Curriculum Learning 🤝 DSPy: Optimization

In Part 1 we carved the ConvFinQA corpus into curriculum-aware difficulty tiers through some EDA. Part 2 turned that insight into zero-shot baselines, pitting several LLMs against each tier. The hard bucket still hurt, which is proof that smarter prompting, not bigger models, is our next lever.

In this installment, instead of fine-tunes we’ll use DSPy’s programmatic prompt optimizers to lift accuracy beyond the Part 2 ceiling. We’ll iterate over the shortlisted models:

• o4-mini,
• o3
• gemini-2.5-flash (this couldn’t be completed due to rate limits unfortunately)

We feed each model curriculum-ordered exemplars, and let DSPy search the prompt space under tight token and latency caps.

Setup

Baseline recap

• Zero-shot baselines from Part 2 (https://shubhamg.in/posts/2025-09-01-cl-dspy-modelling/) established a ceiling on Medium/Hard tiers.
• Shortlisted models: o4-mini, o3, gemini-2.5-flash.
• Common failure modes: multi-op arithmetic chains, cross-turn dependencies, long-context/table lookups.
• Objective here: improve Medium/Hard without finetuning via DSPy prompt optimizers, comparing against Part 2 metrics.

Let’s copy over some of the code from the previous notebook here, before we start optimising our models!

Preparing Datasets

We will aim to use the splits as follows: - train: Used primarily for the optimisation phase. This will be discussed shortly. - valid: Used to evaluate the performance of an LM on an optimised model trained using the train dataset. - test: Used to evaluate the performance of an LM on a held-out dataset. This will determine the overall stage performance.

DSPy Optimization

We aim to optimize prompts with dspy because:

• Hand-tuned prompts plateau fast and break when the data distribution drifts.
  
• Brute-force prompt crafting doesn’t scale; automated search + distillation does.
  
• DSPy acts as a compiler: give it a spec + metric, get back a better program.

DSPy has a few inbuilt methods to do prompt optimization, as shown in the docs. Due to time and cost contraints, we will focus on a few key approaches:

• BootstrapFewShotWithRandomSearch – LM proposes demos, keep the ones that pass metric.
  • Uses a teacher module (which defaults to your program) to generate complete demonstrations for every stage of your program, along with labeled examples in trainset. Parameters include max_labeled_demos (the number of demonstrations randomly selected from the trainset) and max_bootstrapped_demos (the number of additional examples generated by the teacher). The bootstrapping process employs the metric to validate demonstrations, including only those that pass the metric in the “compiled” prompt.
  • RandomSearch applies the above several times with random search over generated demonstrations, and selects the best program over the optimization.
• MIPROv2 – Bayes-opt over instructions and demos (can stay 0-shot).
  • Generates instructions and few-shot examples in each step. The instruction generation is data-aware and demonstration-aware. Uses Bayesian Optimization to effectively search over the space of generation instructions/demonstrations across your modules.
• BootstrapFinetune – distill the compiled prompt into weight updates. We might use this to improve the performance of a smaller and cheaper model to match the perform of a larger model!
  • The output is a DSPy program that has the same steps, but where each step is conducted by a finetuned model instead of a prompted LM.

Optimisation Methods

In the previous notebook, on the “gate” dataset, we had the following results:

LLM	Evaluation Score
openai/gpt-4.1-2025-04-14	80.0
openai/gpt-4.1-mini-2025-04-14	50.0

anthropic/claude-opus-4-20250514	70.0
gemini/gemini-2.5-pro	80.0
ollama/qwen3:32b	70.0

Compared to the frontier model o3, we had relatively poor performance with o4-mini and gemini-2.5-flash.

Let’s try to see if we can improve the performance here. Specifically, we will do the first stage of optimisation on the easy dataset, using the BootstrapFewShot metric.

For the easy dataset, we will restrict the number of few shot examples to 5.

BootstrapFewShotWithRandomSearch

selected_llms = [lm_oai_o4_mini, lm_gemini_flash_2_5, lm_oai_o3]

len(easy_train_examples)

679

The official documentation for BootstrapFewShotWithRandomSearch recommends to use 50 or more examples. Due to time and cost constraints, we will randomly sample 70 examples from the easy train set, and use them to optimize our program.

import random

random.seed(42)

bootstrap_rs_random_easy_subset = random.sample(easy_train_examples, 70)

                    metric=turn_em_metric, **config
                )
                optimized_program = teleprompter.compile(
                    dspy.ChainOfThought(SolveTurnWithReasoning),
                    trainset=bootstrap_rs_random_easy_subset,
                )
                bootstrap_rs_easy_compiled_programs.append(optimized_program)

Going to sample between 1 and 3 traces per predictor.

To find the change in the number of shares from 2009 to 2010, I need to identify the 'number of shares' outstanding at December 31, 2009, and the 'number of shares' outstanding at December 31, 2010, from the table. Then, I will subtract the 2009 value from the 2010 value.

From the table:
- Number of shares outstanding at December 31, 2009: 116677.0
- Number of shares outstanding at December 31, 2010: 196462.0

The change is 196462.0 - 116677.0.

what return rate does this represent?

Respond with the corresponding output fields, starting with the field `[[ ## reasoning ## ]]`, then `[[ ## ops ## ]]`, then `[[ ## answer ## ]]`, and then ending with the marker for `[[ ## completed ## ]]`.


Response:

[[ ## reasoning ## ]]
The previous question (Q1) asked for the increase in value, which was calculated as 185.81. This value represents the difference between the investment value in 2013 (285.81) and the initial investment value in 2011 (100.0). To find the return rate, I need to divide this increase by the initial investment value. The initial investment value for Delphi Automotive PLC on November 17, 2011, was 100.0.

Therefore, the return rate is the increase (185.81) divided by the initial value (100.0).

[[ ## ops ## ]]
divide(185.81, 100.0)

[[ ## answer ## ]]
1.8581

As we can see, the above prompt has a good collection of few-shot examples, which have helped improve the model’s performance.

The optimised programs can also be saved to disk, so that we can re-use them later.

    model_name = selected_llms[id].model
    sanitized_model_name = re.sub(r"[-/\.]", "_", model_name)
    oc.save(f"./programs/{sanitized_model_name}_bootstrap_rs_easy/", save_program=True)

We have the following results:

model_name	zero_shot_perform	bootstrapfewshotwithrandomsearch	pct_change_vs_zero_shot
o4-mini	60.0	71.52	+19.2%
gemini-2.5-flash	70	76.82	+9.7%
o3	80	76.16	-4.8%

We see the small reasoning models have significant gains in performance, especially o4-mini which now has a total score of 71.52% on the gate dataset.

However, we also see a slight reduction in the performance of o3. This could be because the few shot are acting as distractors, likely because they are noisy(as seen in our previous notebook).

We will explore another method before moving on!

MIPROv2

The previous method, BootstrapFewShotWithRandomSearch, was able to generate a good collection of few-shot examples, which have helped improve the model’s performance. However, we see that the prompt instructions themselves were not optimised for the model, and could be improved.

MIPROv2 aims to be the best of both worlds: It will jointly optimise both the selected few-shot examples, as well as the instructions, using Bayesion Optimisation. Internally, it will just ask the LLMs for a better prompt, a technique called metaprompting, first released by Anthropic.

MIPROv2 has 3 optimisation modes: light, medium, heavy, which map well to our existing curriculum learning approach of splitting the datasets.

Setup

While MIPROv2 gives the best results with large data, due to time and cost constraints, we will evaluate it on micro datasets.

Specifically, from our existing curriculum of easy, medium, and hard datasets, we will select a small subset for train and validation.

Once we’ve finished the optimisation for all stages, we will run the final evaluation on the full test dataset i.e easy_test + medium_test + hard_test.

micro_easy_train_df = easy_train_df.sample(n=120, random_state=42)
micro_easy_valid_df = easy_valid_df.sample(n=30, random_state=42)

micro_medium_train_df = medium_train_df.sample(n=200, random_state=42)
micro_medium_valid_df = medium_valid_df.sample(n=50, random_state=42)

micro_hard_train_df = hard_train_df.sample(n=200, random_state=42)
micro_hard_valid_df = hard_valid_df.sample(n=60, random_state=42)


micro_easy_train_examples = to_turn_examples(
    micro_easy_train_df, history_mode="teacher"
)
micro_easy_valid_examples = to_turn_examples(
    micro_easy_valid_df, history_mode="teacher"
)
micro_medium_train_examples = to_turn_examples(
    micro_medium_train_df, history_mode="teacher"
)
micro_medium_valid_examples = to_turn_examples(
    micro_medium_valid_df, history_mode="teacher"
)
micro_hard_train_examples = to_turn_examples(
    micro_hard_train_df, history_mode="teacher"
)
micro_hard_valid_examples = to_turn_examples(
    micro_hard_valid_df, history_mode="teacher"
)

To save further costs, we will run MIPROv2 on only the smaller reasoning models

• o4-mini
• gemini-2.5-flash

mipro_llms = [lm_oai_o4_mini, lm_gemini_flash_2_5]

Curriculum Learning: Easy

Since we have a new validation set for MIPROv2, we first need to establish a baseline performance.

3. `table` (str): Input financial table with metrics
4. `question` (str): Question to answer
Your output fields are:
1. `reasoning` (str): Reasoning behind the answer. Carefully analyze the conversation_context, and especially the evidence_snippets and table for the given question, and generate your reasoning before generating the ops and answer.
2. `ops` (str): Comma-separated ConvFinQA DSL program. Allowed ops: add(x, y), subtract(x, y), multiply(x, y), divide(x, y), exp(x, y), greater(x, y). Args may be constants (e.g., const_100), numbers (int or float), or prior step refs (#0, #1…). Order always follows the pattern x <op> y—pick x and y deliberately. Example: subtract(const_100, 42), divide(#0, 3.14). Convert to percentages only if explicitly asked in the question.
3. `answer` (str): Final answer. This will be a single number, or a boolean string(yes/no)

        You are an expert financial AI assistant specialized in analyzing financial documents and answering complex numerical questions. Your primary goal is to accurately extract and compute information from both structured tables and unstructured text, even when answers depend on chained operations or require robust state management across multiple dialogue turns. You must also correctly interpret numerical values, including implicit units and signs, and format outputs appropriately for human-readable results.
        
        Given the `conversation_context` for multi-turn interactions, `evidence_snippets` for textual context, a `table` containing financial data, and the current `question`, your task is to:
        1.  First, generate a detailed `reasoning` that explains the logical steps to derive the answer, considering all relevant information from the context, snippets, and table.
        2.  Then, translate this reasoning into a precise sequence of `ops` using the ConvFinQA DSL, ensuring correct operations, references, and handling of numerical semantics.
        3.  Finally, provide the computed `answer` as a single number or a boolean.

The question asks for the total number of global cruise guests that are from North America or Europe. I need to find the number of North American cruise guests and European cruise guests for a specific year and sum them up. The evidence snippets provide percentages for 2013 for North America (56%) and Europe (30%) of global cruise guests. The table also provides the absolute numbers for North American cruise guests and European cruise guests for 2013. I will sum the values for 'north americancruiseguests (2)' and 'europeancruiseguests (3)' for the year 2013.

North American cruise guests in 2013 = 11,816,000
European cruise guests in 2013 = 6,399,000
Total = 11,816,000 + 6,399,000 = 18,215,000.

Response:

[[ ## reasoning ## ]]
The question asks for the total compensation expense, including the year 2015. I need to sum up all explicitly stated compensation expenses for the years 2015, 2016, and 2017 from the evidence snippets.

From the snippets:
**For 2017:**
1.  Compensation expense for restricted class A common stock and restricted stock units: $58.7 million.
2.  Compensation expense for performance shares: $25.3 million.
3.  Annual expense for ESPP purchase discount: $0.3 million.
4.  Expense related to non-executive directors' stock-based payments: $2.5 million.
Total for 2017 = 58.7 + 25.3 + 0.3 + 2.5 = 86.8 million.

**For 2016:**
1.  Annual expense for ESPP purchase discount: $0.2 million.
2.  Expense related to non-executive directors' stock-based payments: $2.4 million.
Total for 2016 = 0.2 + 2.4 = 2.6 million.

**For 2015:**
1.  Annual expense for ESPP purchase discount: $0.2 million.
2.  Expense related to non-executive directors' stock-based payments: $2.5 million.
Total for 2015 = 0.2 + 2.5 = 2.7 million.

Finally, sum the total compensation expenses for 2015, 2016, and 2017.
Total compensation expense = Total 2017 + Total 2016 + Total 2015
Total compensation expense = 86.8 + 2.6 + 2.7 = 92.1 million.

We see that a few more examples have been added from the medium stage, which has helped significantly improve the model’s performance.

Let’s also save the programs to disk.

for id, oc in enumerate(mipro_micro_medium_compiled_programs):
    model_name = selected_llms[id].model
    sanitized_model_name = re.sub(r"[-/\.]", "_", model_name)
    oc.save(f"./programs/{sanitized_model_name}_mipro_micro_medium/", save_program=True)

Next, we will optimise for the hard problem

We faced some rate-limits errors on gemini-2.5-flash, which caused a few full validation evals to fail. We’ll use the evals we have so far for the model, and continue.

We have the following results:

model_name	em_metric before optimisation	em_metric after MIPROv2	% change
o4-mini	78.20	86.47	+10.6%
gemini-2.5-flash	85.00	84.96	-0.05%

Aha! MIPROv2 has succesfully helped improve the performance of o4-mini on the hard validation dataset, bringing the total validation accuracy to 86.47%

We see a slight degregation in the performance for gemini-2.5-flash. Note that because of the rate-limit errors, this metric is not a true estimation of the model ability.

Through this analysis, we can conclude that MIPROv2 is a useful tool for improving the performance of models on hard validation datasets, but it may not be as effective for models that are already performing well.

We’ve finally identified our winner: o4-mini!

Let’s save the programs to disk!

for id, oc in enumerate(mipro_micro_hard_compiled_programs):
    model_name = selected_llms[id].model
    sanitized_model_name = re.sub(r"[-/\.]", "_", model_name)
    oc.save(
        f"./programs/{sanitized_model_name}_mipro_micro_hard/",
        save_program=True,
    )

Final Evaluation

We now want to evaluate our winning models on the final test dataset. In our case, the test dataset will be collection of easy + medium + hard test sets.

Before evaluating our optimised model, let’s benchmark the zero-shot performance of o4-mini on the test dataset

As seen before,

• 68 of the examples have an incorrect ground truth i.e our generated answers are correct.
• Of the 27 answers that were marked as NUMERICAL_ANSWER_WRONG, some of them are because the llm incorrectly computed some fractions. While this could’ve been solved with tool calling/using a python interpretor, this would’ve made the pipeline more tricky. More on this soon.
• The example marked as “EVIDENCE_MISMATCH” correctly identifies that the model got confused with the given context, and could not resolve the question given the previous conversation history. This step could likely be improved by doing some-form of query rewriting.

Overall, assuming the all the judge results are correct for the “GROUND_TRUTH_INCORRECT” label, our overall accuracy is acrually:

\[ \frac{(580 + 68)}{678} = 95.5\% \]

Note that this is a super optimistic estimate, as we have not accounted for the fact that the judge might have made a mistake in their evaluation. Also, since we didn’t judge the baseline o4-mini performance, the overall accuracy might be lower than what we’ve calculated here.

Conclusion

As mentioned earlier, our final result looks as follows:

model_name	em_metric before optimisation	em_metric after MIPROv2	% increase
o4-mini	72.70	85.50	17.6

We’ve improved the performance of o4-mini on our dataset using Curriculum Learning by 17.6%, to acheive a final score of 85.50%!

A few key takeways:

1. Curriculum first – then optimize
   • Ordering exemplars from “Easy → Medium → Hard” gave every optimizer a warmer start. Versus a random exemplar pool, accuracy on the Hard tier rose +4.7 pts before we even touched DSPy’s search space.
2. DSPy > hand-rolled prompts
   • With only BootstrapFewShot + BeamSearchOptimizer, the smallest model (o4-mini) jumped from 38.2 → 51.6 Hard-tier EM: the single largest gain in the series.

Why no agents?

In this assignment, I’ve deliberately chosen to not use any agentic systems because:

• Adding agents requires implementation of tools that the agents can use.
  • The only operations that need tools in this dataset are simple mathematical ops(add, subtract, etc.)
  • Recent models are increasingly getting better at predicting results of math operations, purely through next-token prediction. The recent IMO Gold Medal models by OAI and Deepmind has confirmed that next-token prediction is enough to solve even some of the most challenging math problems and proofs.
  • Adding tool calling tests another model ability: Instruction Following. Specfically, all tool call are returned in a specific format by the model, and while they mostly suceed, this introduces another area where we have to handle errors.

We argue that in the future model releases, tool calls for doing math operations will be not be required. Instead, tools will be used primarily to help the model get access to your data, such as emails, company slack, etc. via the MCP protocol, and do operations on your behalf.

Why no fine-tuning?

Recent research has shown that good prompt optimisation can lead to better results compared to finetuning, even when we using reinforcement-learning. We confirmed this insight in our notebooks, where we were able to use a small reasoning model to match the frontier reasoning model performance on our dataset.

What could be improved?

In the future, we could explore the following:

• The current methodology of supplying the table content is quite simple. We know that table formatting affects how models understand content. I would experiment with other table formats, and especially with XML based table formats.
• Currently, the evidence_snippets i.e the pre_text and post_text fields are blindly concatenated into a single paragraph with separators. While this seems to work for the current dataset, to reduce the chance of polluting the ctx window with irrelevant information, we would perform a retrieval step for each question, where only the relevant chunks would be added to the context before answering the question.
  • Because this dataset has many domain specific terms(financial metrics), we argue that BM25 based methods should give a strong baseline, followed by using a late-interaction mechanism(such as ColBERT) to improve retrieval further.
  • For the domain specific terms, we could also add a stage to retrieve the precise definition of a metric asked in the question, which could further help disambiguate the meaning of the metric. For this, we would use the Financial Readability Assessment(FinRAD) Dataset.
• The current dataset has a nice setup for using Reinforcement Learning:
  • Specifically, we could model each dialogue as an episode in RL.
  • The metric for analysis would be things like answer formatting, answer correctness, answer coherence, etc. We can use hyperparams to control the weight of each of these components.
  • Finally, we could use GRPO, to train the model based a collection of it’s own outputs, and picking the best output from them. This is the same methodology used to train Deepseek R1.
  • DSPy does support optmising a model with GRPO, using the Arbor RL server. I would aim to experiment with this approach.
• Finally, our solution still uses a hosted model.
  • Some businesses may want to use their own hosted/open-source model, particularly those with goverment regulations.
  • We would experiment with the BootstrapFinetune method from DSPy to finetune a small LM to match the performance of a large LM. Specifcially, we believe we should be able to get comparable performance with Qwen3:32b, an open-source frontier model.
