2 Machine Learning GENIE, ML Classifiers, Anomaly Detection Context Knowledge Record of Sky variability (Virtual Observatories), Massive Distributed Disk Array Robotic Hardware Wide-Field Sky Monitoring Rapid Response Telescopes, Rapid Response Telescopes, Real Time Pipeline Thinking Telescopes An Engine for Discovery in the Time Domain Goal is to Integrate Three Components

3 System Adaptability: Querying the Sky Traditional Approach Hard Wired to find specific artifacts and phenomena For example---not in previous frame, not in sky catalog, and no parallax For example---not in previous frame, not in sky catalog, and no parallax Thinking Telescope Monitoring of persistent sources for important changes in real time Adaptive processing Machine learning Anomaly detection and automated classification find more like this

4 Machine Learning Automated identification of artifacts and transients in direct and difference images. Automated identification of artifacts and transients in direct and difference images. Automated classification of celestial objects based on temporal and spectral properties. Automated classification of celestial objects based on temporal and spectral properties. Real time recognition of important deviations from normal behavior for persistent sources. Real time recognition of important deviations from normal behavior for persistent sources.

7 Raptor: Sky Monitoring with Both Eyes Open Wide-field imaging system monitors ~1300 square-deg with resolution ~35 arcsec and limiting magnitude of R~13 th in 60 seconds. ( like the rod cells of the retina ) Wide-field imaging system monitors ~1300 square-deg with resolution ~35 arcsec and limiting magnitude of R~13 th in 60 seconds. ( like the rod cells of the retina ) Each array has a fovea telescope with limiting magnitude of R~16.5 (60 sec), resolution of ~7 arcsec and Gunn g (or r) filter. Provides color, better resolution, and faster cadence light curves (cone cells of fovea) Each array has a fovea telescope with limiting magnitude of R~16.5 (60 sec), resolution of ~7 arcsec and Gunn g (or r) filter. Provides color, better resolution, and faster cadence light curves (cone cells of fovea) Rapidly slewing mount places the fovea anywhere in the field in <3 seconds. (rapid eye movement).

16 Best Solution – A Distributed Sensor Network Initial work done by military and contractors to support war fighters. Initial work done by military and contractors to support war fighters. Sensor elements are self sustaining and autonomous. Sensor elements are self sustaining and autonomous. Sensor elements gather data on environment independently. Sensor elements gather data on environment independently. Data is communicated back to a central location and collaboratively processed. Data is communicated back to a central location and collaboratively processed. Working together these elements should provide a better overall picture of the environment, than single-point sensors. Working together these elements should provide a better overall picture of the environment, than single-point sensors. Ultimate Goal – To make decisions or gain knowledge based on information fused from distributed inputs

23 Breakdown of Packet Information GCN Packets – Information varies per satellite. Packet details at TALONS Packets TID –Trigger ID (Bit field definitions, encoded & decoded at client) Imagine Instrument or Observatory systems ID Follow-up or Initial spotting Either Suspected or Confirmed target type (Nova, SN, etc.) Known or new target object 1 TrigNO 2 TID 3 TOO 4 Time 5 RA 6 DEC 7 Mag 8 MagErr 9 EOF TrigNo - Trigger (or Alert) Number For Initial Spotting, returns a 0 to Central and Central assigns a new value. For follow-up observations, Trigger number is passed as the event identifier TOO – Target of Opportunity (Bit field definitions, encoded & decoded at client) Works with TID above to define type details Defines whether this packet is for a TOO Identifies if the event is transient (approaching, or receding from event. Requested Observation Type (Spectra, Photon Counting, Any, All, etc) Requested Observation Range (FIR, Gamma, Radio, etc.). Requested imaging durations (How many seconds?) Time - Time imaged expressed in TJD RA - Target Coordinate DEC - Target Coordinate Mag - Magnitude of target MagErr - Error in Magnitude measure NOTE: RA and DEC errors are to come }
