  Confusion 1) what is difference between Topic Modelling and Clustering? 2) How CountVectorizor work for tokenization and stop word removal after embedding? is work in numeric data?

  Does LLaMA have built-in mechanisms for ensuring data security during inference or training? Are there any recommended approaches for fine-tuning or querying the model on confidential datasets without risking data leakage? Can LLaMA be deployed in a completely offline environment for increased security?

  I have a lot of outliers in my project, I want to get the probability of each sentence belonging to each topic, If I use topics,probs= topic_model.fit_transform(sentences,embeddings=embeddings) the probs obtained by this method will contain every sentence (including outliers). Is there any way to extract these outliers, and do these outliers also have topic probability proportions

  I set my own umap (with random_state=0), hdbscan (with random_state=0), ctfidf_model, and representation_model, and then passed these four modules into the BERTopic() function. However, my results are different every time I run the code. What should I do?
