2016/09/16, Ubicomp/ISWC206 at Heidelberg

Heidelberg is an excellent choice for the location of a Ubicomp conference as the town is so small. Walking around the streets in the evening, and in any corner you might pump into a friendly nerd! Today, Rosalind Pickard gave the keynote speech and I have to say it was very touching and interesting. Did you know that from the skin response, you can see signals that originate deep in the brain? This cannot be detected even from the traditional EEG! It seems that the connections between the skin, heart, veins etc. from our embyo development period never disappear but are activated in certain situations. Picard also mentioned that you can detect certain seizure by electrodermal activity measurements from one arm, when there is no sign of seizure in the other.

Our workshop HASCA 2016 (4th time this year!) was again a success. We had so many people listening and giving excellent presentations. But something very funny happened during the beginning... I was deep in my thoughts sending email and working on the front row and I noticed two students to appear sitting on my side. I thought, nice that they are so active and would sit in the first row! Then, the other student came to me and said "Hello, you are Susanna?" I am like yeah and looking at him for his name. He said 'I am Kristof' ...still I show no signs of recognition... 'Van Laerhoven'... I must have blushed! The other 'student' was our keynote speaker. I had the mental model of those two guys being so young...
After the intensive workshop, we had a very nice workshop dinner. Thanks for Sozo for organizing it!

We met Jonna Häkkilä's student Paula Roinesalo from the University of Lapland and they won the Design Jury Award for Aesthetics prize. I put a picture of Paula on twitter under tag #ISWC2016. Congrats again for the team!

2016/07/29, Big Data Processing course

We got a lot of feedback from our students regarding the course Big Data Processing and Applications targeted for master's students, both positive and negative. There was also a comment that this course was the lousiest course the student had ever participated. I am truly sorry about that and we will make an effort to improve. Some students on the other hand felt that they enjoyed the course and many students participated actively in the discussions during the sessions.

We had made a decision that we will not use exams for evaluation but the performance of the students would be graded by their personal seminar presentation and report and also by a group project work. Immediately after the course started, we faced some problems. The schedule assessed for the seminars was very difficult to fill as there were so many students compared to last years. The decision that each student would have a personal seminar presentation turned out to be quite bad as almost all lecture sessions needed to be filled by student presentations. We had four presentations each session and no lectures from the teacher at all. Therefore, too many topics was left for self-studying. We could have used a learning diary and give home-work for the topics after each lecture and for next year this will be considered in addition to making the seminar also as group work.

Some technical problems occurred, as well. The set up of the Amazon platform was delayed so the first practical sessions had to be used for setting up the clusters. We had a plan that the students could do it independently before the exercise sessions. Also, the assignment for project works should have been given earlier for the students so they could have planned it more carefully.

Theo's lecture on Deep learning and IBM's Bluemix lecture were given very positive feedback so thanks for those!

2016/07/29, HASCA 2016

Thank you alla for submitting to HASCA 2016! We will have an excellent program at Ubicomp 2016 so see you in Heidelberg!

2016/03/16, Cyclist-Aware Traffic Lights

Our researchers Theodoros Anagnostopoulos and Denzil Ferreira have created a very cool system into our smart city Oulu: Cyclist-Aware Traffic Lights! Their system performs time-of-arrival estimation to the nearest traffic light and it is based on a distributed smartphone sensing approach. Please read the slide set Theodoros is kindly sharing with you.

2016/03/15, Big Data Processing and Application course started

Today, I started the lectures of the advanced course 521283S on Big Data Processing and Applications for master's students. The students would find information about Big Data 3V's, cloud computing, Apache Hadoop and its components, and other interesting things about the Big Data Processing pipeline. The students will have to set up their own Hadoop cluster (Cloudera distribution) on top of Amazon in the exercises - this idea was initally suggested by Matti Vakkuri, Tieto Big Data director. The course also includes seminars upon selected topics. On 31st March we get a visiting lecture from IBM and there we study the secrets of their Bluemix platform.

2015/10/08, Strata+Hadoop World

Our proposal from Data to Intelligence project Traffic Ecosystem work was selected as the first Finnish presentation ever in Strata+Hadoop World. There were hundreds of people participating and top-notch Big Data companies presenting their impressive portfolios. I will write more about the event soon when I will find the time. But... what's with me and electricity.. during my presentation, the electricity went down. Presentation is available.

2015/09/08, Hasca 2015

For the third time, we held our International Workshop on Human Activity Sensing Corpus and its Application in conjunction with Ubicomp/ISWC. The equipment to collect data have advanced considerably during the last ten years, but still the reasoning based on higher level contexts is a good research topic. Thanks for all the presenters and especially for our active organizer Nobuo Kawaguchi from Nagoya University.

2015/08/06, Back to work

Our workshop IWWISS 2015 in Coimbra started as the darkest workshop ever. However, we could start with our keynote speaker Fahim Kawsar in another facility nearby and were rescued from the lack of electricity. The whole program can be found from the workshop web page and the publications are included in the official Mobiquitous 2015 proceedings. Thanks for all participants for the presentations and lively discussions!

And for some good news - I will be presenting our research on Big Data in the beginning of October at Strata+Hadoop World 2015 in New York! A more detailed topic is given here. I am surely exited!

2015/03/26, IWWISS2015 CFP Open!

Please submit to our workshop in conjunction with Mobiquitous 2015 in Portugal! International Workshop on Web Intelligence and Smart Sensing.

2015/02/11, J. Transportation Research part C accepted our paper

Our PhD student Ekaterina Gilman just got a paper accepted to the Journal of Transportation Research part C. Her article presents a recommendation system for individual drivers she has built in the Digile Ltd's D2I program. The novelty of her approach is in fusing the real time traffic fluency, weather, spatial databases and the vehicle engine data with different kinds of machine learning models to predict the fuel consumption (or whatever cost the driver is interested in) of the vehicle. This prediction is monitored against a larger group's, as well as the driver's own past driving behavior, and suggestions for better driving can be given. I am happy to co-author this work as a role of a supervisor of the team.

2014/01/29, Oulu University RAE2013 (Research Assessment Exercise) published

The Oulu University Research Assessment Exercise Report 2014 - International Evaluation of Research at the University of Oulu was released yesterday. The evaluation is targeted to research communities (consortia of 15-120 persons, consisting of several research groups) which are formed on the basis of collaboration in research and doctoral training. It is not compulsory to attend the evaluation, but it is always good to have an outsider evaluation when you perform research as this information can be used as a reference when applying funding and forming new collaboration.

There were three categories in the evaluation: veni, vidi, vici; beginner groups, groups on the threshold of international breakthrough and world class research groups, respectively. My research group, iSpaces, was evaluated in the category of vidi within the iUBI consortia.
