  • Using Data Augmentations in Keras

    When I did the article on Using Bottleneck Features for Multi-Class Classification in Keras and TensorFlow, a few of you asked about using data augmentation in the model. So, I decided to do few articles experimenting various data augmentations on a bottleneck model. As a start, here’s a quick tutorial explaining what data augmentation is, and…

  • Using Bottleneck Features for Multi-Class Classification in Keras and TensorFlow

    Training an Image Classification model – even with Deep Learning – is not an easy task. In order to get sufficient accuracy, without overfitting requires a lot of training data. If you try to train a deep learning model from scratch, and hope build a classification system with similar level of capability of an ImageNet-level…

  • Stepping into audio classification – Getting started with PyAudio

    I’ve had an idea to attempt to train a deep learning model that can classify different audio noises. Having a system that can accurately identify different sounds would have implications in many fields, from medical diagnostics to echo locations systems, among others. I wouldn’t expect building such a system would be an easy task. But,…
