December 19, 2025 • Have you ever heard a fox scream at night and thought it was a human? And why, when goats bleat, do they sometimes sound like human babies? Animals can sometimes make similar ...

In January 1993, a gunman murdered seven people in a fast-food restaurant in Palatine, a suburb of Chicago. In his dual roles as an administrative executive and spokesperson for the police department, ...

Abstract: In this paper, we propose three modular multiplication algorithms that use only the IEEE 754 binary floating-point operations. Several previous studies have used floating-point operations to ...

Fun ways to work and play with new machine learning tools What, exactly, is machine learning? How can you implement it, and which tools will you need? This book shows you how to build predictive ...

This is a logic simulator to verify the theoretical results (latency & area) of MultPIM. This logic simulator models a memristive crossbar row with partitions, and then simulates running the MultPIM ...

Abstract: Generalized sparse matrix-matrix multiplication (SpGEMM) is a key primitive kernel for many high-performance graph algorithms as well as for machine learning and data analysis algorithms.
