Observational Learning

Observational Learning

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning because...

Agricultural Science
Animal Behavior
Bioacoustics

Background:

Honeybees are vital pollinators for agriculture, with queen health crucial for colony survival.
Acoustic monitoring offers a non-invasive method for observing honeybee colonies, but faces challenges in cross-apiary generalization and detecting rare queen loss events.

Purpose of the Study:

To develop and evaluate a robust acoustic monitoring system for detecting honeybee queen status across different apiaries.
To improve the generalizability of acoustic monitoring models by addressing domain gaps between apiaries.

Main Methods:

Employed noise-augmented data diversification to enhance sample variety.
Optimized lightweight convolutional neural network (CNN) architectures through ablation studies.
Utilized transfer learning with fine-tuning to adapt models to new apiary environments.

Main Results:

Achieved high accuracy (92.79%) and effective detection of queen loss (negative-class F1-score of 0.7900) in cross-apiary evaluations with limited data.
Further improved performance with full target-domain data, reaching 95.05% accuracy and an 0.8733 negative-class recall.
t-SNE and Grad-CAM visualizations confirmed effective feature transfer and expanded sample diversity.

Conclusions:

The proposed strategies enable practical, acoustic-based monitoring of honeybee queen status across diverse apiaries with minimal local data.
This approach supports long-term colony observation and management, contributing to agricultural sustainability.
