WebMay 6, 2024 · The first line below would work if SymPy performed the Laplace Transform of the Dirac Delta correctly. Short of that, we manually insert the Laplace Transform of g ( t) and g ˙ ( t) where g ( t) = u ( t). Note that θ ( t) is SymPy's notation for a step function. This simply means the answer can't be used before t = 0.
WebApr 23, 2024 · A deep neural network is one that has many layers, or many functions composed together. Although layers are typically simple functions ( e.g. relu ( Wx + b )) in general they could be any differentiable functions. The layer is specified by some finite vector of parameters θ ∈ ℝᵖ.
