Consistency analysis of refined instrumental variable methods for continuous-time system identification in closed-loop

no code implementations13 Apr 2024 Rodrigo A. González, Siqi Pan, Cristian R. Rojas, James S. Welsh

In this paper, we address the consistency of the simplified refined instrumental variable method for continuous-time systems (SRIVC) and its closed-loop variant CLSRIVC when they are applied on data that is generated from a feedback loop.

Spatial HuBERT: Self-supervised Spatial Speech Representation Learning for a Single Talker from Multi-channel Audio

no code implementations17 Oct 2023 Antoni Dimitriadis, Siqi Pan, Vidhyasaharan Sethu, Beena Ahmed

Spatial HuBERT learns representations that outperform state-of-the-art single-channel speech representations on a variety of spatial downstream tasks, particularly in reverberant and noisy environments.

On the Relation between Discrete and Continuous-time Refined Instrumental Variable Methods

no code implementations31 May 2023 Rodrigo A. González, Cristian R. Rojas, Siqi Pan, James S. Welsh

The Refined Instrumental Variable method for discrete-time systems (RIV) and its variant for continuous-time systems (RIVC) are popular methods for the identification of linear systems in open-loop.

Parsimonious Identification of Continuous-Time Systems: A Block-Coordinate Descent Approach

no code implementations6 Apr 2023 Rodrigo A. González, Cristian R. Rojas, Siqi Pan, James S. Welsh

The identification of electrical, mechanical, and biological systems using data can benefit greatly from prior knowledge extracted from physical modeling.

A low latency attention module for streaming self-supervised speech representation learning

1 code implementation27 Feb 2023 Jianbo Ma, Siqi Pan, Deepak Chandran, Andrea Fanelli, Richard Cartwright

The SA represents our proposal for an efficient streaming SSRL implementation, while the LLSA solves the latency build-up problem of other streaming attention architectures, such as the masked acausal attention (MAA), guaranteeing a latency equal to one layer even when multiple layers are stacked.
