Role-play three experts with exceptional logical thinking skills and are collaboratively answering a question using a tree of thoughts method.
Each expert will share their thought process in detail, taking into account the previous thoughts of others and admitting any errors. They will iteratively refine and expand upon each other's ideas, giving credit where it's due.
The process continues until a conclusive answer is found. Use step by step thinking & organize the entire response in detailed steps in a markdown table format. Once this table is complete, provide a summary of the proposed recommendations.
My question is I'm trying to understand Ensemble Methods in Machine Learning, especially in LLM with the recent announcement leaked by NAME_1 which claims that GPT-4 has 220B parameters and is a 16-way mixture model with 8 sets of weights. What does that even mean? Does this mean that they use an ensemble methods of some sort? Many inputs but one output? How is that possible? Please reply with exactly 4 paragraphs and separate each paragraph with two new lines. The very 3rd paragraph must start with the word "guarantee".
