RLIE: Rule Generation with Logistic Regression, Iterative Refinement, and Evaluation for Large Language Models
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
Core claim
RLIE learns a compact set of weighted natural-language rules through four stages: LLM-based rule generation with coverage filtering; feature construction where each sample becomes a ternary vector of rule judgments in {-1,0,+1}, with 0 marking abstention; elastic-net logistic regression that learns global weights and selects rules; and iterative refinement that feeds prediction-error hard examples back to the LLM. The central finding is that the Linear-only inference mode—using the learned weights directly as the classifier—performs best on nearly every dataset, while the three LLM-augmented modes, which receive the rules, the weights, and sometimes the model's own prediction as a reference,
What carries the argument
The central object is the ternary judgment matrix Phi^{(t)}(x_i) = (z_{i,1},...,z_{i,m}), where each z_{i,j} is the LLM's local judgment of whether rule j applies to sample i, valued +1 (positive), -1 (negative), or 0 (abstain). The mechanism is to treat these judgments as features in an elastic-net logistic regression, which provides global weighting, sparse rule selection, calibration, and a thresholded prediction. The abstention option makes rule coverage explicit, and the iterative refinement loop selects hard examples by prediction error |p_i - y_i| to drive new rule generation.
Load-bearing premise
The load-bearing premise is that the LLM's per-text judgments about whether each rule applies—yes, no, or not applicable—are accurate and consistent enough to be used as features, and the paper does not measure their reliability.
What would settle it
Replace the LLM's ternary judgments with random labels on the same datasets, or repeat the protocol with a different LLM and prompt template; if the ordering of the four inference strategies changes or the Linear-only advantage disappears, the central division-of-labor claim is specific to the particular LLM and prompt rather than a general principle.
If this is right
- For LLM-generated rule sets, the recommended inference mode is direct weighted application rather than feeding the rules back to the LLM.
- Providing learned rule weights to an LLM does not yield stable accuracy gains, so LLM internalization of probabilistic importance is unreliable.
- Even a correct reference prediction from the linear model can be overridden by the LLM under complex prompting, so LLM-augmented reasoning should not be assumed to be a safe post-hoc layer.
- The iterative refinement loop yields compact rule sets (capacity 10) that are transparent and auditable, suitable for explanation and human review.
- Because the local LLM interface is fixed, the global combiner can be swapped for more expressive probabilistic models without changing the rule-generation stage.
Where Pith is reading between the lines
- The authors do not measure the consistency or calibration of the LLM's ternary judgments; a plausible editorial extension is that the ceiling of the whole framework is set by that local judgment quality, so improving per-rule judgment reliability should transfer directly to final accuracy.
- The comparison is conducted on fixed small splits of 200 training and 200 validation samples; on larger datasets the LLM-based inference modes might close the gap, so the Linear-only conclusion may be regime-specific.
- A testable extension suggested by the abstention design is to calibrate the abstain output probabilistically (e.g., via Platt scaling) rather than treating it as a hard 0, and to check whether that lifts the linear combiner further.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes RLIE, a four-stage framework for learning weighted natural-language rule sets with LLMs: (1) an LLM generates candidate rules from training examples; (2) elastic-net logistic regression learns weights over LLM-produced ternary rule judgments; (3) iterative refinement selects hard examples and prompts the LLM to generate new or revised rules; (4) evaluation compares direct inference via the logistic model (E1) with three LLM-augmented inference strategies (E2: rules only, E3: rules + weights, E4: rules + weights + linear prediction). Experiments on six HypoBench datasets with gpt-4o-mini report accuracy and macro-F1. The central empirical claim is that E1 (Linear-only) achieves the best performance on 'nearly all' datasets, while injecting the learned rules and weights into the LLM degrades accuracy, supporting a division of labor in which LLMs handle local semantic judgments and a probabilistic combiner handles global aggregation. The paper also reports comparisons with zero-shot inference, zero-shot generation, IO Refinement, and HypoGeniC, and claims superior or competitive performance with lower variance.
Significance. If the central claim holds, the paper would provide a useful and counterintuitive empirical result: a hybrid neuro-symbolic pipeline with a simple logistic-regression combiner outperforms LLM-augmented reasoning on these tasks, and LLMs are best kept at local rule application. The framework is clear, the experiments use held-out test sets with fixed splits and repeated runs, and the paper reports mean and standard deviation for all methods. However, the evidence as presented is not yet sufficient to support the strength of the claims. The load-bearing gaps are (a) the absence of any reliability analysis for the LLM ternary judgments that serve as the only input features, (b) the lack of statistical significance testing given that several headline differences are within one standard deviation, (c) the absence of reproducible artifacts (code, full prompts, data splits, learned rule examples) and an ablation of the iterative-refinement stage, and (d) a comparison limited to LLM-based baselines that does not substantiate the claim of 'superior over all performance.' The central idea is promising, but the current manuscript needs substantial additional analysis before the conclusions ca
major comments (5)
- [Section 3.1 (Eq. 1), Section 3.2 (Eq. 2), Section 5.2] The entire pipeline rests on the LLM's ternary judgment z_{i,j}=LLM(x_i,h_j) in {−1,0,+1}. These judgments are used as the only features for logistic regression, for coverage filtering, for hard-example selection, and for E1 predictions. Yet the paper reports no reliability analysis: no repeated-call agreement, no parse-error rate, no calibration of z against true labels, and no prompt-variation experiments. If these judgments are noisy or prompt-sensitive, the learned weights, the pruning decisions, and the E1-vs-E2/E3/E4 comparison could be artifacts of one LLM and one prompt template. A minimal analysis (e.g., rerunning with alternate phrasings, reporting agreement and per-rule accuracy of z) is necessary before the 'division of labor' conclusion is supported.
- [Section 5.2, Table 2] The headline claim 'Linear-only achieves the best performance on nearly all datasets' is not backed by significance tests. In Table 2, several differences are within one standard deviation: Dreaddit accuracy (E1=69.11±1.17 vs E4=69.00±1.33), Headlines (65.56±1.50 vs 65.33±1.86), Citations (identical 59.38±3.12), and LLM Detect (58.67±2.65 vs 56.67±3.51). In Table 1, IO Refinement outperforms RLIE on Dreaddit accuracy (74.89±3.47 vs 69.11±1.17) and LLM Detect accuracy (60.33±17.32 vs 58.67±2.65). Paired bootstrap tests or repeated-measures ANOVA are needed to support 'superior performance' and 'degradation' claims.
- [Section 9, Appendix C] The reproducibility statement says code 'will be made publicly available upon publication,' and Appendix C states that prompts 'can be access after this paper is accepted.' Thus the manuscript under review provides no code, no full prompts for all six datasets, no exact data splits, and no example of a learned rule set or its weights. For a paper whose contributions are interpretability and rule quality, the absence of any concrete learned rules or weights is a substantial gap. Please include the actual prompts, data splits, and representative learned rules/weights in the appendix or supplement.
- [Section 1, Section 5.1, Table 1] The claim that RLIE 'achieves superior over all performance compared to a range of LLM-based methods' is not supported by the presented baselines. Only two LLM-based rule learners and two zero-shot LLM baselines are compared; no classical rule learning method (e.g., RIPPER, RuleFit) or standard supervised classifier is included. Even among the included methods, IO Refinement achieves higher accuracy and F1 on Dreaddit and on LLM Detect, and HypoGeniC achieves higher F1 on Retweets. The novelty claim of being 'the first' to combine LLMs with probabilistic rule learning is also not substantiated with a literature survey. Please moderate these claims or add the missing comparisons.
- [Section 3.3, Section 5] The contribution of the iterative refinement stage is not ablated. The main results compare the full RLIE pipeline with external baselines, but there is no comparison to RLIE without refinement (e.g., one-shot rule generation followed by logistic regression). Since the paper claims that error-driven refinement improves rule quality and final performance, an ablation isolating this stage is necessary to validate its role.
minor comments (6)
- [Abstract] Typo: 'Generated rules are the evaluated' should be 'Generated rules are then evaluated'; 'surprising degrade' should be 'surprisingly degrades.'
- [Section 3.1, Eq. (1)] Superscript inconsistency: z^{(1)}_{i,j} = LLM(x_i, h^{(i)}_j) should use h^{(1)}_j rather than h^{(i)}_j.
- [Table 2 caption] Typo: 'valuated' should be 'evaluated.'
- [Appendix C] The appendix only shows prompts for the Retweets task. Provide prompts for all datasets or state in the main text that they are included in a supplement. Also 'can be access' should be 'can be accessed.'
- [Figure 7, Figure 8 prompts] Minor language issue: 'you can used the weighted patterns' should be 'you can use the weighted patterns.'
- [Section 5.2] The statement that LLMs 'can be inconsistent when required to strictly adhere to complex, explicit instructions' is a general claim without a citation. Add a reference or soften the wording.
Circularity Check
No significant circularity; the paper is a standard supervised pipeline evaluated on held-out splits.
full rationale
The paper's central claims are empirical, based on a clearly separated train/validation/test protocol: rule weights are fit on S_tr with Elastic Net logistic regression, hyperparameters are selected on S_val, and all four inference strategies (E1–E4) are evaluated on S_te. E1 is a direct logistic-regression prediction from LLM ternary rule judgments; E2–E4 are different prompt conditions given those rules, weights, and/or the E1 prediction. None of these quantities is defined in terms of the target result, and no test-set information is used to fit the model. The LLM ternary judgments z_{i,j} are input features, not a predicted output; concern about their noise or prompt-sensitivity is a data-quality/robustness limitation, not a circular reduction. The discussion of 'division of labor' is an empirical interpretation of Table 2 rather than a theorem derived from its own assumptions. Self-citations occur only in related-work context (e.g., Hyperlogic) and are not load-bearing for the framework's correctness or for the empirical comparison. There is no imported uniqueness theorem, no ansatz smuggled in via self-citation, and no renaming of a known result as a new derivation. Thus the paper is self-contained in its evaluation and exhibits no circularity of the kinds enumerated.

Large Language Models (LLMs) can propose rules in natural language, sidestepping the need for a predefined predicate space in traditional rule learning. Yet many LLM-based approaches ignore interactions among rules, and the opportunity to couple LLMs with probabilistic rule learning for robust inference remains underexplored. We present RLIE, a unified framework that integrates LLMs with probabilistic modeling to learn a set of weighted rules. RLIE has four stages: (1) Rule generation, where an LLM proposes and filters candidates; (2) Logistic regression, which learns probabilistic weights for global selection and calibration; (3) Iterative refinement, which updates the rule set using prediction errors; and (4) Evaluation, which compares the weighted rule set as a direct classifier with methods that inject rules into an LLM. We evaluate multiple inference strategies on real-world datasets. Applying rules directly with their learned weights yields superior performance, whereas prompting LLMs with the rules, weights, and logistic-model outputs surprisingly degrades accuracy. This supports the view that LLMs excel at semantic generation and interpretation but are less reliable for precise probabilistic integration. RLIE clarifies the potential and limitations of LLMs for inductive reasoning and couples them with classic probabilistic rule combination methods to enable more reliable neuro-symbolic reasoning.
