medley is a R library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Pytorch applications. medley has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Medley is an R package which implements the Caruana et al., 2004 algorithm for greedy stepwise ensemble selection for regression models. The idea behind medley is to make the creation of "ensembles" or "blends" of models as simple as possible. Individual models can be produced by varying hyperparameters or input feature sets, as well as by changing the underlying model code.

            Reading XML in to a List(Of Object)
            Asked 2021-Feb-18 at 22:42

            I am having a hard time reading a XML file in to a List(Of Object) in vb.net Any help would be appreciated.

            The problem occurs when the deserialization happens. I get the following error

            System.InvalidOperationException: 'There is an error in XML document (2, 2).'

            I worked on the assumption that you cannot change any part of the Xml structure, and would prefer to change your own VB.Net code

            I renamed your class CRecord to CD as it better represents what you are loading, and the XmlDeserialization process will match the Xml name to the Class name.

            Also, I added the attribute to each of the properties as the Xml Element name is all upper case and the VB.Net property is not. You can choose not to add this attribute, but then you will need to change the property names to be all upper case to match the Xml.

            The final bit of code needed was telling the XmlSerializer class what to use for the root node:

            New XmlRootAttribute("CRecord")

            It looks like you might be missing process.env.FIREBASE_SECRET (unless you've purposefully not included it since it's a private key). I should also point out that .env* files are not suitable for storing private keys since they are bundled in your application code and are publicly accessible.

            There are a couple of ways that you can initialise the admin SDK. They are outlined on the Add the Firebase Admin SDK to your server reference guide. It looks like you are attempting to initialise the SDK without parameters, which is covered here. Basically, you need to set an environment variable (via export in your terminal, not .env files) called FIREBASE_CONFIG which is either a path to a JSON file containing your config information or is a JSON object containing your config information.

            Good luck!

            For these cases, when you're OneHot encoding the categorical variable, you want to set handle_unknown='ignore', so that unseen instances in the test set are ignored, and the output matrix has the same shape.

            I tried to test the issue and I found that I can produce the issue.

            If your paste settings in Word and Excel are set as Keep Text only then you can see that table is not in format.

            Generally when you paste using CTRL + V then it use Keep Text only formatting. I suggest you to paste the table using right click of mouse -> paste (Keep source formatting) option.

            Notepad does not have any formatting option, so we cannot fix this issue for Notepad. It looks like this is by design in MS Edge browser.

            For other work around, you can try to test the issue using MS Edge (Chromium) browser. Pasting the table will keep the formatting in Notepad, Word and Excel.

            How to handle dynamic hierarchical entities in ECS
            Asked 2019-Nov-03 at 12:25

            Here's the analogy: I have an organism which is composed of cells which can be further composed of a medley of attachments.

            What I have currently is a sort of event chain between child/parents to handle attaching and detaching components (which could affect anything along the chain) which doesn't involve ecs at all, they are functions in the entities.

            Now I've used event components already (for mouse events on objects). If I wanted the system to be pure, would I create an attach component when I attach components etc? Even then how would I get all the necessary recipients to the system that consumes the component? Is it even worth it to handle it this way instead of a chain of functions? Is there a better way?

            filter checks if the result of the filter function is "truthy" to include it in the result or not. It doesn't change the values of the elements. Here you're calling re.sub that returns a non-empty string each time.

            So your original list is unchanged. You mean a simple list comprehension:
