FailureAtlas: A Taxonomy of Failure Modes in Multi-Provider LLM Serving Infrastructure
Vishal Pandey, Gopal Singh
Multi-provider LLM gateways reverse proxies that route, load-balance, and rate-limit requests across foundation-model APIs have become critical production infrastructure. Yet the f…
ContinuityBench: A Benchmark and Systems Study of Stateful Failover in Multi-Provider LLM Routing
Vishal Pandey, Gopal Singh
In production large language model (LLM) deployments, high API availability guarantees do not equate to conversational continuity. When a primary provider experiences an outage or…
AgroSense 2.0: Cross-Modal Transformer Fusion with Geospatial Raster Integration and Interpretable Multi-Task Learning for Precision Crop Recommendation
Vishal Pandey, Rishav Tewari, Ruzina Haque Laskar
Crop recommendation systems in precision agriculture have long suffered from a fundamental modality gap: visual soil characterization and chemical nutrient profiling are typically…
Trajectory Geometry of Transformer Representations Across Layers
Vishal Pandey, Gopal Singh, Yacine Mahdid
Understanding how transformer representations evolve across layers, not merely what they encode, remains an open problem in mechanistic interpretability. We recast the transformer…
A Unified Three-Stage Machine Learning Framework for Diabetes Detection, Subtype Discrimination, and Cognitive-Metabolic Hypothesis Testing
Vishal Pandey, Ruzina Haque Laskar, Rishav Tewari
Diabetes mellitus affects over 537 million adults worldwide and remains a major challenge in preventive healthcare. Existing machine-learning studies primarily formulate diabetes p…
Variational Linear Attention: Stable Associative Memory for Long-Context Transformers
Vishal Pandey, Gopal Singh
Linear attention reduces the quadratic cost of softmax attention to , but its memory state grows as in Frobenius norm, causing progressive interfer…
