Spontaneous music : the first generation British free improvisers
No full textThe British free improvisation scene originated in London and Sheffield during the
mid 1960s. In groups such as AMM, the Spontaneous Music Ensemble and Joseph
Holbrooke, a distinctive and ambitious musicality developed that still occupies most
of its protagonists forty years later.
Marked stylistic contrasts developed within the genre, notably the `atomistic' and
`laminar' methods of interaction. Nonetheless, a consistency of principle and practice
was also apparent that defined British free improvisation as unique. In some respects
the genre resembled its German, Dutch and American counterparts, and also the jazz
and classical avant-gardes that had inspired them. Both conceptually and practically,
however, clear differences remained.
The British free improvisers refined a method and an aesthetic of musical creativity,
which suggested an intimate perspective and a detailed analysis of that which we
accept as `music'. Its techniques and results were unconventional, but remained
consistent with music's defining concepts and experiences. As such, British free
improvisation suggested a more inclusive model of musicality than is common, and
implied a broad critique of the cultural values that define `music' at all. Though the
free improvisers themselves did not explicitly state the connection, their work may be
viewed in the context of Deconstruction: the post-structuralist analytical strategy
associated with philosopher Jacques Derrida.
British free improvisation culminated from innovations within the twentieth century
avant-garde. Referencing styles such as atonality and free jazz, it challenged the
aesthetic, technical and hierarchical standards of Western tradition in a form that was
striking and extreme, but also of logical development and focus. Free improvisation
owed explicit debt to a variety of other musics; its most singular achievement
however, was the redefinition of `rhythm' by which it disguised this fact.
The music of the first generation British free improvisers is reliant upon precise
conceptual and practical execution. But though this has enabled the genre to be
musically innovative, in the long term it has also become a logical problem. With
British free improvisation as its subject, the scrutiny of Deconstruction reveals
significant discrepancies between what `free improvisation' implies and what it
actually represents
A Return to the Future or Forward to the Past?
No full textThis article traces the literary origins of the 1945 'zero hour' concept and explores its relation and importance to post-war avant-garde music, as well as the power of its concomitant polemics. The apparent hegemony of the resulting total serialist music and its associated ideas of newness and history are questioned and then compared to the reaction against it in the 1960s, when radical ideas about man's relationship with, and understanding of, time and history grew. It is suggested that the real break with the past began then rather than in the immediate post-war period
Metadata Representations for Queryable ML Model Zoos
No full textMachine learning (ML) practitioners and organizations are building model zoos of pre-trained models, containing metadata describing properties of the ML models and datasets that are useful for reporting, auditing, reproducibility, and interpretability purposes. The metatada is currently not standardised; its expressivity is limited; and there is no interoperable way to store and query it. Consequently, model search, reuse, comparison, and composition are hindered. In this paper, we advocate for standardized ML model metadata representation and management, proposing a toolkit supported to help practitioners manage and query that metadata.Web Information SystemsHuman-Centred Artificial Intelligenc
A Manifesto of Nodalism
No full textThis paper proposes the notion of Nodalism as a means describing contemporary culture and of understanding my own creative practice in electronic music composition. It draws on theories and ideas from Kirby, Bauman, Bourriaud, Deleuze, Guatarri, and Gochenour, to demonstrate how networks of ideas or connectionist neural models of cognitive behaviour can be used to contextualize, understand and become a creative tool for the creation of contemporary electronic music
Optimizing ML Inference Queries Under Constraints
No full textThe proliferation of pre-trained ML models in public Web-based model zoos facilitates the engineering of ML pipelines to address complex inference queries over datasets and streams of unstructured content. Constructing optimal plan for a query is hard, especially when constraints (e.g. accuracy or execution time) must be taken into consideration, and the complexity of the inference query increases. To address this issue, we propose a method for optimizing ML inference queries that selects the most suitable ML models to use, as well as the order in which those models are executed. We formally define the constraint-based ML inference query optimization problem, formulate it as a Mixed Integer Programming (MIP) problem, and develop an optimizer that maximizes accuracy given constraints. This optimizer is capable of navigating a large search space to identify optimal query plans on various model zoos.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Web Information SystemsHuman-Centred Artificial Intelligenc

No full textBuilding a generalisable ML pipeline at ING
No full textAdvances in data science have caused an increase in the use of Artificial Intelligence (AI), specifically Machine Learning (ML), throughout various fields. Not only in research but in the industry as well, has ML been receiving increasing amounts of interest. Many companies rely on ML models to increase the efficiency of existing processes or offer new services and products. The industry, however, is facing several additional challenges compared to the academic context. One of those challenges is applying the Development Operations (DevOps) model to an ML application, also referred to as MLOps. This thesis sets out to find the specific challenges that practitioners encounter while operationalising ML models. To do so, we perform a single-case case study on an ML pipeline built by the Trade & Communication Surveillance team at the ING bank. This case study consists of conducting a set of interviews and performing a manual code inspection of the pipeline. The team faces challenges ranging from having insufficient time for operationalising each ML project individually to operating in the highlyregulated fintech context. Their pipeline is able to deploy a single ML model but it does not generalise well to other projects. We present the first version of an application that mitigates these challenges. The application is able to deploy ML models to the development environment at ING and can be operated by data scientists to reduce the effort of operationalising an ML model.

'Project smells' - Experiences in Analysing the Software Quality of ML Projects with mllint
No full textMachine Learning (ML) projects incur novel challenges in their development and productionisation over traditional software applications, though established principles and best practices in ensuring the project's software quality still apply. While using static analysis to catch code smells has been shown to improve software quality attributes, it is only a small piece of the software quality puzzle, especially in the case of ML projects given their additional challenges and lower degree of Software Engineering (SE) experience in the data scientists that develop them. We introduce the novel concept of project smells which consider deficits in project management as a more holistic perspective on software quality in ML projects. An open-source static analysis tool mllint was also implemented to help detect and mitigate these. Our research evaluates this novel concept of project smells in the industrial context of ING, a global bank and large software- and data-intensive organisation. We also investigate the perceived importance of these project smells for proof-of-concept versus production-ready ML projects, as well as the perceived obstructions and benefits to using static analysis tools such as mllint. Our findings indicate a need for context-aware static analysis tools, that fit the needs of the project at its current stage of development, while requiring minimal configuration effort from the user.

Audiomobiles, Sculptures and Conundrums
No full textRoberto Gerhard was a pioneer of electronic music in England creating a number of substantial concert, theatre and radio works from as early as 1954. Gerhard’s electronic music is one of the richest repositories for understanding the development of the composer’s late compositional technique. Apart from the Symphony no.3, ‘Collages’, none of Gerhard’s electronic music is published. This paper will discuss aspects of Gerhard’s electronic music, focusing on Audiomobiles (1958-59) and Sculptures (1963)
In vitro oocyte maturation, fertilization, and culture after laparoscopic ovum pick-up in an endangered gazelle (Gazella dama mhorr)
No full textThe recovery of immature oocytes followed by in vitro maturation, fertilization and culture (IVMFC) allows the rescue of biological material of great genetic value for the establishment of genetic resource banks. Studies have been carried out on endangered Mohor gazelle sperm cryopreservation (Garde et al. 2003 Biol. Reprod. 69, 602-611), but there are no studies on oocytes in this species. The purpose of this work was to develop a protocol for ovarian stimulation for the recovery of oocytes and subsequent IVMFC. The study was conducted using six reproductively mature female Mohor gazelles from the breeding herd at the Estacion Experimental de Zonas Aridas. Animals were synchronized by insertion of controlled progesterone internal drug release (CIDR) devices for 14 days and removal of the devices on the day of ovum pickup (OPU). Follicular growth was stimulated by a total of 5.28 mg of oFSH (Ovagen, ICP, Auckland, New Zealand) given in four equal doses every 12 h. OPUs were performed (Berlinguer et al. 2004 Theriogenology 61, 1477-1486) on Day 15 from the beginning of treatment, and follicles were aspirated with a syringe and a 25G needle using TCM199-HEPES with 50 1⁄4g/mL streptomycin, 50 IU/mL penicillin, 0.1% polyvinyl alcohol, and 15 IU/mL heparin. Degenerated oocytes and those with expanded cumulus were removed. Oocytes were cultured in TCM-199 plus 10% FCS, 10 1⁄4g/mL ovine FSH/LH, 1 1⁄4g/mL estradiol, and 0.1 mg/mL glutamine at 38.5°C under 5% CO2/air and maximum humidity. Spermatozoa were cryopreserved in Tes-Tris with 5% egg yolk and 6% glycerol, and selected by swim-up in SOF medium. After 24 h sperm-oocyte coincubation (sperm concentration: 1 × 106/mL) in SOF with 2% estrus sheep serum under 5% CO2 5% O2 90% N2, presumptive zygotes were transferred to SOF with 0.4% BSA and amino acids under 5% CO2, 5% O2 90% N2 and cultured for 4 days. Oocytes and embryos were stained with Hoechst 33342 and propidium iodide (1 1⁄4g/mL each) and visualized under a fluorescence microscope. A total of 35 oocytes were recovered from 56 punctured follicles (62.5%). This recovery rate was similar to those in wildlife in earlier reports, but more studies are needed to improve hormonal stimulation and oocyte harvesting. Out of 29 cumulus-oocyte complexes matured in vitro, 3.5% were found at GV and 6.9% at MI; 20.7% were degenerated and 68.9% had advanced to MII. Fertilization and cleavage rates were 40% and 30%, respectively, of matured oocytes. Out of eight zygotes, six showed cleavage (ranging from 2 to 8 cells). None of the developing embryos progressed to the blastocyst stage, suggesting the existence of a developmental block and the need to improve culture conditions. Although more trials will help to improve IVMFC, this study demonstrates for the first time the feasibility of in vitro fertilization with frozen-thawed semen of in vitro matured oocytes collected by OPU from FSH-stimulated endangered gazelles
