Tutorials

The table below contains the list of available tutorials. If you are new to Platform for Situated Intelligence, we recommend starting with the Brief Introduction, as it provides an easy introduction to the core \psi concepts, and then perusing some of the tutorials below.

Tutorial	Description
Basic Stream Operators	Provides a brief introduction to basic stream operators available in Platform for Situated Intelligence.
Writing Components	Explains how to write new components in the Platform for Situated Intelligence framework.
Pipeline Execution	Explains the basics of running \psi pipelines live, or in replay, and controlling pipeline execution.
Delivery Policies	Explains the use of delivery policies, which are an important \psi construct that allow the developer to control whether and when the messages flowing over streams get dropped. This allows the developer to configure how an application may keep up with the incoming messages when not enough computational resources are available to process every message.
Stream Fusion and Merging	Explains the operators for stream fusion, merging, and synchronization.
Interpolation and Sampling	Explains the operators for interpolation and sampling.
Windowing Operators	Explains the operators that allow buffering over streams of data.
Stream Generators	Explains stream generators and timers.
Parallel Operator	Explains Parallel, an operator that enables vector-based parallel computation and dynamic pipelines.
Intervals	Explains the Interval data type and how to work with absolute and relative time intervals.
Psi Studio	Provides an introduction to Platform for Situated Intelligence Studio.
Time Interval Annotations	Explains how to create time interval annotation streams in PsiStudio.
