A groundbreaking machine learning algorithm developed at Los Alamos National Laboratory has shattered the limitations of data processing by successfully handling massive data sets that exceed a computer’s available memory. The algorithm achieves this feat by identifying the key features of the data and dividing them into manageable batches, preventing the hardware from becoming overloaded.
During a test run on Oak Ridge National Laboratory’s Summit supercomputer, the algorithm set a new world record for factorizing extensive data sets. It proved equally efficient on laptops as well as supercomputers, presenting a highly scalable solution for overcoming hardware bottlenecks. This breakthrough has wide-ranging implications for various fields, including cancer research, satellite imagery analysis, social media networks, national security science, and earthquake research.
The Los Alamos team implemented an ‘out-of-memory’ approach to non-negative matrix factorization, enabling the algorithm to factorize larger data sets than ever before. By breaking down the data into smaller units, the algorithm optimizes the use of available resources, allowing researchers to keep up with the exponential growth of data sets.
This algorithm challenges traditional data analysis methods that require data to fit within memory constraints. Instead, it breaks the data into smaller segments to be processed one at a time. The algorithm leverages hardware features like GPUs to accelerate computation and fast interconnects to efficiently move data between computers. Multiple tasks can be done simultaneously, enhancing overall efficiency.
