Sobre este vídeo

While the best AI systems train neural networks based on 32-bit algorithms, the procedure can also be carried out with “binary neural networks” (1-bit algorithm). This drastically reduces the effort in the individual calculation steps and immediately leads to energy savings by a factor of 20. Although binary neural networks are currently about 5 % less accurate than those of AI systems of global players, the reduction can save 95 % electricity usage. With AI applications being used millions of times a day, total emissions can be decreased significantly. More information...
