[LiVE] Live Coding Sessions from Andreas Lauschke

There are size / capacity restrictions on this community site that I've run into (1 GB file size, and max number of attached files is 5), therefore I've moved everything on my own server. Please bookmark

Thanks for the hardware recommendations - I will look for a good GPU solution. Also, the reinforcement learning sessions sound very interesting.

POSTED BY: John McCallon

nothing in AI is boring. NOTHING! Prove me wrong :)

POSTED BY: Andreas Lauschke

"Artificial Intelligence" (AI) is just a marketing term. Designed and used to extract money from the USA military (initially) and from venture capitalists (now.) In other words, "opium for the masses" (with money.)

After a "hot period" a severe "cold period" follows. That pattern -- "pendulum swing" -- has been observed before. (A lot in general, twice just within "AI".)

Boring...

I have found your presentations very helpful, and I am looking forward to more sessions!

Are you planning to cover training neural networks with large data sets? I have been experimenting with NN training, but I am limited to smaller data sets because I do not have a local GPU. I understand it is possible to use WL script/engine with a cloud computing service (e.g. AWS, etc.) for net training. Is it also possible to bring the trained network into the local machine for further analysis? I was wondering if you could cover this in a session.

I found these lectures very informative.

On the 2016 election results I started with a simple check of the data from your website.. (Used as a dataset but displayed as normal form for insertion in this post)

Query[Total, {"votes_dem", "votes_gop"}]@results

<|"votes_dem" -> 6.357110^7, "votes_gop" -> 6.3979810^7|>

Interesting but Trump did not win the popular vote.

A simple query

Thank you.

Your entire series has been an excellent presentation of Mathematica possibilities.

POSTED BY: Douglas Kubler

my pleasure!

8th session will be Fri 20th, 5pm ET Topics: Closer look at RarerProbability, and some fundamentals of continuous distributions, applied to RarerProbability

POSTED BY: Mohammad Bahrami

probably Wed 4th.

POSTED BY: Andreas Lauschke

When is the 7th session going to be?

Thanks! Must be a bug, but I had already downloaded 006 and so now I can work through the material you covered in 005. Appreciate your webinars, which are really helpful.

POSTED BY: Stephen Sheppard

I had uploaded it earlier. It's absolutely strange. Someone had commented a while ago that a file I had uploaded was missing. I just uploaded 005 again, but now 006 is missing. I guess you can only upload six files, or some MB limit. I'll discuss with tech support, it seems there is some upload limit. Thanks for bringing this to my attention.

POSTED BY: Andreas Lauschke

Hi Andreas,

Would it be possible for you to post DatasetQueryWebScraping005.nb for download? You mention it as the notebook for the June 18 tutorial on Query and web scraping, but there is no link.

Thanks, Stephen Sheppard

Hello Andreas,

Thank you for your seminars, good balance between theory and practice. Regarding outliers, are you familiar with the false neighbours notion (Kennal, Abarbanel)? I think it is relevant and wonder how Wolfram Language would accelerate computations in this area.

Best regards,

Marek Wojcik

Dear Andreas,

Many thanks for your livecoding sessions. Often, I am not able to join them live, but I visit this post and the videos on a regular basis.

Are you planning on a livecoding session about how to manage large datasets (size near or exceeding the RAM of your computer)?

I am thinking of data streaming, processing large data sets, saving large datasets (from smaller chunks) in different formats for data exchange with other systems than Mathematica etc.

I am looking forward to learning from your next livecoding session.

Kind Regards,

Dave

done

POSTED BY: Andreas Lauschke

Hi Andreas,

You have used XETRA data in your notebook "AssocDataset002.nb". Could you please give us the corresponding URL of the csv file at Deutsche Boerse?

By the way, I highly appriciate your live coding sessions and I am waiting already for the notebook of part 3.

Viele Grüße Jürgen

Hi Andreas,

Looking forward to seeing future live coding sessions by you. Could you please also attach PSD001.nb, it is missing from the current list of attachments.

Thanks, Rohit

POSTED BY: Updating Name

sorry, I must have accidentally deleted it. It was there, I know that for sure.

POSTED BY: Andreas Lauschke

I only just tripped across your first presentation. Great, great stuff. Operators, associations and datasets have been awkward material for me, as I am "hardwired" to lists and traditional functional programming. Please continue at the level and pace you have set in the first presentation.

POSTED BY: George Ellis

Thank you very much for your constructive feedback. At this point there is no planned end date for my live coding sessions, and I expect many more sessions, as the data scientist's progression

  • data sourcing / handling / filtering / aggregation
  • application (optimization, statistics, AI / NN / ML / DL, ...)
  • pure math <--> applied math

is a sheer endless paradise for the serious analyst / data scientist who can harness the appropriate tools to make inroads. And there is no other software system that is as highly integrated as the M system, so here is the place where I will demo the applicability of the M system to tackle real-world problems with concise and intuitive code.

After a few more sessions I'll prioritize the content based on audience feedback. There are many topics relevant for the professional data scientist, so that I have to start balancing general appeal with audience requests:

parallelism in computation, compilation for speed-up, combining the two: CUDA, databases, AI, crypto, dynamic interactivity, JLink, units framework, persistence, web, cloud, ... -- I won't run out of content soon. And after a while I think it will get more math-y: advanced regression, calculus of variations, control theory, region-based computing, differential geometry, ODEs, PDEs, ... all of which should be part of the professional data scientist's arsenal -- at least their very basics, and we can't get too detailed, to keep it sufficiently general to be of interest to everyone.

POSTED BY: Andreas Lauschke

To me, this is a very encouraging and exciting trajectory of presentations. I use, awkwardly, Mathematica as my goto platform for data munging and analysis. Unfortunately, I do not have the adroitness of skills of the experts presenting for Mathematica; so I have to study carefully their code to understand sufficiently what is being done so that I can master the techniques myself. At my age, I have to fight against the rigidity of my past ways of doing things in order to grok the more useful methods. I thank you greatly for taking the time to think through how to present the Wolfram Language is a meaningful, comprehensible and sequential way for an individual primarily interested in data acquisition and analysis. (A 71 yr old hobbyist programmer).

Thank you very much for your comment. Yes, to live means to learn and to improve. When we don't learn, we bereave ourselves of opportunities to grow. Virtual Greetings!

POSTED BY: Andreas Lauschke

Thank you, I enjoyed your session and am looking forward to the next one.

POSTED BY: John Shonder

Looking forward to the 2nd live-coding session
