by Mandy Guo, Joshua Ainslie, David Uthus, Santiago Ontanon, Jianmo Ni, Yun-Hsuan Sung and Yinfei Yang. It’s an
encoder-decoder transformer pre-trained in a text-to-text denoising generative setting. LongT5 model is an extension of
T5 model, and it enables using one of the two different efficient attention mechanisms - (1) Local attention, or (2)
Transient-Global attention.`,ye,U,Ce="The abstract from the paper is the following:",O,N,he=`<em>Recent work has shown that either (1) increasing the input length or (2) increasing model size can improve the
performance of Transformer-based neural models. In this paper, we present a new model, called LongT5, with which we
explore the effects of scaling both the input length and model size at the same time. Specifically, we integrated
attention ideas from long-input transformers (ETC), and adopted pre-training strategies from summarization pre-training
(PEGASUS) into the scalable T5 architecture. The result is a new attention mechanism we call {\\em Transient Global}
(TGlobal), which mimics ETC’s local/global attention mechanism, but without requiring additional side-inputs. We are
able to achieve state-of-the-art results on several summarization tasks and outperform the original T5 models on
question answering tasks.</em>`,K,L,X=`This model was contributed by <a href="https://huggingface.co/stancld" rel="nofollow">stancld</a>.

input sequence exceeds commonly used 512 tokens. It is capable of handling input sequences of a length up to 16,384 tokens.</li> <li>For <em>Local Attention</em>, the sparse sliding-window local attention operation allows a given token to attend only <code>r</code>
tokens to the left and right of it (with <code>r=127</code> by default). <em>Local Attention</em> does not introduce any new parameters
to the model. The complexity of the mechanism is linear in input sequence length <code>l</code>: <code>O(l*r)</code>.</li> <li><em>Transient Global Attention</em> is an extension of the <em>Local Attention</em>. It, furthermore, allows each input token to
interact with all other tokens in the layer. This is achieved via splitting an input sequence into blocks of a fixed
length <code>k</code> (with a default <code>k=16</code>). Then, a global token for such a block is obtained via summing and normalizing the embeddings of every token
in the block. Thanks to this, the attention allows each token to attend to both nearby tokens like in Local attention, and
also every global token like in the case of standard global attention (<em>transient</em> represents the fact the global tokens
are constructed dynamically within each attention operation).  As a consequence, <em>TGlobal</em> attention introduces
a few new parameters — global relative position biases and a layer normalization for global token’s embedding.
