what do rectangles with rounded corners in the bpmn model denote?
feedforward neural network
uml activity diagrams and bpmn are two notation that can be used to model the same processes: a subset of the activity diagram elements have a similar semantic than bpmn elements, despite the smaller and less expressive set of symbols. a study showed that both types of process models appear to have the same level of readability for inexperienced users, despite the higher formal constraints of an activity diagram.

business process model and notation
event-driven process chains (epc) and bpmn are two notation with similar expressivity when process modeling is concerned. a bpmn model can be transformed into an epc model. conversely, an epc model can be transformed into a bpmn model with only a slight loss of information. a study showed that for the same process, the bpmn model may need around 40% less elements than the corresponding epc model, but with a slightly larger set of symbols. the bpmn model would therefore be easier to read. the conversion between the two notations can be automated.
