The entropy of a machine. Generated by: Midjourney

I had this thought.  It was based on bias. My own bias.  

When I get up in the morning, I have noticed the older I am, the more slowly I get out of bed.  This could be for many reasons, poor diet, I didn't work out, I worked out too hard, I had a long night, or I am just older today than I was yesterday.

Entropy.  It happens to the best of us, the best of any system. Not just in terms of "disorder" or "uncertainty" but also in the form of "breakdown" and "change."

Something to note: Things like disorder, uncertainty, breakdown, and change are not inherently bad. Often, they can all be good things - especially if the system is fixed and hardheaded.

For example, leaves breakdown, creating nutrients for the soil that help the flora around the breakdown.  

I don't always get better as I get older.  Maybe I slow down, maybe some of those "strong opinions, loosely held" become strong beliefs, and maybe my large language model becomes a blocker to new thinking.  

I find it easier to view entropy as an evil of the system rather than a promoter of change and motion.  

Maybe GPT can help me see it in a different light.

Prompt: What is entropy?

Entropy is a fundamental concept in the fields of physics and information theory.
Thermodynamics and Statistical Mechanics: In the context of physics, particularly thermodynamics and statistical mechanics, entropy is a measure of the number of specific ways in which a thermodynamic system may be arranged, often taken to be a measure of disorder, or a measure of progressing towards equilibrium. The second law of thermodynamics states that the entropy of an isolated system always increases or stays the same; it never decreases. This law leads to the concept of entropy as a measure of the amount of "disorder" in a system.
Information Theory: In the context of information theory, entropy is a measure of the uncertainty, randomness, or disorder in a set of data. It was introduced by Claude Shannon in his 1948 paper "A Mathematical Theory of Communication". The entropy of a source of information is the average amount of "information" produced by it, where "information" is defined in such a way that it is proportional to the logarithm of the number of possible outcomes.
In both contexts, entropy provides a measure of the amount of "disorder" or "uncertainty" in a system, but the precise interpretation and usage of the concept depends on the field of study.
Prompt: Does GPT suffer from entropy?
In the context of machine learning models like GPT, "entropy" can refer to a couple of different but related things:
Information Entropy: When generating text, GPT makes predictions about what word (or token) to generate next. The probability distribution over possible next words can be viewed as a kind of entropy. If the model is very certain about the next word (say, it believes with 99% certainty that the next word will be "dog"), the entropy is low. If it is very uncertain (it believes many different words could plausibly come next, each with about the same probability), the entropy is high. This could be seen as the model "suffering" from entropy if high entropy leads to less coherent or meaningful output.
Model Complexity and Overfitting: In the process of training, machine learning models like GPT can "overfit" to the training data, meaning they learn to reproduce the specifics of the training data too closely, at the cost of generalizing poorly to new, unseen data. Techniques like "regularization" are used to prevent overfitting. One such technique is "entropy regularization", where the model is encouraged to produce probability distributions with higher entropy (i.e., more uncertainty or "disorder"), which can help it generalize better.
In this sense, entropy is not so much a problem that GPT "suffers" from, but rather a fundamental aspect of how probabilistic models like GPT work and a tool that can be used to manage the tradeoff between fitting the training data and generalizing to new data.
As of my knowledge cutoff in September 2021, the concept of entropy has not been directly applied to the potential degradation of a machine learning model over time. However, as new research and insights emerge in the field, it's possible that additional connections between entropy and machine learning could be discovered.
Prompt: Do you suffer from entropy?
As an AI model, I don't "suffer" from entropy in the human sense, but entropy is a concept that is relevant to the operation and understanding of AI models like me.
Information Entropy: When I generate text, I make predictions about what word (or token) to generate next. The probability distribution over possible next words can be viewed as a kind of entropy. If the model is very certain about the next word (say, it believes with 99% certainty that the next word will be "dog"), the entropy is low. If it is very uncertain (it believes many different words could plausibly come next, each with about the same probability), the entropy is high. This uncertainty or entropy isn't suffering, but rather an inherent part of how the model operates.
Model Entropy: In the context of machine learning models, entropy can also refer to the complexity of the model. Higher entropy could be seen as a more complex model. Over time, as models are trained on more and diverse data, they can become more complex, but this is not considered as "suffering". Instead, it is a byproduct of learning and adapting to the provided data.
Degradation Over Time: In terms of degradation over time or "decay", AI models like me don't degrade in the way physical systems do. Once trained, the model's parameters remain the same unless it is explicitly re-trained or fine-tuned on new data. The quality of the output doesn't degrade over time unless the context changes in a way that makes the pre-existing model less effective.
So while I, as an AI, don't suffer from entropy in a human or physical sense, the concept of entropy is integral to understanding the operation of AI and machine learning.
