Magni 1.6.0 released

Our newest version of the Magni software package was just released on the 2nd of November. This particular release has some interesting features we (the team behind the Magni package) hope some of you find particularly interesting.

The major new features in this release are approximate message passing (AMP) and generalised approximate message passing (GAMP) estimation algorithms for signal reconstruction. These new algorithms can be found in the magni.cs.reconstruction.amp and magni.cs.reconstruction.gamp modules, respectively. Note that the magni.cs sub-package contains algorithms applicable to compressed sensing (CS) and CS-like reconstruction problems in general – and not just atomic force microscopy (AFM).

If you are not familiar with the Magni package and are interested in compressed sensing and/or atomic force microscopy, we invite you to explore the functionality the package offers. It also contains various iterative thresholding reconstruction algorithms, dictionary and measurement matrices for 1D and 2D compressed sensing, various features for combining this with AFM imaging, and mechanisms for validating function input and storing meta-data to aid reproducibility.

The Magni package was designed and developed with a strong focus on well-tested, -validated and -documented code.

The Magni package is a product of the FastAFM research project.

Download

  • The package can be found on GitHub where we continually release new versions: GitHub – release 1.6.0 here.
  • The package documentation can be read here: Magni documentation
  • The package can be installed from PyPI or from Anaconda.

iTWIST’16 is taking shape

This year’s international Traveling Workshop on Interactions Between Sparse Models and Technology is starting to take shape now. The workshop will take place on the 24th-26th of August 2016 in Aalborg. See also this recent post about the workshop.

Aalborg is a beautiful city in the northern part of Denmark and what many of you probably do not know is that Aalborg actually scored “Europe’s happiest city” in a recent survey by the European Commission.

It is now possible to register for the workshop and if you are quick and register before July, you get it all for only 200€. That is, three days of workshop, including lunches and a social event with dinner on Thursday evening.

There are plenty of good reasons to attend the workshop. In addition to the many exciting contributed talks and posters that we are now reviewing, we have an impressive line-up of 9 invited keynote speakers! I will be presenting what the speakers have in store for you here on this blog in the coming days.

PEER REVIEW WATCH

Peer-review is the gold standard of science. But an increasing number of retractions has made academics and journalists alike start questioning the peer-review process. This blog gets underneath the skin of peer-review and takes a look at the issues the process is facing today.
