IncDSI: Incrementally Updatable Document Retrieval

1 code implementation19 Jul 2023 Varsha Kishore, Chao Wan, Justin Lovelace, Yoav Artzi, Kilian Q. Weinberger

Differentiable Search Index is a recently proposed paradigm for document retrieval, that encodes information about a corpus of documents within the parameters of a neural network and directly maps queries to corresponding documents.

Latent Diffusion for Language Generation

1 code implementation NeurIPS 2023 Justin Lovelace, Varsha Kishore, Chao Wan, Eliot Shekhtman, Kilian Q. Weinberger

We then demonstrate that continuous diffusion models can be learned in the latent space of the language autoencoder, enabling us to sample continuous latent representations that can be decoded into natural language with the pretrained decoder.

Fixed Neural Network Steganography: Train the images, not the network

1 code implementation ICLR 2022 Varsha Kishore, Xiangyu Chen, Yan Wang, Boyi Li, Kilian Q Weinberger

Recent attempts at image steganography make use of advances in deep learning to train an encoder-decoder network pair to hide and retrieve secret messages in images.
