Overview of Siren
architecture that accurately represents the gradients of the signal, enabling its use to solve boundary
Implicitly defined, continuous, differentiable signal representations parameterized
by neural networks have emerged as a powerful paradigm, offering many possible
benefits over conventional representations.Further,
we show how SIREN s can be leveraged to solve challenging boundary value
problems, such as particular Eikonal equations (yielding signed distance functions),
the Poisson equation, and the Helmholtz and wave equations.However, current network architectures
for such implicit neural representations are incapable of modeling signals
with fine detail, and fail to represent a signal’s spatial and temporal derivatives,
despite the fact that these are essential to many physical signals defined implicitly
as the solution to partial differential equations.Lastly, we combine
SIREN with hypernetworks to learn priors over the space of SIREN functions.We analyze SIREN
activation statistics to propose a principled initialization scheme and demonstrate
the representation of images, wavefields, video, sound, and their derivatives.We propose to leverage periodic
activation functions for implicit neural representations and demonstrate that these
networks, dubbed sinusoidal representation networks or SIREN, are ideally suited
for representing complex natural signals and their derivatives.
SIREN is supported by a distributed community of water-dwelling creatures.

Did You Know?
The sirens were a group of partly human female creatures that lured sailors onto destructive rocks with their singing.Odysseus and his men encountered the sirens on their long journey home from Troy.The only way to sail by them safely was to make oneself deaf to their enchanting song, so Odysseus packed the men’s ears with wax, while he himself, ever curious, kept his ears open but had himself tied to the mast to keep from flinging himself into the water or steering his ship toward sure destruction in his desire to see them.A siren today is a sinister but almost irresistible woman.A siren song, however, may be any appeal that lures a person to act against his or her better judgment.
Why have a siren on campus?
UNCW has seen the need for an instant notification system for the campus that can alert the campus community of major emergencies.A siren system serves the purpose of notifying the UNCW community who are outdoors instantly if a major emergency is occurring on campus.While fire alarms can notify building occupants to immediately evacuate a space, the siren system allows for a method of notifying students, faculty, staff, and visitors who are outdoors that a major emergency is taking place and to seek shelter to stay safe.
Is it any good?
Suspenseful and foreboding, this series is a thrilling jaunt into a far less sanitized version of mermaid lore than what’s usually presented.The scares are real, the secrets tantalizing, and the impending doom palpable as the story unfolds.Add a sidebar government conspiracy and some men-in-black types determined to keep the truth from the average population, and you get tension and anticipation in just about every scene.
What’s the story?
SIREN opens as the coastal town of Bristol Cove, Washington, hosts its annual Mermaid Days celebration, recalling the berg’s legendary past with the mythical creatures.Suddenly history becomes all too real as a mysterious newcomer named Ryn (Eline Powell) proves the legends true and stirs up trouble in the normally sleepy little town.As marine biologist Ben (Alex Roe) tries to piece together Ryn’s story, old secrets surrounding his family’s legacy and the town’s are revealed, and a battle for the ocean begins.
