kandi X-RAY | cpd Summary
Coherent Point Drift (CPD) is a point-set registration algorithm, originally developed by Andriy Myronenko et al. This is a C++ library that runs CPD. CPD can be compared to Iterative Closest Point, another point-set registration algorithm that is widely used. While ICP minimizes point-to-point distances, CPD uses a Gaussian Mixture Model to minimize the error between a point and all other points. If you're thinking that this is very computationally intensive, you're right — both the CPD algorithm and the underlying error calculations take a lot of time, which is why we've created fgt to speed up those Gauss transforms. We hope this library provides a freer and more performant alternative to the original reference Matlab implementation.

QUESTION
I wonder whether this plugin could fit our purpose : we would like to make sure that our participants spend at least 3 hours on their course otherwise their CPD fees might not be paid for by their sponsors. The idea would be to have a visual indication of the time one has spent on their course, while giving these people the opportunity to spend more time on the course if they wish to do so.
Thanks for helping, Best,

Answered 2022-Apr-01 at 08:18Have you considered how you would define "time spent on course"?
Is it the total of the time between the user's first opening of one of the pages of the course and them logging out? (or timing out, assuming they just close their browser window and don't hit "log out")
That doesn't work very well, as the user can easily open their browser, log into the course, then, 30 seconds later, close their browser and walk away - so does that count as 2 hours usage (until their session times out)?
Or you could try tracking each page load and counting up the time between the first page load of a session and the last page load of the session? But a user could still be watching Netflix in another browser window and every hour or so, just click on a link in the training window.
Do you put some sort of artificial limit in there - e.g "each click must be within 5 minutes of each other to count as the same session" - that won't work if one of the pages is a 15 minute video, or a document that takes 10 minutes to read.
Could you measure the time the server spent generating the pages for the user to view? (Not really a serious suggestion, as the server would only take a fraction of a second to generate each page viewed - but, realistically, that's the amount of time that the LMS is actually being accessed directly by the user)
If you really want to track the user's time spent on the course, you'd have to resort to extremely invasive measures - locking down the browser so that the user cannot switch away from the training tab, using a webcam to track their movements, to make sure they're actually there looking at the screen and interacting with the site.
The end result of this - a user has "clocked-in" and, for whatever definition you want to use, added up the required amount of time on the course.
Ultimately - time spent is a fairly meaningless measure and almost impossible to measure accurately anyway. A much more useful metric is to use assessment to determine if the user has actually learnt what you want them to learn - it doesn't really matter if a user has spent 5 minutes on a course or 3 hours - if they can demonstrate that they understand the topic, then the training has been successful.

I have a table in BigQuery that I want to update on a daily basis whenever new data come in to another table. Now, I also need to do some casting of variable that exist in a nested column in the original dataframe. Hence, I do the following thing:
...ANSWER
Answered 2021-Oct-22 at 21:55Some operations must be performed on a single machine[1]. When your data overflows the slot's memory, you experience the error that appears. My approach on what you need is to change the slot type to a higher memory machine[2], or switch to flat-rate pricing to have reservation resources[3].
Otherwise, you will have to follow the query best practices to avoid single slot operations on too much data. One thing that usually helps is to move to STANDARD SQL if you haven't done that yet. Additionally, I’m attaching some information on how the memory in BigQuery works during an execution[4].

QUESTION
Im having trouble getting sonarQube to output the coverage report of my java Spring project. Because of this it always displays 0.0% coverage in the interface. I followed this and it still will not generate the file. The following is the relevant part of the pom.xml and at the bottom is the log. By default the coverage report is supposed to be in target/site/jacoco/jacoco.xml; however even when I comment out it still does not output anything.
ANSWER
Answered 2021-Oct-13 at 21:42The property is called "sonar.coverage.jacoco.xmlReportPaths" (note the "s"). Your text and your code sample specify different property names and values for this. Figure out where it is and use that. Different build configurations might put it in a different place. Look in the workspace of your build to see where the file was created.

QUESTION
I am using the MetaModelStructuredComp Component to perform an interpolation in a 2D grid.
When checking the option to compute it with the 'slinear' method, the interpolation appears to work correctly, but when checking partial derivatives with a complex step, it returns a large error (order of 10^-1) for the derivatives with respect to the second dimension and second node (they belong to a grid point, but also the first node).
This does not happen when checking with all the other methods (cubic returning order of 10-15, and scipy_slinear with a finite difference check in the order of 10-10). The scipy_slinear check returns an analytical and numerical finite difference of that component which is almost identical to the one returned by the numerical finite difference of the slinear method (around -0.03338752, but note that the analytical returns -0.05107948)
I am not sure if its something I am missing, or if there is an error in the analytical partials for the slinear.
In my code, the first dimension is alpha with trained data of shape (12,), and second dimension mach (5,). I am checking with two outputs (C_D (12, 5) and C_L (12, 5), both having the same large error)

...ANSWER
Answered 2021-Jul-23 at 13:13So, what I think is happening here (and what I stumbled upon with my random table) is that 7.0 is one of the points on which your Mach data is defined. When you use the 'slinear' method, the derivatives are discontinuous at that point. It's just one of the disadvantages of the method.
The discrepancy in the check happens because the bracketing algorithm, which figures out which bin you are interpolating, chooses the "left" bin when you are on a grid point, but the finite difference or complex step chooses the "right" bin because the default check direction is "forward".
To alleviate future confusion, we're going to set the check direction to "backward" for the structured meta model component whenever the 'slinear' method is chosen. The derivatives "matched" when I made this change. This change should make it into OpenMDAO 3.11.
