چکیده
Energy landscapes provide a conceptual framework for structure prediction, and detailed understanding of their topological features is necessary to develop efficient methods exploration. The ability visualise these surfaces essential, but the high dimensionality corresponding configuration spaces makes this difficult. Here we present Stochastic Hyperspace Embedding Projection (SHEAP), method energy landscape visualisation inspired by state-of-the-art algorithms reduction through manifold learning, such as t-SNE UMAP. performance SHEAP demonstrated its application Lennard-Jones clusters, solid-state carbon, quaternary system C+H+N+O. It produces meaningful interpretable low-dimensional representations landscapes, reproducing well known funnels, providing fresh insight into layouts. In particular, an intrinsic low in distribution local minima across space revealed.

Visualizing energy landscapes with metric disconnectivity graphs
The visualization of multidimensional energy landscapes is important, providing insight into the kinetics and thermodynamics of a system, as well the range of structures a system can adopt. It is, however, highly nontrivial, with the number of dimensions required for a faithful reproduction of the landscape far higher than can be represented in two or three dimensions. Metric disconnectivity gr...

متن کاملVisual Saliency Estimation through Manifold Learning
Most early work makes more effort to build saliency models on low-level image features based on local contrast. These methods investigate the rarity of image regions with respect to (small) local neighborhoods. Recent efforts have been made toward global contrast based saliency estimation, where saliency of an image region is evaluated at the global scale with respect to the entire image. ...
متن کاملUnraveling Flow Patterns through Nonlinear Manifold Learning
From climatology to biofluidics, the characterization of complex flows relies on computationally expensive kinematic and kinetic measurements. In addition, such big data are difficult to handle in real time, thereby hampering advancements in the area of flow control and distributed sensing. Here, we propose a novel framework for unsupervised characterization of flow patterns through nonlinear m...
متن کاملVisualizing curvature on the Lorenz manifold
The Lorenz manifold is an intriguing two-dimensional surface that illustrates chaotic dynamics in the well-known Lorenz system. While it is not possible to find the Lorenz manifold as an explicit analytic solution, we have developed a method for calculating a numerical approximation that builds the surface up as successive geodesic level sets. The resulting mesh approximation can be read as cro...
