The embedding theorem [Man81, Tak81, CSY91] is silent on the choice of time delay to use in constructing d-dimensional data vectors. Indeed, it allows any time delay, except certain multiples of the precise period of a periodic signal [CSY91], as long as one has an infinite amount of...
The celebrated Takens' embedding theorem provides a theoretical foundation for reconstructing the full state of a dynamical system from partial observations. However, the classical theorem assumes that the underlying system is deterministic and that observations are noise-free, limiting its applicability in...

Takens’ time delay embedding theorem is valid for time series generated by deterministic dynamical systems, but not for stochastic ones. In spite of this, we investigated the applicability of time delay embedded temporal and spatial outlier detection on stochastic signals with deterministic dynamics as...
using time-delay embedding vectors, as follows: the manifold of anmdimensional state vectorXcan be reconstructed as\(X(t)=\{x(t),x(t-\eta ),...,x(t-(m-1)\eta )\}\). Here,\(\eta\)is the embedding delay, and can be obtained using the embedding construction procedure based on ...
For the proof of Theorem 1.4, we hope to establish the sharp space–time decay rate for the micro-rotational velocity w. If we make energy estimates on (2.1)3 directly, then we will encounter the trouble termsQ1:=−4α⋅γ∫R3|x|2γ−2xj∂ixj∇ku∇kwidx, andQ2:=−2μ...
Taken's delay embedding theorem states that a pseudo state-space can be reconstructed from a time series consisting of observations of a chaotic process. However, experimental observations are inevitably corrupted by measurement noise, which can be modelled as Additive White Gaussian Noise (AWGN). Th...

In practical terms, this is accomplished using the technique of "cross mapping": a time delay embedding is constructed from the time series of y, and the ability to estimate the values of x from this embedding quantifies how much information about x has been encoded into y. Thus, the ...
Considering the theorem presented by Takens35, we postulate that it is possible to reconstruct the original time series by using time delay embedding vectors, where the delay vectors consist of scalar measurements of the system’s state. The delay vectors \({z}_{t}=[{x}_{t},{x}_{t+\...
