OCI

Oracle OCI AI Services

Posted on Updated on

Oracle Cloud have been introducing new AI Services over the past few months, and we see a few more appearing over the coming few months. When you look at the list you might be a little surprised that these are newly available cloud services from Oracle. You might be surprised for two main reasons. Firstly, AWS and Google have similar cloud services available for some time (many years) now, and secondly, Oracle started talking about having these cloud services many years ago. It has taken some time for these to become publicly available. Although some of these have been included in other applications and offerings from Oracle, so probably they were busy with those before making them available as stand alone services.

These can be located in your Oracle Cloud account from the hamburger menu, as shown below

As you can see most of these AI Services are listed, except for the OCI Forecasting, which is due to be added “soon”. We can also expect to have an OCI Translation services and possibly some additional ones.

  • OCI Language: This services can work with over 75 languages and allows you to detect and perform knowledge extraction from the text to include entity identification and labelling, classification of text into more than 600 categories, sentiment analysis and key phrase extraction. This can be used automate knolwedge extraction from customer feedback, product reviews, discussion forums, legal documents, etc
  • OCI Speech: Performs Speech to Text, from live streaming of speech, audio and video recordings, etc creating a transcription. It works across English, Spanish and Portuguese, with other languages to be added. A nice little feature includes Profanity filtering, allowing you to tag, remove or mask certain words
  • OCI Vision: This has two parts. The first is for processing documents, and is slightly different to OCI Language Service, in that this service looks at processing text documents in jpeg, pdf, png and tiff formats. Text information extraction is performed identifying keep terms, tables, meta-data extraction, table extraction etc. The second part of OCI Vision deals with image analysis and extracting key information from the image such as objects, people, text, image classification, scene detection, etc. You can use either the pretrained models or include your own models.
  • OCI Anomaly Detection: Although anomaly detection is available via algorithms in the Database and OCI Data Science offerings, this new services allow for someone with little programming experience to utilise an ensemble of models, including the MSET algorithm, to provide greater accuracy with identifying unusual patterns in the data.

Note: I’ve excluded some services from the above list as these have been available for some time now or have limited AI features included in them. These include OCI Data Labelling, OCI Digital Assistant.

Some of these AI Services, based on the initial release, have limited functionality and resources, but this will change over time.

OCI Data Science – Create a Project & Notebook, and Explore the Interface

Posted on Updated on

In my previous blog post I went through the steps of setting up OCI to allow you to access OCI Data Science. Those steps showed the setup and configuration for your Data Science Team.

In this post I will walk through the steps necessary to create an OCI Data Science Project and Notebook, and will then Explore the basic Notebook environment.

1 – Create a Project

From the main menu on the Oracle Cloud home page select Data Science -> Projects from the menu.

Screenshot 2020-02-12 12.07.19

Select the appropriate Compartment in the drop-down list on the left hand side of the screen. In my previous blog post I created a separate Compartment for my Data Science work and team. Then click on the Create Projects button.

Screenshot 2020-02-12 12.09.11Enter a name for your project. I called this project, ‘DS-Demo-Project’. Click Create button.

That’s the Project created.

2 – Create a Notebook

After creating a project (see above) you can not create one or many Notebook Sessions.

To create a Notebook Session click on the Create Notebook Session button (see the above image).  This will create a VM to contain your notebook and associated work. Just like all VM in Oracle Cloud, they come in various different shapes. These can be adjusted at a later time to scale up and then back down based on the work you will be performing.

The following example creates a Notebook Session using the basic VM shape. I call the Notebook ‘DS-Demo-Notebook’. I also set the Block Storage size to 50G, which is the minimum value. The VNC details have been defaulted to those assigned to the Compartment. Click Create button at the bottom of the page.

The Notebook Session VM will be created. This might take a few minutes. When created you will see a screen like the following.

3 – Open the Notebook

After completing the above steps you can now open the Notebook Session in your browser.  Either click on the Open button (see above image), or copy the link and share with your data science team.

Important: There are a few important considerations when using the Notebooks. While the session is running you will be paying for it, even if the session got terminated at the browser or you lost connect. To manage costs, you may need to stop the Notebook session. More details on this in a later post.

After clicking on the Open button, a new browser tab will open and will ask you to log-in.

After logging in you will see your Notebook.

4 – Explore the Notebook Environment

The Notebook comes pre-loaded with lots of goodies.

The menu on the left-hand side provides a directory with lots of sample Notebooks, access to the block storage and a sample getting started Notebook.

When you are ready to create your own Notebook you can click on the icon for that.

Or if you already have a Notebook, created elsewhere, you can load that into your OCI Data Science environment.

The uploaded Notebook will appear in the list on the left-hand side of the screen.

OCI Data Science – Initial Setup and Configuration

Posted on Updated on

After a very, very, very long wait (18+ months) Oracle OCI Data Science platform is now available.

But before you jump straight into using OCI Data Science, there is a little bit of setup required for your Cloud Tenancy. There is the easy simple approach and then there is the slightly more involved approach. These are

  • Simple approach. Assuming you are just going to use the root tenancy and compartment, you just need to setup a new policy to enable the use of the OCI Data Science services. This assuming you have your VNC configuration complete with NAT etc. This can be done by creating a policy with the following policy statement. After creating this you can proceed with creating your first notebook in OCI Data Science.
allow service datascience to use virtual-network-family in tenancy

  • Slightly more complicated approach. When you get into having a team based approach you will need to create some additional Oracle Cloud components to manage them and what resources are allocated to them. This involved creating Compartments, allocating users, VNCs, Policies etc. The following instructions brings you through these steps

IMPORTANT: After creating a Compartment or some of the other things listed below, and they are not displayed in the expected drop-down lists etc, then either refresh your screen or log-out and log back in again!

1. Create a Group for your Data Science Team & Add Users

The first step involves creating a Group to ‘group’ the various users who will be using the OCI Data Science services.

Go to Governance and Administration ->Identity and click on Groups.

Enter some basic descriptive information. I called my Group, ‘my-data-scientists’.

Now click on your Group in the list of Groups and add the users to the group.

You may need to create the accounts for the various users.

2. Create a Compartment for your Data Science work

Now create a new Compartment to own the network resources and the Data Science resources.

Go to Governance and Administration ->Identity and click on Compartments.

Enter some basic descriptive information. I’ve called my compartment, ‘My-DS-Compartment’.

3. Create Network for your Data Science work

Creating and setting up the VNC can be a little bit of fun. You can do it the manual way whereby you setup and configure everything. Or you can use the wizard to do this. I;m going to show the wizard approach below.

But the first thing you need to do is to select the Compartment the VNC will belong to. Select this from the drop-down list on the left hand side of the Virtual Cloud Network page. If your compartment is not listed, then log-out and log-in!

To use the wizard approach click the Networking QuickStart button.

Select the option ‘VCN with Internet Connectivity and click Start Workflow, as you will want to connect to it and to allow the service to connect to other cloud services.

Screenshot 2020-02-11 20.17.22

I called my VNC ‘My-DS-vnc’ and took the default settings. Then click the Next button.

Screenshot 2020-02-11 20.19.31

The next screen shows a summary of what will be done. Click the Create button, and all of these networking components will be created.

Screenshot 2020-02-11 20.22.39

All done with creating the VNC.

4. Create required Policies enable OCI Data Science for your Compartment

There are three policies needed to allocated the necessary resources to the various components we have just created. To create these go to Governance and Administration ->Identity and click on Policies.

Select your Compartment from the drop-down list. This should be ‘My-DS-Compartment’, then click on Create Policy.

The first policy allocates a group to a compartment for the Data Science services. I called this policy, ‘DS-Manage-Access’.

allow group My-data-scientists to manage data-science-family in compartment My-DS-Compartment

The next policy is to give the Data Science users access to the network resources. I called this policy, ‘DS-Manage-Network’.

allow group My-data-scientists to use virtual-network-family in compartment My-DS-Compartment

And the third policy is to give Data Science service access to the network resources. I called this policy, ‘DS-Network-Access’.

Job Done 🙂

You are now setup to run the OCI Data Science service.  Check out my Blog Post on creating your first OCI Data Science Notebook and exploring what is available in this Notebook.
