Firebase Tensorflow Lite Model - firebase

I am building a Tensorflow model to predict a certain feature for each user. So, I am making a model for each user of the application. I was wondering how to I upload the Tensorflow lite model to the Firebase in such a way that each user can access the model specific to him/her. For example, let's say there are two users A and B. When A makes a call to firebase, I want to make sure A's model is called and when B uses the app, I want to make sure B's model is called.
Hope that makes sense, Could someone please tell me if there is a way to do this. Thank you!

If you have a different model for each user it wouldn't scale very well if you have a large number of users.
You can use some properties of the user as input in your model, or encode them into some embedding space then use it as part of the input, you can find more info about it here:

Then you can have a single model that works for all users.

Can Firebase ML Kit be used to detect how likely a photo contains an object present into another photo?

I would like to implement a webcrawler that would be able to, given a photo of an object, search for it in a specific website.
I'm looking into Firebase ML Kit to do the job, more specificaly the Objects detection section but it is still unclear to me if that would be the right tool.
Anyone knows how could I implement that?
Comparing photos (or searching for photos) is not a use-case that ML Kit offers a pre-built model for.
The closest I can think of is running the ML Kit label extraction model on both images, and then checking if both return the same label(s). But even then you need to have all photo's locally already.
If you want something closer, you'll have to build a model yourself. But even then, you're likely going to need to build an extensive web service that searches web sites and pre-labels a lot of images.

How to enable web users to interact with a REST API

Hi and thank you for looking into this.
(Disclaimer: I have little-to-no technical background and would like to find the least complex solution. Ideally, only "connecting" different out-of-the-box components and no coding.)
HIGH-LEVEL PROBLEM:
I have trained a model for text classification using Google AutoML. I want to make this model available on a website, ie I want to enable visitors to enter their text and to receive the model's predicted class.
CONSIDERATIONS SO FAR: AutoML allows us to deploy the model via REST API and I understand that what I want are the API's PUT and GET function (right?). Ideally, I would use some form of plug-in or script to create an input field for the user which accepts the PUT and then delivers the GET.
Are you aware of any services for this? I'm also happy to host the website in an content management system like WordPress.
I'm very open regarding other approaches to solving my problem and highly appreciate any constructive input.
Many thanks!
AutoML Documentation https://cloud.google.com/natural-language/automl/docs/predict
EDIT Jan 10 There is another question related to this and a depo is shared which supposedly provided a solution. I'm not able to access the depo but the question might help you to understand my issue. Is there a way to use Googles AutoML with JavaScript?
EDIT Jan 16 I have learned that in order to provide the input to the model the POST function could be used instead of the PUT.

Create record via client script in a relation model in App Maker

Could someone point me to documentation that shows how to create a record in a model with one to many relation via client side script.
Thanks in advance!
There are two ways of creating a new record.
1. Via a client-side script
You can do this by calling a createItem function from a widget. This link might help with that.
2. Via a server-side script
You can do this by directly creating a new record, assigning it to the relation of a model and then saving that model. This link might help with this method. By the way, it's easier to do this in a server-side script, as the guide itself says.
Since you just requested the link to official documentation, I've limited my answer to links only. Please feel free to ask if you need clarifications!

Injecting code to track events on Delphi

I have a big and old application written in Delphi version 2007 for over a decade now and in order to rewrite it I intend to understand which parts/features of it are mostly used by the majority of its users.
The idea that came up is to track objects clicks and window creations to populate a log or analytics tool like Google Analytics or Deskmetrics with quantitative and qualitative data in order to help on the decision making.
To achieve that, I'm trying to figure out what is the easiest path respecting the current version limitations. One of the possibilities I am exploring is understanding how to implement some generic code that could be somehow "injected/reflected" in a class level so all instantiated objects may among other things, call a function passing parameters that identify themselves and this function would then take action to log that info using the best tool.
The only real solution so far is copying and pasting this function call on several thousands of onClick/onCreate methods and I'd like to avoid it while I am open to all other possibilities that may come out on this thread.
Thanks!

Multivariate Testing for Sublayouts in Sitecore

Having toyed with the concept in the past, I am interested in using multivariate testing on my companies Sitecore website. There are a number of places where I feel we can definitely improve sales through the use of A/B testing in:
Running two entirely different templates to see what layouts work better for users
Running a number of different Sublayouts (forms) on the site to see which ones people are more likely to fill out
Trialling different content - Running two different sets of copy to see if users are more likely to stay on the page
I want to use the Marketing Suite within Sitecore, and I want to be able to measure who visits pages more and count, out of two or more sublayout forms, which form is used the most. Sadly, I have no experience with the OMS and am struggling to see how one actually implements these things.
Let's say I have a content item, with a bunch of sublayouts attached to it within its template. Can someone help guide me towards a way of achiving the three things I want to run multivariate testing on?
EDIT: On the subject of the two sublayouts I want to test on a template; I have two sublayouts, which are both simple ASP.NET email forms. Once a user fills in the form the contents of the form are written to a database and an email (using Sitecore.Context.Item to get an "Email From" field from the content item that runs the form).
This is where I get stuck. A number of the sublayouts I have don't seem to have any "content" that needs pulling from a data source. The only content I can see in the case of the two forms I want to test is the "Email To" fields. So, if I were to abstract those away into their own data templates, and then added those as data sources I assume that I would then have to change my code for these to stop using Sitecore.Context.Item?
The point where I get stuck is with the data sources for the Multivariate Test Variables and the data sources for the Sublayouts. If I have two data templates containing the Email fields for each, two sublayouts that contain the forms that need testing and two multivariate variables, what goes where?
I believe you can read about it in the Analytics Configuration Reference (PDF link) under section 2.2.
You essentially create a MV test that wraps over potential data sources of a sublayout. The test then randomly assigns a DataSource, so your sublayouts need to be written to work with a DataSource.
With Sitecore 8 released Multivariate Testing is now supported out of the box as well as AB Testing.
You can run two entirely different templates to see which Layout works best for the user by Page Test in Sitecore's Optimization Tool on the Launch Pad. Creating a Page Test you can select the current version of the Item then create a new Version of the Item with the different Layout. This can also be done for Content on the Page
After that you need to decide how a winner can be chosen e.g. most goals completed by users, registrations etc then Sitecore will automatically run the test for you showing A and B to various users and ultimately choose a winner based on the Test Objective. You can choose a winner mannually or let Sitecore automatically choose after a set Duration.
Creating a Mulitvariate Test on number of different Sublayouts as well as imagery, personalisation, content etc is a little more interesting. To create a Multivariate Test is done via Workflow Actions, I've posted a blog recently how to add Maultivariate Testing to workflow.
Approving with a Test will prompt Sitecore to create a Multivariate Test for all variables (Sublayouts, Content, Personalization etc). It creates an 'Experience' for every possible combination of these variables and tests them against each other.
For a more in-depth explination and guide I have recently posted a tutorial to create a Multivariate Test in Sitecore.
There are two trainings that you (and a developer on your team) should really consider attending: OMS Certified Marketer and OMS .NET Developer.
Working with a Sitecore Certified OMS .NET Developer, you will be able to accomplish your marketing objectives. This is what Sitecore Training is for!
