bmg is a Ruby library typically used in Database, SQL Database applications. bmg has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Bmg is a relational algebra implemented as a ruby library. It implements the Relation as First-Class Citizen paradigm contributed with Alf a few years ago. Bmg can be used to query relations in memory, from various files, SQL databases, and any data source that can be seen as serving relations. Cross data-sources joins are supported, as with Alf. For differences with Alf, see a section further down this README.

            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

            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")

            How do i link files in python?
            Asked 2021-Feb-14 at 02:56

            So my example is, I'm writing a Discord bot so that when I type a command in chat it will return the corresponding value.

            Now I'm starting off with ammo for this game, the problem being there is a fair few different types of ammo in the game. Since I am new to coding and Python I wanted to get into the habit of separating them into different .py files so my codes isn't all messed and i can jump between them easily and keep track of everything down the line.

            In my main file there isn't anything but import shotgun_1, shotgun_2. What I noticed, though, is that only shotgun_1 commands will be recognized; shotgun_2 doesn't work.

            If I remove shotgun_1 and have only import shotgun_2 then the shotgun_2 code will work and send in the chat "HI!". If i remove shotgun_2 and only use shotgun_1 then the commands of shotgun_1 work.

            Is there a way to somehow link these two files so they execute the same time?

            shotgun_1.py ...

            I would suggest not separating these two aspects into different files. shotgun_2.py does not contain any code that could not be put into shotgun_1.py. This is also why shotgun_2.py doesn't do anything when shotgun_1.py runs. Your current method imports shotgun_2.py, but it doesn't do anything after it imports. I cut out large chunks of code, but here are my edits:

            Multilingual free-text-items Text Classification for improving a recommender system
            Asked 2020-May-07 at 08:13

            To improve the recomender system for Buyer Material Groups, our company is willing to train a model using customer historial spend data. The model should be trained on historical "Short text descriptions" to predict the appropriate BMG. The dataset has more that 500.000 rows and the text descriptions are multilingual (up to 40 characters).

            1.Question: can i use supervised learning if i consider the fact that the descriptions are in multiple languages? If Yes, are classic approaches like multinomial naive bayes or SVM suitable?

            2.Question: if i want to improve the first model in case it is not performing well, and use unsupervised multilingual emdedding to build a classifier. how can i train this classifier on the numerical labels later?

            if you have other ideas or approaches please feel free :). (It is a matter of a simple text classification problem)

            Can I use supervised learning if i consider the fact that the descriptions are in multiple languages?

            Yes, this is not a problem except it makes your data more sparse. If you actually only have 40 characters (is that not 40 words?) per item, you may not have enough data. Also the main challenge for supervised learning will be whether you have labels for the data.

            If Yes, are classic approaches like multinomial naive bayes or SVM suitable?

            They will work as well as they always have, though these days building a vector representation is probably a better choice.

            If i want to improve the first model in case it is not performing well, and use unsupervised multilingual emdedding to build a classifier. how can i train this classifier on the numerical labels later?

            Assuming the numerical labels are labels on the original data, you can add them as tokens like LABEL001 and the model can learn representations of them if you want to make an unsupervised recommender.

            Honestly these days I wouldn't start with Naive Bayes or classical models, I'd go straight to word vectors as a first test for clustering. Using fasttext or word2vec is pretty straightforward. The main problem is that if you really only have 40 characters per item, that just might not be enough data to cluster usefully.
