- MSC (Master of Science, 理学硕士) | ||
理学硕士是一种研究生学位,授予完成了科学或技术领域深入学习和研究的学生。在某些领域,它也可能与工程或其他专业相关联。 | ||
- Word2Vec | ||
Word2Vec 是一种用于学习词嵌入的计算模型,旨在将单词转换为向量形式,使得这些向量能够捕捉单词之间的语义和语法关系。Word2Vec 模型通过训练神经网络学习单词的表示,有两种主要的训练架构:CBOW(Continuous Bag of Words)和Skip-gram。 | ||
- CBOW (Continuous Bag of Words, 连续词袋模型) | ||
CBOW 是Word2Vec的一种训练模式,它预测当前单词基于其上下文。具体来说,模型试图根据上下文中的单词来预测目标单词,这有助于捕捉单词之间的关系和上下文信息。 | ||
- Bio/Named Entity Recognition (生物命名实体识别/命名实体识别) | ||
命名实体识别(NER)是自然语言处理中的一个任务,旨在从文本中识别具有特定意义的实体,如人名、地名、机构名等。在生物医药领域,命名实体识别可能特别指向生物实体的识别,如基因、蛋白质等的名称。 | ||
