OpenSpeedTest is handy to measure the performance of the local (W)LAN: It is like any other speed test service, but it runs locally. Setting it up on a Synology NAS is easy.

I recently welcomed a group of new team members who were not used to the email centric culture. This can be overwhelming: We have dozens of email lists and automated systems sending status updates and alerts that everyone receives email from. Many of us who have lived this way for a long time have coping mechanisms. These are mine.

I am a fan of the Argon One M.2 case raspberry Pi case. I finally got my hands on one for the Raspberry Pi which runs my Home Assistant. The transfer wasn’t entirely straight forward. The notes below might help the next person doing this.

This week, I added a bunch of Aqara Water Leak Sensors to my home assistant setup.

I plugged my TV into a smart plug which conveniently also measures power flow through it. I wanted to use this to detect whether the TV was on.

As mentioned before, I run work on a VM on my personal machine. I use Hyper-V as the hypervisor. For a while, struggled how to get the webcam to be available in the VM. Turns out you can just use the Remote Desktop Protocol (RDP) for this.

Home automation has been an interest of mine for a while. Here, I collect notes on what worked for me. Both as a reminder for myself and in the hopes that it is useful to others dabbling in the space. This is not a tutorial for any of the devices mentioned. There are plenty of those available on the internet.

Yesterday, I introduced The Apache Software Foundation to the large crowd at the TVM conference. You can download my slides as PDF and PPTX.

I am happy to announce that my team has five papers accepted in the workshop section of NeurIPS this year:

Yunseong Lee, Alberto Scolari, Byung-Gon Chun, Marco Domenico Santambrogio, Markus Weimer, Matteo Interlandi

I am honored and humbled to receive the Test of Time Award together with Alex Smola and Alexandros Karatzoglou. It is given to our work on matrix factorization you can find here on my website. Here is the deck Alex used at ECML/PKDD 2018 today in his talk to commemorate the work, give it perspective with the field since and produce some ideas of where the field might go.

Visual Studio now can install Anaconda’s Python distribution. Awesome! What isn’t so awesome: The Anaconda Prompt in the start menu that installs doesn’t work. When I oppened it, I was greeted with:

Are you amazed by the progress machine learning has made over the past few years? Are you at the same time frustrated that so relatively few organizations in the world can benefit from ML? Do you read NIPS, COLT, ICML and KDD papers for pleasure? If you answered yes to these I want to talk to you. Apply within.

The team dedicated to Apache REEF at Microsoft is hiring. Apply within :-)

In this post, I describe to verify .md5 and .SHA512 hashes with PowerShell, without any additional tools.

Today, Twitter announced the open sourcing of Heron, their successor to Apache Storm. Heron’s Apache Hadoop YARN port is built using Apache REEF. I’m excited and looking forward to the interesting edge cases they’ll report over on the dev list :-)

Sergiy Matusevych presented Apache REEF at Apache Big Data 2016 in Vancouver, BC. Find the slides below.

Over in Apache REEF, we needed to make our solution compile in both Visual Studio 2013 and 2015. The main impediment to that was the C++ code in the project, which needs to be compiled with the “right” compiler, depending on the version of Visual Studio used. Below, I describe how we created a project file that can be compiled uniformly across Visual Studio versions.

Using GitHub and Apache’s JIRA for code and issue management can be a bit of a pain. I started a Firefox extension that helps a bit with is. For now, it only adds the JIRA link to the Pull Requests overview page. More to come in the future. Download Version 0.0.1, Source.

Below, you find my slides from my talks in Europe. You can also download them as a PPTX or PDF using the controls at the bottom of the frame.

Raghu Ramakrishnan just posted about what we’ve been up to at Microsoft in the last few years:

During October 2015, I am visiting several European universities and academic institutions.

I’ve decided to move this page to Jekyll and have it hosted on GitHub. For the next couple of weeks, this likely means that the page will be riddled with dead links. Stay tuned…

The proceedings of KDD Cup 2011 are now online at JMLR.

Friday was my last day at Yahoo!

I’ve been invited to talk about our work on ScalOps at Berlin Buzzwords! According to the Schedule, I’ll be speaking June 4th, 17:04 - 17:45 in the room “Kleistsaal”.

So, you read Alex’ post on applying the hashing trick to matrix factorization or our paper on the subject and thought you’d just go ahead and implement it. And instead of computing two hashes, one for the Rademacher function ( [latex]\sigma[/latex] in the paper) and one for the index in the storage array, you compute just one and use the sign of the hash as [latex]\sigma[/latex] and the absolute value for the index. Which looks something like this in Java:

Yahoo! is running a learning to rank challenge. So finally, we can see a fair comparison between all the different approaches to learning to rank.

We are glad to announce that our MLOSS 2010 workshop at this years ICML conference has been accepted!

We are therefore happily accepting software submissions. The deadline for the submissions is April 10th, 2010. If accepted, you can present your software to the workshop audience, which is a great opportunity to make your piece of software more known to the machine learning community.

Like last time, we will use mloss.org for managing the submissions. You basically just have to register your project with mloss.org and add the tag icml2010 to it. For more information, have a look at the workshop page.

I’m a reviewer of the Special Issue of the Journal of Web Semantics on “Bridging the Gap” - Data Mining and Social Network Analysis for Integrating Semantic Web and Web 2.0. Here is the call for papers.

We just released version 0.1 of cofirank, the implementation of our algorithm of the same name.

My grad school is organizing a conference next summer on e-learning – technology enhanced learning for those from across the ocean. You might think “yawn! yet another conference!”, but this one is special:

A few people contacted me with the question how the NDCG optimization in our NIPS07 paper on collaborative ranking is done in detail. Unfortunately, we did not manage to squeeze these details into the paper itself. Luckily, there is the internet and I just uploaded my notes on this to the CofiRank site. Please note that these notes are not peer reviewed. If you find a bug/typo/whatever in the derivations, I would be more than happy to hear from you!
