Using Convolutional Neural Networks and TensorFlow for Image Classification

At the recent NYC TensorFlow meetup, it was discussed how to train an image classifier with TensorFlow. From this blog post, you will learn about the challenges of image classification / search and how to address them with convolutional neural networks.

 

Training an image classifier with TensorFlow

In his session, Scott Thompson of KONTOR talked about:

  • image classification
  • visual search across the Gilt catalog
  • and how convolutional neural networks can enhance the process

When setting up image features (edge detection, color histogram, pixel segmentation, etc.) for classification or search, the job is mostly manual and takes time. According to Scott, convolutional neural networks provide a black box to construct image features. He also outlined some advantages of using a pre-trained model:

  • it’s faster (as it’s pre-trained already)
  • it’s cheaper (no need for GPU farm)
  • it generalizes (avoids overfitting)
