Summary: weekly mtg 20160803 (Byron, Steve, Matt, me) - mobeets/nullSpaceControl GitHub Wiki
Discussed
eliminate cursor magnitudes near 0
flow diagram for each hypothesis
- take a timestep of neural activity
Fig. 2
- uncontrolled after minimal/baseline
- but looks good otherwise
overloading of color in Fig. 2
- choose one color, use discrete gradients of color
- e.g., all green
results fig
- use 16 thetas
- alternate presentation ideas:
- for single target, column for all dims, real data only
- or for single dim, all target angles
- or ticks of means in 16x8 grid for all hyps
- smooth MORE, no jags; need to fit all hyps on same plot
- true data is thick
- and don't normalize the heights; let it go off the y-axis? or chop axis itself
results fig: mean/cov bars
- this doesn't convey the fact that NONE are good
- maybe show hab/cloud anyway? and say we'll introduce them soon?
- or just report mean errors per session
- with bars in supplemental
- and then later, show all
results fig:
- scratch bars from main figs
- add to supplemental bars with ALL hyps
- show scatter of cloud vs. hab in mean, and then another for cov
- or scatter of mean, cov as x-y axes, and show all hyps; z-score mean and covs
- this frees up results in terms of histograms
steve's special space
- check without IME? trend with learning should get stronger
- compare overlap in row spaces--explains trend with learning?
- SVD on the 2d special space to get orthogonalized basis
- i.e., take the SVD of the 10x2 mapping: (NB*NB')*RB
To discuss
- learning trend
- irrelevant/relevant
- valid spiking
learning trend
CLOUD:
HABITUAL:
irrelevant/relevant
blue is jeffy, red is lincoln
valid spiking
every latent in hypotheses is valid if this means that there exists a spike within min and max spike count that would produce that latent. so instead say a latent is valid if the mean spikes from the generative model are within 0 spikes and ~40 spikes.
for each date (rows), here's the percentage is says are invalid:
true hab cld unc base min*
12 12 6 22 4 100
13 17 16 17 0 100
0 2 1 2 0 100
1 3 2 5 0 81
8 11 8 12 0 72
If instead I use empirical min and max bounds from intuitive block...
true hab cld unc base min*
3 12 3 25 0 100
4 11 4 18 0 100
1 6 2 12 0 100
9 20 6 28 0 100
5 20 5 33 0 100
