Expand description

Configuration for a SpikeNetFixed network.

All Q1.14 parameters should be in the range [-2.0, +2.0) when converted from f64 via f64_to_q14(). Typical defaults:

Parameter	f64	Q1.14
alpha	0.95	15565
kappa	0.99	16220
kappa_out	0.90	14746
eta	0.001	16
v_thr	0.50	8192
gamma	0.30	4915
spike_threshold	0.05	819

Fields§

§n_input: usize

Number of raw input features (encoded to 2x for spike channels).

§n_hidden: usize

Number of hidden LIF neurons.

§n_output: usize

Number of output readout neurons.

§alpha: i16

Membrane decay factor in Q1.14.

§kappa: i16

Eligibility trace decay factor in Q1.14.

§kappa_out: i16

Readout membrane decay factor in Q1.14.

§eta: i16

Learning rate in Q1.14.

§v_thr: i16

Firing threshold in Q1.14.

§gamma: i16

Surrogate gradient dampening factor in Q1.14.

§spike_threshold: i16

Delta encoding threshold in Q1.14.

§seed: u64

PRNG seed for reproducible weight initialization.

§weight_init_range: i16

Weight initialization range: weights sampled from [-range, +range] in Q1.14.

§use_astrocyte: bool

Enable astrocyte-gated modulation of input weights.

§astrocyte_tau: f64

Astrocyte EWMA time constant (higher = slower adaptation). Default: 1000.

§astrocyte_mode: AstrocyteMode

Astrocyte gating mode (only used when use_astrocyte is true).

WeightMod (default): scales forward-pass input weights. LearningRateGate: scales the per-neuron learning rate during updates (Dong & He 2025, Frontiers Neurosci, Eq. 4 – AGMP proper).
