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
| 45de4bbd-8419-40ff-8ed7-fc065c05e34f | meteos                          |

$ neutron net-list | grep public
| 84c13e76-ced9-4142-a885-280784f1f7a3 | public  | a14de1c5-b8d4-434b-a056-9b0049b93402             |

$ 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" : "45de4bbd-8419-40ff-8ed7-fc065c05e34f",
    "master_nodes_num": 1,
    "master_flavor_id": "4",
    "worker_nodes_num": 2,
    "worker_flavor_id": "2",
    "spark_version": "1.6.0",
    "floating_ip_pool": "84c13e76-ced9-4142-a885-280784f1f7a3"
}

$ 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
| 8abc626e-2b06-4c67-9b2c-0231f0cef5b8 | private | cb58940f-859b-48c6-b92a-3861470f1fc1 20.0.0.0/26 |

$ 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": "8abc626e-2b06-4c67-9b2c-0231f0cef5b8",
    "template_id": "8b7b9b89-f119-4b9b-b9b0-31598f819f1a"
}

$ 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)

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

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"
}

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",
    "experiment_id": "91504a65-01cf-428f-81aa-596be7ca8619",
