Abstract: A flexible intestinal anastomosis stent which sucks secretions on an inner wall of an intestinal tract and at a suture site into a horn-shaped channel through a through-hole. The secretion is discharged to an inside of the stent body through a liquid-inlet hole after being squeezed by intestinal tract contents, thereby reducing a risk of infection at the suture site. A lower edge of the outlet end of the stent body has a concave polygonal structure, each reflex angle at a lower edge of the concave polygonal structure being formed with one inwardly folded wrinkle structure on a side wall of the stent body, and the wrinkle structure also able to accommodate the secretions. The lower edge is stressed and deformed by the intestinal tract contents to reduce a reflex angle, so that secretions in the wrinkle structure are discharged downwardly, such that risk of complications is reduced.

Abstract: An online system trains a transformer architecture by an initialization method which allows the transformer architecture to be trained without normalization layers of learning rate warmup, resulting in significant improvements in computational efficiency for transformer architectures. Specifically, an attention block included in an encoder or a decoder of the transformer architecture generates the set of attention representations by applying a key matrix to the input key, a query matrix to the input query, a value matrix to the input value to generate an output, and applying an output matrix to the output to generate the set of attention representations. The initialization method may be performed by scaling the parameters of the value matrix and the output matrix with a factor that is inverse to a number of the set of encoders or a number of the set of decoders.

Abstract: An autoencoder model includes an encoder portion and a decoder portion. The encoder encodes an input token sequence to an input sequence representation that is decoded by the decoder to generate an output token sequence. The autoencoder model may decode multiple output tokens in parallel, such that the decoder may be applied iteratively. The decoder may receive an output estimate from a prior iteration to predict output tokens. To improve positional representation and reduce positional errors and repetitive tokens, the autoencoder may include a trained layer for combining token embeddings with positional encodings. In addition, the model may be trained with a corrective loss based on output predictions when the model receives a masked input as the output estimate.
