Jasmine Codebase: Modular Research Systems

• Jasmine Codebase is a family of modular, high-impact computational infrastructures designed for diverse research domains including cybersecurity, astronomy, computer vision, astrometry, and simulation.
• It emphasizes adaptive inference, performance optimization, and extensibility through innovative strategies such as dynamic active learning, multimodal visualization, and self-supervised depth estimation.
• These codebases achieve rigorous benchmarking and reproducibility, offering open-source platforms that foster scalability, user-driven exploration, and cross-domain integration.

Jasmine Codebase is a term used in multiple research domains to designate high-impact computational infrastructures, systems, and algorithms—often open-source and reproducible—spanning active learning for cybersecurity, multimodal data exploration, self-supervised computer vision, high-precision space mission simulations, probabilistic astrometry, and large-scale world modeling. Jasmine codebases consistently emphasize adaptive inference, modular extensibility, and performance benchmarking, and have been developed in domains as varied as astronomy, robotics, machine learning, and security.

1. Distinct Jasmine Codebases Across Research Domains

The “Jasmine Codebase” appears in several research contexts, each characterized by unique algorithmic and implementation practices:

Domain	Canonical Jasmine Codebase	Reference
Cybersecurity	Hybrid dynamic active learning for intrusion detection	(Klein et al., 2021)
Astronomy/Visualization	JAvaScript Multimodal INformation Explorer (browser-based)	(Schweder et al., 30 Apr 2025)
Computer Vision	SD-based self-supervised depth estimation	(Wang et al., 20 Mar 2025)
Astrometry	Probabilistic framework for wide-field plate analysis	(Ohsawa et al., 2 Apr 2025)
Space Mission Simulation	JASMINE-imagesim (astrometry+photometry image simulator)	(Kamizuka et al., 4 Oct 2024)
World Modeling	JAX-based scalable model training platform	(Mahajan et al., 30 Oct 2025)

These platforms are not mere monolithic codebases: their commonality is in rigorously engineered modular architectures that support advanced analytics, inference, and visualization—each tailored to the underlying scientific problem and data characteristics.

2. Core Architectural Features

Jasmine codebases are designed around several architectural principles:

• Modularity and Extensibility: Systems such as JAvaScript Multimodal INformation Explorer employ nested data cubes and modal windows, allowing arbitrary addition of new fields/modalities and parallel inspection. Similarly, the JAX-based world modeling codebase (Mahajan et al., 30 Oct 2025) exposes a plug-and-play pipeline for ablation studies, supporting Genie, causal transformer, and diffusion architectures.
• Performance Optimization: In world modeling, Jasmine achieves an order-of-magnitude speedup over prior CoinRun implementations by asynchronous process-parallel data loading (Grain + ArrayRecord), FlashAttention, mixed precision (bfloat16), and deterministic JAX training (Mahajan et al., 30 Oct 2025).
• Unidirectional State Flow and User-driven Exploration: Jasmine browser explorers fix state flow from global overview to detail windows, never vice versa, emphasizing user agency in exploratory analysis (Schweder et al., 30 Apr 2025).
• Probabilistic/Adaptive Inference: Jasmine for astrometry incorporates stochastic variational inference (SVI) to optimize >30,000 parameters per orbit, efficiently modeling distortion and coordinate uncertainties (Ohsawa et al., 2 Apr 2025). In cybersecurity, Jasmine phases query batch composition dynamically according to empirical information gain via α-update rules (Klein et al., 2021).

3. Key Algorithmic and Methodological Innovations

Jasmine codebases achieve domain-specific breakthroughs through tailored methods:

• Active Learning with Dynamic Query Ratios: The Jasmine cybercrime codebase fuses uncertainty sampling, isolation forest-based anomaly scoring, and random selection with a feedback loop to learn optimal query ratios per iteration. Unlike static methods (ALADIN, etc.), this adaptivity confers robustness to drift, imbalance, and novel attacks (Klein et al., 2021).
• Multimodal and Hierarchical Data Visualization: The Jasmine multimodal explorer uses Spherinator and HiPSter frameworks to extract latent space embeddings, projecting high-dimensional astronomy datasets into interpretable 3D maps via Aladin Lite (Schweder et al., 30 Apr 2025). Data points are hierarchically organized using autoencoding and displayed as interactive cubes, supporting image-point cloud comparisons.
• Self-supervised Vision via Diffusion Priors: Jasmine innovates SD-based monocular depth estimation by combining hybrid image reconstruction (alternately reconstructing real/synthetic images to preserve prior) and the Scale-Shift GRU (aligning SD’s scale/shift-invariant output with self-supervised regime), achieving SoTA results and zero-shot generalization (Wang et al., 20 Mar 2025).
• Astrometric Plate Analysis and Distortion Correction: In wide-field astrometry, Jasmine’s probabilistic model corrects for geometric distortions using Legendre polynomial expansions, tied to reference sources, with the posterior approximation and optimization performed by JAX/numpyro SVI (Ohsawa et al., 2 Apr 2025). The approach supports sub-milliarcsecond (∼70 μas) RMS accuracy over many epochs.
• High-fidelity Simulation for Mission Feasibility: JASMINE-imagesim is a GPU-accelerated Python codebase that simulates space-based detector images accounting for PSF, attitude jitter (via PSD-driven time series), complex readout timing, intra/inter-pixel flat fields, and multiple noise sources. Detailed simulation exposes critical hardware (rolling-shutter vs. global reset) and algorithmic (stripe-specific ePSF) considerations (Kamizuka et al., 4 Oct 2024).

4. Benchmarking, Performance, and Comparative Results

Rigorous benchmarking underpins the Jasmine approach:

• World Modeling (Mahajan et al., 30 Oct 2025): Jasmine reduces CoinRun training time to <9h on single GPU vs. >100h for Jafar, with deterministic reproducibility across hundreds of accelerators.
• Active Learning (Klein et al., 2021): Jasmine outperforms static AL baselines (uncertainty, anomaly, mix, random) on F1 learning curves over NSL-KDD, NSL-KDD-rand, and UNSW-NB15 datasets, with statistically significant Wilcoxon test gains.
• Astrometry (Ohsawa et al., 2 Apr 2025): RMS positional errors validate scaling as predicted by $$\varepsilon \approx \sigma^{\text{obs}}/\sqrt{N_{\text{meas}}}$$, with reference sources limited by prior uncertainty and artificial sources approaching photon-statistics limits.
• Self-supervised Depth (Wang et al., 20 Mar 2025): Jasmine’s $\delta_1$ accuracy and robust structure preservation on KITTI, CityScape, and DrivingStereo (including weather/generalization scenarios), exceed prior supervised and zero-shot baselines.
• Image Simulation (Kamizuka et al., 4 Oct 2024): Centroiding error increases from 4 mas (ideal jitter) to ∼10 mas (realistic rolling shutter + jitter) for 12.5 mag stars.

5. Extensibility, Open Science, and Infrastructure

• Open-source availability is a constant across all Jasmine codebases, including full datasets, pretrained checkpoints, and ablation scripts (as documented for CoinRun, Atari, Doom, and JASMINE-imagesim).
• Abstract Data Browser principles allow Jasmine multimodal explorer to interface with arbitrary data pipelines and third-party APIs (TNG, HiPSter).
• Sharding and distributed training: Jasmine’s world modeling infrastructure uses Shardy, enabling near-frictionless scaling; distributed checkpointing via Orbax supports large-scale training with reproducibility (Mahajan et al., 30 Oct 2025).

7. Common Misconceptions and Objective Clarifications

• Jasmine is not a monolithic codebase: It refers to a family of rigorously constructed systems, each independently advancing state of the art in its domain.
• Not limited to astronomy or world modeling: Jasmine also encompasses cybersecurity AL, vision, and mission simulation frameworks.
• Performance claims are strictly benchmarked: Order-of-magnitude speedups, SoTA accuracy, reproducibility, and robustness are empirically demonstrated and bounded by the source data in each publication.
