Plant Disease Detection Using Deep Convolutional Neural Network

open access: yesApplied Sciences, 2022
In this research, we proposed a novel 14-layered deep convolutional neural network (14-DCNN) to detect plant leaf diseases using leaf images. A new dataset was created using various open datasets.

Partitioning Search Spaces of a Randomized Search [PDF]

open access: yesFundamenta Informaticae, 2009
This paper studies the following question: given an instance of the propositional satisfiability problem, a randomized satisfiability solver, and a cluster of n computers, what is the best way to use the computers to solve the instance? Two approaches, simple distribution and search space partitioning as well as their combinations are investigated both

Generalization of navigation memory in honeybees

open access: yesFrontiers in Behavioral Neuroscience, 2023
Flying insects like the honeybee learn multiple features of the environment for efficient navigation. Here we introduce a novel paradigm in the natural habitat, and ask whether the memory of such features is generalized to novel test conditions. Foraging

Stagnation Detection with Randomized Local Search* [PDF]

open access: yesEvolutionary Computation, 2021
AbstractRecently a mechanism called stagnation detection was proposed that automatically adjusts the mutation rate of evolutionary algorithms when they encounter local optima. The so-called SD-(1+1) EA introduced by Rajabi and Witt (2022) adds stagnation detection to the classical (1+1) EA with standard bit mutation.

Diffusion–Advection Equations on a Comb: Resetting and Random Search

open access: yesMathematics, 2021
This review addresses issues of various drift–diffusion and inhomogeneous advection problems with and without resetting on comblike structures. Both a Brownian diffusion search with drift and an inhomogeneous advection search on the comb structures are ...

Random Hyperplane Search Trees

open access: yesSIAM Journal on Computing, 2009
Summary: A hyperplane search tree is a binary tree used to store a set \(S\) of \(n\) \(d\)-dimensional data points. In a random hyperplane search tree for \(S\), the root represents a hyperplane defined by \(d\) data points drawn uniformly at random from \(S\).
