你可以把这种模块化看作乐高积木：处理流程的每个部分都可以完全被另一个类似的算法
替换。通过这种模块化的方式，新发布的模型可以被整合到其架构中。随着语言人工智能
领域的发展，
BERTopic
也在不断成长！
BERTopic
的模块化特性
BERTopic
的模块化设计还有另一个优势：它可以在使用同一个基础模型的前提下，根
据不同的使用场景灵活调整。例如，
BERTopic
支持多种算法变体：
•
引导式主题建模
•
（半）监督主题建模
•
层次化主题建模
•
动态主题建模
•
多模态主题建模
•
多视角主题建模
•
在线和增量主题建模
•
零样本主题建模
•
……
模块化和算法的灵活性是作者将
BERTopic
打造成主题建模一站式解决方案的基础。
你可以在
BERTopic
的官方文档或
GitHub
仓库中找到其完整功能概述。
要在我们的
ArXiv
数据集上运行
BERTopic
，可以使用之前定义的模型和嵌入向量（虽然
这不是必需的）：
from bertopic import BERTopic
# 使用之前定义的模型训练我们的模型
topic_model = BERTopic
(
embedding_model=embedding_model
,
umap_model=umap_model
,
hdbscan_model=hdbscan_model
,
verbose=True
)
.fit
