A new Suggested Conjugate Gradient Algorithm with Logistic Mapping

Science Journal of University of Zakho, 2016
In this paper, we will use logistic mapping to find new conjugate gradient coefficients for unconstrained optimization.

Next‐generation sequencing sheds new light on a major lineage of Acanthaceae, clarifying previously uncertain relationships in Barlerieae

TAXON, EarlyView.
Abstract The Acanthaceae tribe Barlerieae is an understudied lineage that consists of ca. 500 species, many of which are rare and range restricted. Though understudied, it is clear that many species play vital roles in tropical ecosystems, including supporting a wide range of pollinators and herbivores. The tribe contains 13 genera, the two largest and

Image Noise Reduction and Solution of Unconstrained Minimization Problems via New Conjugate Gradient Methods

Mathematics
The conjugate gradient (CG) directions are among the important components of the CG algorithms. These directions have proven their effectiveness in many applications—more specifically, in image processing due to their low memory requirements.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Local Search and the Evolution of World Models

Topics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...
