Sparse Head-Related Transfer Function Representation with Spatial Aliasing Cancellation

International Conference on Acoustics, Speech and Signal Processing

In this paper, a new technique to reconstruct high resolution individual HRTFs from sparse measurements is presented. This is achieved by minimizing the spatial aliasing error in the spherical harmonics (SH) representation of the HRTFs, and by incorporating statistics calculated from a set of reference HRTFs, leading to an optimal minimum mean-square error solution.

Learning Filterbanks from Raw Speech for Phone Recognition

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

We train a bank of complex filters that operates on the raw waveform and is fed into a convolutional neural network for end-to-end phone recognition.

Semi-Oblivious Traffic Engineering: The Road Not Taken

USENIX Symposium on Networked Systems Design and Implementation (NSDI)

This paper presents a system that uses a set of paths computed using Räcke’s oblivious routing algorithm, as well as a centralized controller to dynamically adapt sending rates. Although oblivious routing and centralized TE have been studied previously in isolation, their combination is novel and powerful.

DesIGN: Design Inspiration from Generative Networks

ArXive

Can an algorithm create original and compelling fashion designs to serve as an inspirational assistant? To help answer this question, we design and investigate different image generation models associated with different loss functions to boost creativity in fashion generation.

SmoothOperator: Reducing Power Fragmentation and Improving Power Utilization in Large-scale Datacenters

ASPLOS 2018

With the ever growing popularity of cloud computing and web services, Internet companies are in need of increased computing capacity to serve the demand. However, power has become a major limiting factor prohibiting the growth in industry: it is often the case that no more servers can be added to datacenters without surpassing the capacity of the existing power infrastructure.

A Social Haptic Device to Create Continuous Lateral Motion Using Sequential Normal Indentation

IEEE Haptics Symposium (HAPTICS)

This paper presents a device for creating a continuous lateral motion on the arm to mimic a subset of the gestures used in social touch.

Toward Improved Surgical Training: Delivering Smoothness Feedback using Haptic Cues

IEEE Haptics Symposium (HAPTICS)

In this paper, we explore the effectiveness of providing real-time feedback of movement smoothness, a characteristic associated with skilled and coordinated movement, via a vibrotactile cue. Subjects performed a mirror-tracing task that requires coordination and dexterity similar in nature to that required in endovascular surgery.

Design and Analysis of a High-Performance Impedance-Based Hybrid Haptic Interface

Haptics Symposium

This paper describes the design of a novel, high-performance one degree-of-freedom hybrid haptic interface. The interface integrates a particle brake, a Series Elastic Actuator (SEA), and a small DC motor into a single actuator. Unlike existing hybrid designs, the one presented here does not suffer from a significant mismatch between passive and active torque capability.

Randomized algorithms for distributed computation of principal component analysis and singular value decomposition

Advances in Computational Mathematics

Randomized algorithms provide solutions to two ubiquitous problems: (1) the distributed calculation of a principal component analysis or singular value decomposition of a highly rectangular matrix, and (2) the distributed calculation of a low-rank approximation (in the form of a singular value decomposition) to an arbitrary matrix.
