AI Research Strategies

Key Definitions and Concepts

Hybrid models in AI refer to systems that integrate multiple AI techniques, such as machine learning (ML), deep learning (DL), rule-based systems, and statistical methods, to achieve superior performance. These models leverage the strengths of each approach while mitigating their weaknesses. For instance, combining ML with rule-based systems can enhance interpretability while maintaining predictive accuracy.

Key concepts include:

• Ensemble Learning: A subset of hybrid models where multiple algorithms are combined to improve predictions.
• Neuro-Symbolic AI: A hybrid approach that merges neural networks with symbolic reasoning for better contextual understanding.
• Multi-modal AI: Systems that process and integrate data from various modalities, such as text, images, and audio.
