SMQTK v0.5.0 Release Notes¶
This is a minor release that provides minor updates and fixes as well as a new Classifier implementation, new parameters for some existing algorithms and added scripts that were the result of a recent hackathon.
The new classifier implementation, the IndexLabelClassifier
, was created
for the situation where the resultant vector from DescriptorGenerator is
actually classification probabilities. An example where this may be the case
is when a CNN model and configuration for the Caffe implementation yields a
class probability (or Softmax) layer.
The specific scripts added from the hackathon are related to classifying entities based on associated image content.
Updates / New Features since v0.4.0¶
Classifier
- Added classifier that applies a list of text labels from file to vector from descriptor as if it were the classification confidence values.
Descriptor Generators
- Added
input_scale
pass-through option in the Caffe wrapper implementation.- Added default descriptor factory to yield in-memory descriptors unless otherwise instructed.
Descriptor Index
- Added warning logging message when PostgreSQL implementation file fails to import the required python module.
libSVM
- Tweaked some default parameters in grid.py
LSH Functors
- Added descriptor normalization option to ITQ functor class.
Scripts
- Added new output features to classifier model validation script: confusion matrix and ROC/PR confidence interval.
- Moved async batch computation scripts for descriptors, hash codes and classifications to
bin/
.- Added script to transform a descriptor index (or part of one) into the file format that libSVM likes:
descriptors_to_svmtrainfile.py
- Added script to distort a given image in multiple configurable ways including cropping and brightness/contrast transformations.
- Added custom scripts resulting from MEMEX April 2016 hackathon.
- Changed MEMEX update script to collect source ES entries based on crawl time instead of insertion time.
Utilities
- Added async functionality to kernel building functions
Fixes since v0.4.0¶
CMake
- Removed
SMQTK_FIRST_PASS_COMPLETE
stuff in root CMakeLists.txt
Scripts
- Changed
createFileIngest.py
so that all specified data elements are added to the configured data set at the same time instead of many additions.
