[go-nuts] Graphing libraries in golang

[Daniel Whitenack]

Hi Vikram,

Great questions. In general for data related things, this is a great place to 
start looking for resources: 
https://github.com/gopherdata/resources/blob/master/tooling/README.md. that is 
a curated list that is kept up to date.

I use https://github.com/gonum/plot quite a bit and found that it has a similar 
interface to that of Matlab for plotting. The links that Sebastian gave from 
ghep are also great. Between those, bar, line, histogram, box, etc. plots are 
quick to generate.

If you want something super fancy you can of course drive JS visualizations 
(like D3) from Go.

Just let me know how I can help!

Daniel

[go-nuts] Building a neural net from scratch

[Daniel Whitenack]

Hi all. I just released a blog post about building a neural net in Go from 
scratch: http://www.datadan.io/building-a-neural-net-from-scratch-in-go/. 
Hope this is interesting for some and inspires more of this sort of thing. 
Would love to talk about it here or in the #data-science channel on Slack. 

Best,
Daniel

Hi Alex,

Thanks! Appreciate the kind words. Reach out any time if I can help with
any of your use cases, answer questions, etc.

Best,
Daniel

[go-nuts] Go data science resources and community

[Daniel Whitenack]

Hi Everyone,

There are actually a lot of people doing data science with Go or just 
interested in the idea.  We have been discussing this a good bit on the 
#data-science channel of gophers slack, but it was suggested there that a 
post here would help make more people aware of these discussion and where 
to join in (if they want to).

So on that note, please join us on gophers slack 
(https://invite.slack.golangbridge.org/) at the #data-science channel.  We 
are also working on a series of community resources for learning data 
science with Go here https://github.com/gopherds.  Specifically, if you 
have ideas about certain tutorials you would like to see and/or resources 
you would like curated, please add those as issues 
here https://github.com/gopherds/training.

Best,
Daniel

Re: [go-nuts] Re: [ANN] A Go based map reduce system (second attempt)

[Daniel Whitenack]

Henrik and David,

Yes, this is precisely what pachyderm is trying to accomplish (along with a 
built in data versioning system).  It's pretty wonderful, and I recommend 
running through their quick start guide:

[go-nuts] Re: [ANN] A Go based map reduce system (second attempt)

[Daniel Whitenack]

Chris,

This is great to see!  Nice work so far.  I enjoyed experimenting with glow 
and am excited to follow this project.  If you are able you might provide 
some updates in #data-science on gophers slack.  I know people there would 
love to hear about gleam.

Best,
Daniel

[go-nuts] Re: go-gcnl: Golang library for accessing the Google Cloud Natural Language API

[Daniel Whitenack]

Thanks Josh!

This is a nice complement to the auto generated libraries which as stated:

"Due to the auto-generated nature of this collection of libraries, complete 
APIs or specific versions can appear or go away without notice."

I added your library here:

https://github.com/gopherds/resources/blob/master/tooling/README.md#nlp

[go-nuts] Re: [ANN] Go geospatial libraries: geometries, GeoJSON, WKB, KML, PostGIS, GPX, polyline

[Daniel Whitenack]

Thanks Tom! I think it would be great to add a few of these here:

https://github.com/gopherds/resources/tree/master/tooling

where you think it is appropriate.  Would you consider submitting a PR with 
some additions?

Daniel

[go-nuts] Re: Library for NLP: counting word syllables, words, sentences

[Daniel Whitenack]

Hi Johann,

Looks like there are a good number of packages listed here:

https://github.com/gopherds/resources/blob/master/tooling/README.md#nlp

In particular, it sounds like this one has some of what you need:

https://github.com/advancedlogic/go-freeling
