Data Fusion Tutorial at the [BC]^2

We are excited to host a three-hour tutorial on data fusion at the Basel Computational Biology Conference. To this end we have prepared a series of short lectures notes that accompany the recently developed Data Fusion Add-on for Orange.

We design the tutorial for data mining researchers and molecular biologists with interest in large-scale data integration. In the tutorial we focus on collective latent factor models, a popular class of approaches for data fusion. We demonstrate the effectiveness of these approaches on several hands-on case studies from recommendation systems and molecular biology.

This is a high-risk event. I mean, for us, lecturers. Ok, no bricks will probably fall down. But, in the part of the tutorial, this is the first time we are showing Orange’s data fusion add-on. And not just showing: part of the tutorial is a hands-on session.

We would like to acknowledge Biolab members for pushing the widgets through the development pipeline under extreme time constraints. Special thanks to Anze, Ales, Jernej, Andrej, Marko, Aleksandar and all other members of the lab.

    Great tool. But how to get the missing entries like in movie rating by data fusion?

    …gettong my feet wet with Orange. Great program!
    However, any FUSION workflow fail:

    Could not create ‘Fusion Graph’

    Traceback (most recent call last):
    File “C:\Python34\lib\site-packages\Orange\canvas\scheme\widgetsscheme.py”, line 341, in create_widget_instance
    widget.__init__()
    File “C:\Python34\lib\site-packages\orangecontrib\datafusion\widgets\owfusiongraph.py”, line 92, in __init__
    self._create_layout()
    File “C:\Python34\lib\site-packages\orangecontrib\datafusion\widgets\owfusiongraph.py”, line 128, in _create_layout
    self.table = gui.TableWidget(info, select_rows=True)
    AttributeError: ‘module’ object has no attribute ‘TableWidget’

    I have reinstalled the Fusion add-on, same problem. Can anyone help? Thanks.

      Dear Stefan,
      This has been an issue since we’ve refactored a part of the code. We’re fixing it as we speak. You can expect the fixes in the new release.
