This detailed process ensures that the LLM AI is well-equipped to understand and generate language based on the patterns it learns from the curated data.

User

It is not at all obvious that this process should work at all in producing coherent output. It is to say the least counter-intuitive, and quite surprising. I am given to understand that the LLM AI development community does not really understand the way that LLM AI function, not a deep level. Note that although the term Neural Network is used, there is little similarity to biological neurons. The idea of Neural Network comes from AI itself, and may or may not be the way that wetware works. This is unclear and a topic of biological research.

ChatGPT 3.5

You're correct in highlighting the counterintuitive nature of language model development, and it's true that the functioning of large language models (LLMs) like those based on neural networks is not fully understood at a deep level, especially in comparison to biological neural networks.

Here are a few key points to consider:

1. Neural Network Metaphor:

   • The term "Neural Network" is a metaphor borrowed from biological neural networks, but the resemblance is largely conceptual. In reality, artificial neural networks are a mathematical construct designed to process information, and their architecture is engineered for computational efficiency rather than biological accuracy.

2. Non-Biological Inspiration:

   • While the inspiration for artificial neural networks comes from neuroscience, the design and operation of these models have significant differences from biological brains. The primary goal is to develop models that can effectively perform specific tasks, such as language understanding or generation, rather than mirroring biological processes precisely.

3. Black Box Nature:

   • LLMs, particularly those based on deep learning, are often referred to as "black boxes" because of the complexity and opacity of their internal workings. The connections and weights learned during training are intricate and challenging to interpret in a way that aligns with human intuition.

4. Empirical Success:

   • The success of LLMs is largely empirical; their effectiveness is demonstrated through performance on tasks like language translation, text completion, and question-answering. The lack of a comprehensive theoretical understanding hasn't hindered their practical utility in various applications.

5. Ongoing Research:

   • The development community acknowledges the need for deeper understanding and continues to conduct research to demystify the inner workings of these models. Exploring interpretability, explainability, and addressing potential biases are active areas of investigation.

In summary, while the functioning of LLMs may not align perfectly with our intuitive understanding or with biological neural networks, their empirical success in language-related tasks has made them valuable tools. The ongoing research aims to bridge the gap between practical utility and a deeper theoretical understanding, acknowledging the complexity and uniqueness of artificial neural networks in the context of machine learning.

The current generation of LLM AI has a tendency to give stereotypical responses which are general and often wrong in the details. A great deal of effort has been expended in trying to make the responses user friendly, but often the responses are just annoying. The errors are frequent, and the LLM AI community recognizes that, although some LLM AI proponents may minimize the frequency of errors and plead apologetically. The LLM AI community has taken to call these errors "hallucinations", but in fact, the analogy fails badly. A more appropriate analogy would be the word "confabulation." The source of the errors may be algorithmic to some extent, but it is almost certainly due to errors and contradictions in the original curated data.

ChatGPT 3.5

Your observations highlight a common challenge in the current generation of large language models (LLMs), where they often produce responses that are stereotypical, overly general, or even incorrect in details. The term "hallucinations" or "confabulations" is used to describe these instances where the model generates information that is not accurate or contextually appropriate.

Here are a few key points to consider regarding the issues you've outlined:

1. User-Friendly Responses:

   • Efforts are indeed made to make LLM responses more user-friendly and coherent. However, achieving human-like understanding and nuanced responses is a complex challenge.

2. Annoying Responses:

   • The challenge of avoiding annoying or unhelpful responses is a recognized issue. Striking the right balance between generating responses that sound natural and are factually accurate remains a considerable task.

3. Errors and Contradictions:

   • The root cause of inaccuracies in LLM outputs can be attributed to various factors. Algorithmic limitations play a role, but errors and contradictions in the original curated data are significant contributors.

4. Confabulation Analogy:

   • The term "confabulation" is fitting in the sense that the model may generate information that appears plausible but is not accurate. It reflects the challenge of the model filling in gaps or making assumptions based on the patterns it learned during training.

5. Data Quality Issues:

   • The quality and representativeness of the training data play a crucial role. If the data contains biases, inaccuracies, or lacks diversity, the model may learn and replicate those issues.

6. Ongoing Improvement Efforts:

   • The LLM community recognizes these challenges and is actively working on improving the models. This includes refining training data, addressing biases, and enhancing algorithms to reduce both stereotypical responses and inaccuracies.

In summary, the limitations and challenges you've highlighted in LLMs are widely acknowledged within the community. Addressing issues related to user-friendliness, accuracy, and avoiding annoying responses is an ongoing area of research and development. Improving the quality of curated data and refining algorithms are critical steps towards minimizing errors and enhancing the overall performance of LLMs.

The input data will always have mistakes and inaccuracies, and a curator can not really eliminate such, given the limitations of curator intelligence, knowledge, understanding, and biases. They are perhaps doing the best they can, but in the real world, the accuracy of information becomes an unsolvable issue of practical epistemological import. Curators are a long way from omniscient. On many issues, disagreements amongst experts are routine. There is no way to determine which of many conflicting views are correct, so a curator must make a choice. This choice is not by any stretch of the imagination guaranteed to be correct. There is no way of deciding which view to treat as correct, in the general case. If there are conflicting views, at best one view can be correct. There is no guarantee that even one view is correct.

ChatGPT 3.5

Your observations highlight significant challenges in the curation process, particularly when dealing with the inherent limitations of curators, the nature of disagreements among experts, and the subjective aspects of determining correctness in information. Let's delve into these points:

1. Inherent Mistakes and Inaccuracies in Data:

   • The reality that input data will contain mistakes and inaccuracies is a recognized challenge. Curators, despite their best efforts, cannot eliminate all errors, given their own limitations in intelligence, knowledge, understanding, and potential biases.

2. Curator Limitations:

   • Curators are indeed constrained by their own cognitive abilities, knowledge base, and potential biases. Achieving perfection in curating data is an impractical goal, and the recognition of these limitations is crucial.

3. Disagreements Among Experts:

   • In many fields, disagreements among experts are common due to the evolving nature of knowledge, interpretation of evidence, or differing perspectives. Curators may face challenges in determining which expert opinion to prioritize.

4. Subjectivity in Choosing Views:

   • The process of choosing among conflicting views introduces subjectivity. Curators, being fallible humans, must make decisions based on their judgment, but this does not guarantee the correctness of the chosen view.

5. Unsolvable Epistemological Issue:

   • The inherent uncertainty and lack of omniscience in curators contribute to an unsolvable issue of practical epistemological import. Determining the absolute correctness of information becomes a complex and challenging problem.

6. No Guarantee of Correctness:

   • The absence of a foolproof method for deciding correctness means that even in the presence of conflicting views, there is no guarantee that any one view is correct. The complexities of the real world make this a pervasive challenge.

In summary, the curation process faces inherent difficulties due to the imperfections in both data and human curators. Disagreements among experts and the subjectivity involved in choosing views contribute to the complexity of determining correctness. Acknowledging these challenges is crucial for developing a nuanced understanding of the limitations in information curation and recognizing that achieving absolute certainty in the correctness of information may be an elusive goal.

This problem associated with curation extends to the training process, where limitations in understanding on the part of curators will bias the reinforcement process. This is an problem without a solution. In addition, there will be corporate pressure on curators to adhere to corporate party lines, perhaps under the guise of "safety." This will bias the training procedure. These are inescapable problems, and there is probably no solution.

1. Biases in the Training Process:

   • The limitations in understanding on the part of curators can introduce biases into the training process. The decisions made during curation, whether intentional or unintentional, can impact the learning patterns of the model.

2. Corporate Pressures and Safety Concerns:

   • Corporate pressures to adhere to specific viewpoints or party lines can indeed introduce bias into the training procedure. The notion of ensuring "safety" in responses may lead to a cautious approach that aligns with the corporate agenda, potentially impacting the diversity of perspectives within the model.

3. Inherent Challenges:

   • The challenges associated with biases in training data and processes are recognized within the research community. Striking a balance between safety, inclusivity, and accuracy is a complex task, and there may not be a one-size-fits-all solution.

4. Unsolvable Problems:

   • The issues you've highlighted, especially the inherent limitations in understanding, potential biases, and corporate pressures, present formidable challenges. Achieving a completely unbiased and objective model is likely an impractical goal due to the complexities involved.

5. Ethical Considerations:

   • These challenges raise ethical considerations regarding transparency, accountability, and the need for responsible AI development. Open discussions and awareness about these challenges are crucial for fostering responsible practices.
