Description of EDA-specific dictionary atoms and initial parameters.

Tonic Atoms

ϕ₁(t) = Δ₀ + Δ · t

Δ₀ ∈ {−20, −10, 1}
Δ ∈ {−0.01, −0.009, …,
0, 0.01, 0.02, …, 0.1}

Phasic Atoms

ϕ_{2} (t) = \frac{\frac{s t - t_{0}}{e^{T} decay}}{{[1 + {(\frac{s t - t_{0}}{T_{rise}})}^{- 2}]}^{2}} u (t - t_{0})

T_rise ∈ {8, 14, 18}
T_decay ∈ {10, 15, 20}
t₀ ∈ {0, 10, 20, …, 150}

u(t) = 1, t ≥ 0 and u(t) = 0 otherwise
