# Q-GAIN：面向机器学习与物理信息分析应用的Python包

## 速览

Q-GAIN是一个专为冷原子实验设计的Python包，集成了机器学习与物理信息分析技术。它支持分类、目标检测及基于物理度量特征识别，特别适用于玻色-爱因斯坦凝聚体（BEC）图像分析。该包采用模块化工作流，从数据加载预处理到机器学习特征识别，再到常规分析。论文通过MNIST分类、孤子检测（SolDet）和环状BEC中量子涡旋检测三个任务展示了其功能。

## 关键点

- Q-GAIN实现冷原子实验中的分类、目标检测与物理信息特征识别
- 模块化工作流：数据加载→机器学习特征识别→常规分析
- 通过MNIST分类、孤子检测和涡旋检测三个案例验证
- 基于已发布的SolDet包重构并扩展新功能

## 全文

Here we describe the quantum gas analysis and inference (Q-GAIN) Python package, which enables rapid deployment of machine learning (ML) and physics-informed analysis techniques for cold-atom experiments. Out of the box, Q-GAIN implements classification, object detection, and physics-informed metrics for feature detection in images of atomic Bose-Einstein condensates (BECs). Q-GAIN encourages a natural, module-based workflow: starting with data loading and preprocessing, followed by ML-based feature identification, and ending with conventional analysis techniques. We demonstrate this modularity by configuring Q-GAIN for three ML tasks. First, we demonstrate the basic workflow of the Q-GAIN framework by implementing the standard task of classifying handwritten digits from the MNIST dataset. Then, we re-implement our earlier soliton detection (SolDet) package in the Q-GAIN framework, enabling the detection and analysis of solitonic excitations in time-of-flight data. Finally, we develop an object-detection tool that identifies quantized vortices in images of ring-shaped BECs.
