This is the personal web page of Mats Sjöberg. I live in Espoo, Finland together with my wife and son. I like reading, walking and programming. I care about social and economic justice.

I work as a Machine learning specialist at CSC. I received my doctoral degree in computer science from Aalto University in 2014, and I’m particularly interested in deep learning and computer vision.

Software

Here are links to some free and open source software I have created, some professionally and some in my free time.

DeepCaption is an image captioning framework based on deep learning. It uses the PyTorch platform, and was created while I was working at Aalto University.
Digital Me (DiMe) – the idea of DiMe was to collect your personal data from various loggers into a central place that you control. The focus is on tracking knowledge work and developing applications that can help the knowledge worker manage their working life better. Created while working at the University of Helsinki.
Pair annotate is a web-based tool for performing pair-wise annotation of multimedia (videos or images), used in several MediaEval tasks.

Yaics is a simple GNU Social client in C++ and Qt. Since November 2014 Stig Atle Steffensen took over as maintainer of the project.
