Deep Learning with Databricks

Description

This course begins by covering the basics of neural networks and the tensorflow.keras API. We will focus on how to leverage Spark to scale our models, including distributed training, hyperparameter tuning, and inference, while leveraging MLflow to track, version, and manage these models. We will deep dive into distributed deep learning, including hands-on examples to compare and contrast various techniques for distributed data preparation, including Petastorm and TFRecord, as well as distributed training techniques such as Horovod and spark-tensorflow-distributor. To better understand the model’s predictions, you will apply model interpretability libraries. Further, you will learn the concepts behind Convolutional Neural Networks (CNNs) and transfer learning, and apply them to solve image classification tasks. We will wrap up the course by covering Recurrent Neural Networks (RNNs) and attention-based models for natural language processing (NLP) applications.
