[] XCORR - {compute, normalize, plot} ( ) highlight causal lags
( ) also highlight selected square for presentations use key combos like 1,2 to highlight A->B (! !) quantify instantaneous identifiability - coincidence index [x] port numpy's other convolution modes to numjs [] plot xcorr (as a function of lags) [~] plot all xcorr - excise demo code (to demo.js?) to make room for xcorr matrix - increase buffer length ( ) plot fixed-lag xcorr

  • toggleable views? ( ) add scatterplot to plotFunctions.js (!) normalize cross-corr by autocorr - be sure to try normalization strategies on reciprocal circuit - plot both normalizations! - timeflip as needed

( ) bound outputs to non-negative if noise-models are Poisson [[ ]] buffer length modification

  • may want separate xcorr buffer vs param buffer?

[[]] connect UI to parameters [x] discretize delay slider - (x) would like to impose position constraints from value constraints - ( ) would be nice to display steps on 1D slider - simple enough, model after Slider2D () noise levels () gaussian - simple to specify () can I easily swap out noise models??? [x] cycle through noise models rather than picking at random - simple global which tracks current noise index - increment it when N is pressed - [ ] adding dropdown is a bonus () main difficulty is having some sense of scale consistent across modes (x) write a set_variance() method for each generator (-) do we need a different set of slider limits depending on the type? lambda = 5.0 is much bigger than sigma=5.0 ?? - gaussian: sigma - poisson: lambda - multi-poisson: lambda, ( n=100 ) - perlin: y-scale () what keys to use? menu box? ( ) clear xcorr buffer on paramter change? [x] or on key press? - currently, clear buffer on cycling noise mode, but not other params () weights - [x] global slider - how to handle individual weight sliders? () delays - [x] global slider [x] mark delays on xcorr - implementation of delay doesnt seem to work with non-uniform scaling? (x) prove to myself delay impacts the shape of xcorr, at least in non-reciprocal circuits

  🔊 [! !] perhaps want to be able to specify the *output* noise level?
     - or even, variance of signal AND noise
     - see /slides/ for explict prediction of output noise level, ID-SNR

  *to see the impact of params:*
    - 📅 [? ?] show history of xcorr w.r.t buffer length to give a sense of identifiability 
  ! ? would be nice to overlay control directly on the xcorr!

is there any way to visualize contributions?
- color mixing model?
- plot components?

(? ?) how to measure, export results (so this can be useful quantitatively)

[] generate strucutral network model [ ] plot network edges (linear version?) - ( ) look at curved arrows from circuit-viz - drawCurveArrow in cv/plotFuns.js ( ) add textbox interface ( ) memoize unstable circuits? by saving flag for largest values per circuit ( ) instability detector [] topological sorted weight matrix don't need topo sort if previous state is used for update [x] reciprocal conncections can work!
(?) figure out adj mat convention from circuit visualizer

[] generate signal buffers ( ) get sub buffer / view [] sketch out containers for signals ( ) figure out how circuit-viz does it

[~] add edittable params [ ] use meteor to plot history of parameter [x] constrained draggable points

  • fix step increment based on value not pixel coordinate

completed

[~] sketch out GUI elements

  • see google photos
  • container for 2D slider
    • (~) refactor slider as extension of node
    • (~) add additional linear slider

[] publish & polish [x] get gh-pages up - enable setting at github, done! [] add basic user guidance () start with shortcuts panel - minimum viable product for this is an explainer paragraph at the bottom [] mr droob's showcase as inspiration he just uses simple text prompt

[x] add noise modes

  • ( ) look for qualitative differences
  • (~) add selector
  • perlin
  • gaussian
  • (sum of) Poisson

[x] import basic processing sketch structure [x] set folders, helper scripts

![x]! try any reciprocal circuit!

  • may have to bound synaptic weights

  • found interesting results which depend strongly on reciprocal strength!

  • export circuit config as inline string! (see AdjMat)

implementaiton notes:

[x] getValue is based on mouse OR unconstrained coordinates! now force position constraint before getting value [x] add frozen-vs-buffering [~] import drawWave, Points.js

  • requires gh-pages .io link to act as content-delivery-network

( ) think about theme (~) make sure variables are CSS stylable
