Natural Language Processing (Almost) from Scratch

Journal of machine learning research, 2011
We propose a unified neural network architecture and learning algorithm that can be applied to various natural language processing tasks including part-of-speech tagging, chunking, named entity recognition, and semantic role labeling. This versatility is

SCRATCH: A Scalable Discrete Matrix Factorization Hashing Framework for Cross-Modal Retrieval

IEEE transactions on circuits and systems for video technology (Print), 2020
In this paper, we present a novel supervised cross-modal hashing framework, namely Scalable disCRete mATrix faCtorization Hashing (SCRATCH). First, it utilizes collective matrix factorization on original features together with label semantic embedding ...

To scratch or not to scratch

Science, 2017
Neuroscience![Figure][1] Mice are susceptible to contagious itching. PHOTO: MARC C. PERKINS PHOTOGRAPHY, COSTA MESA, CA Observing someone else scratching themselves can make you want to do so. This contagious itching has been observed in monkeys and humans, but what about rodents?

Magpie: Alignment Data Synthesis from Scratch by Prompting Aligned LLMs with Nothing

International Conference on Learning Representations
High-quality instruction data is critical for aligning large language models (LLMs). Although some models, such as Llama-3-Instruct, have open weights, their alignment data remain private, which hinders the democratization of AI.

Scratching the surface

Current Biology, 1991
Mice with mutations at the steel locus (Sr) and the white spotting locus ( W) are phenotypically similar. They have a macrocytic anemia, are white or have a dilution of coat color, and have impaired fertility. SZ mutations result in abnormalities in stromal functions, such that migration of melanoblasts and hematopoietic stem cells is defective and the

Cat-scratch disease osteomyelitis from a dog scratch [PDF]

The Journal of Bone and Joint Surgery. British volume, 1998
Osteomyelitis is a rare manifestation of cat-scratch disease in patients who do not have AIDS. The clinical presentation and non-specific subacute course of the disease make diagnosis difficult. We present a child with osteomyelitis of a metacarpal following a dog scratch. Bartonella henselae was found to be the aetiological agent.
