Ashok Prasad Neupane

ML Researcher & AI Engineer · Kathmandu, Nepal

I work on reinforcement learning for generative models and LLM agents, controllable 3D generation, and efficient streaming vision-language models. I'm a founding AI engineer (1 of 2) at Elephant Intelligence, building browser-use agents, and first/co-first author on papers at CVPR 2026 Workshop and under review at ICLR, WACV, and TMLR.

B.E. in Computer Engineering, Pulchowk Campus (IOE, Tribhuvan University) — ranked 47 of 15,000+ in the national entrance exam.

iARCS: Iterative Agentic RL for Controllable 3D Scene Generation

Saugat Adhikari*, Ashok Prasad Neupane*, Pramish Paudel, Ajad Chhatkuli, Danda Pani Paudel

CVPR 2026 Workshop · extended version under review at WACV

Agentic RL that adapts a pretrained 3D scene diffusion model to natural-language constraints using LLM-written reward programs refined in a reflection loop. Task success 4.5% → 73.8% (robot reachability) over MiDiffusion; 12K generated scenes released.

Foresight: Planning Future Perception in Streaming VLMs without Retraining

Ashok Prasad Neupane* (corresponding), Dipan Bartaula*, Ankit Belbase, Saugat Adhikari, Samip Ghimire, Saroj Poudel, Binod Bhattarai, Danda Pani Paudel

Under review at ICLR

Training-free dual-stream architecture: two Siamese LLMs sharing weights and KV cache — one ingests frames, the other plans when to reason and what to check. With a frozen Qwen3-VL-8B, beats the strongest trained baseline by 9.5% on OmniPro Online; +6.7 on StreamingBench and +15.4 on OVO-Bench.

iADD: Improving Alignment and Diversity in Diffusion Policy Optimization

Ashok Prasad Neupane*, Saugat Adhikari*, Pramish Paudel, Ajad Chhatkuli, Danda Pani Paudel

Under review at TMLR

Shows late-timestep-only RL updates harm diversity and proposes incremental-timestep training with Feynman–Kac particle guidance. Rare-prompt success 24.8% → 66.9%; reward–diversity AUC 53.8% → 77.7% vs. DDPO.
