Headline: AppleReinvents Attention: Sigmoid Attention Matches Softmax Performance with Faster Inference
Lead: Apple researchers have re-examined Sigmoid attention and demonstrated its theoreticaland practical advantages over Softmax attention in Transformer models. Their findings show that Sigmoid attention, when properly normalized, achieves comparable performance to Softmax attention across various domains and scales, while offering significant speed improvements.
Key Points:
Theoretical Advantages: The research proves that Transformers with Sigmoid attention are universal function approximators, similar to Softmax attention. Additionally, Sigmoid attention benefits from improved regularization due to its lower Lipschitz constant compared to Softmax attention.
Practical Advantages: Apple has developed a hardware-aware and memory-efficient implementation of Sigmoid attention called FLASHSIGMOID, which achieves a 17% speedup over FLASHATTENTION2 on H100 GPUs.
* Performance: Experiments across various domains, including image classification, self-supervisedimage representation learning, automatic speech recognition (ASR), and language modeling, demonstrate that Sigmoid attention achieves performance comparable to Softmax attention while providing training and inference acceleration.
* Implementation: The research provides practical guidelines for implementing Sigmoid attention, including the importance of proper normalization and initialization.
