 2018-Oct-29 at 18:00I don't know what plotly looks for exactly, but it looks like it doesn't care what your scale_fill_manual labels are and just pulls your fill factor groups as names. So one way would be to just create a label group in your data.
A hacky way is to manually edit the plotly_build() of the plot.

Install DGI
You can use DGI like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
