Decision Making: Traditional Method

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Decision Making

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

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...

Decision Making: P-value Method

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...

Evolutionary Psychology

Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...

Background:

Rule-based systems are crucial for interpretable AI.
Learning optimal rule sets in continuous and discrete domains remains challenging.
Existing methods may produce large, redundant rule sets.

Purpose of the Study:

To present a novel evolutionary algorithm, hierarchical decision rules (HIDER), for efficient rule learning.
To develop an approach that generates a hierarchical structure of rules, enabling rule set reduction.
To evaluate HIDER's performance against established algorithms on real-world datasets.

Main Methods:

Utilizing evolutionary algorithms with both real and binary coding for population individuals.
Implementing a hierarchical rule generation process where rules are sequentially evaluated.
Testing the HIDER system on diverse datasets from the UCI repository.

Main Results:

HIDER successfully generated hierarchical rule sets, reducing the overall number of rules.
Comparative analysis using ten-fold cross-validation showed competitive or superior performance against C4.5, C4.5Rules, See5, and See5Rules.
Experimental results indicate HIDER's practical effectiveness on real data.

Conclusions:

HIDER offers an effective approach for learning hierarchical rules in machine learning.
The algorithm's ability to reduce rule complexity and its strong performance make it a valuable tool.
HIDER demonstrates practical applicability and potential for further development in rule-based systems.
