# DXC Industrialized AI Starter

DXC Industrialized AI Starter makes it easy for you to deploy your AI algorithms (Industrialize). If you are a data scientist, working on an algorithm that you would like to deploy across the enterprise, DXC's Industrialized AI starter makes it easier for you to:

- Access, clean, and explore raw data
- Build data pipelines
- Run AI experiments
- Publish microservices

## Installation

In order to  install and use the DXC AI Starter library, please use the below code snippet:
```python
1. pip install DXC-Industrialized-AI-Starter
2. from dxc import ai
```

## Getting Started

### Access, Clean, and Explore Raw Data

Use the library to access, clean, and explore your raw data.

``` python
#Access raw data
df = ai.read_data_frame_from_remote_json(json_url)
df = ai.read_data_frame_from_remote_csv(csv_url)
df = ai.read_data_frame_from_local_json()
df = ai.read_data_frame_from_local_csv()
df = ai.read_data_frame_from_local_excel_file()

#Clean data: Imputes missing data, removes empty rows and columns, anonymizes text.
raw_data = ai.clean_dataframe(df)

#Explore complete data as a HTML interactive report
report = ai.explore_complete_data(df)
report.to_notebook_iframe()

#Explore raw data: 
ai.visualize_missing_data(raw_data) #visualizes relationships between all features in data.
ai.explore_features(raw_data) #creates a visual display of missing data.
ai.plot_distributions(raw_data) #creates a distribution graph for each column.
```

### Build Data Pipelines

Pipelines are a standard way to process your data towards modeling and interpreting. By default, the DXC AI Starter library uses the free tier of [MongoDB Atlas](https://account.mongodb.com/account/register) to store raw data and execute pipelines. In order to get started, you need to first have an  <a href= "https://account.mongodb.com/account/register" target="_blank">MongoDB</a> account which you can signup for free and create a database "connection_string" and specify those details in the data_layer below. The following code connects to MongoDB and stores raw data for processing.

```python
#Insert data into MongoDB:
data_layer = {
    "connection_string": "<your connection_string>",
    "collection_name": "<your collection_name>",
    "database_name": "<your database_name>",
    "data_source":"<Source of your datset>",
    "cleaner":"<whether applied cleaner yes/no >"
}
wrt_raw_data = ai.write_raw_data(data_layer, raw_data, date_fields = [])
```
Once raw data is stored, you can run pipelines to transform the data. This code instructs the data store on how to refine the output of raw data into something that can be used to train a machine-learning model. Please refer to the syntax of [MongDB pipelines](https://docs.mongodb.com/manual/core/aggregation-pipeline/) for the details of how to write a pipeline. Below is an example of creating and executing a pipeline.
```python
pipeline = [
        {
            '$group':{
                '_id': {
                    "funding_source":"$funding_source",
                    "request_type":"$request_type",
                    "department_name":"$department_name",
                    "replacement_body_style":"$replacement_body_style",
                    "equipment_class":"$equipment_class",
                    "replacement_make":"$replacement_make",
                    "replacement_model":"$replacement_model",
                    "procurement_plan":"$procurement_plan"
                    },
                "avg_est_unit_cost":{"$avg":"$est_unit_cost"},
                "avg_est_unit_cost_error":{"$avg":{ "$subtract": [ "$est_unit_cost", "$actual_unit_cost" ] }}
            }
        }
]

df = ai.access_data_from_pipeline(wrt_raw_data, pipeline) #refined data will be stored in pandas dataframe.
```

### Run AI Experiments

Use the DXC AI Starter to build and test algorithms. This code executes an experiment by running run_experiment() on an experiment design.

```python
experiment_design = {
    #model options include ['tpot_regression()', 'tpot_classification()', 'timeseries']
    "model": ai.tpot_regression(),
    "labels": df.avg_est_unit_cost_error,
    "data": df,
    #Tell the model which column is 'output'
    #Also note columns that aren't purely numerical
    #Examples include ['nlp', 'date', 'categorical', 'ignore']
    "meta_data": {
      "avg_est_unit_cost_error": "output",
      "_id.funding_source": "categorical",
      "_id.department_name": "categorical",
      "_id.replacement_body_style": "categorical",
      "_id.replacement_make": "categorical",
      "_id.replacement_model": "categorical",
      "_id.procurement_plan": "categorical"
  }
}

trained_model = ai.run_experiment(experiment_design, verbose = False, max_time_mins = 5, max_eval_time_mins = 0.04, config_dict = None, warm_start = False, export_pipeline = True, scoring = None)
```
 [Click here](https://dxc-technology.github.io/DXC-Industrialized-AI-Starter/experiment/) for details about run AI experiments.

### Publish Microservice

The DXC AI Starter library makes it easy to publish your models as working microservices. By default, the DXC AI Starter library uses  free tier of [Algorithmia](https://algorithmia.com/signup) to publish models as microservices. You must create an [Algorithmia](https://algorithmia.com/signup)  account to use. Below is the example for publishing a microservice. 
```python
#trained_model is the output of run_experiment() function
microservice_design = {
    "microservice_name": "<Name of your microservice>",
    "microservice_description": "<Brief description about your microservice>",
    "execution_environment_username": "<Algorithmia username>",
    "api_key": "<your api_key>",
    "api_namespace": "<your api namespace>",   
    "model_path":"<your model_path>"
}

#publish the micro service and display the url of the api
api_url = ai.publish_microservice(microservice_design, trained_model)
print("api url: " + api_url)
```
