At the launch of Houdini 17.5 / PilotPDG we showcased PDG's application in Machine Learning in the form of data synthesis, data augmentation, and hyper-parameter space search.  This lesson showcases the data synthesis and augmentation aspects of PDG to further knowledge in this area.


The topic of hyper-parameter space search in Machine Learning covers concepts and ideas that lie outside the scope of this lesson. 


EROSION

Open erosion_synthesis.hip and make sure the provided assets are correctly installed (Assets -> Install Asset Library).  Navigate to obj/topnet1 and cook the imagemagick node.


TERRAIN GEN

Open PDG-ML-TrainingData-DL.hip and make sure the provided assets are correctly installed (Assets -> Install Asset Library).  Navigate to obj/TOP_PDG_ML_TrainingData and cook the imagemagick node.

    Been waiting for this one, thanks for releasing!

    Thank you for these!
    Would be great to share some links/pointers in regards to:
    "The topic of hyper-parameter space search in Machine Learning covers concepts and ideas that lie outside the scope of this lesson. "

    For now I'm going to start learning more about pytorch. and machine learning.
    https://pytorch.org/tutorials/

    Would be great to share the second part specific to the machine learning portion too. Or put a masterclass together on that - I would think a lot of houdini power users would want to extend Houdini/PDG with machine learning knowledge.

    I can not read flt file

    @pclaes: I can recommend the 5 course intro to machine learning by Andrew Ng. He goes into the barebone maths. Course one is mostly about backpropagation and fundamentals, at the end of course 1, but specifically during course 2, it is all about hyper parm optimization and tuning. Very nice one: https://www.coursera.org/specializations/deep-learning

    Thanks for the recommendation Patrick, I will check out the coursera lectures.

    On another note: I seem to be having the same problems as zhaoxinchen007 , unable to read USGS *.flt files. Is this something that Houdini should be able to do? Tried to convert the flts to dxf files but couldn't find a suitable converter right away...

    Houdini supports .flt file after 17.5.174. You should upgrade to the latest daily build.

    Thanks for making them available!

    Where can we find more about developing a ML Tool like the one shown in the second tutorial? Is the source code available somewhere?
    I would love to find more about its development and learn to do something similar with ML

    Just a quick note for those of you looking to use the Terrain_Gen sample with H18:
    - you will actually need to replace the "decompress_downloaded_files" with a new one, as the file_decompress node has changed between H17.5 and H18.0.
    Just create a new decompress TOP, and copy the value of the "Output Folder" param 1from the old file decompress node.

    You should be able to cook the graph without any issue after that.

    The example files only contain the preprocessing steps, none of the ML implementation shown in the video.

  • pixelpicnic 2 years, 4 months ago  | 

    The example urls of the USGS data appear to no longer work.
    What format does this topographical data come in?
    Are there updated links, or something similar I can try with this example?
    Thanks!

    Machine learning models are based on high-quality and relevant data. It guarantee with effectiveness and accuracy. Data preparation is about transforming, cleaning, and organizing, isn't it? I am truly trying to learn it as hard as I can, but sometimes I need https://edubirdie.com/write-my-paper , the service which can help me to write my paper on machine learning. Prepare data is a step that requires hight technical expertise and domain knowledge to ensure accurate and useful machine learning models.
