What

This is open-source code that lets you generate short unique identifiers from numbers (within Postgres DB). These IDs are URL-safe, can encode several numbers, and do not contain common profanity words.

This is what they look like:

    Return ranked phrases using MMR. Cosine similarity is used as similarity measure.

    :param phrases: list of candidate phrases
    :param embedding_matrix: matrix having index as phrases and values as vector
    :param lambda_constant: 0.5 to balance diversity and accuracy. if lambda_constant is high, then higher accuracy. If lambda_constant is low then high diversity.
    :param threshold_terms: number of terms to include in result set

ResNet-101 in Keras

This is an Keras implementation of ResNet-101 with ImageNet pre-trained weights. I converted the weights from Caffe provided by the authors of the paper. The implementation supports both Theano and TensorFlow backends. Just in case you are curious about how the conversion is done, you can visit my blog post for more details.
