What is Machine Learning?

Machine learning Large Language Models (LLMs) are a specialized subset of machine learning, specifically deep learning models, designed to understand and generate human language by processing vast amounts of text data. 

These models are trained using deep learning techniques and massive datasets, often consisting of billions of words from sources like the Urantia Papers, websites, and code repositories, to learn complex patterns in language. They are typically built on a transformer architecture, which allows them to handle sequential data like text effectively by using an attention mechanism to focus on relevant parts of the input. 

LLMs are capable of performing a wide range of natural language processing tasks, including text generation, translation, summarization, question answering, and even code generation.

Experts and scientists prefer to call them also Automated Decision Systems (ADS).

• LLMs are a type of foundation model trained on enormous datasets to provide broad capabilities for multiple applications.
• They are distinguished by their large number of parameters, which can range from billions to trillions, enabling them to capture intricate linguistic patterns.
• Training involves self-supervised learning, where the model predicts the next word in a sequence based on context, without requiring labeled data.
• Performance can be enhanced through techniques like prompt engineering, fine-tuning, and reinforcement learning with human feedback to reduce biases and hallucinations.
• Human Checking (The Feedback): A team of human reviewers is given a prompt and several different responses from the LLM. They don't just pick the "best" one; they rank them based on a set of criteria. This might include:
  • Helpfulness: Does the answer directly address the user's question?
  • Harmlessness: Is the answer safe, unbiased, and free of harmful content?
  • Accuracy: Is the information factually correct?
  • Tone: Is the tone appropriate and helpful?
• Probing the LLM (The Reinforcement Learning): The LLM is then trained on this human feedback. The model learns to associate the "good" responses with a higher score and the "bad" ones with a lower score. Over time, the LLM starts to generate responses that are more aligned with what the human reviewers consider helpful, safe, and accurate. It’s essentially a "reward" system where the LLM is rewarded for generating answers that humans prefer.
