Addressing Class Imbalance in Personality Recognition
Existing personality recognition models often suffer from significant class imbalance, leading to biased predictions. Traditional solutions like scaling model size or expanding datasets drastically increase computational complexity, making them impractical. This research tackles the fundamental challenge of ensuring fair and unbiased performance in AI systems designed for understanding human behavior.
Adaptive Focal Loss & Stratified Splitting
We introduce Adaptive Focal Loss with Personality-Stratified Dataset Splitting, a novel approach to simultaneously mitigate class imbalance and stabilize performance. This method incorporates a trainable hyperparameter to dynamically adjust loss weighting, reducing sensitivity and allowing models to focus on difficult samples more effectively, leading to robust and equitable personality recognition systems.
Robust Feature Engineering & Model Training
Our methodology involves comprehensive dataset processing including text normalization and tokenization (WordNet) and feature extraction using LIWC and TF-IDF. These features are then fed into a Multi-Layer Perceptron (MLP) model, optimized with our Adaptive Focal Loss for multi-dimensional personality recognition, ensuring efficient and accurate learning.
Beyond Accuracy: Balanced Evaluation
We emphasize the use of Balanced Accuracy (BA) as the primary evaluation metric, arguing against Regular Accuracy (RA) and F1-score for imbalanced datasets. BA provides a more reliable and fair assessment by independently evaluating positive and negative class performance, which is crucial for applications like human-robot interaction where both classes are equally important.

Majority Class in Kaggle 'Openness' Dimension
| Feature | Baseline (RA/F1) | Our Approach (Balanced Accuracy - BA) |
|---|---|---|
| Metric Reliability in Imbalanced Data | Can be deceptively high; overlooks minority class misclassification; F1-score doesn't rapidly decrease with negative label imbalance. | Provides comprehensive, fair assessment; equally weighs positive/negative class performance; crucial for human-robot interaction feedback. |
| Bias Towards Majority Class | Prone to bias; model performance overstates accuracy when majority class dominates. | Mitigates bias by independently calculating accuracy for each class, then averaging. |
Real-World Impact: Enhancing Personality-Aware Robotics
Our research has profound implications for human-robot interaction. Imagine home-care robots that truly understand user personality, adapting their communication style, providing emotional support, or encouraging physical activity based on user personality. With improved balanced accuracy and minimal computational overhead, our Adaptive Focal Loss enables these robots to offer more personalized, user-centered experiences. This leads to increased trust and adoption of robotic systems, while also assisting in the early detection of psychological disorders by recognizing behavioral pattern changes. This efficiency is critical for deploying advanced AI in resource-constrained robotic platforms.
