Re-embedding words
We present a fast method for re-purposing existing semantic word vectors to improve performance in a supervised task. Recently, with an increase in computing resources, it became possible to learn rich word embeddings from massive amounts of unlabeled data. However, some methods take days or weeks to learn good embeddings, and some are notoriously difficult to train. We propose a method that ta...
متن کاملFox re-embedding and Bing submanifolds
In 1948, Fox showed that every 3-submanifold of the 3-sphere can be re-embedded so that the closure of the complement is a union of handlebodies. In 1958, Bing showed that a closed 3-manifold is the 3-sphere if and only if every knot in the manifold can be isotoped to lie within an embedded 3-ball in the manifold. In this talk, we will discuss a common generalization of these two classical theo...
متن کاملDeep Person Re-Identification with Improved Embedding
Person re-identification task has been greatly boosted by deep convolutional neural networks (CNNs) in recent years. The core of which is to enlarge the inter-class distinction as well as reduce the intra-class variance. However, to achieve this, existing deep models prefer to adopt image pairs or triplets to form verification loss, which is inefficient and unstable since the number of training...
متن کاملWord Re-Embedding via Manifold Dimensionality Retention
Word embeddings seek to recover a Euclidean metric space by mapping words into vectors, starting from words cooccurrences in a corpus. Word embeddings may underestimate the similarity between nearby words, and overestimate it between distant words in the Euclidean metric space. In this paper, we re-embed pre-trained word embeddings with a stage of manifold learning which retains dimensionality....
متن کاملEnhancing and Constructing Two Way Matrix Embedding For Efficient Embedding
In designing steganographic schemes, matrix embedding is an efficient method for increasing the embedding efficiency that is defined as an average number of bits embedded via per change on the cover. Matrix embedding is a previously introduced coding method that is used in steganography to improve the embedding efficiency (increase the number of bits embedded per embedding change). Higher embed...
