sizeless
Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.
Key features
- Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
- Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
- Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
- 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
- Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
- Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
- Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
- Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches
Best for
- A utility network operator documenting residential service connections without booking a surveyor for every site
- A contractor closing a trench the same day instead of leaving it open pending a survey appointment
- Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
- A district heating project producing as-built DWG plans for regulatory sign-off
- Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
- Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning
Weights & Biased
Weights and Biases, Inc
An AI developer platform for experiment tracking, model training/fine-tuning, model management, and GenAI evaluation.
Key features
- Experiment Tracking: Lightweight SDK to log metrics, configuration, and system metrics from any Python training script or framework, enabling run-by-run comparison and searchable project pages for reproducibility and analysis.
- Model & Artifact Versioning: Stores datasets, model checkpoints, evaluation outputs and other artifacts with metadata and version history so teams can reproduce results and deploy specific model versions reliably.
- Hyperparameter Sweeps and Tuning: Built-in sweep capabilities to orchestrate hyperparameter searches across many runs, automatically aggregate results and surface best-performing configurations.
- Rich Visualizations & Reports: Interactive dashboards and report generation for metrics, plots, media (images, audio, video), and 3D objects to analyze training behavior, compare runs, and present findings.
- Framework & Environment Agnostic Integration: Easy integration with PyTorch, TensorFlow, Keras, JAX and other frameworks via the wandb Python library, with minimal code changes to start logging experiments.
- Collaboration & Team Management: Project pages, run sharing, and gallery/report features enable teams to collaborate on experiments, review run histories, and curate reproducible ML reports.
- Production Hosting Options: Available as a cloud service or as an on-premises W&B Server for organizations that require private infrastructure and data controls in production environments.
- Artifacts Sync & External Integrations: Syncs artifacts and logs (including files created during fine-tuning workflows) and integrates with third-party services and pipelines to centralize ML lifecycle data.
- Python SDK (wandb) for logging metrics, hyperparameters, artifacts and media with minimal code changes
- Web UI with Project and Run pages for experiment comparison, dashboards and reports
- Framework-agnostic integrations (examples: PyTorch Lightning, scikit-learn, XGBoost, LightGBM) and environment-agnostic operation
- Support for logging images, videos, audio, tables, HTML, 3D objects and point clouds
- Artifact and model versioning to manage datasets, models and other files across experiments
- Collaboration features: shared reports, gallery of curated reports and synchronization with GitHub
- CLI and tooling for run management and integrations (examples: flags shown for OpenAI fine-tuning integration such as --entity, --force, --legacy)
- Integration example for OpenAI fine-tuning workflows to log fine-tune jobs, events, metrics and synced artifacts
- Lightweight integration into Python scripts — install wandb package, login (GitHub option), and add a few lines to dump logs to the project page
- Comparative experiment analysis, monitoring of training runs and support for saving run logs locally (e.g., ./wandb/run-.../logs)
Best for
- Experiment Reproducibility: Researchers and engineers log hyperparameters, metrics, and artifacts for each training run to reproduce and compare different model variants and training strategies.
- Hyperparameter Optimization: Data scientists run large-scale sweep jobs to explore hyperparameter spaces and identify configurations that maximize validation performance.
- Fine-Tuning & Evaluation Workflows: Teams fine-tune foundation models (including third-party models) and log training/evaluation outputs and events to track fine-tuning progress and performance.
- Model Lifecycle Management: ML Ops teams version datasets and model artifacts, promote validated model versions from experimentation to staging and production, and maintain an auditable record of changes.
- Collaborative Reporting & Demos: Kagglers, researchers, and engineering teams create shareable reports and visual galleries to present model results, visualizations, and qualitative outputs to stakeholders.
- Production Monitoring: Monitor model performance and drift in production by recording evaluation metrics and artifacts over time to detect regressions and trigger retraining pipelines.
- Integration with Third-Party Fine-Tuning: Use W&B to log and track fine-tuning jobs executed via third-party APIs (example: OpenAI fine-tuning) and collect synchronized artifacts, logs, and evaluation metrics.
- Tracking and comparing ML experiments across hyperparameter sweeps and model variants
- Visualizing model predictions and media-rich outputs (images, videos, audio, tables, 3D visualizations)
- Logging and managing datasets and model artifacts for reproducibility and deployment
- Collaborative reporting and sharing of model performance and experiments within teams
- Monitoring training runs from frameworks like PyTorch Lightning and integrating logs with CI/GitHub
- Integrating with LLM fine-tuning workflows (e.g., OpenAI) to log fine-tune jobs, events and evaluation metrics
