Hi! I am trying to import data from a csv file by using CsvReader from Accord.IO. I'm using the method CsvReader.FromText(string text, bool hasHeaders); but I get an error saying that my string is not in the correct format. The string is the filepath to my csv file?

Hello!

Does anybody have any experience using this library for optimization?

Hi guys, I was looking for deep learning in .Net. Does Accord Framework provides Deep learning APIs?

AMIDIBOSS

@AMIDIBOSS

No idea

Hi there, not yet. Support for deep learning in Accord.NET will come through Keras-Sharp (https://github.com/cesarsouza/keras-sharp)

@AbhimanyuAryan

Hey I'm new to machine learning. I'm a Game Developer
Any resources(maths/logic) you would suggest me for ML/DL? So, I can pick Accord.net APIs & also know what's happening underneath

Hi everybody, a fundamental question busy my mind for a long time (May I wrong : )
Why Accord.NET, until exist wrappers for powerful OpenCv in .NET and deep learning libraries like TensorFlow, CNTK (support C#)?
I googling about Accord.NET performance comparison (e.g. image processing), key advantages and I've got nothing a satisfy answer :(

César Souza

@cesarsouza

Hi Hashem, I would say the main point is that Accord.NET has a higher level of abstraction than the libraries you mentioned, and unlike them it is a unified framework where you can treat images, text, audio, under similar interfaces. And those interfaces also happen to depend on very fundamental .NET types such as jagged and multidimensional matrices, so even if you need to interop with other libraries such as OpenCV or CNTK you do not have to rewrite your application from scratch to use them. You can select things to use from Accord.NET and from OpenCV for example (that's part of the reason for the "accord" name).

Also, since the main goal is to offer an unified experience, Accord.NET can eventually be extended to use those libraries. For example, the .Neuro project will soon be updated to use TensorFlow/CNTK under the hood, but hopefully with a simpler API.

If I had to pick an example I would say that Accord.NET is like scikit-learn for Python, except that it also includes more fundamental libraries such as for mathematics and image processing if you need.

@hzawary

@cesarsouza Thanks to fast reply and fully explanation. Accord is great, friendly and my favorite and thank u for introducing and spend ur time for it :)
Accord is applicable and very nice, but still slow in speedy applications than OpenCv. (in some cases e.g. acquiring Image Data, image processing like perform filters is very slow :(

Hashem Zavvari

@hzawary

@cesarsouza I also glad to hear good news about improve Accord on deep learning :)

Hello, is there a way to get a weighted average probability from a GaussianMixtureModel?

I would love to contribute to accord-net!

Hey guys, I just submitted pull request #1326. This adds support to Accord.Video.DirectShow.VideoCaptureDevice for programatically getting/setting signal processor properties (i.e. gain, brightness, hue, etc). Can I get this merged?

Christian Kahr

@dotChris90

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)?

Hi all,Accord.Math.Transform does not include "Inverse FFT" or "Inverse DFT",where can I find it？Thanks

Augusto Radtke

@aradtke

Hi team, is there any documentation regarding which methods can throw which exceptions? For example PolynomialLeastSquares can throw a SingularMatrixException on Learn. I couldn't find anything on the website, thanks.

Hi everyone. Does anyone has any news about Dr. Cesar? He have not been active in the last few months. I worry about him.

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 )

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
remote: Permission to accord-net/framework.git denied to marshmit.
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

Marwin Schmitt

@marshmit

So I fork accord on my account, submitted the branch there and then did the pull request ... is that the way it should be done? If so maybe it should be put on the contribution page...

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 ...
