Kannan MURUGAPANDIAN

AI Systems Pre-University Researcher, DPS International School, Singapore

Kannan's research interests lie at the intersection of large language model evaluation, educational technology, and computational cryptography. His work examines the epistemic limitations of retrieval-augmented generation systems, the economics of distributed inference, and the design of auditable AI systems for pedagogical application. He is concurrently engaged in competitive informatics and cybersecurity instruction.

From Semantic Reuse to Auditable Tutoring

Research Essay, 2026

This essay develops a governance-oriented extension of the Crowdsourced Semantic Cache Network (CSCN), addressing the computational and institutional barriers to scaling AI-based tutoring. A multi-stage pipeline is introduced comprising safety screening, privacy transformation, and intent canonicalization, which relocates the unit of semantic reuse from unstructured conversational text to discrete, pedagogically aligned "tutoring nodes." The resulting architecture reduces marginal inference cost through semantic caching while preserving the transparency and auditability required for institutional oversight of Socratic AI interaction.

Essay

Open Source Summit India, 2026

This paper identifies and names Statutory Myopia, a previously undocumented failure mode in retrieval-augmented generation (RAG) systems in which language models systematically privilege retrieved statutory text over pre-trained knowledge of superseding or conflicting legal authority. Three frontier models — GPT-5, DeepSeek R1, and Gemini 2.5 Pro — were evaluated using an original harness constructed on the LegalBench corpus (three doctrinal task subsets, 239 cases, 4,302 reasoning traces) under No-RAG and Statute-Only RAG conditions.

Cracking the Code: From Caesar Ciphers to WhatsApp Encryption

STEAM Club Lecture, 2026

This lecture traces the historical development of cryptographic method from the Caesar cipher (circa 100 BC) to contemporary symmetric and asymmetric systems. It establishes the vulnerability of substitution ciphers to frequency analysis, develops the RSA cryptosystem (Rivest, Shamir, and Adleman, 1977) through a worked derivation grounded in modular arithmetic and integer factorization, and concludes with an applied analysis of the Signal Protocol underlying WhatsApp's end-to-end encryption (Curve25519, AES-256, HMAC-SHA256), including its distinction between content confidentiality and metadata exposure.

Crowdsourced Semantic Cache Network: A Distributed, User-Funded Knowledge Network for Cost-Efficient and Self-Correcting LLM Inference

Preprint, 2026 Murugapandian, Kannan

This paper formalizes a four-layer architecture (CSCN) for reducing the operational cost of large-scale LLM inference through a globally shared semantic vector database, a demand-triggered validation gate employing an LLM-as-judge mechanism, and a freemium economic model that converts user expenditure into a compounding shared knowledge resource. Closed-form cost models are derived across the empirical range of cache hit rates. Under conservative production assumptions ((N = 1{,}000{,}000) queries/day, (H = 0.40)), the architecture yields a 39.9986% reduction in raw inference expenditure; under optimistic assumptions ((H = 0.67)), reductions reach 66.9977%. Validation calls are shown to be approximately 2.8827 times less costly than full generation calls, supporting a gross margin of approximately 27.5% under paid-tier operation, with the system exhibiting positive network externalities as the shared knowledge base expands.

Preprint, 2026 Murugapandian, Kannan

This study interrogates the prevailing assumption that retrieval augmentation uniformly improves factual grounding in legal reasoning tasks. Across 239 cases drawn from three LegalBench task categories, statutory retrieval unaccompanied by case law is shown to degrade ensemble majority-vote accuracy by 9 percentage points (0.87 to 0.78), an effect most pronounced under a Textualist judicial persona (−12.1 percentage points) and within the Hearsay task (−21 percentage points), where controlling precedent was withheld. The findings indicate that incomplete retrieval can be more detrimental to legal reasoning accuracy than the absence of retrieval altogether.

Democratizing Personalized Learning Using Open Source AI

FOSSASIA Summit, 2026

This talk situates Bloom's Two Sigma Problem within the contemporary AI landscape, arguing that dependence on closed-source language models introduces material privacy risk in educational contexts. A "Glass-Box Learning Architecture" is proposed, employing locally hosted 7B-parameter open-source models fine-tuned via LoRA, augmented with verified retrieval and secondary guardrail classification, to enable cost-efficient, pedagogically Socratic AI systems.
