From: Intelligent systems for sitting posture monitoring and anomaly detection: an overview

Techniques

Advantages

Limitations

Refs.

Rule-based

Application simplicity

High inference speed

Low computational cost

Transparent and explainable process

Expert knowledge required

Difficulty in capturing complex relationships

Limited to a low number of postures and differentiated from each other

[49, 63, 65, 74]

Statistical

Interpretability of results

They provide probability estimations for each class

Reasonable training time

Assumption that the data follow a probability distribution

Expert knowledge required

Sensitive to irrelevant features

Limited performance with complex data

[13,14,15,16,17,18,19,20,21,22,23, 28]

Intelligent

Ability to capture complex relationships

Greater accuracy

Adaptable to input changes

Ability to ignore redundant features

Need for large data sets

Increased training time and computational resources

Difficulty in selecting hyperparameters

Lack of interpretability of the decision making process
