Recommend a Movie using Meteos

In this example, you create a prediction model which recommend a movie by using Recommendation Model.

1. Create a experiment template

Create template of experiment. Experiment is a workspace of Machine Learning.

You have to confirm a glance image id of meteos image, and a neutron network id before creating a template.

You can use a format located in python-meteosclient/sample/json/template.json

$ glance image-list | grep meteos
| a6b7de0b-10ff-462c-9c86-25c8a5622a57 | meteos                          |
$ neutron net-list | grep public
| 4222b557-6d9f-405c-b1ff-0f454d2f35bf | public  | 1f979ae3-d6b7-4d03-ba0f-9d9112581783             |
$ vim sample/json/template.json
$ cat sample/json/template.json
{
    "display_name": "example-template",
    "display_description": "This is a sample template of experiment",
    "image_id" : "a6b7de0b-10ff-462c-9c86-25c8a5622a57",
    "master_nodes_num": 1,
    "master_flavor_id": "4",
    "worker_nodes_num": 2,
    "worker_flavor_id": "2",
    "spark_version": "1.6.0",
    "floating_ip_pool": "4222b557-6d9f-405c-b1ff-0f454d2f35bf"
}
$ meteos template-create --json sample/json/template.json

2. Create a experiment from template

Create a experiment by using template created in the above step. You have to confirm a neutron private network id and create keypair before creating a template.

You can use a format located in python-meteosclient/sample/json/experiment.json

$ nova keypair-add key1 > ~/key1.pem && chmod 600 ~/key1.pem
$ neutron net-list | grep private
| e4fcc49c-48e5-48f8-9599-bb5eba1339c9 | private | e15c24a5-dfdd-4428-b27d-9827b35600c0 10.0.0.0/26 |
$ vim sample/json/experiment.json
$ cat sample/json/experiment.json
{
    "display_name": "example-experiment",
    "display_description": "This is a sample experiment",
    "key_name": "key1",
    "neutron_management_network": "e4fcc49c-48e5-48f8-9599-bb5eba1339c9",
    "template_id": "d3180a78-74cc-432d-9e9d-68640b18abae"
}
$ meteos experiment-create --json sample/json/experiment.json
+--------------------+--------------------------------------+

+--------------------+--------------------------------------+

Meteos creates a experiment using OpenStack Sahara spark plugin.

You can see a sahara cluster and nova VMs created by Meteos as below.

$ openstack dataprocessing cluster list (or sahara cluster-list)
+------------------+--------------------------------------+-------------+----------------+----------+
| Name             | Id                                   | Plugin name | Plugin version | Status   |

| cluster-fcc8d055 | 5736d157-ac7c-41de-8aca-78f7afa7e99c | spark       | 1.6.0          | Spawning |

+--------------------------------------+----------------------------+--------+------------+-------------+------------------+

3. Upload a raw data

Upload a raw data (in this example movie rating data) to OpenStack Swift.

You can use a sample data located in python-meteosclient/sample/data/recommendation_data.txt

Raw data shows "UserID", "MovieID", "Rating" from left.

$ cd sample/data/
/sample/data$ head recommendation_data.txt
1,1,4.5
1,2,1.5
1,3,5.0
1,4,2.0
2,1,5.0
2,2,1.0
2,3,4.0
2,4,1.0
3,1,1.5
3,2,4.0
/sample/data$ swift upload meteos recommendation_data.txt
recommendation_data.txt

4. Create a prediction model

In this example, User creates a Recommendation Model from swift directly.

$ vim sample/json/model_recommendation.json
$ cat sample/json/model_recommendation.json
{
    "display_name": "recommend-movie",
    "display_description": "Sample Model",
    "source_dataset_url": "swift://meteos/recommendation_data.txt",
    "model_type": "Recommendation",
    "model_params": "{'numIterations': 10}",
    "experiment_id": "91504a65-01cf-428f-81aa-596be7ca8619",
    "swift_tenant": "demo",
    "swift_username": "demo",
    "swift_password": "nova"
}
$ meteos model-create --json sample/json/model_recommendation.json

5. Predict

Create a learning job predicting a Rating of specified user to determine weather you should recommend this movie to user or not.

Specify the input value as "args" parameter.

$ vim sample/json/learning.json
$ cat sample/json/learning.json
{
    "display_name": "example-learning-job",
    "display_description": "This is a sample job",
    "model_id": "6e0f8633-fac4-46d8-a0ac-e9de00ef8b4b",
    "method": "predict",
    "args": "5,3"
}
$ meteos learning-create --json sample/json/learning.json
+-------------+--------------------------------------+
| Property    | Value                                |
