@sjsrey Hi Sergio, sure, that is okay!

Good morning/ evening everyone, just in case, here is the link to our google meet room: https://meet.google.com/hqj-xbyq-sdc
and the meeting notes: https://hackmd.io/JBfyjk8MRXKByIAcnjDjBw?both

@martinfleis
Just a sanity check - we start in an hour and 40 minutes, right?
Stefanie Lumnitz
@slumnitz
@martinfleis that is when I planned on joining at least :)
jeffcsauer
@jeffcsauer
@martinfleis that's what I have on my calendar
:D
Martin Fleischmann
@martinfleis
Thanks both. I still remember my time-zone confusion during the last sprint
jeffcsauer
@jeffcsauer
np! i'm with you - somehow my microsoft and google calendars are showing different times for the meeting, so I am glad someone asked :smile:

@slumnitz
yep, same here, but no time shifts any time soon hopefully.
Henrikki Tenkanen
@HTenkanen
Ah good, I would have been there an hour early. :D
Henrikki Tenkanen
@HTenkanen
Hmm, GMT 4PM would be 6PM in Finland (in 25 minutes). So to double check, we start GMT 5PM?
jeffcsauer
@jeffcsauer
I believe so! in about 1 hr 23 min
Martin Fleischmann
@martinfleis
Ah! My bad! I think I messed up time zones again when I told you the time. Sorry!
Stefanie Lumnitz
@slumnitz
It used to be 9am PT which is in 1 1/2 hours. In our official calendar it is still at 9am PT
Henrikki Tenkanen
@HTenkanen
Thanks! Haha, no worries :D

@slumnitz
Quick question to libpysal.examples maintainers: What happened to the Guerry dataset? It seems to not be callable anymore as an example dataset for testing. Is there a workaround to accessing it currently?
Martin Fleischmann
@martinfleis
@slumnitz that'll be pysal/libpysal#364 fixed in pysal/libpysal#368
Stefanie Lumnitz
@slumnitz
Ok thank you @martinfleis! :)

@crimsoneer
All, hope it's okay to post a generic question here? I've been trying to run an ML regression over space and time, but finding that my weights object is just way too big...I only have around 5,000 spatial units, but because there are 20 time units, that's a total over 100k rows, and calculating the weights from the entire dataset means Pysal wants a 97 GB of ram to run the regression! Anychance somebody knows a way around this? I'm hoping there is a way to refer back to a weights table or similar but not spotted it in the docs or examples... (also posted to Stack Overflow https://stackoverflow.com/questions/65286471/not-enough-memory-for-time-and-spatial-lag-regression-in-pysal)
Levi John Wolf
@ljwolf
Hi @crimsoneer, the only solution I'd recommend would be (1) can you change the method argumet to something like ord or LU? (2) have you tried using the GM_Lag?
Sergio Rey
@sjsrey
@jGaboardi if you are around, i'm trying to debug the ghactions for releasing and could use another pair of eyes?
Martin Fleischmann
@martinfleis
@sjsrey you have reverted that regression fix in mapclassify in the latest commit so it is back pysal/mapclassify@f1a2757
Sergio Rey
@sjsrey
My bad @martinfleis . Will fix later today. Thanks for flagging it.

@HanwGeek

Hi, I install PySAL via pip install pysal both in Python3.7 and Python3.6. But when I import GWR, both envs tells me:

ModuleNotFoundError: No module named 'pysal.model.mgwr.gwr'

and this also occurred in other subpackage in model. However, I can get these name via autocomplete.
What can I do to deal with it?Thanks!

Sergio Rey
@sjsrey
@HanwGeek accessing model through the meta package requires import pysal.model first. Alternatively, you can directly import the mgwr package with import mgwr

yeah we just borked it a second ago
back shortly

Looks awesome!

Should all be dialed in now.

Hello All, it is an awesome library. Thank you all for putting it together. I have some questions regarding Spatial model building.
  1. How do I create Weight matrix for Test and Train Dataset?
  2. How to make prediction on the new entry?
    I am trying to access the Credit Risk of a user using intensity of point of interest data around radius of 1km.
    What i have observed is, if i aggregate the data on Hex level there is similarity in default rate among neighbours. How can I consider this in my model building
Rahul-Chittora
@Rahul-Chittora
@sjsrey Thank you. Will look into it.
Rahul-Chittora
@Rahul-Chittora
@sjsrey i went through the links that you have shared with me. I still have the same questions regarding the model building aspect. In Spatial regression there 2 ways one in which dependent variable has dependency on the neighbours and in which features are dependent on nearby features. I am unable to understand the validation part of the model and how to make new predictions

Hey Folks! Regarding PySAL and joining GSoC, i'm looking for a GSoC project to star contributing. It's great for me if the project is ML/DL/NLP related, Thanks!

Friendly reminder we have our monthly dev meeting tomorrow at 9am pst. Agenda: https://hackmd.io/ngyLh_kcSFSTqOi2sLtzlQ?view

That's great, i'm gonna wait

In the spatial gini statistic, why do we report the raw values of the decomposition and not the standardized values?
we do report the wcg_share, but not the wg_share, and (I think) the wcg_share is actually the "far differences" standardized term, not the percentage of the gini coefficent that is owed to "far" pairwise differences?
Levi John Wolf
@ljwolf
I think that would be gini.wcg/(gini.g*(2*x.mean()*n**2))?
Sergio Rey
@sjsrey
@ljwolf I think the limited reporting was because the test only needed one component, and the other was implicit. In hindsight, reporting both makes more sense.

Hi!! Everyone, I am undergrad student from India.
I checked the library and was really awesome, I am going to do my best to contribute to this library.

Hello ! I am a undergraduate student and loved the pysal library and would like to contribute towards it . I have some experience in open source development as I won the hacktoberfest hosted by github . Can somebody please guide on how I should start working
Martin Fleischmann
@martinfleis
Hi @1hitman, @sarth23. It is great to see your interest! I think the best way to start is to look into GitHub repositories of individual PySAL modules (https://github.com/pysal), find the one closest to your interests and look into issues. You will likely find some which are reasonably simple to implement as a start.
Then the optimal process is to get involved in the discussion in the issue to coordinate with others and get a bit of guidance.
