Machine learning, computer vision, statistics and general scientific computing for .NET
I am new here
I would love to contribute to accord-net!
hello accord guys - does ACCORD give user the possibility to use "http://accord-framework.net/docs/html/T_Accord_Statistics_Models_Regression_NonlinearRegression.htm" (this example) but without! computing the Gradient? And do Accord has some classes for finding the global Minimum of the corresponding Regression error function (not just local)?

Anybody knows how to fit data with a 4PL model (or even better with 5PL)? I tried using LevenbergMarquardt but the results are poor. You can check my code on StackOverflow ( https://stackoverflow.com/questions/52535521/fitting-4pl-with-levenbergmarquardt )
Can anyone help me for my comment on #1131, I am stuck trying all the solution already provided there!
Is there an example implemented on WPF?
Hi! I've made a small fix for issue #1659 (that I also created ;) )... but I'm new to github and can't push my branch ... I get
git push --set-upstream origin C45_invalid_leafs_fix

fatal: unable to access 'https://github.com/accord-net/framework.git/': The requested URL returned error: 403

... probably I'm not doing it the wrong way ... but the pull request help just says ... push your branch & create pull request ... I'm not understanding what I'm doing wrong
also I get a message that two checks failed. "AppVeyor build failed" and "The Travis CI build failed" - from what I can see in the messages things that have really nothing to do with my code ...
accord-net/framework#1268
is there any way someone could take a look at this

If not, is that a feature that would be appropriate to add to Accord.Audio?
I'm investigating an alternative library for my use case (https://github.com/ar1st0crat/NWaves) but am open to trying my hand at adding resampling to Accord.Audio
win 7 Use recorded video normally win10 cannot
I am new in camera programming. For learning purpose I have download Accord-Framework C# source code.
Thus if we have JPG or MPEG Stream then we can easily display in Accord.Controls.VideoSourcePlayer.
But if we have FFMPEG Stream then how can we display in Accord.Controls.VideoSourcePlayer.
Please anyone can guide me?
Thanks in advance
I might be at the wrong forum - just let me know and I will be on my way. I am using Accord.Video.FFMPEG to create videos in a C# project using Bitmaps as sources. After a few videos has been created (each 5-15 minutes long, 30 fps, FHD, compressed using x264) I get an error: Out of memory. External component has thrown an exception. [libx264 @ 0767eb40] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 AVX2 LZCNT BMI2 x264 [error]: malloc of size 10891456 failed System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.' - To me it seems that when a videofilewriter is flushed, closed and disposed, something remains and after about 5-20 of these has been created (one at a time, disposed before next is created) memory slowly gets exhausted. Is there a known memory leak? Is there a method to reinitialize ffmpeg libraries or do I have to restart the application every time this happens?
Versions used: .NET Framework 4.7.2, Accord.Video.FFMPEG from Nuget Runtime version: v4.0.30319, Version: 3.8.0.0
I also had problems using this nuget package in a .NET Core solution, but got it working in .NET Framework 4.7.2... which is why I use .NET Framework for this solution right now.
