Learning Bits

Our interactive application to georeference outdoor web camera views has been published on GitHub.

I gave a presentation at the E-AI Summer Workshop on Products and Services on how we use machine learning to develop our QC system for surface data and to communicate its results.

The first two papers of the GCOS SwissPhenocam project are now available online.

Nicola will be presenting our recent progress on using deep learning models for camera-based visibility estimation at this year's CIMO TECO conference.

Our work on photographic visualization of weather forecasts has made it to TV, as part of a segment on AI applications for meteorology :-) Thank you to Daniele Nerini for the presentation.

Our paper on photographic visualization of weather forecasts has been published in Volume 2, Issue 1 of Artificial Intelligence for the Earth Systems (AIES), which is a recently established journal of the American Meteorological Society.

I was invited by Céline Portenier and Stefan Wunderle to present our work on photographic visualizations of weather forecasts in the Colloquium in Climatology, Climate Impact and Remote Sensing at the University of Berne.

The 2022 ECMWF Machine Learning Workshop provided a virtual forum for the discussion of machine learning applications for NWP and climate services.

I am a member of the Digital Society working group on automated decision making systems (ADMS).

KNMI held a one day symposium on various aspects of data science for meteorology and climatology.

The MET Alliance is a group of "national aeronautical meteorological service providers from eight European States that cooperate on further improvement and rationalisation of the meteorological services for aviation".

The EUMETNET Workshop on AI for Weather and Climate took place at the Royal Meteorological Institute in Brussels - my last opportunity to travel abroad in 2020.

Our paper on "Detecting temperature induced spurious precipitation in a weighing rain gauge" has been published in Meteorologische Zeitschrift, Vol. 28, No. 3.

I'm a member of the newly founded EUMETNET Scientific and Technical Advisory Committee Working Group on Automated Quality Control.

Having trouble to connect wireless headphones with your MacBook?

After a discussion with Andrew Su, this post has been updated to include information on how to select the temperature sensor that controls the fan speed.

This post has been updated for Yosemite and now mentions bugs in Apple's version of ssh-add.

I recently switched from iOS to Android with the goal of obtaining more control over my smartphone.

My webhost does not support ssh, the only secure transfer method that they provide is FTPES.

"nscancor" is an R package for canonical correlation analysis (CCA) under constraints.

My Retina MacBook Pro (early 2013 model) has been too quiet lately.

A sane backup strategy is guided by the data recovery needs and the appropriate threat model.

Version 0.4 of the nsprcomp package brings several improvements: The various deflation methods have been replaced with generalized deflation (Mackey, 2009), which directly optimizes the additional variance explained by each component.

When we published our 2008 ICML paper on sparse and non-negative PCA, I thought it might be worthwhile to provide a Matlab implementation of our algorithm as well.

I sometimes get funny feelings in my wrists.
