SymCHM - the compositional hierarchical model for symbolic music representations November 5, 2017

[Published paper] SymCHM—An Unsupervised Approach for Pattern Discovery in Symbolic Music with a Compositional Hierarchical Model

By

We are thrilled that a new paper on the Compositional Hierarchical Model has just been published. The paper describes a modified version of the model, SymCHM, capable of working with symbolic music representations. The paper describes the work done during the last year of the model development for the pattern discovery task. The paper publicly available here: http://www.mdpi.com/2076-3417/7/11/1135 We are also…

[Published paper] The Moodo dataset: Integrating user context with emotional and color perception of music for affective music information retrieval

By

My colleagues and I have recently published a new scientific paper which presents the Moodo dataset and performs a detailed analysis of the multimodal data. The dataset includes user background data along with music preferences and music knowhow. In an attempt to show the future development of the recommender systems in general, we have applied a data fusion model which models…

Faculty Days – Minecraft Workshop

By

Last week the Faculty hosted about 400 elementary-school children who visited our laboratories and observed our latest projects. We also prepared several workshops, focusing on game-based learning, ranging from and algorithmic thinking to programming. Our Lab prepared the Minecraft workshop, using the Minecraft Education Edition and Code Connection software to support scratch-like programming in Minecraft. The workshop was a brief version…

Roland VK-7 sticky keys red glue problem – solved

By

About two years ago I bought a nice sounding Roland VK-7. The keyboard was in nice shape – however, it did develop (or had previously) a few flaws during the last year. The first problem (which I also informed of by the previous owner) was a random reset of the whole keyboard. After googling about similar problems other VK-7 owners had,…

Hammond XB-2 – the conclusion

By

Dejan and I have finally managed to perform one last attempt to fix the Hammond XB-2. As said in my previous blog post, the XB-2 I bought had an interesting distorted sound problem. This is a video of the sound problem: We tried a number of things, including the DRAM swap. Today, we performed the SRAM swap. Since we were not able to obtain…

Moodo dataset – Mood, Colors and Music in Music Information Retrieval (2013 – today)

By

Since 2013, I have also been involved in a study trying to determine whether there is a distinctive interrelationship between user’s mood, their perception of colors and their influence on the perception of music, especially in terms of the perceived and induced emotions. We published several conference papers including a paper at ISMIR 2014. Along with the study, we gathered a significant…

[Published paper] A different white-box deep architecture? Is it possible?

By

I recently published a paper more thoroughly explaining what I have been developing as a part of my PhD research at the Laboratory for Computer Graphics and Multimedia, Faculty of Computer and Information Science. The paper describes an alternative deep architecture. Those of you who are involved in recent machine learning research probably know neural-network-based deep architectures, which recently gained…

Hello blog!

By

It has been at least about 4 years since I renovated my blog. The time has come to let the old wordpress blog (here) die away. This time, the content is more focused on my research in the music information retrieval field and my other work in software development, new technologies and music. If interested, my old blog is still available at…

Fixing Hammond XB-2

By

A few weeks ago Dejan and I began our work on Hammond XB-2 again. The current problem can be heard here: We tracked the problem back to the static RAMs, which was also mentioned as a solution in one of the comments on this similar youtube video. We opened the keyboard and took out the main board. As you can…

Laboratory for computer graphics and multimedia has a new website

By

We are proud to present a new website of our beloved Laboratory. Visit the website! 🙂 Although we all loved (the status quo of) our previous website, it’s been the same for almost 10 years. The new website (found at http://musiclab.si and http://lgm.fri.uni-lj.si) is now finally up-to-date with our newest projects, publications and research interests. You’re welcome to visit, if not for…
