Über mich
My work focuses on a specific structural feature: whether a signal contains two distinct frequency peaks separated by a valley. Standard methods — power spectrum, coefficient of variation, sample entropy, and coherence — do NOT detect this. I built anchor_score to fill that gap. Published preprints (10 on ORCID):(DOI: 10.5281/zenodo.22850972) Validated on: - Synthetic signals of known structure - LIGO O1/O4c1 gravitational-wave detector noise - 24-subject meditation EEG dataset (OpenNeuro ds001787) does your signal contain hidden structure that conventional methods miss?...

Developing model-free methods for spectral structure detection in single-channel time series. - Created anchor_score, a metric for detecting bimodal spectral structure - Validated on synthetic signals, LIGO O1/O4c1 data, and 24-subject meditation EEG dataset (OpenNeuro ds001787) - Published three preprints on Zenodo - Providing analysis services through Zinn Hub
