aisquared 0.3.13

Utilities for interacting with the AI Squared Technology Stack

AISquared

This package contains utilities to interact with the AI Squared technology stack, particularly with developing and deploying models to the AI Squared Platform or other applications developed through the AI Squared JavaScript SDK.

Installation

This package is available through Pypi and can be installed by running the following command:

pip install aisquared

Alternatively, the latest version of the software can be installed directly from GitHub using the following command

pip install git+https://github.com/AISquaredInc/aisquared

Capabilities

This package is currently in a state of constant development, so it is likely that breaking changes can be made at any time. We will work diligently to document changes and make stable releases in the future.

The aisquared package currently contains five subpackages, the aisquared.config package, the aisquared.base subpackage, the aisquared.logging subpackage, the aisquared.serving subpackage, and the aisquared.platform package. The config package holds objects for building the configuration files that need to be included with converted model files for use within the AI Squared Extension. The contents of the config subpackage contain both pre- and postprocessing steps as well as harvesting, analytic, rendering, and feedback objects to use with the model. The following will explain the functionality of the config package:

aisquared.config

The aisquared.config subpackage contains the following objects:

• ModelConfiguration
  • The ModelConfiguration object is the final object to be used to create the configuration file. It takes as input a list of harvesting steps, list of preprocessing steps, a list of analytics, a list of postprocessing steps, a list of rendering steps, an optional MLFlow URI, an optional MLFlow user, and an optional MLFlow token
• GraphConfiguration
  • The `GraphConfiguration object is another method for creating configuration files. Instead of taking a predefined set of steps, it allows the developer to add steps to create a directed acyclic graph

aisquared.config.harvesting

The aisquared.config.harvesting subpackage contains the following objects:

• ImageHarvester
  • The ImageHarvester class indicates the harvesting of images within the DOM to perform prediction on
• TextHarvester
  • The TextHarvester class indicates the harvesting of text within the DOM to perform prediction on

  • The InputHarvester class configures harvesting of different kinds of user-defined inputs
• QueryParameterHarvester
  • The QueryParameterHarvester class configures harvesting based on query parameters

aisquared.config.preprocessing

The aisquared.config.preprocessing subpackage contains the following objects:

• ImagePreprocessor
  • The ImagePreprocessor class takes in preprocessing steps (defined below) which define preprocessing steps for images.

aisquared.config.postprocessing

The aisquared.config.postprocessing subpackage contains the following objects:

• Regression
  • The Regression object is a postprocessing class for models which perform regression. Since it is common to train regression models by scaling regression outputs to values between 0 and 1, this class is designed to convert output values between 0 and 1 to their original values, corresponding to min and max when the class is instantiated.
• BinaryClassification
  • The BinaryClassification object is a postprocessing class for models which perform binary classification. The class is instantiated with a label map and a cutoff value used to identify when the positive class (class 1) is identified.
• MulticlassClassification
  • The MulticlassClassification object is a postprocessing class for models which perform multiclass classification. The class is instantiated with a label map only.
• ObjectDetection
  • The ObjectDetection object is a postprocessing class for models which perform object detection. The class is instantiated with a label map and a cutoff value for identification.

aisquared.config.rendering

The aisquared.config.rendering subpackage contains the following objects:

• ImageRendering
  • The ImageRendering object is a rendering class for rendering single predictions on images.
• ObjectRendering
  • The ObjectRendering object is a rendering class for rendering object detection predictions on images.

These step objects can then be placed within the TabularPreprocessor, ImagePreprocessor, or TextPreprocessor objects. For the TabularPreprocessor, the ZScore, MinMax, and OneHot Steps are supported. For the ImagePreprocessor, the AddValue, SubtractValue, MultiplyValue, DivideValue, ConvertToColor, and Resize Steps are supported. For the TextPreprocessor, the Tokenize, RemoveCharacters, ConvertToCase, ConvertToVocabulary, and PadSequences Steps are supported

Final Configuration and Model Creation

Once harvesting, preprocessing, analytic, postprocessing, and rendering objects have been created, these objects can then be passed to the aisquared.config.ModelConfiguration class. This class utilizes the objects passed to it to build the entire model configuration automatically.

Once the ModelConfiguration object has been created with the required parameters, the .compile() method can be used to create a file with the .air extension that can be loaded into an application which utilizes the AI Squared JavaScript SDK.

aisquared.base

The aisquared.base subpackage contains base utilities not designed to be directly called by the end user.

aisquared.platform

The aisquared.platform subpackage contains classes and utilities for interacting with the AI Squared Platform. It primarily contains the AISquaredPlatformClient with the following capabilities:

• The ability to securely log in to an instance of the AI Squared Platform
• The ability to check whether the connection is healthy
• The ability to list .air files deployed to the platform
• The ability to retrieve the configuration for a .air file deployed in the platform
• The ability to delete a .air file deployed in the platform

• The ability to list all users in a group in the platform

aisquared.serving (requires installing aisquared[full])

The aisquared.serving subpackage contains utilities for serving models locally or remotely using MLflow or locally using Flask.

aisquared.logging (requires installing aisquared[full])

The aisquared.logging subpackage is powered by MLflow, a powerful open-source platform for the machine learning lifecycle. The logging subpackage inherits nearly all functionality from mlflow, so we highly recommend users refer to the MLflow documentation site for additional information.

In this subpackage, we have additionally added implementations of individual functions to save TensorFlow, Keras, Scikit-Learn, and PyTorch models in a format that can be deployed quickly using MLflow.
