Symbolic AI or Good Old-Fashioned AI was the dominant paradigm in AI research from 1950s to 1980s and based on intelligence attained through manipulation of symbols and logic.
The Sub-symbolic AI approach relies on statistical and numerical methods that learn patterns from the data.
The Connectionist approach excels in pattern recognition and classification tasks and involves neural network-based Artificial Intelligence.
In Logical Approach, reasoning is done based on formal logic systems and results are meaningful and verifiable.
Biologically Inspired AI, based on mimicking structures and processes of biological systems, focuses on creating general intelligence.
The Engineering-Focused Design mainly focuses on solving specific tasks efficiently using domain-specific knowledge and heuristics.
There is a continuing debate on approaches to Artificial Intelligence between logical reasoning and deep learning, scruffy versus neat approaches.
Understandably, to make truly intelligent machines, a hybrid approach will be necessary for Artificial Intelligence researchers.
AI is still evolving, and it is crucial for policymakers, ethicists, researchers, and the public to understand the different approaches and methods being used.
This detailed understanding will influence the impact of AI systems on society and make a difference in the innovative and exciting progress of ensuring the future of AI research.
