QUESTION
If anyone is familiar with the AMORE package on R and can spare 5 minutes of their time, I would appreciate their help.
My problem:
I am a Neural Network/R newbie, who is attempting to train a neural network with 15 inputs and 1 output using AMORE. I am using a dataset that has 16 columns (15 columns for inputs and 1 for outputs) and 124 rows (1 row per unit).
My interpretation is that I don't need to distinguish a training set from testing set for the function to work. Instead, I have created subsets from my dataset, and then vectors from my subsets, in order to provide the 'inputs' and 'targets' for the function. However, I am not sure that I have interpreted this correctly.
The function runs without error but I remain suspicious.
This is what I wrote:
...ANSWER
Answered 2020-Aug-28 at 22:30I would suggest as an option using neural networks architecture from keras package in R. I will add an example of how to train a neural network using functions from this well-known package. We will also use rsample package in order to split our data into train and test set. Next the code:
We will use iris dataset for this example. The main libraries are keras and dplyr so check if you have installed it.
Initially, we have to prepare the data. We use rsample to split the data into train and test set so that the same proportion of target variable is kept in the subsets of data:

I have been trying to convert lines of code from Objective-C to Swift in sorting array. The codes I'm converting is our existing application in Objective-C that needs to convert to Swift. How do I translate the codes below to Swift?
This is the code I need to translate to Swift

I tried searching something here but nothing seems to fit my need. I created an SSIS package that runs a report -> Attaches it to an email and send it to a bunch of people, many times (different recipients, different files).
Due to Zapier limitations I can't create a FreshDesk ticket with attachments and that is for me a must to have so I'm exploring FreshDesk API, but I'm no c# developer. I found some examples online and now I'm trying to fit this code: FreshSamples C-Sharp Create Ticket with attachment into my existing code, hoping to pass all my variable as ticket fields '

QUESTION
I 'm pretty new to both scala and spark. I have a very dumb question. I have a dataframe that I created from elasticsearch. I'm trying to write that s3 in parquet format. below is my code block and error i'm seeing. Can a good samaritan please undumb me on this one?
...ANSWER
Answered 2019-Aug-25 at 09:29You don't need to put schema when you write data in parquet format.
When you use the append mode, you suppose that you have already data stored in the path you precise and that you want to add new data. If you want to overwrite, you can put "overwrite" instead of "append" and if the path is new you don't need to put anything.
When you write to s3, the path normally should be like this "s3://bucket/the folder"
Can you try this :
QUESTION
I am trying to compare a large number of documents in two collections. To give you an estimate, I have around 1300 documents in each of the two collections.
I want to generate a diff comparison report after comparing the two collections. I do not need to point out exactly what is missing or what new content has been added, I just need to be able to identify that there is in fact some difference between the two documents. Yes, I do have a unique identifier for each documents other than Mongo's ObjectId ("_id").
Note: I have implemented the database using the denormalized data model, which means I have embedded documents (documents within documents).
What would you say is the best way to go about implementing a solution for the same?
Thank you in advance for your time samaritans!

Answered 2019-Apr-29 at 07:00You should use $lookup and $eq on all the fields you care about.
QUESTION
I have 3 models of User, Role and UserRole with their respective controllers as UsersController, RolesController and UserRolesController.
I have a method in the UserRoles controller which I would want to access through the Users controller but I keep having errors as explained below.
I have tried various means of even moving the method def self.add_roles_to_user(user, role) from the UsersRoles controller into the UserRole model and call it but I keep having the same error.
I have gone through lots of similar questions and various blogs, including those on this platform such as Calling a method from controller, and others but to no good results.
...ANSWER
Answered 2019-Apr-23 at 08:14If it is a common function, you can define it in application controller and call it. Else you can define in helper.
Please verify Calling a method from another controller
You can use that function as a module and use it:
QUESTION
I'm looking for a good samaritan that can provide with a very basic skeleton to run a python script using Google App Engine. I have read the documentation, check on related SO questions but I'm lost with the WebApp format. All I want to do is run one python script which accepts arguments or several python scripts, 6 times a week to listen to for changes in a website and then post them to Firestore.
I understand the cron format and most of the configurations files. I'm stuck on how to arrange my files for the project, and how the url's works.
All I'm asking is a very basic sample on how to effectively run the python scripts. This is by far the best resource that I have found, but I can't really understand what is going on with this code from that site:
...ANSWER
Answered 2019-Jan-19 at 02:35The answer I mentioned still applies - you won't be able to run your scripts in a standalone manner on GAE cron, simply because the cron service is really just a set of scheduled GET requests. You may be able to achieve the same end result, but by:
- installing a skeleton app
- breaking down your scripts into code that you'd stuff into the app's handlers, with arguments passed in the request's query strings
- configuring the cron service to build and trigger those requests
You can find a Python 3 skeleton in Quickstart for Python 3 in the App Engine Standard Environment
Alternatively you could, of course, use an IaaS service instead of GAE, like Google Compute Engine, where you could run your scripts directly, with a traditional cron service.

QUESTION
An exercise in classes and objects that I was given to complete over the summer is driving me insane. I know it should be easy but for some reason, I can't get my head around it so I was hoping someone here could help? Here's the briefing:
Write a class to represent a rectangle according to the specification below:
Private members:
- double width – width of the rectangle
- double height – height of the rectangle
Public methods:
Rectangle() – default constructor which creates a rectangle of size 1 by 1
Rectangle (double w, double h) – constructor which creates a rectangle of specified width and height
double area() – calculates and returns the area of a rectangle
void scale(double factor) – scales a rectangle by a specified scale factor
Write a main program to create 3 rectangles: the first will use the default constructor, the second will be a rectangle 2 x 3 and the third will be a rectangle 4 x 6. Print out the area of each rectangle and then scale the first rectangle by 4 and the second by 0.5 and print out the new areas.
I have also included the code I have written so far:
