A repository of PyBullet utility functions for robotic motion planning

pybullet-planning (ss-pybullet) A repository of PyBullet utility functions for robotic motion planning, manipulation planning, and task and motion planning (TAMP). This repository was originally developed for the PDDLStream (previously named STRIPStream) approach to TAMP. With the help of Yijiang Huang, a stable and documented fork of ss-pybullet named pybullet_planning is available through PyPI. However, new features will continue to be introduced first through ss-pybullet. Installation Install PyBullet on OS X or Linux using: $ pip install numpy pybullet $ git […]

A Guide to Feature Engineering in NLP

Overview Feature engineering in NLP is understanding the context of the text. In this blog, we will look at some of the common feature engineering in NLP. We will compare the results of a classification task with and without doing feature engineering   Table of Content Introduction NLP task overview List of features with code Implementation Results comparison with and without doing feature engineering Conclusion Introduction   “If 80 percent of our work is data preparation, then ensuring data quality […]

Issue #126 – Learning Feature Weights for Denoising Parallel Corpora

15 Apr21 Issue #126 – Learning Feature Weights for Denoising Parallel Corpora Author: Dr. Patrik Lambert, Senior Machine Translation Scientist @ Iconic Introduction Large web-crawled parallel corpora constitute a very useful source of data to improve neural machine translation (NMT) engines. However, their effectiveness is reduced by the large amount of noise they usually contain. As early as in issue #2 of this series, we pointed out that NMT is particularly sensitive to noise in the training data. In issue […]

Pixel Art Reverse Image Search for OpenGameArt

PixelArtSearch Pixel art search engine for opengameart. ## What data do you need on each image to create a reverse image search? I used [VGG16 feature extraction](https://towardsdatascience.com/extract-features-visualize-filters-and-feature-maps-in-vgg16-and-vgg19-cnn-models-d2da6333edd0) in [my script for this](https://github.com/emnh/PixelArtSearch/blob/master/scripts/featureVectors.py). See the article for more information, but in essence it’s 4096 32-bit floating point numbers for each image, which describe various features of the image, say for instance in a very simplified way how many stripes or squares it has or how green it is. But these features […]
