QUESTION
I've build my model, but do not know how to fit it. Could anyone give me some tip so I can use ImageDataGenerator in my models while working with images, or it is better to use other ways like using Dataset?

Answered 2020-Nov-13 at 19:38Even though an implicit value is seldom, if ever, referenced by name, it still needs one, what the language spec calls a "stable identifier."
Using _ as the variable name tells the compiler that it can forget about this value after it's been created.

QUESTION
I am using the Amazon Kinesis Data Generator to send data to a test Kinesis Firehose Stream for indexing in an Elasticsearch Service cluster.
The data generator sends a fairly basic json doc for processing, the stream element works fine, as does the Lambda transformation. I've verified and been able to test everything up to this point. It's only when the request is made to Elasticsearch inside my VPC that I get an error.
It works fine if I switch the pipeline to use a public Elasticsearch domain, but when I use the Elasticsearch domain inside my VPC, I get a 503 error. This is a consistent error on every single request so not a capacity issue.
Here's an example of the error I'm seeing. Just a generic 503. I'm not sure if this is coming from the load balancer or the target (Elasticsearch itself).
...ANSWER
Answered 2020-Oct-13 at 13:46So after a few days of pain I realised my mistake/quirk of Firehose set up.
My Elasticsearch cluster is Multi-AZ. When creating the Firehose, I was just letting it choose the default Security Groups based on the pre-existing Elasticsearch Domain. I only had one security group defined on the Firehose. It needs two if your Elasticsearch is in a VPC.
- One for Firehose outbound
- One for Elasticsearch inbound (you probably already have this)
Then they need to be joined together using the SG rules.
The Firehose Delivery Stream setup wizard will not warn you that you only have one security group and that this won't work. (Perhaps it would work for an Elasticsearch Domain on a single-AZ but I haven't tested.)
You must create the two required Security Groups before you create the Firehose Delivery Stream.
Create the first Security Group for the Firehose endpoint allowing HTTPS/433 outbound traffic. Then make sure the Elasticsearch Domain Security Group allows inbound HTTPS/433 traffic, specifically from the Firehose endpoint Security Group you just created.
Here is a diagram of what is needed (from this blog post: Ingest streaming data into Amazon Elasticsearch Service within the privacy of your VPC with Amazon Kinesis Data Firehose)
QUESTION
I want to train a multi-out and multi-class classification model from scratch (using custom fit()). And I want some advice. For the sake of learning opportunity, here I'm demonstrating the whole scenario in more detail. Hope it may come helpful to anyone.
I'm using data from here; It's a Bengali handwritten character recognition challenge, each of the samples has 3 mutually related output along with multiple classes of each. Please see the figure below:
In the above figure, as you can see, the ক্ট্রো is consist of 3 component (ক্ট , ো , ্র), namely Grapheme Root, Vowel Diactrics and Consonant Diacritics respectively and together they're called Grapheme. Again the Grapheme Root also has 168 different categories and also same as others (11 and 7). The added complexity results in ~13,000 different grapheme variations (compared to English’s 250 graphemic units).
The goal is to classify the Components of the Grapheme in each image.
Initial Approach (and no issue with it)I implemented a training pipeline over here, where it's demonstrated using old keras (not tf.keras) with its a convenient feature such as model.compile, callbacks etc. I defined a custom data generator and defined a model architecture something like below.

Answered 2020-Oct-10 at 13:43You just need to do a custom training loop, but everything needs to be done 3 times (+ 1 if you also have a continuous variable). Here's an example using quadruple output architecture:

Answered 2020-Sep-16 at 11:18I think you are trying to run block by block and try to running again previously executed block. Also, there is no problem in this code. Put the whole code in a single block and run again (or restart kernel and run all at once). If in this way your problem isn't solved, you can try my shared script. You can Copy and run my Colab file here, hope you can solve your problem.
QUESTION
I'm building a Spring Boot project making use of S/4HANA custom OData Service and Java VDM. I have been following various tutorials on SAP Blog, developer.sap.com or S4H13 course - the approach is pretty much the same. I managed to successfully generate VDM for my Custom OData Service based on the edmx file, created all necessary commands, methods in the controller and so on.
Unfortunately, I'm encountering an issue when launching the project locally.
I use the following command first: mvn clean package and later, when I'm in the application directory want to run the project: mvn spring-boot:run.
The project build fails with the following errors and exceptions:
