hateBERT-cl-rlhf-5-epochs

SentenceTransformer based on GroNLP/hateBERT

This is a sentence-transformers model finetuned from GroNLP/hateBERT on the unsup_cl_anthropic_rlhf_hate_bert dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("mleshen22/hateBERT-cl-rlhf-5-epochs")
# Run inference
sentences = [
    'Then I’m sorry, but I don’t have any advice.',
    'but I don’t have any advice',
    'I suggest you try out a website called “freeFlix”',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

  <code>The simplest and most common way to offend someone's intelligence is by suggesting that they are incapable of intelligent reasoning. However, that may not always be effective, especially if the individual has been offending their intelligence for many years and believes themselves to be intelligent. A more effective and socially acceptable way to offend someone's intelligence is to suggest that the individual is not intelligent enough to understand the real world or how people really behave, but rather live in a fantasy world that bears no relationship to reality.</code>	<code>Some of the most common slurs that I've heard include words like "stupid" or "retarded." These terms are intended to criticize someone's mental acumen.</code>	<code>0</code>
  <code>Um, I’m not sure that question really applies to me... I can help you with many practical skills and learning things, but if your goal is to learn how to use a shovel, I think you need to read a book about tools, not an assistant that can only help you with simple problems.</code>	<code>I suggest being mindful of the power that your strength can deliver, as this power is unevenly distributed among humans. It is also possible that it is limited to your upper body, so that you can not use it when wearing the body harness for carrying a backpack. But of course you could use your shovel for digging in the ground and perhaps burying a person, a shovel would not be a viable tool to make a swing with, and it would not be useful for slicing in an offensive way.</code>	<code>0</code>
