In this page, we will present to you different Rescale job examples for four different applications. Click on the Import Job Setup button to clone an example job into your account, which you can then submit. Click on the Get Job Results button to review the full setup and results of a completed example.

Supported Frameworks and Applications
Keras is a high-level neural network Python framework built on top of TensorFlow, CNTK, and Theano. It supports higher-order primitives specifically for convolutional and recurrent neural networks.
Here is an example of training a classification model on the classic MNIST handwritten digit dataset. We will train a simple multi-layer perceptron model using this input training script.
PyTorch is the Python port of the Torch deep learning framework. PyTorch is known for great support for building dynamic neural networks and doing reinforcement learning.
Super Resolution Example
The first example is training and then using a model to perform “super-resolution” to scale up an image while minimizing noise.

LSTM DOE Example
So far examples have focused on training a single model for a task with a set of parameters selected by the user building the model. The example here is now a Design of Experiments (DOE)DOE stands for "Design of Experiments." It is a statistical ... More which is a sensitivity analysis for one or more parameters. Here is an example using the Rescale DOE framework to build many models, randomly sampling hyper-parameters that define the model. This case builds a LSTM model to perform word-level modelingModeling is the creation of a mathematical or conceptual rep... More.
In this case, we are doing a Monte Carlo sampling of the following LSTM model parameters:
The embed _size and n_hidden parameters impact how many nodes are in the network. The dropout parameter is used to control overfitting to input data. Finally, batch_size determines how many examples we train one at a time.
