"This notebook shows how to use [Fairlearn (an open source fairness assessment and unfairness mitigation package)](http://fairlearn.github.io) and Azure Machine Learning Studio for a binary classification problem. This example uses the well-known adult census dataset. For the purposes of this notebook, we shall treat this as a loan decision problem. We will pretend that the label indicates whether or not each individual repaid a loan in the past. We will use the data to train a predictor to predict whether previously unseen individuals will repay a loan or not. The assumption is that the model predictions are used to decide whether an individual should be offered a loan. Its purpose is purely illustrative of a workflow including a fairness dashboard - in particular, we do **not** include a full discussion of the detailed issues which arise when considering fairness in machine learning. For such discussions, please [refer to the Fairlearn website](http://fairlearn.github.io/).\n",
|
||||
"\n",
|
||||
"We will apply the [grid search algorithm](https://fairlearn.github.io/api_reference/fairlearn.reductions.html#fairlearn.reductions.GridSearch) from the Fairlearn package using a specific notion of fairness called Demographic Parity. This produces a set of models, and we will view these in a dashboard both locally and in the Azure Machine Learning Studio.\n",

In the ideal case, we would have a predictor at (1,0) - perfectly accurate and without any unfairness under demographic parity (with respect to the protected attribute \"sex\"). The Pareto front represents the closest we can come to this ideal based on our data and choice of estimator. Note the range of the axes - the disparity axis covers more values than the accuracy, so we can reduce disparity substantially for a small loss in accuracy. Finally, we also see that the unmitigated model is towards the top right of the plot, with high accuracy, but worst disparity.\n",

You can launch the "Anaconda Prompt" window by hitting the Start button and typing "Anaconda Prompt". If you don't see the application "Anaconda Prompt", you might not have conda or mini conda installed. In that case, you can install it [here](https://conda.io/miniconda.html)

||||
3. Check that you have conda 4.4.10 or later. You can check the version with the command `conda -V`. If you have a previous version installed, you can update it using the command: `conda update conda`.

## import AutoMLConfig fails after upgrade from before 1.0.76 to 1.0.76 or later
|

There were package changes in automated machine learning version 1.0.76, which require the previous version to be uninstalled before upgrading to the new version.
|
||||
If you have manually upgraded from a version of automated machine learning before 1.0.76 to 1.0.76 or later, you may get the error:
|

`ImportError: cannot import name 'AutoMLConfig'`

## Remote run: DsvmCompute.create fails
|
||||
## KeyError: 'brand' when running AutoML on local compute or Azure Databricks cluster**
|
||||
If a new environment was created after 10 June 2020 using SDK 1.7.0 or lower, training may fail with the above error due to an update in the py-cpuinfo package. (Environments created on or before 10 June 2020 are unaffected, as well as experiments run on remote compute as cached training images are used.) To work around this issue, either of the two following steps can be taken:
|
||||
|
||||
1) Update the SDK version to 1.8.0 or higher (this will also downgrade py-cpuinfo to 5.0.0):
|
||||
`pip install --upgrade azureml-sdk[automl]`
|
||||
|
||||
2) Downgrade the installed version of py-cpuinfo to 5.0.0:
|
||||
`pip install py-cpuinfo==5.0.0`
|
||||
|
||||
## Remote run: DsvmCompute.create fails
|
||||
There are several reasons why the DsvmCompute.create can fail. The reason is usually in the error message but you have to look at the end of the error message for the detailed reason. Some common reasons are:
|
||||
1) `Compute name is invalid, it should start with a letter, be between 2 and 16 character, and only include letters (a-zA-Z), numbers (0-9) and \'-\'.` Note that underscore is not allowed in the name.
|
||||
2) `The requested VM size xxxxx is not available in the current region.` You can select a different region or vm_size.

## Remote run: Iterations show as "Not Responding" in the RunDetails widget.
|
||||
This can be caused by too many concurrent iterations for a remote DSVM. Each concurrent iteration usually takes 100% of a core when it is running. Some iterations can use multiple cores. So, the max_concurrent_iterations setting should always be less than the number of cores of the DSVM.

To resolve this issue, try reducing the value specified for the max_concurrent_iterations setting.

We will create two pipelines, the first one to demonstrate a training dataset that gets updated over time. We leverage time-series capabilities of `TabularDataset` to achieve this. The second pipeline utilizes pipeline `Schedule` to trigger continuous retraining. \n",

# Experimental Notebooks for Automated ML
|
||||
Notebooks listed in this folder are leveraging experimental features. Namespaces or function signitures may change in future SDK releases. The notebooks published here will reflect the latest supported APIs. All of these notebooks can run on a client-only installation of the Automated ML SDK.
|
||||
The client only installation doesn't contain any of the machine learning libraries, such as scikit-learn, xgboost, or tensorflow, making it much faster to install and is less likely to conflict with any packages in an existing environment. However, since the ML libraries are not available locally, models cannot be downloaded and loaded directly in the client. To replace the functionality of having models locally, these notebooks also demonstrate the ModelProxy feature which will allow you to submit a predict/forecast to the training environment.
|
||||
|
||||
<a name="localconda"></a>
|
||||
## Setup using a Local Conda environment
|
||||
|
||||
To run these notebook on your own notebook server, use these installation instructions.
|
||||
The instructions below will install everything you need and then start a Jupyter notebook.
|
||||
If you would like to use a lighter-weight version of the client that does not install all of the machine learning libraries locally, you can leverage the [experimental notebooks.](experimental/README.md)
|
||||
|
||||
### 1. Install mini-conda from [here](https://conda.io/miniconda.html), choose 64-bit Python 3.7 or higher.
|
||||
- **Note**: if you already have conda installed, you can keep using it but it should be version 4.4.10 or later (as shown by: conda -V). If you have a previous version installed, you can update it using the command: conda update conda.
|
||||
There's no need to install mini-conda specifically.
|
||||
|
||||
### 2. Downloading the sample notebooks
|
||||
- Download the sample notebooks from [GitHub](https://github.com/Azure/MachineLearningNotebooks) as zip and extract the contents to a local directory. The automated ML sample notebooks are in the "automated-machine-learning" folder.
|
||||
|
||||
### 3. Setup a new conda environment
|
||||
The **automl_setup_thin_client** script creates a new conda environment, installs the necessary packages, configures the widget and starts a jupyter notebook. It takes the conda environment name as an optional parameter. The default conda environment name is azure_automl_experimental. The exact command depends on the operating system. See the specific sections below for Windows, Mac and Linux. It can take about 10 minutes to execute.
|
||||
|
||||
Packages installed by the **automl_setup** script:
|
||||
<ul><li>python</li><li>nb_conda</li><li>matplotlib</li><li>numpy</li><li>cython</li><li>urllib3</li><li>pandas</li><li>azureml-sdk</li><li>azureml-widgets</li><li>pandas-ml</li></ul>
|
||||

### 4. Running configuration.ipynb
|
||||
- Before running any samples you next need to run the configuration notebook. Click on [configuration](../../configuration.ipynb) notebook
|
||||
- Execute the cells in the notebook to Register Machine Learning Services Resource Provider and create a workspace. (*instructions in notebook*)
|
||||
|
||||
### 5. Running Samples
|
||||
- Please make sure you use the Python [conda env:azure_automl_experimental] kernel when trying the sample Notebooks.
|
||||
- Follow the instructions in the individual notebooks to explore various features in automated ML.
|
||||
|
||||
### 6. Starting jupyter notebook manually
|
||||
To start your Jupyter notebook manually, use:
|
||||
|
||||
```
|
||||
conda activate azure_automl
|
||||
jupyter notebook
|
||||
```
|
||||
|
||||
or on Mac or Linux:
|
||||
|
||||
```
|
||||
source activate azure_automl
|
||||
jupyter notebook
|
||||
```

# Running using python command
|
||||
Jupyter notebook provides a File / Download as / Python (.py) option for saving the notebook as a Python file.
|
||||
You can then run this file using the python command.
|
||||
However, on Windows the file needs to be modified before it can be run.
|
||||
The following condition must be added to the main code in the file:
|
||||
|
||||
if __name__ == "__main__":
|
||||
|
||||
The main code of the file must be indented so that it is under this condition.

This customization can be used in the scenario that the type of the column cannot correctly reflect its purpose. Some numerical columns, for instance, can be treated as Categorical columns which need to be converted to categorical while some can be treated as epoch timestamp which need to be converted to datetime. To tell our SDK to correctly preprocess these columns, a configuration need to be add with the columns and their desired types.\n",

The supported imputing methods for target column are constant and ffill (forward fill). The supported imputing methods for feature columns are mean, median, most frequent, constant and ffill (forward fill). This customization can be used for the scenario that our customers know which imputation methods fit best to the input data. For instance, some datasets use NaN to represent 0 which the correct behavior should impute all the missing value with 0. To achieve this behavior, these columns need to be configured as constant imputation with `fill_value` 0.\n",

One way to mitigate this problem is to fit models for different series in parallel if you have multiple compute cores available.

"In this example we use the scikit-learn's [digit dataset](http://scikit-learn.org/stable/datasets/index.html#optical-recognition-of-handwritten-digits-dataset) to showcase how you can use AutoML for handling missing values in data. We also provide a stopping metric indicating a target for the primary metrics so that AutoML can terminate the run without necessarly going through all the iterations. Finally, if you want to avoid a certain pipeline, we allow you to specify a blacklist of algorithms that AutoML will ignore for this run.\n",

# Introduction
|
||||
SQL Server 2017 or 2019 can call Azure ML automated machine learning to create models trained on data from SQL Server.
|
||||
This uses the sp_execute_external_script stored procedure, which can call Python scripts.
|
||||
SQL Server 2017 and SQL Server 2019 can both run on Windows or Linux.
|
||||
However, this integration is not available for SQL Server 2017 on Linux.
|
||||
|
||||
This folder shows how to setup the integration and has a sample that uses the integration to train and predict based on an energy demand dataset.
|
||||
|
||||
This integration is part of SQL Server and so can be used from any SQL client.
|
||||
These instructions show using it from Azure Data Studio or SQL Server Managment Studio.
|
||||
|
||||
<a name="azuredatastudiosetup"></a>
|
||||
## Setup using Azure Data Studio

## Energy demand example using SQL Server Management Studio
|
||||
|
||||
Once you have completed the setup, you can try the energy demand sample queries.
|
||||
First you need to load the sample data in the database.
|
||||
1. In SQL Server Management Studio, you can right-click the database, select Tasks, then Import Flat file.
|
||||
1. Select the file MachineLearningNotebooks\notebooks\how-to-use-azureml\automated-machine-learning\forecasting-energy-demand\nyc_energy.csv.
|
||||
1. When you get to the column definition page, allow nulls for all columns.
|
||||
|
||||
You can then run the queries in the energy-demand folder:
|
||||
* TrainEnergyDemand.sql runs AutoML, trains multiple models on data and selects the best model.
|
||||
* ForecastEnergyDemand.sql forecasts based on the most recent training run.
|
||||
* GetMetrics.sql returns all the metrics for each model in the most recent training run.

Azure Databricks is a managed Spark offering on Azure and customers already use it for advanced analytics. It provides a collaborative Notebook based environment with CPU or GPU based compute cluster.
|
||||
|
||||
In this section, you will find sample notebooks on how to use Azure Machine Learning SDK with Azure Databricks. You can train a model using Spark MLlib and then deploy the model to ACI/AKS from within Azure Databricks. You can also use Automated ML capability (**public preview**) of Azure ML SDK with Azure Databricks.
|
||||
|
||||
- Customers who use Azure Databricks for advanced analytics can now use the same cluster to run experiments with or without automated machine learning.
|
||||
- You can keep the data within the same cluster.
|
||||
- You can leverage the local worker nodes with autoscale and auto termination capabilities.
|
||||
- You can use multiple cores of your Azure Databricks cluster to perform simultenous training.
|
||||
- You can further tune the model generated by automated machine learning if you chose to.
|
||||
- Every run (including the best run) is available as a pipeline, which you can tune further if needed.
|
||||
- The model trained using Azure Databricks can be registered in Azure ML SDK workspace and then deployed to Azure managed compute (ACI or AKS) using the Azure Machine learning SDK.
|
||||
|
||||
Please follow our [Azure doc](https://docs.microsoft.com/en-us/azure/machine-learning/service/how-to-configure-environment#azure-databricks) to install the sdk in your Azure Databricks cluster before trying any of the sample notebooks.
|
||||
|
||||
**Single file** -
|
||||
The following archive contains all the sample notebooks. You can the run notebooks after importing [DBC](Databricks_AMLSDK_1-4_6.dbc) in your Databricks workspace instead of downloading individually.
|
||||
|
||||
Notebooks 1-4 have to be run sequentially & are related to Income prediction experiment based on this [dataset](https://archive.ics.uci.edu/ml/datasets/adult) and demonstrate how to data prep, train and operationalize a Spark ML model with Azure ML Python SDK from within Azure Databricks.
|
||||
|
||||
Notebook 6 is an Automated ML sample notebook for Classification.
|
||||
|
||||

**Databricks as a Compute Target from AML Pipelines**
|
||||
You can use Azure Databricks as a compute target from [Azure Machine Learning Pipelines](https://docs.microsoft.com/en-us/azure/machine-learning/service/concept-ml-pipelines). Take a look at this notebook for details: [aml-pipelines-use-databricks-as-compute-target.ipynb](https://github.com/Azure/MachineLearningNotebooks/tree/master/how-to-use-azureml/azure-databricks/databricks-as-remote-compute-target/aml-pipelines-use-databricks-as-compute-target.ipynb).
