= Machine Learning Meeting Agenda, June 26, 5pm CST = == 1) Cost function minimization == * Cost function minimization algorithms, what has been done - simulations and experiment (Den) * NN based feedback algorithm (Masha) * Adaptive feedback LMS (Den) == 2) Finding an optimal cost function == * Creating an optimal cost function for a feedback control of a cavity, in what sense is it optimal? (Jenne) * Adaptation of a particular cost function to keep RMS of the cavity constant (Den) * How to convert lock loss minimization, actuator saturations, stability criteria and error minimization to cost function? (All) * MIMO loop tuning (Rana) == 3) Sensor blending == * Blending of GS13 and CPS, L4C and IPC for ISI and HEPI control in optimal way (Den) * [[https://intranet.aei.uni-hannover.de/geo600/geohflogbook.nsf?OpenDatabase | Pre-OMC heterodyne and DC-readout (-> p4344, 4376)]] blending or hierarchical control, is it useful? (Koji) == 4) Reinforcement learning algorithms == * Test of CARCA (Den) * Should we create a library of codes? (All) == 5) Lock acquisition states == * Correspondance to seismic motion, experience from i,eLIGO, Virgo, GEO, Tama... (Koji, Rana) * Seismic radar, k-maps, status of the project (Den) == 6) Problems to solve == * experiment - test CARCA online on an oplev (40m) * experiment - test seismic k-maps (LLO, 40m) * experiment, simulation - adaptive feedback LMS on OL (40m) * experiment - DRMI loop tuning (40m) * simulations - RL algorithm testing * simulations - NN feedback controller * simulations - tuning IFO for a particular GW source - adjust control system, squeezing angle, readout type * simulations - loops crossover tuning - suspensions, frequency stabilization
