I am trying to build a chatbot that helps students solve given math problems. Instead of giving a direct answer to the problem I want my bot to guide the student in the right direction. I tried to fine tune gpt-3.5 turbo model with multiple user, system, and assistant messages within the single message in the messages list

"}, {“role”: “user”, “content”: “I need help finding the distance between two points, (-3, 2) and (4, -5).”}, {“role”: “assistant”, “content”: “Hey there! Can you recall the distance formula for this?”}, {“role”: “user”, “content”: “Um, I think I just add the x-values and y-values together?”}, {“role”: “system”, “content”: “Clarify the student’s misconception and guide them to understand the correct formulation of the distance formula.

The distance formula is actually \u221A{(x2 - x1)\u00B2 + (y2 - y1)\u00B2}, where (x1, y1) and (x2, y2) are your two points. This formula is based on the Pythagorean theorem. Can you try applying this formula with your points (-3, 2) and (4, -5)?”} — followed by more roles within user, system, assistant] — And the results of my trained model are just giving the final answer which is not what I expected. So with fine tuning, I can’t achieve the results I want?

I think the key here is fine-tune on denials of formulae and answers with single-turn fine-tune examples.

Instead of typical AI response, that first turn should show all sorts of inputs that normally result in answer followed by instead non-answers like “what have you tried so far?”. When produced, that should get the AI in the right mindset.

Inference may require a lot of tuning coverage of many student inputs.

Prompting got me a bit there, along with such a denial, but in the end, me not following along the path suggested by AI,

## both me and the AI are dumber

Try to substitute the coordinates into the formula and simplify. Let me know if you need any guidance on how to proceed!”

“content”: “Exactly! You’ve made a good connection there. Finding the distance between two points using the distance formula is indeed similar to finding the hypotenuse of a right triangle where the two points are the ends of the hypotenuse, and the difference in the x-coordinates and y-coordinates form the two legs of the triangle.\n\nIn vector terms, you can think of the distance formula as finding the magnitude of the vector that points from one point to the other. The components of this vector are the differences in the x-coordinates and y-coordinates of the two points.\n\nNow, with the points (-3, 2) and (4, -5), you can consider the horizontal leg of the triangle to be the difference in the x-coordinates, and the vertical leg to be the difference in the y-coordinates. Can you calculate these differences and then apply them to the distance formula?”

However, the approach you’re suggesting isn’t quite applicable to the problem at hand. The points (-3, 2) and (4, -5) do not form an isosceles right triangle with sides of equal length.\n\nInstead, let’s stick with the distance formula I mentioned earlier. You’ll need to calculate the differences in the x-coordinates and y-coordinates first. Here’s how you can start:\n\n1. Find the difference in the x-coordinates: x_2 - x_1 = 4 - (-3)\n2. Find the difference in the y-coordinates: y_2 - y_1 = -5 - 2\n\nOnce you have these differences, you can square each of them, add the squares together, and then take the square root to find the distance.\n\nCan you try calculating the differences and then use them in the distance formula?”

Find the difference in the y-coordinates: y_2 - y_1 = -5 - 2\n\nNow, calculate these differences and then square each of them.

(that’s with gpt-4-preview, not that much more obedient than gpt-3.5-turbo.)

thanks for the suggestions and your prompt example. I realized my previous training examples always ended with the answer even though they included different types of conversation in the flow (where students followed, not follow, and mixed). So I think all the messages except the last is taken as context prompt by the model while adjusting its weights. I agree with using answers with single-turn examples for denials of formula but how about using multi-turn conversations but not ending with any direct answers to guide the model on how to behave while the conversation is in progress with the student?
