Two-Level Softmax Sampling Done Right: Correcting Bias from Size Imbalance and Dispersion
Walid Bendada, Guillaume Salha-Galvan
Sampling from a softmax distribution is a fundamental operation in machine learning, but its linear complexity in the number of items makes exact sampling impractical at scale. Two…
Asymptotic hydrographs and anomalous dispersion in mass-conserving storage cascades
Henrique Santos Lima, Márk Honti, Balázs Sándor
Sums of independent exponential random variables lead to the Erlang distribution, providing a direct probabilistic route from exponential waiting times to the integer-shape gamma l…
A spectral model of power-law decay in natural and engineered systems
Balázs Sándor, Márk Honti, Henrique Santos Lima
We present a first-principles spectral mechanism for the emergence of nonextensive -exponential dilution and power-law relaxation in non-ideal transport systems. By modeling an…
Purification of a monitored qubit: exact path-integral solution
Matheus M. R. Poltronieri Martins, Henrique Santos Lima
We investigate the purification dynamics of a single qubit under continuous in time monitoring. By employing a collisional model framework where the system interacts sequentially w…
Brain criticality through nonadditive entropic analysis of electroencephalograms
Henrique Santos Lima, Constantino Tsallis, Dimitri M. Abramov
On the grounds of nonadditive entropies -- appropriate for complex systems -- we investigate the electroencephalogram amplitudes of typical and ADHD children. The corresponding pro…
Superstatistical Approach to Turbulent Circulation Fluctuations
Henrique S. Lima, Rodrigo M. Pereira, Luca Moriconi +2
Recent investigations of turbulent circulation fluctuations have uncovered substantial insights into the statistical organization of flow structures and revealed unexpected geometr…
Deep brain microelectrode signal: -statistical approach
Ana Luiza Souza Tavares, Henrique Santos Lima, Artur Pedro Martins Neto +2
We characterize the amplitude statistics of intraoperative microelectrode recordings (MERs) obtained during deep brain stimulation (DBS) surgery in 46 patients with Parkinson's dis…
Universal and non-universal facets of quantum critical phenomena unveiled along the Schmidt decomposition theorem
Samuel M. Soares, Lucas Squillante, Henrique S. Lima +2
Critical phenomena have been extensively investigated both theoretically and experimentally in many fields, such as condensed matter physics, biology, e.g., brain criticality, and…
