Current machine learning (ML)-based algorithms for filtering electroencephalography (EEG) time series data face challenges related to cumbersome training times, regularization, and accurate reconstruction. To address these shortcomings, we present an ML filtration algorithm driven by a logistic covariance-targeted adversarial denoising autoencoder (TADA). We hypothesize that the expressivity of targeted, correlation-driven convolutional will enable effective while minimizing compute...

Brain-computer interfaces (BCIs) offer transformative potential, but decoding neural signals presents significant challenges. The core premise of this paper is built around demonstrating methods to elucidate the underlying low-dimensional geometric structure present in high-dimensional brainwave data order assist downstream BCI-related classification tasks. We demonstrate two pipelines related electroencephalography (EEG) signal processing: (1) a preliminary pipeline removing noise from...

Electromyogenic (EMG) noise is a major contamination source in EEG data that can impede accurate analysis of brain-specific neural activity. Recent literature on EMG artifact removal has moved beyond traditional linear algorithms favor machine learning-based systems. However, existing deep filtration methods often have large compute footprints and prohibitively long training times. In this study, we present new system for filtering interference from using an autoencoder-targeted adversarial...

We present recent progress in calculating the semileptonic form factors $h_{A_1}(w)$ for $\bar{B} \to D^{\ast} \ell \bar{\nu}$ decays. use Oktay-Kronfeld (OK) action charm and bottom valence quarks HISQ light quarks. adopt Newton method combined with scanning to find a good initial guess $\chi^2$ minimizer fitting of 2pt correlation functions.

We present our preliminary results on the machine learning estimation of $\text{Tr} \, M^{-n}$ from other observables with gradient boosting decision tree regression, where $M$ is Dirac operator. Ordinarily, obtained by linear CG solver for stochastic sources which needs considerable computational cost. Hence, we explore possibility cost reduction trace adoption algorithm. also discuss effects bias and its correction.
