Theorem 2. (Progress) If ∅ ⊢db e : τ and e is not a value and not bp-stuck, then e −→ e′ for some term e′. 3.1. Static Types for Implicit Values Figure 3 defines more precise type rules for λdb that track the use of dynamic bindings by annotating every function ...
Here, for a gradient-based optimization technique, the gradient E of the loss function has to be calculated. The corresponding theory is based on the implicit function theorem, see [6, 9], and [1]. An efficient numerical approximation of z in Eq. (1) is also rather complex, for ...
Extreme Value Theorem. Let f:X\rightarrow \mathbb{R} be a continuous function and X be a compact set. Then there exists x_0\in X such that f(x_0)=\sup_{x\in X} f(x) . Similarly, exists x_1\in X s.t. f(x_1)=\inf_{x\in X} f(X) .Proof: Since f is continuous ...
Additionally, nonlinearity causes [K] to become a function of displacement. As such, updating or factorizing the global stiffness matrix [K] before inverting it to [K]−1 for computing the nodal displacements needed before the next time step can be proceed is computationally intensive. For ...
6.3. Ablation We first compare our efficient second-order deriva- tive backward computation (Theorem 1) implemented in CUDA with a baseline where we automatically compute the second-order derivative in PyTorch [42] using their compu- tational graph. As show...
Theorem 1.2 Let φ:Ω×R×RN→R be a Carathéodory function and let ψ:R→R be continuous. Suppose that (i) ψ is non-constant on intervals; (ii) for all (x,z,w)∈Ω×R×RN, the function y↦φ(x,z,w)−ψ(y) changes sign; (iii) there exist a∈Lp′(Ω,R0+),...
Theorem 3.1 indicates that there exists a unique fourth-order IMSVERK method with two stages: $$\begin{aligned} \left\{ \begin{array}{l} \displaystyle Y_1=e^{-\frac{3-\sqrt{3}}{6}hM}y_0+h\big [\frac{1}{4}f(Y_1)+\frac{3-2\sqrt{3}}{12}f(Y_2)\big ],\\ \displaysty...
