Hi! I am Sadman. I am currently in the Computer Engineering PhD program at UCI, advised by Professor Mohammad Abdullah Al Faruque. I got my Masters from University of Wisconsin-Madison in 2024. My research focus is in autonomous systems and robotics. I am currently working on adapting vision-language-action models for planning and reasoning in autonomous systems and robotics. . In my recent projects, I have worked on multi-modal models, text analysis and generation, image analysis and generation, and state-space models.

I worked briefly at Meta focusing on networking for AI training/inferenece before starting my PhD. I also had the opporunity to intern at HPE in Summer 2023 and at Meta in Summer 2024, working on AI/HPC systems. Before coming to UW-Madison, I obtained my undergraduate major in Computer Science from Bangladesh University of Engineering and Technology and my undergraduate thesis was on Interpretable CNN .

In my free time, I can be found taking exercise, traveling places, reading non-fiction, cooking dishes and listening to music.

Text Analysis and Generation with Language Models

Course Project

Sep 2024 - Dec 2024

Implemented LM components from scratch including Transformer, RNN, Beam Search, DPR, and Tree-of-Thought. Trained and evaluated the models on sentiment analysis, autoregressive generation, retrieval and reasoning. [Code]

 
 
 
 
 

Image Analysis and Generation with Vision Models

Course Project

Sep 2024 - Dec 2024

Implemented vision models from scratch including ViT, CLIP, FCOS detection, and denoising diffusion. Trained and evaluated models on MiniPlaces(78% top5), PASCAL VOC(0.61 mAP), Flicker-8k and AFHQ datasets [Code]

 
 
 
 
 

Unsupervised Domain Adaptation for Semantic Segmentation

Course Project

Oct 2024 - Dec 2024

Implemented and improved upon a test-time normalization, AdaBN, for unsupervised domain adaptation. Trained and evaluated a U-Net for semantic segmentation on Foggy Cityscapes (0.69 DICE, 12% inc. w/ TTN). [Code]

 
 
 
 
 

Hybrid Model Architecture for Language Tasks

Course Project

Oct 2024 - Dec 2024

Developed automated parallel-block hybrid architecture search combining Transformer and Mamba model blocks. Performed auto-regressive training and fine-tuning on MAD synthetic tasks, ELI5 and SQUAD datasets. [Code]

 
 
 
 
 

Memory-efficient Low-Rank Training for Large Foundation Models

Course Project

Mar 2024 - May 2024

Integrated Parallel LoRA with GPT-2, achieving equivalent performance with 24% less parameters. Combined LoRA with a Vision Transformer(ViT) and achieved 6x speedup in convergence of test loss [Code]

 
 
 
 
 

Explaining Grokking of Overparameterized Models

Course Project

Mar 2024 - May 2024

Demonstrated loss function and weight norm behavior in different grokking (delayed generalization) scenarios. Established that training data size and batch size are key factors for determining grokking delays [Code]
