Computer Science
Computation and Language
Writing systems of Indic languages have orthographic syllables, also known as
complex graphemes, as unique horizontal units. A prominent feature of these
languages is these complex grapheme units that comprise consonants/consonant
conjuncts...
Multi-level Temporal-channel Speaker Retrieval for Zero-shot Voice

Sound
Zero-shot voice conversion (VC) converts source speech into the voice of any
desired speaker using only one utterance of the speaker without requiring
additional model updates. Typical methods use a speaker representation from a
pre-trained...
Solution of the Hurwitz problem with a length-2 partition

Geometric Topology
In this note we provide a new partial solution to the Hurwitz existence
problem for surface branched covers. Namely, we consider candidate branch data
with base surface the sphere and one partition of the degree having length two,
and we fu...
Quantum-enhanced optical phase-insensitive heterodyne detection beyond

Quantum Physics
Optical phase-insensitive heterodyne (beat-note) detection, which measures
the relative phase of two beams at different frequencies through their
interference, is a key sensing technology for various spatial/temporal
measurements, such as f...
An Adaptive Graduated Nonconvexity Loss Function for Robust Nonlinear
Least Squares Solutions

Computer Science
Robotics
Many problems in robotics, such as estimating the state from noisy sensor
data or aligning two point clouds, can be posed and solved as least-squares
problems. Unfortunately, vanilla nonminimal solvers for least-squares problems
are notorio...

Neurons and Cognition
Several authors have recently highlighted the need for a new dynamical
paradigm in the modelling of brain working and evolution. In particular, the
models should include the possibility of non constant and non symmetric
synaptic weights $T_...
