T1: Bayes and Markov Listen to Music
Music is a very complex signal with information spread across different hierarchical levels and temporal scales. In the last 15 years in the field of Music Information Retrieval (MIR) and Music Signal Processing there has been solid progress in developing algorithms for understanding music signals with applications such as music recommendation, classification, transcription and visualization. Probabilities and probabilistic modeling play an important role in many of these algorithms. The goal of this tutorial is to explore how probabilistic reasoning is used in the analysis of music signals.
The target audience is researchers and students interested in MIR but the tutorial would also be of interest to participants from other areas of signal processing as the techniques described have a wide variety of applications. More specifically the tutorial will cover how basic discrete probabilities can be used for symbolic music generation and analysis, followed by how classification can be cast as a probability density function estimation problem through Bayes theorem. Automatic chord detection and structure segmentation will be used as a motivating problems for probabilistic reasoning over time and Hidden Markov Models more specifically. Kalman and particle filtering will be described through real-time beat tracking and score following. More complex models such as Bayesian Networks and Conditional Random Fields and how the can be applied for music analysis will also be presented. Finally the tutorial will end with Markov Logic Networks a formalism that subsumes all previous models. Through the tutorial the central concepts of Bays Theorem, Markov assumptions and maximum likelihood estimation and expectation maximization will be described.

T2: Leveraging MIDI files for Music Information Retrieval
MIDI files are a widely-available digital score format which contain a bounty of valuable information about a given piece of music. A MIDI file which has been matched to a corresponding audio recording can provide a transcription, key and meter annotations, and occasionally lyrics for the recording. They are also useful in very large-scale metadata-agnostic corpus studies of popular music. Despite their potential utility, they remain underused in the music information retrieval community. The purpose of this tutorial is to expose attendees to the promise of leveraging MIDI files in MIR tasks.
The motivation for having this tutorial now is the release of the Lakh MIDI Dataset (LMD), a collection of 178,561 MIDI files of which many have been matched and aligned to corresponding entries in the Million Song Dataset. The tutorial will therefore include a mix of explanatory sessions on research involving MIDI files and hands-on demonstrations of utilizing the LMD. Attendees will leave the tutorial with a strong awareness of what MIDI files are, what sort of information we can extract from them, what steps are necessary for leveraging this information, practical knowledge of how to utilize MIDI files, and an idea of tantalizing prospects for future research.

Prior to his PhD, he completed a Master’s at the Center for Computer Research in Music and Acoustics and a Bachelor’s at Oberlin College.
T3: A basic introduction to audio-related music information retrieval
The main goal of this tutorial is to give an introduction to Music Information Retrieval with a particular focus on audio-related analysis and retrieval tasks. Well-established topics in MIR are selected to serve as motivating application scenarios. Within these scenarios, fundamental techniques and algorithms that are applicable to a wide range of analysis and retrieval problems are presented in depth. Including numerous figures and sound examples, this tutorial is intended to suite for a wide and interdisciplinary audience with no particular background in MIR or audio processing. This tutorial consists of eight parts, each lasting between 20 and 25 minutes. The first two parts cover fundamental material on music representations and the Fourier transform—concepts that are required throughout the tutorial. In the subsequent parts, concrete MIR tasks serve as starting points for our investigations. Each part starts with a general description of the MIR scenario at hand and integrates the topic into a wider context. Motivated by a concrete scenario, each part discusses important techniques and algorithms that are generally applicable to a wide range of analysis, classification, and retrieval problems.

T4: So you want to conduct a user study in MIR?
This tutorial will consist of three main parts. In the first one, we will provide an overview of the user studies in the ISMIR community as well as in other domains such as psychology, music sociology, musicology, library and information science, and HCI, highlighting the important scholars and summarizing the major themes. In the second part, we will present an overview of the different user research methods. We will cover the commonly used methods in social science research (e.g., interviews, surveys, focus groups, written/audio journals, task-based experiments, tracking biological data, etc.), discuss the suitability of each method for different research projects, and the strengths and weaknesses of each method.
The third part will consist of an interactive session during which the participants will be invited to brainstorm research questions that are relevant to their own MIR research projects and could be answered by conducting an interdisciplinary user study. Individual participants or group of participants will present their ideas and they will receive feedback from the presenters as well as from other participants.

T5: Machine-Learning for Symbolic Music Generation
The goal of this tutorial is to present in a comprehensive way the challenges and techniques of using computers for generating musical content. Various kind of techniques will be considered from Markov models to deep learning models, with the goal of presenting both the state of the art and the current limitations and open problems. The tutorial will cover essentially symbolic music generation, with an emphasis on leadsheets, seen as the primary form of mainstream music, as well as polyvocal music.
We will cover two classes of models: Markov models, and in particular Markov Constraints models, which have been particularly successful at modeling monophonic material as well as leadsheets. We’ll describe the underlying models that can be learned efficiently, and will illustrate them with many examples of generated music in various styles.
We will also cover deep learning models and application to polyvocal music. After reviewing the basic components of deep architectures (neural layers, autoencoders, recurrent networks…), we will describe how they can be used in a direct way, e.g., to produce musical accompaniment, or in a more indirect way (by controlling sampling or unit selection and aggregation, etc.) for a finer control of generation. Various examples of architectures, experiments and approaches will be analyzed and compared.
