kandi X-RAY | bpr Summary
Bayesian Personalized Ranking is a learning algorithm for collaborative filtering first introduced in: BPR: Bayesian Personalized Ranking from Implicit Feedback. Steffen Rendle, Christoph Freudenthaler, Zeno Gantner and Lars Schmidt-Thieme, Proc. UAI 2009. This is a simple Python implementation of BPR for matrix factorization based on the C# one provided by the original authors in MyMediaLite, see I’ve also implemented a BPR version of SLIM: Sparse Linear Methods for Top-N Recommender Systems. Xia Ning and George Karypis, Proc. ACM RecSys 2012.

I am using Schematron.NET in a C# project to validate the XML (format below):
...ANSWER
Answered 2021-Mar-30 at 17:02I can't speak to the C# code, but here are some things in the Schematron code:
- As mentioned in the comments, the Schematron code should have a single document element. In Schematron, it is the
element. - When you refer to elements in the "
http://etcetc.com" namespace, you need to use the "bpr:" namespace prefix that you declared in the Schematron schema. - The Schematron
element cannot have a@nameattribute. It can have an@idattribute or a</code> child element (both are optional).</li> </ol>Here's a working example of the Schematron code that generates a failed assert on the sample XML document you provided:

Answer: Oracle Java SE Licensing FAQ
In 2019, Oracle changed their licensing structure for Java Standard Edition (SE). Prior to this, Java SE could be used for any purpose without the need to purchase a license from Oracle. Currently, some uses of the product, including deployment into a production environment, require a paid-for license. Refer to the Oracle Java SE Licensing FAQ for details.
The good news is that before making this change, Oracle dedicated itself to better supporting the open source community by promising that their OpenJDK releases would be as similar as possible to the SE counterparts. Since Java 11, Oracle's OpenJDK builds are essentially identical in function to the SE versions. The OpenJDK releases can be used for any purpose, free of charge.
There are a variety of other OpenJDK-based distributions out in the wild besides the one directly provided by Oracle. The one I highly recommend is Amazon's Corretto JDK, available in a number of versions. This build is fully supported by Amazon. It is used by them internally for all of the Java infrastructure that backs their AWS services. Amazon promises regular security updates for any major version for at least 3 years. It is completely free, regardless of if you run it on AWS or elsewhere.
Per @BasilBourque, you might wish to check out Java Is Still Free, which explains the bigger JDK picture both in brief and in gory detail.
UPDATE: Yikes. I think I must be the "random authority on the internet" that the other answer speaks of. I don't think I've implied that I have any particular "authority", and I hope and expect that the information I provide will be taken like any other found on S.O., with an appropriate amount of skepticism per the stakes involved.
By all means, please don't go doing anything that might get you in legal trouble based solely on what I have said above. I provide a pointer above to the Oracle docs, from which I first got the above information a few months back. But even with that in hand, I think it makes good sense for you to run any licensing questions by your lawyer if you happen to have one.

I have intitalized the rate per hr(bpr) as 12.My aim was to find the gross pay,taxes and net pay given the no of hours entered by the user.Also if the hrs are more than 40 the rate increases by 1.5.So the rate for the extra hrs is 18ph instead of 12.Here is my code:
...ANSWER
Answered 2020-Nov-20 at 13:22You are invoking undefined behavior by passing data having wrong type to printf().
%d is for printing int, but you are passing double.
To print double via printf(), you should probably use %f or %g. (There are also some other specifiers to print double in different formats)
QUESTION
I'm using the below code to grab the RGB value of the point tapped inside an imageview (the imageview is a color wheel). Tapping the image works perfectly, and an RGB value is returned - however it's not the correct color. For example I tap the yellow area of the wheel, and a red RGB value is returned. Does anyone know what I'm missing/why this might be happening?

QUESTION
What is the best approach for setting up an RTC connection that will success the first time ?
The following code sometimes works, sometimes doesn't. I think it's a problem with addIceCandidate being called either before or after createAnswer, and I don't know which is preferable, or if that is even the issue (for why its not working all the time, just paste it into a browser, and try it a few times, you should see that at least sometimes the "call" button doesn't work all the time):
ANSWER
Answered 2020-Mar-25 at 09:52Please look again at documentation. At first, you are using async functions, so it could not resolve at the time then you call it (for example user doesn't answer for prompt or browser decline it at all). At second, you're not handling errors, add catch() block to your code and browser will answer to your question itself
QUESTION
I'm trying to create a data visualization that's essentially a time series chart. But I have to use Panda, Python, and Plotly, and I'm stuck on how to actually label the dates. Right now, the x labels are just integers from 1 to 60, and when you hover over the chart, you get that integer instead of the date.
I'm pulling values from a Google spreadsheet, and for now, I'd like to avoid parsing csv things.
I'd really like some help on how to label x as dates! Here's what I have so far:
...ANSWER
Answered 2020-Feb-16 at 08:17Right now, the x labels are just integers from 1 to 60, and when you hover over the chart, you get that integer instead of the date.
This happens because you are setting rand_x as x labels, and rand_x is an array of integer. Setting labels_dict={'X': 'Date', 'Y': 'Rate (%)'} only adding text Date before x value. What you need to do is parsing an array of datetime values into x. For example:

Install bpr
You can use bpr 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.
