Abstract
This record contains the resources accompanying the hands-on tutorial "Diffusion Models as High-Energy Physics Surrogates", prepared for The first MLQC4FC Training School. The files are intended for educational purposes and are used in the accompanying Jupyter notebook and GitHub repository. Contents dataset_2_1_10k.hdf5 A reduced version of the Fast Calorimeter Simulation Challenge dataset 2. Contains 10,000 calorimeter showers together with their corresponding incident particle energies. The dataset has been reduced from the original 100,000 showers to make it more suitable for use during the hands-on tutorial, where participants need to download and process the data within a limited amount of time. The file retains the same data structure as the original dataset, with the following datasets: incident_energies: shape (10000, 1) showers: shape (10000, 6480) This reduced dataset is provided specifically for the tutorial and is not intended to replace the original dataset. Checkpoint files Pre-trained model checkpoints used during the tutorial to demonstrate checkpoint loading, resume training, and sample generation without requiring participants to train the model from scratch. These resources are designed for the accompanying hands-on tutorial and are not intended as a benchmark dataset. For the tutorial notebook and source code, please refer to the associated GitHub repository. Usage The reduced dataset is used by the accompanying Jupyter notebook to demonstrate the training and application of diffusion models as surrogate models for high-energy physics simulations. For the tutorial, participants should use dataset_2_1_10k.hdf5 to avoid the large download and computational requirements of the full dataset. The original dataset can be found in the Fast Calorimeter Simulation Challenge resources and should be used for full-scale studies and benchmarks.
The results are packaged in the Greenfield Startup Model (GSM), which explains the priority of startups to release the product as quickly as possible, and the need to shorten time-to-market, by speeding up the development through low-precision engineering activities.

This study investigates how Lean internal startup facilitates software product innovation in large companies and identifies its enablers and inhibitors, and shows the potential of the method-in-action framework to investigate the Lean startup approach in non-startup context.

The application of agile software methods and more recently the integration of Lean practices contribute to the trend of continuous improvement in the software industry. One such area warranting proper empirical evidence is a project’s operational efficiency when using the Kanban method. This short paper takes a new angle and explores waste in the Kanban-driven software development project context. A preliminary research model is presented for helping the consequent replication of the study. The results from the empirical analysis suggest Kanban can be an effective method in visualizing and organizing the current work, but does not prevent waste from creeping in, although the overall project outcome may be successful.

The “HardFlow” algorithm could help generative AI models produce high-quality outputs that obey strict requirements when “pretty close” doesn’t cut it.
AI may appear weightless, but every model depends on physical infrastructure. To understand responsible AI, we need to look beyond algorithms and consider the entire lifecycle of the hardware behind them. The post Responsible AI Must Consider Its Afterlife appeared first on GPT-Lab.
