I am rather new to ML and started using ML.NET early this year. Perhaps I am not educated enough on it, but I am attempting to find information on implementing GPU-based binary classification using C# and LightGBM. Despite numerous searches I cannot find any documentation or examples. I would very much appreciate any assistance anyone can offer.
B., I am on the ML.NET team at Microsoft. We do not currently support GPU for LightGBM, but this is something we are considering implementing over the next few months. If you would like, please make an issue on our GitHub repository and provide more detail about your use case.

I am almost new in recurrent neural network. Recurrent neural networks like rnn, lstm, bi-lstm etc. are almost all implemented in python. I want a C# tool of recurrent neural network and found RNNSharp. The inputs of this framework are complex. Is it possible to implement a bidirectional lstm with RNNSharp. If possible, then please help me to create the model with minimal Snippet Code or a link. Thank you.
The input of RNNSharp is compatible with CRFSharp, which supports templates. In addition, RNNSharp won't get updated for any new feature, you could try Seq2SeqSharp which supports both bi-LSTM and transformer models. It's tensor based and support CPU and multi-GPUs. Here is the link: https://github.com/zhongkaifu/Seq2SeqSharp
You can get input/config examples on that page.
Here's my question, how does one "hack" the CustomCommand in Enterprise Architect's API to figure out what it's capabilities are? Here's what I'm currently using it for, which seems to be an accepted (by the community) and usable function:
repository.CustomCommand("Repository", "ImportRefData", xml);
I want to see what else I can do with it, namely some exporting of said reference data.
Also, while Sparx cannot officially support this functionality since it's undocumented, what are the odds that this command will stay functional with updated versions of EA, do they have a history of breaking illegal code like this?
Thanks,
Alex
The answer is: you can't. The few commands I documented were from postings on the Sparx forum. Eventually they originated from Sparx support itself. I remember having read from someone who knew about one of the commands asking for more info. But Sparx did not unveil more than was known. I tried to find the strings in the EXE but to no avail.
Since the function is there for quite some years and Sparx is very reluctant to substantial changes in the API it will likely not change. So it's save to use the function in future. IIRC Sparx itself recommended the use in certain cases. But only on the forum...
I've been fussing around with NHibernate tutorials for months (yeah...literaly) with no success. I wanted to just get a basic "hello world" level example down pat so I could work with it and massage it into a proper use case but I can never get past the deprecated code or missing library files.
I can only assume that it is me who is at fault because of NHibernate's popularity. Would someone pleeeeeeasee lead me to a self-contained example that I can just download and run? I would absolutely appreciate it.
Many thanks to everyone (with the exception of Diego) for their help. Special thanks to Michael Buen for his suggestion with using Fluent NHibernate.
There is a great example of NHibernate 3.0 in action here that I got to work: http://www.d80.co.uk/post/2011/02/20/Linq-to-NHibernate-Tutorial.aspx
Now all I need to do is learn exactly what's going on and mold it to my uses.
I tried to google but didn't find a decent tutorial with snippet code.
Does anyone used typed DataSets\DataTable in c# ?
Is it from .net 3.5 and above?
To answer the second parts of the question (not the "how to..." from the title, but the "does anyone..." and "is it...") - the answer would be a yes, but a yes with a pained expression on my face. For new code, I would strongly recommend looking at a class-based model; pick your poison between the many ORMs, micro-ORMs, and raw ADO.NET. DataTable itself does still have a use, in particular for processing and storing unpredictable data (where you have no idea what the schema is in advance). By the time you are talking about typed data-sets, I would suggest you obviously know enough about the type that this no longer applies, and an object-model is a very valid alternative.
It is still a supported part of the framework, and it is still in use as a technology. It has some nice features like the diff-set. However, most (if not all) of that is also available against an object-based design, with classes and properties (without the added overhead of the DataTable abstraction).
MSDN has guidance. It really hasn't changed since typed datasets were first introduced.

There are tons of videos available here: http://www.learnvisualstudio.net/series/aspdotnet_2_0_data_access_and_databinding/
And I found one more tutorial here: http://www.15seconds.com/issue/031223.htm
Sparingly.... Unless you need to know to maintain legacy software, learn an ORM or two, particularly in conjunction with LINQ.
Some of my colleagues have them, the software I work on doesn't use them at all, on account of some big mouth developer getting his way again...
Im trying to implement NLP in my project,
I need to Tag the words as Person,Location ,Organix=sation etc..If any body knows the logic please let me know..

The task you want to perform is known as Named Entity Recognition (NER).
The majority of software for doing NER is in Java. For example, the Stanford NER system and the OpenNLP NER system. There are far fewer similar libraries written in C#, however I found SharpNLP through a Google search. I have not used it personally so I have no idea how well it works.
There is a nice web-service by Reuters: http://www.opencalais.com/.
You can access it via an API.
I thought that the demo was impressive http://viewer.opencalais.com/.
I did not pursue it further, as I want to create a German application. Calais is only supporting English.
