Flops

Definition

FLOPS, which stands for 'floating-point operations per second,' is a measure of a computer's performance, particularly in fields that require high-speed computations like deep learning. It quantifies how many floating-point calculations a system can perform in one second and is crucial for evaluating the efficiency of algorithms and models, especially when considering model compression techniques and automated model design.
