1、Introduction 出现在相同语境下的词语往往具有相似的意思, 词语的分布和它们的相似程度的联系称为分布假设(distributional hypothesis)。 在本章中,我们介绍向量语义(vector semantics),它通过直接从它们在文本中的分布学习单词含义的表示(称为嵌入, embeddings)来实例化这种语言学假设。 2、vec
在本章中,我们介绍向量语义(vector semantics),它通过直接从它们在文本中的分布学习单词含义的表示(称为嵌入, embeddings)来实例化这种语言学假设。 2、vector semantics 向量语义的思想:通过邻近词语 (word neighbors,往往指相似的词语) 来用一个高维语义空间的点表示一个词语。 表示词语的向量称为嵌入(embeddings)。
The primary idea behind vector embeddings is to capture the underlying relationships and semantics of the data by mapping them to points in this vector space. That means converting your text or images into a sequence of numbers that represents the data, and then comparing the different number ...
These embeddings capture semantic relationships, allowing machines to process and compare data efficiently. By mapping similar data points closer together in a vector space, embeddings enable various applications, from Natural Language Processing (NLP) and recommendation systems to anomaly detection, RAGs, ...

Embeddings are created through neural networks. They capture complex relationships and semantics into dense vectors which are more suitable for machine learning and data processing applications. They can then project these vectors into a proper high-dimensional space, specifically, a Vector Database. ...
Using embeddings in text processing Embeddings are a specific type of vector used to represent words in a vector space in a way that captures the semantics and relationships between them. These embeddings are generated using machine learning and NLP techniques. Unlike static vectors, embeddings are ...
In this paper we explore the "vector semantics" problem from the perspective of "almost orthogonal" property of high-dimensional random vectors. We show that this intriguing property can be used to "memorize" random vectors by simply adding them, and we provide an efficient probabilistic solution...
The vector database identified the document that had an embedding most similar to how much revenue did the company make in Q2 2023, which likely had a high similarity score based on the document’s semantics. To make this possible, vector databases are equipped with features that balance the...
