Hybrid search: Enhancing search efficiency through the combination of different techniques.
Hybrid search is an approach that combines multiple search techniques to improve the efficiency and effectiveness of search algorithms, particularly in complex and high-dimensional spaces. By integrating various methods, hybrid search can overcome the limitations of individual techniques and adapt to diverse data distributions and problem domains.
In the context of machine learning, hybrid search has been applied to various tasks, such as path planning for autonomous vehicles, systematic literature reviews, and model quantization for deep neural networks. These applications demonstrate the potential of hybrid search in addressing complex problems and enhancing the performance of machine learning algorithms.
One example of hybrid search in machine learning is the Roadmap Hybrid A* and Waypoints Hybrid A* algorithms for path planning in industrial environments with narrow corridors. These algorithms combine Hybrid A* with graph search and topological maps, respectively, to improve computational speed, robustness, and flexibility in navigating obstacles and generating optimal paths for car-like autonomous vehicles.
Another application is the use of hybrid search strategies for systematic literature reviews in software engineering. By combining database searches in digital libraries with snowballing techniques, researchers can achieve a balance between result quality and review effort, leading to more accurate and comprehensive reviews.
In the field of deep neural network compression, hybrid search has been employed to automatically realize low-bit hybrid quantization of neural networks through meta learning. By using a genetic algorithm to search for the best hybrid quantization policy, researchers can achieve better performance and compression efficiency compared to uniform bitwidth quantization.
A company case study that demonstrates the practical application of hybrid search is the development of Hybrid LSH, a technique for faster near neighbors reporting in high-dimensional space. By integrating an auxiliary data structure into LSH hash tables, the hybrid search strategy can efficiently estimate the computational cost of LSH-based search for a given query, allowing for better performance across a wide range of search radii and data distributions.
In conclusion, hybrid search offers a promising approach to enhance the efficiency and effectiveness of search algorithms in machine learning and other domains. By combining different techniques and adapting to diverse problem contexts, hybrid search can lead to improved performance and more accurate results, ultimately benefiting a wide range of applications and industries.
