QuantFlow: A Federated Mamba-Based Post-Transformer Foundation Model for Time-Series Forecasting

Undergraduate thesis · USTC · Supervisor: Dr. Hadaate Ullah

Problem. Forecasting models are typically trained per system, learn one narrow domain from scratch, and transfer nothing. Meanwhile, real-world training data is often fragmented and private.

Approach. A privacy-preserving univariate forecasting framework built on bidirectional Mamba state-space decoders, trading the transformer's quadratic cost for linear scaling in sequence length and memory. TSMixup augmentation (Dirichlet-weighted interpolation) expands coverage of the temporal manifold, and a probabilistic projection head trained with pinball loss emits five-quantile, uncertainty-aware forecasts.

Outcome. Competitive with strong transformer baselines on held-out series; zero-shot R² above 0.8 on four of five unseen domains at the 96-step horizon; federated training within 0.05 R² of centralized training across ten datasets, without any client sharing raw data. Published as an arXiv preprint.

Bengali BPE Tokenizer

Open-source project · 87+ stars on GitHub

Problem. Tokenizers built for English inflate Bengali text severalfold, a tax on every training run and every inference call, paid most heavily by the communities least able to afford it.

Approach. Designed and trained a Byte Pair Encoding tokenizer from scratch for Bengali and other non-Latin scripts, processing 3.4 billion characters from the CC-100 Bengali corpus into a fixed vocabulary of 8,000 subword units, with custom handling for multi-byte UTF-8 characters and complex conjuncts.

Outcome. Encodes Bengali text with 7.33× fewer tokens than GPT-2's tokenizer, significantly reducing token inflation and inference costs for under-resourced languages. The project taught me that what a model can afford to learn is decided partly at the representation layer.

LunaWave: 3D Lunar Seismic Data Visualization

Regional Champion · NASA International Space Apps Challenge 2023

Problem. Apollo-era lunar seismic data is scientifically valuable but difficult to explore in its raw archival form.

Approach. Built an interactive web application to visualize lunar seismic data sourced directly from NASA's Planetary Data System, integrating spatial overlays that map mineral composition and Bouguer gravity disturbances against seismic event locations.

Outcome. Regional Champion, NASA International Space Apps Challenge 2023 (Dhaka).
