NeuroPulse.jl (TemporalFocus)

Generated with Grok Build: Grok 4.5 · xAI Imagine (/imagine)

Spike-driven relevance routing for modular neural systems.

Julia package: TemporalFocus 0.1.0 | Julia: 1.9+ (CI: 1.12) | License: MIT OR Apache-2.0

The GitHub repository and Pages path remain Limen-Neural/NeuroPulse.jl. The package identity in Project.toml is TemporalFocus. Use using TemporalFocus in new code.

TemporalFocus computes per-tick routing weights from:

• spike density (α = 0.50)
• manifold surprise via EMA readout deviation (β = 0.35)
• routing momentum (γ = 0.15)

It is intentionally narrow: relevance routing only — not an SNN runtime, trainer, or hardware supervisor.

Public API (preferred)

Symbol	Role
ActivityRegion	Per-region summary: rate ∈ [0,1] + readout Vector{Float32}
RegionRouter	Pre-allocated mutable routing state
update_routing!	In-place per-tick weight update
routing_diagnostics	One-line log string
adapt_leak!	Optional stress → leak helper
save_state / load_state!	Checkpoint / restore router buffers

Legacy aliases (LobeState, NeroOrchestrator, update_relevance!, nero_diagnostics) still resolve to the generic API.

Quick Start

using TemporalFocus

router = RegionRouter(
    n_regions = 4,
    n_out = 8,
    region_names = ["sensor", "reservoir", "memory", "decoder"],
)

regions = [
    ActivityRegion(0.82f0, Float32[0.9, 0.7, 0.2, 0.1, 0.0, 0.1, 0.3, 0.5]),
    ActivityRegion(0.28f0, Float32[0.3, 0.2, 0.1, 0.0, 0.0, 0.0, 0.2, 0.2]),
    ActivityRegion(0.41f0, Float32[0.4, 0.6, 0.5, 0.2, 0.1, 0.1, 0.0, 0.1]),
    ActivityRegion(0.12f0, Float32[0.1, 0.1, 0.0, 0.0, 0.4, 0.6, 0.8, 0.9]),
]

update_routing!(router, regions)
println(router.routing_weights)
println(routing_diagnostics(router))
