 +
 +An iTwin is a virtual replica of a physical assets powered by Bentley Systems.
 +It will host all reality data linked to infrastructure project and will allow the start of AI-training job.
 +
 ==== Training job ==== ==== Training job ====
 +
 +A training job will create an AI-Detector to be used in AI Detection sidebar.
 +Relying on reality data (point cloud or images) and related annotations, it will be executed on Bentley Cloud Service.
 +
 ==== Detectors ==== ==== Detectors ====
 +
 +A detector is specific to a certain job type. The quality of the detection will depend on the similarity between your dataset and the training dataset’s description.
 +
 +A detector is a frozen model. Running on your reality data through an iTwin Capture Analysis job, it will automatically recognize elements of interest. 
 +
 +Personal detectors can be trained from AI Training sidebar and a list of generic/pre-trained detectors is available here: \\

 +
 +==== iTwin ====
 +
 +AI Training occurs on Bentley Cloud Service. An iTwin association is required to ensure reality data and related annotations are accessible to AI Training engine.
 +
 +==== Upload ====
 +
 +After iTwin association, select relevant reality data.
 +If not available, open dedicated procedure to upload reality data Select it in AI Training sidebar
 +
 +==== Cloud Reality Data ====
 +
 +Select Reality Data you want your training job to un on.
 +
 +====  Review training ====
 +
 +Review training to ensure reality data is consistent for a training job
 +
 +==== Initiate training ====
 +
 +Trigger creation of specific cloud files that will enable training-job launch
 +
 +==== Inform Bentley Support ====
 +
 +Inform Bentley support
 +Do not modify auto-generated email and send as is.
 +Reality data and related annotations will be picked up by AI Training engine.
 +An AI-detector will be shared by email at the end of the procedure.
