The effect of generic headphone compensation on binaural renderings

Audio Engineering Society (AES)

In this study, the effects of generic headphone equalization in binaural rendering are evaluated objectively and subjectively, with respect to unequalized and individually-equalized cases.

Evaluation of real-time sound propagation engines in a virtual reality framework

AES International Conference on Immersive and Interactive Audio

Sound propagation in an enclosed space is a combination of several wave phenomena, such as direct sound, specular reflections, scattering, diffraction, or air absorption, among others. Achieving realistic and immersive audio in games and virtual reality (VR) requires real-time modeling of these phenomena.

The Effect of Hand Size and Interaction Modality on the Virtual Hand Illusion

IEEE Conference on Virtual Reality

In this paper, we consider how concepts related to the virtual hand illusion, user experience, and task efficiency are influenced by variations between the size of a user’s actual hand and their avatar’s hand.

On the Pitfalls of Measuring Emergent Communication

ArXiv

In this paper, we examine a few intuitive existing metrics for measuring communication, and show that they can be misleading. Specifically, by training deep reinforcement learning agents to play simple matrix games augmented with a communication channel, we find a scenario where agents appear to communicate (their messages provide information about their subsequent action), and yet the messages do not impact the environment or other agent in any way.

Convolutional neural networks for mesh-based parcellation of the cerebral cortex

Medical Imaging with Deep Learning (MIDL)

We show experimentally on the Human Connectome Project dataset that the proposed graph convolutional models outperform current state-of-the-art and baselines, highlighting the potential and applicability of these methods to tackle neuroimaging challenges, paving the road towards a better characterization of brain diseases.

Stochastic Adaptive Neural Architecture Search for Keyword Spotting

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)

We propose a new method called SANAS (Stochastic Adaptive Neural Architecture Search) which is able to adapt the architecture of the neural network on-the-fly at inference time such that small architectures will be used when the stream is easy to process (silence, low noise, …) and bigger networks will be used when the task becomes more difficult.

BOLT: A Practical Binary Optimizer for Data Centers and Beyond

International Symposium on Code Generation and Optimization (CGO)

In this paper, we present BOLT, a post-link optimizer built on top of the LLVM framework. Utilizing sample-based profiling, BOLT boosts the performance of real-world applications even for highly optimized binaries built with both feedback-driven optimizations (FDO) and link-time optimizations (LTO).
