Frontier Benchmark & Adversarial Dataset Development for Regional Intelligence
Methodology for constructing domain-specific adversarial instruction datasets, counter-hallucination verification benchmarks, and automated alignment sets for low-resource languages.
Overview
Modern frontier language models are predominantly trained and aligned on English-centric corpora, resulting in catastrophic failure rates when operating on specialized regional terminology, administrative governance, and regional legal workflows.
At Araskova Labs, we develop proprietary evaluation datasets and adversarial stress-testing benchmarks designed to expose and eliminate linguistic hallucinations, semantic drift, and terminology fabrication.
Dataset Architecture & Curation
Our dataset engineering pipeline employs an empirical three-stage curation methodology:
1. Multi-Domain Administrative Taxonomy
- Curating 15,000+ verifiable real-world queries spanning municipal land administration, agricultural subsidy forms, civil registry documentation, and regional court orders.
- Native bilingual subject-matter expert validation with 100% human-verified ground truth references.
2. Adversarial Negative Mining
- Generating hard-negative prompts containing syntactically plausible but factually erroneous bureaucratic terminology to test model resilience against false confidence.
- Constructing dual-dialect challenge sets covering formal literary Malayalam, bureaucratic government Malayalam, and localized colloquial variations.
3. Automated Alignment & Counter-Hallucination Pairs
- Direct preference optimization (DPO) and reinforcement learning from AI feedback (RLAIF) preference pairs targeting token-level refusal when factual confidence is below 98.5%.
Benchmark Metrics & Empirical Results
We tested frontier models (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, Llama 3 70B) across our benchmark suite:
- Baseline Administrative Failure Rate: ~73.4% across leading frontier models on regional legal precision.
- Post-Alignment Fine-Tuning Performance: Reduced hallucination rate to under 4.2% when evaluating against our curated verification benchmark.
