- DeepSTPA control loop
DeepSTPA control loop structures (grey shaded) in addition to the traditional STPA control loop (green shaded).
The horizontal axis signifies the ML lifecycle highlighting how data is being processed, while the vertical axis signifies finegrained functionalities and development activities. The solid line signifies control action, and the dashed line represents feedback information. The boxes filled with same colour represent the same artifacts but appear in different ML lifecycle stages.
- Object detection (YOLOv3) on AUVs using DeepSTPA (Control loop):
This figure shows the control loop of running example using DeepSTPA. Each purple number denotes a component-wise control structure,
while the yellow numbers show the control loop inside components.
The blue arrows suggest that the component can delve into the control loops of stage on a functionality/activity dimension.
The red solid line represents the control operation and the green solid line depicts the feedback process.
- DRL-based AEB system on AVs
This figure shows DeepSTPA control loop structures applied on a DRL-based AEB systems.
- We present our survey on 31 papers selected through a systematic literature search. We summarise and compare relevant research from five perspectives (attributes of concern, object under study, modifications to STPA, derivatives of the analysis, and process modelled as a control loop) to conclude insights.
