smqtk-core 0.18.2

Python toolkit for pluggable algorithms and data structures for multimedia-based machine learning.

SMQTK - Core

A light-weight, non-intrusive framework for developing interfaces that have built-in implementation discovery and factory construction from a simple configuration structure.

While anything may make use of this library, this was originally developed as a foundation for a suite of packages that predominantly support AI and Machine Learning use-cases:

• Scalable data structure interfaces and implementations, with a focus on those relevant for machine learning like descriptors, classifications, and object detections.

• Interfaces and implementations of machine learning algorithms with a focus on media-based functionality.

Libraries

Some above-mentioned packages supporting AI/ML topics include the following:

• SMQTK-Dataprovider provides abstractions around data storage and retrieval.

• SMQTK-Image-IO provides interfaces and implementations around image reading and writing using abstractions defined in SMQTK-Dataprovider.

• SMQTK-Descriptors provides algorithms and data structures around computing descriptor vectors from different kinds of input data.

• SMQTK-Classifier provides interfaces and implementations around black-box classification.

• SMQTK-Detection provides interfaces and support for black-box object detection.

• SMQTK-Indexing provides interfaces and implementations for efficient, large-scale indexing of descriptor vectors. The sources of such descriptor vectors may come from a multitude of sources, such as hours of video archives. Some provided implementation plugins include Locality-sensitive Hashing (LSH) and FAIR's FAISS library.

• SMQTK-Relevancy provides interfaces and implementations for ranking datasets using human-in-the-loop feedback. This is a primary component for Interactive Query Refinement (IQR) systems that makes use of human feedback.

• SMQTK-IQR provides classes and utilities to perform the Interactive Query Refinement (IQR) process. This package also includes a web API exposing the use of these tools as well as an example web UI service to demonstrate the capability. These services are additionally containerized to provide some portability of these services.

These packages are related as follows:

This looks a lot like KWIVER! Why use this instead?

KWIVER is another open source package that similarly holds modularity, plugins and configurability at its core.

The SMQTK-* suite of functionality exists separately from KWIVER for a few reasons (for now):

• History
  • The origins of KWIVER and SMQTK were initiated at roughly the same time and were never resolved into the same thing because...
• Language
  • KWIVER has historically been predominantly C++ while SMQTK-* is (mostly) pure python. (see note below)
• Configuration UX
  • SMQTK takes an "add on" approach to configurability: concrete implementations have parameterized constructors and should be usable after construction like a "normal" object. Configuration semantics are derived from introspection of, and explicitly related to, the constructor. KWIVER takes an alternative approach where construction is generally empty and configuration setting is a required separate step via a custom object (ConfigBlock).
• Pythonic Plugin Support
  • Plugins are exposed via standard package entrypoints.

If I'm using python, does that mean that SMQTK is always the better choice?

At this point, not necessarily. While this used to be true for a number of years due to SMQTK being the toolkit with python support. This is becoming more blurry KWIVER's continuously improving python binding support.
