Discussion of article "Third Generation Neural Networks: Deep Networks" - page 17

Hello.

In your article you mention the possibility of parallelising calculation processes with the help of the R library. Could you tell more about how to organise it for computers in a common network. As I understood for this there is no need to create a cluster with the corresponding software and make significant changes in the R script code - the library organises client-server communication. Or have I misunderstood?

I have a script which is parallelised on a local machine, but I need to use computers in a network, how can I do it?

Good day.

It is right that you knocked in a private message. I just can't keep track of the latest posts in all articles.

On paralleling. I use one computer. There were no tasks that could not be solved in a reasonable time. To use several machines you need to create a cluster (packages snow, foreach, doSnow). I have not tested this option.

If there are heavy computational tasks, it is better to outsource them to GPU. The gpuR package.

Good luck

Hi Fabio,

I'm sorry.

I do not write on MKL5.

Best regards

Hi Fabio,

What's not clear?

Hi Vladimir,

I don't have the vector of (o,h,l,c) in RStudio, How to download data in R and work with them in RStudio? when I run "head(price)" this massge shown:

> head(price)

Error in head(price) : object 'price' not found

> # The MT4 numbering bars from the most recent to oldest. The R on the contrary,

>     # from the old to the new, new bar last, then use "rev" function to reverse this.

>     price <- cbind(Open = rev(o), High = rev(h), Low = rev(l), Close = rev(c))

Error in rev(o) : object 'o' not found

Hi,

Thanks for sharing the information

On this:

save(SAE, prepr, file="SAE.model")

How we can save the prepr?

I'm afraid the one I'm saving is not the same like the one in your model.

Could you please elaborate a little bit more.

Thanks.

Hi/

I am glad that you are interested in article.
Idebugcasesfall Rterma as follows:
- Comment out everything in the start () except that inspection workRterma
- Comment out in the init () all but runRterm()

- If Rterm is up and running, sinceInit()uncommentone operator and checked. Youspecifyat whathappens operator crash. 

Thereafter easier to determine the cause crash.Usuallythere are two: the script syntax error orlack of necessarylibraries.
I again refer to Appendixto the article.

Ready to help you in the future if you tell whichfallsRterm.

Best regards

Did you manage to solve this, I got the same error too. Here is a snapshot. In my case the function RIsRunning(hR) is false in the get go. So, in the if statement it, crashes. Do we need this RIsRunning(hR) running? What does it do? Any way we could run it before hand by clicking the executable? 

How did you solve this?
