Avoidance learning [PDF]

open access: yes, 2015
Humans are evolutionary wired to avoid potentially dangerous situations. Such ability allows us to cope with threatening circumstances, ranging from the encounter of animal predators to speeding cars on the highway. Adaptive as it seems in those situations, individuals may sometimes excessively avoid cues or situations even when a threatening outcome ...

Automatic collision avoidance of ships [PDF]

open access: yes, 2008
One of the key elements in automatic simulation of ship manoeuvring in confined waterways is route finding and collision avoidance. This paper presents a new practical method of automatic trajectory planning and collision avoidance based on an artificial

The Machine Learning Method of PIDVCA [PDF]

open access: yesTransNav, 2020
Building a dynamic collision knowledge base of self-learning is one of the core contents of implementing "personified intelligence" in Personifying Intelligent Decision-making for Vessel Collision Avoidance (short for PIDVCA).

Online Learning for Obstacle Avoidance

open access: yesCoRR, 2023
We approach the fundamental problem of obstacle avoidance for robotic systems via the lens of online learning. In contrast to prior work that either assumes worst-case realizations of uncertainty in the environment or a stationary stochastic model of uncertainty, we propose a method that is efficient to implement and provably grants instance-optimality

Metabolic and behavioural effects of hermit crab shell removal techniques: Is heating less invasive than cracking?

open access: yesAnimal Welfare, 2023
Hermit crabs (Paguroidea; Latreille 1802) offer great opportunities to study animal behaviour and physiology. However, the animals’ size and sex cannot be determined when they are inside their shell; information crucial to many experimental designs. Here,

The Effects of Intravermis Cerebellar Microinjections of Dopaminergic Agents in Motor Learning and Aversive Memory Acquisition in Mice

open access: yesFrontiers in Behavioral Neuroscience, 2021
The cerebellum receives dopaminergic innervation and expresses the five types of described dopaminergic receptors. The cerebellar function involves both motor movement and cognition, but the role of cerebellar dopaminergic system on these processes ...

Imaging of Functional Brain Circuits during Acquisition and Memory Retrieval in an Aversive Feedback Learning Task: Single Photon Emission Computed Tomography of Regional Cerebral Blood Flow in Freely Behaving Rats

open access: yesBrain Sciences, 2021
Active avoidance learning is a complex form of aversive feedback learning that in humans and other animals is essential for actively coping with unpleasant, aversive, or dangerous situations.

The Effect of Virtual Fencing Stimuli on Stress Responses and Behavior in Sheep

open access: yesAnimals, 2019
To understand the animal welfare impact of virtual fencing stimuli (audio cue ‘beep’ and electrical stimulus) on naïve sheep, it is necessary to assess stress responses during the animal’s first encounters with these stimuli ...
