description Retentive Network Overview
Retentive Network (RetNet) is a large language model architecture introduced by Microsoft researchers in 2023. It proposes a retention mechanism as a substitute for the self-attention mechanism used in standard Transformer models. This architectural shift is designed to allow parallel computation during training and recurrent computation during inference, achieving high efficiency. The structure aims to resolve the high memory cost associated with processing long text sequences in natural language processing tasks.
help Retentive Network FAQ
What makes the Retentive Network architecture different from a Transformer?
Retentive Network (RetNet) replaces the traditional self-attention mechanism with a retention mechanism. This allows the model to train in parallel like a Transformer while performing inference recurrently to save memory.
Who proposed the Retentive Network model?
The Retentive Network was introduced by Microsoft researchers in 2023. The architecture was specifically designed to overcome the scaling limitations of standard Transformer models during inference.
Does the Retentive Network allow for parallel training?
Yes, the RetNet architecture enables parallel computation during the training phase. During inference, it switches to a recurrent mode to achieve efficient generation and reduced memory consumption.
Why do we need an alternative to the attention mechanism in large language models?
Standard self-attention mechanisms require massive memory and computational overhead during inference as context length grows. RetNet solves this by using retention, maintaining the effectiveness of attention while drastically lowering deployment costs.
