registration-closed
The seats are filled in the registration order. If a cancellation is received five (5) business days prior to the course, the course fee will be refunded with the exception of a handling fee of 10 €. For no-shows and cancellations after the cut of date no refunds will be made. Registration can be transferred to someone else from the same organization without additional charge.

Payment can be made with electronic invoicing, credit card, or direct bank transfer. Note that for electronic invoicing you need the operator and e-invoicing address (OVT code) of your organization. Please also note that invoice reference is needed for electronic invoicing in your organization, so please have this available when registering.

Practicalities: event-support@csc.fi

This course gives a practical introduction to machine learning for spatial data, both to shallow learning and deep learning models, especially convolutional neural networks (CNN).

The course consists of lectures and hands-on exercises. OrfeoToolBox and scikit-learn will be used for the shallow learning exercises on local PCs. keras, (pytorch) and solaris will be used for deep learning exercises on Puhti-AI.

If you have not worked with Puhti or Taito before, please attend the optional Puhti intro at the end of second day.


Learning outcome
After the course the participants should have the skills and knowledge needed to begin applying machine learning and deep learning for different tasks and utilizing the GPU resources available at CSC for training and deploying their own neural networks.

Prerequisities

  • Basics of geoinformatics
  • Basics of Python. The course will include a fair amount of reading and writing Python code, so you should be able to follow Python syntax. If you need to refresh your Python skills you can go through the materials of Helsinki University GeoPython course.
  • very basic Linux commands: cd, ls, mv, cp, rm, chmod, less, tail, echo, mkdir, pwd. If unfamiliar take a look for example at LinuxSurvival first two modules.

The course is similart the Practical machine learning for spatial data course kept in autumn 2019.
