We thank Marcus Motz from Develogic Hamburg, Germany for his efforts to design and construct the borehole plug.
We are also thankful for the support of proponents of Atlantis Massif drilling who were unable to participate in the expedition: The International Ocean Discovery Program IODP represents the latest incarnation of almost five decades of scientific ocean drilling excellence and is generally accepted as the most successful international collaboration in the history of the Earth sciences.
IODP builds seamlessly on the accomplishments of previous phases: As in the preceding Integrated Ocean Drilling Program, expeditions in the new IODP are conducted by three implementing organizations, each providing a different drilling capability.
Scheduling decisions for each capability are made by three independent Facility Boards, each of which includes scientists, operators, and platform funding partners: The new IODP differs from prior scientific ocean drilling programs in that it has neither a central management organization nor commingled funding for program-wide activities. Yet, this phase of IODP retains a fundamental integrative structural element: International scientists may submit drilling proposals to the Science Support Office; all submitted proposals are then evaluated by a Science Evaluation Panel in the context of the Science Plan.
The new IODP also has a second internationally integrative level for high-level discussion and consensus-building: The Forum is charged with assessing program-wide progress toward achieving the Science Plan. This enhanced membership in the new IODP represents a remarkable level of international collaboration that remains one of the greatest ongoing strengths of scientific ocean drilling. In this paper we describe a way to predict ad quality using hand-crafted, interpretable acoustic features that capture timbre, rhythm, and harmonic organization of the audio signal.
We then discuss how the characteristics of the sound can be connected to concepts such as the clarity of the ad and its message. Prockup is currently a scientist at Pandora working on methods and tools for Music Information Retrieval at scale.

Since we cannot afford to burden an individual hearing aid user with the task to collect a large acoustic database, we will want to train an acoustic scene classifier on one in-situ recorded waveform of a few seconds duration per class. In this paper we develop a method that achieves high levels of classification accuracy from a single recording of an acoustic scene.
Channing Moore, Rif A. Our goal is to learn semantically structured audio representations without relying on categorically labeled data. We consider several class-agnostic semantic constraints that are inherent to non-speech audio: We apply these constraints to sample training data for triplet-loss embedding models using a large unlabeled dataset of YouTube soundtracks. The resulting low-dimensional representations provide both greatly improved query-by-example retrieval performance and reduced labeled data and model complexity requirements for supervised sound classification.
Cost-sensitive detection with variational autoencoders for environmental acoustic sensing slides , BibTeX. Environmental acoustic sensing involves the retrieval and processing of audio signals to better understand our surroundings. While large-scale acoustic data make manual analysis infeasible, they provide a suitable playground for machine learning approaches. Most existing machine learning techniques developed for environmental acoustic sensing do not provide flexible control of the trade-off between the false positive rate and the false negative rate.
This paper presents a cost-sensitive classification paradigm, in which the hyper-parameters of classifiers and the structure of variational autoencoders are selected in a principled Neyman- Pearson framework. We examine the performance of the proposed approach using a dataset from the HumBug project1 which aims to detect the presence of mosquitoes using sound collected by simple embedded devices. Machine learning and audio signal processing: State of the art and future perspectives.
How can end-to-end audio processing be further optimized? How can an audio processing system be built that generalizes across domains, in particular different languages, music styles, or acoustic environments?
How can complex musical hierarchical structure be learned? How can we use machine learning to build a music system that is able to react in the same way an improvisation partner would? Can we build a system that could put a composer in the role of a perceptual engineer? Sepp Hochreiter has made numerous contributions in the fields of machine learning and bioinformatics.

Bitwise Source Separation on Hashed Spectra: This paper proposes an efficient bitwise solution to the single-channel source separation task.
Most dictionary-based source separation algorithms rely on iterative update rules during the run time, which becomes computationally costly especially when we employ an overcomplete dictionary and sparse encoding that tend to give better separation results.
To avoid such cost we propose a bitwise scheme on hashed spectra that leads to an efficient posterior probability calculation. For each source, the algorithm uses a partial rank order metric to extract robust features that form a binarized dictionary of hashed spectra.
This simple voting-based dictionary search allows a fast and iteration-free estimation of ratio masking at each bin of a signal spectrogram.
To our knowledge, this is the first dictionary based algorithm for this task that is completely iteration-free in both training and testing.
We present Bitwise Neural Networks BNN as an efficient hardware-friendly solution to single-channel source separation tasks in resource-constrained environments. Thanks to the fully bitwise run-time operations, the BNN system can serve as an alternative solution where efficient real-time processing is critical, for example real-time speech enhancement in embedded systems. Furthermore, we also propose a binarization scheme to convert the input signals into bit strings so that the BNN parameters learn the Boolean mapping between input binarized mixture signals and their target Ideal Binary Masks IBM.
Experiments on the single-channel speech denoising tasks show that the efficient BNN-based source separation system works well with an acceptable performance loss compared to a comprehensive real-valued network, while consuming a minimal amount of resources. Current biological understanding of neural encoding suggests that phase information is preserved and utilized at every stage of the auditory pathway. However, current computational approaches primarily discard phase information in order to mask amplitude spectrograms of sound.
In this paper, we seek to address whether preserving phase information in spectral representations of sound provides better results in monaural separation of vocals from a musical track by using a neurally plausible sparse generative model. Our results demonstrate that preserving phase information reduces artifacts in the separated tracks, as quantified by the signal to artifact ratio GSAR. Furthermore, our proposed method achieves state-of-the-art performance for source separation, as quantified by a mean signal to interference ratio GSIR of Today, the optimal performance of existing noise-suppression algorithms, both data-driven and those based on classic statistical methods, is range bound to specific levels of instantaneous input signal-to-noise ratios.
In this paper, we present a new approach to improve the adaptivity of such algorithms enabling them to perform robustly across a wide range of input signal and noise types.
Our methodology is based on the dynamic control of algorithmic parameters via reinforcement learning. Specifically, we model the noise-suppression module as a black box, requiring no knowledge of the algorithmic mechanics except a simple feedback from the output.
We utilize this feedback as the reward signal for a reinforcement-learning agent that learns a policy to adapt the algorithmic parameters for every incoming audio frame 16 ms of data. While deep neural networks have shown powerful performance in many audio applications, their large computation and memory demand has been a challenge for real-time processing. In this paper, we study the impact of scaling the precision of neural networks on the performance of two common audio processing tasks, namely, voice-activity detection and single-channel speech enhancement.
Through experiments conducted with real user data, we demonstrate that deep neural networks that use lower bit precision significantly reduce the processing time up to 30x. Nontrivial connectivity has allowed the training of very deep networks by addressing the problem of vanishing gradients and offering a more efficient method of reusing parameters.
