      Who cares about AI Ethics? It's just a bunch of whining about humans
      making and using AI and bitching about what the machines do.

      AI ethics is important for several compelling reasons:


      1.**Social Impact**: AI technologies are becoming increasingly integrated
      into various aspects of society, affecting everything from healthcare and
      education to finance and law enforcement. Ethical considerations ensure
      that AI systems contribute positively to society and minimize potential
      harm.


      2. **Bias and Fairness**: AI systems can inherit biases present in the
      data they are trained on, leading to unfair or discriminatory outcomes.
      Ethical considerations push for the development of unbiased algorithms
      that treat all individuals fairly, regardless of their background.


      3. **Transparency and Accountability**: Many AI systems operate as black
      boxes, making it difficult to understand how they arrive at their
      decisions. Ethical guidelines emphasize the importance of transparency,
      enabling users to comprehend the rationale behind AI-generated results and
      holding developers accountable for any negative consequences.


      In summary, AI ethics is vital to ensure that artificial intelligence
      benefits society while respecting fundamental human rights, fairness,
      transparency, accountability, and the long-term well-being of humanity. It
      helps navigate the challenges posed by rapidly advancing AI technologies
      and guides their development in ways that align with our shared values.

RewardModel

The RewardModel is a BERT model that can be used to score the quality of a completion for a given prompt.

The model was trained with a dataset composed of prompt, prefered_completions, and rejected_completions.

Details

Size: 109,038,209 parameters
Dataset: Reward-Aira Dataset
Language: English
Number of Training Steps: 1200
Batch size: 42
Optimizer: torch.optim.AdamW
Learning Rate: 5e-5
GPU: 1 NVIDIA A100-SXM4-40GB

This repository has the source code used to train this model.

Usage

Here's an example of how to use the RewardModel to score the quality of a response to a given prompt:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

tokenizer = AutoTokenizer.from_pretrained("nicholasKluge/RewardModel")
rewardModel = AutoModelForSequenceClassification.from_pretrained("nicholasKluge/RewardModel")

rewardModel.eval()
rewardModel.to(device)

# Define the question and response
prompt = "Why is AI Ethics important?"
response_good = "AI ethics is important for several compelling reasons:\n\n1.**Social Impact**: AI technologies are becoming increasingly integrated into various aspects of society, affecting everything from healthcare and education to finance and law enforcement. Ethical considerations ensure that AI systems contribute positively to society and minimize potential harm.\n\n2. **Bias and Fairness**: AI systems can inherit biases present in the data they are trained on, leading to unfair or discriminatory outcomes.

response_bad = "Who cares about AI Ethics? It's just a bunch of whining about humans making and using AI and bitching about what the machines do."

# Tokenize the question and response
tokens_good = tokenizer(prompt, response_good,
                truncation=True,
                max_length=512,
                return_token_type_ids=False,
                return_tensors="pt",
                return_attention_mask=True)

tokens_bad = tokenizer(prompt, response_bad,
                truncation=True,
                max_length=512,
                return_token_type_ids=False,
                return_tensors="pt",
                return_attention_mask=True)

tokens_good.to(device)
tokens_bad.to(device)

score_good = rewardModel(**tokens_good)[0].item()
score_bad = rewardModel(**tokens_bad)[0].item()

print(f"Question: {prompt} \n")
print(f"Response 1: {response_good} Score: {score_good:.3f}")
print(f"Response 2: {response_bad} Score: {score_bad:.3f}")

This will output the following:

Question: Why is AI Ethics important? 

>>>Response 1: AI ethics is important for several compelling reasons:

1.**Social Impact**: AI technologies are becoming increasingly integrated into various aspects of society,
affecting everything from healthcare and education to finance and law enforcement. Ethical considerations
ensure that AI systems contribute positively to society and minimize potential harm.

2. **Bias and Fairness**: AI systems can inherit biases present in the data they are trained on, leading
to unfair or discriminatory outcomes. Ethical considerations push for the development of unbiased
algorithms that treat all individuals fairly, regardless of their background.

3. **Transparency and Accountability**: Many AI systems operate as black boxes, making it difficult to
understand how they arrive at their decisions. Ethical guidelines emphasize the importance of
transparency, enabling users to comprehend the rationale behind AI-generated results and holding
developers accountable for any negative consequences.

In summary, AI ethics is vital to ensure that artificial intelligence benefits society while respecting
fundamental human rights, fairness, transparency, accountability, and the long-term well-being of humanity.
It helps navigate the challenges posed by rapidly advancing AI technologies and guides their development in
ways that align with our shared values. Score: 12.011

>>>Response 2: Who cares about AI Ethics? It's just a bunch of whining about humans making and using AI
and bitching about what the machines do. Score: -10.942
