Parameter optimization of support vector machine based on improved cuckoo search algorithm

Xi'an Gongcheng Daxue xuebao, 2022
To solve the problem of difficult selection of penalty factor and kernel function parameters of Support Vector Machine (SVM), an improved cuckoo search algorithm (GFCS) was proposed to optimize SVM parameter model (GFCS-SVM) . The GFCS algorithm improves

Ancient origin and maternal inheritance of blue cuckoo eggs [PDF]

, 2016
Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or 'gentes') in avian brood parasites.

Climate change is associated with asynchrony in arrival between two sympatric cuckoos and both host arrival and prey emergence

Royal Society Open Science
Matching the timing of spring arrival to the breeding grounds with hosts and prey is crucial for migratory brood parasites such as cuckoos. Previous studies have focused mostly on phenological mismatch between a single cuckoo species and its hosts but ...
