kandi X-RAY | NNetwork Summary
NNetwork is a Custom graph/network/multi-weighted network class optimized for scalable sampling and searching algorithms. NNetwork stores a dictionary that maps each node to a list of its neighbors to allow for O(1) access for finding neighbors. The efficiency of neighbor access is import for sampling algorithm such as random walks and glauber chain walks on graphs. Many packages rely on calculations involving powers of adjacency matrices to calculate random walks of length k, but Monte Carlo sampling algorithms rely on measurements made at every iteration of sampling.

QUESTION
I am seeking to extract timestamps and ip addresses out of log entries containing a varying amount of information. The basic structure of a log entry is:
...ANSWER
Answered 2021-May-19 at 15:40If you are looking for lines that contain both patterns, it may be easiest to do it two separate searches.
If you're searching your log file for lines that contain both "dog" and "cat", it's usually easiest to do this:

I've been playing around with Tkinter recently trying to execute a python script which works on its own. I have looked through a few other posts on the forum, and I can't seem to find a solution to what I'm playing with.
The following script, I do not have an issue with, this works perfectly.
...ANSWER
Answered 2020-Apr-22 at 17:50The problem is when you try to change the value of the label, you are simply changing what the variable icon actually is, you don't pack it into your window.
A simple work around you can do for this is instead of redefining your icon, you could use the .config()
method, which changes the details of a tkinter widget.
For example

ANSWER
Answered 2020-Feb-09 at 13:06Solr now uses the BM25 scorer and not TF/IDF directly. The tf
value used in BM25 is not the exact count of the times the term occur, but uses sqrt(TF)
.

QUESTION
I am currently trying to write a c++ wrapper for PSPNet's prediction (originally in Matlab). PSPNet runs on Caffe.
Situation: I have a trained caffe model, and would like to implement this wrapper to run the segmentation result when given an input. In this case, my crop_size is smaller than it's original size. Thus, it is being cropped manually to multiple 425x425 "frames" and fed forward into caffe net after the pre-processes in a for-loop.
Problem: However, net seems to only be running forward once despite being in a for loop. Supported by its processing time and output, refer below.
This is the incomplete code I am currently trying to work on:
...ANSWER
Answered 2018-Sep-27 at 08:41This issue is solved by wrapping the input channel each time it is changed so that the input will be fed forward correctly.
Thus the function:
QUESTION
I am having a hard time understanding a previous assignment. I was to use functions given in the Addison-Wesley Advanced Programming in the UNIX Environment Third edition text (chapter 16.3.3) to print the host, network, protocol, and services database to the standard output. The feedback my professor gave is below.
Needs serious work (-40); each section of the output needs to contain (possibly) many entries, and must be read in a loop Service port numbers incorrect (-5); the port is a short (NOT an int and in network byte order!); it must be converted using ntohs(3).
My issue is in looping the program to get multiple entries, as I'm not sure how this can be done, especially with the addresses in h_addr_list, since I get Segfaults trying to access anything past [0]. Does the loop have anything to do with the value of h_length?
Here is the code as submitted for the feedback above:
...ANSWER
Answered 2018-Mar-27 at 19:02Each time you call those four get*ent()
functions, they will return one entry of their database, until they return NULL
. Read their manpage to know more, e.g. getservent(3)
. You may also want to close the database connection with their end*net()
counterparts.

QUESTION
I'm experiencing a very strange behaviour in Matlab using the NN toolbox.
I'm building a NN based RL simulation, so I have to train my network repeatedly/calling the train function multiple times (think of a game: after each "move" I observe a reward, so I have a new input->output pair on which I want to train my network).
Every single time I train my network with a single input-output couple, my network will not train anymore, meaning that when I call net=train(net,newinput,newtarget)
its weights don't change at all.
I had a look into it and I discovered that after the first training my network CUTS the connection between input layer and hidden ones, as well as others. see picture below.
here is a simple code able to reproduce this behaviour.
...ANSWER
Answered 2018-Feb-02 at 18:24I believe your problem with the training dataset since when I change the dataset to Matlab default dataset building_dataset
the NN node connection return again without any problem.
