Centralized vs Decentralized Training for Multi Agent Reinforcement Learning
What exactly are the differences in centralized and decentralized training for multi agent reinforcement learning? Is centralized learning the same as the paradigm of CTDE (centralized training and decentralized execution) that is seen in much of the multi agent RL literature? When I run centralized training , the main difference I notice is that it appears that all agents are receiving the same Q0 value, which I believe means they have the same critic. I see that both methods are used in the tutorials, so I’m trying to get a clearer picture of what the differences are and when to use one versus the other.What exactly are the differences in centralized and decentralized training for multi agent reinforcement learning?

MATLAB app designer, how to update value of a property in declared callback function
Hello all,
I am rather new to MATLAB, and therefore a little unfamiliar with the app designer, apologies in advance.
I am trying to write a code that tracks the position of a stepper motor over serial communication. Currently, I have the setup such that it will callback the readSerialData Function everytime the terminator "CR" is reached.
Ideally I would like to access the value read. I wanted to save this value to the motorPos property of the app for use in separate functions later down the line. However, from tests, it seems that the value of app.motorPos does not update and remains the initial value of 0, as defined in the startup function. While it does display the correct value in the command window (from the disp(app.arduino) function), the value of the property app.arduino seem to remain 0, when called upon in later functions.
How should I go about updating the value of property motorPos?
Thanks,

Impedance Calculator of powergui block of a three-phase filter not displaying expected results
I am not getting the expected results of Impedance Calculator function of the powergui block. I am trying to measure the frequency response of a 13th harmonic filter. The resonance frequency is 780 Hz; therefore, I would expect the imedance the lowest at 780 Hz. The powergui impedance calculator does not reflect this result.
I set the Inductance and Capacitance values to a resonance frequency of 780 Hz.
Since the filter is tuned to the 13 harmonic (780 Hz), I would expect the impedance to the lowest value at 780 Hz like I drew in the red.I am not getting the expected results of Impedance Calculator function of the powergui block.

Since the filter is tuned to the 13 harmonic (780 Hz), I would expect the impedance to the lowest value at 780 Hz like I drew in the red. I am not getting the expected results of Impedance Calculator function of the powergui block. I am trying to measure the frequency response of a 13th harmonic filter. The resonance frequency is 780 Hz; therefore, I would expect the imedance the lowest at 780 Hz. The powergui impedance calculator does not reflect this result.
I set the Inductance and Capacitance values to a resonance frequency of 780 Hz.

DWT or MODWT with custom frequency bands
Dear all,
I am analyzing time-series data with a special interest in frequency-band specific crosscorrelation. In the past, I have used modwt and modwtcorr to do so. In my example, the signal is 4001 samples long and the sampling frequency is 20 kHz. When creating the standard filterbank (dwtfilterbank), I am given 10 levels with specific bands (in Hz) [5000 10000; 2500 5000; 1250 2500; 625 1250; 312.5 625; 156.25 312.5; 78.125 156.25; 39.0625 78.125; 19.53125 39.0625; 0 19.53125], coming from the following code:
%determine number of levels
max_levels = wmaxlev(4001,’sym4′)
%design filterbank
fb_dwt = dwtfilterbank(‘SignalLength’,4001,’SamplingFrequency’,20000,’Level’,max_levels)
%extract frequency bands
bands = dwtpassbands(fb_dwt)
I have highlighted the bands of interest to me. Upon further investigation, I would be more interested in shifting these bands towards 50 – 100, 100 – 300 and 300 – 600 Hz. Is it possible to design a filterbank for modwt or dwt that considers this and permits later cross-correlation analysis (such as modwtcorr)? This would be extremely helpful for me.
Thank you very much, and best,
