Project Description:

AinShamsFlow (asf) is a Deep Learning Framework built by our Team from Ain Shams University during December 2020 - January 2021.

The Design and Interface is inspired heavily from Keras and TensorFlow.

However, we only implement everything from scratch using only simple libraries such as numpy and matplotlib.

Project Structure:

The Design of all parts can be seen in the following UML Diagram.

This is how the Design Structure should work in our Framework.

You can read more details on our documentation.

Install:

You can install the latest available version as follows:

$ pip install ainshamsflow

Usage:

you start using this project by importing the package as follows:

>>> import ainshamsflow as asf

then you can start creating a model:

>>> model = asf.models.Sequential([
...     asf.layers.Dense(300, activation="relu"),
...     asf.layers.Dense(100, activation="relu"),
...     asf.layers.Dense( 10, activation="softmax")
... ], input_shape=(784,), name="my_model")
>>> model.print_summary()

then compile and train the model:

>>> model.compile(
... 	optimizer=asf.optimizers.SGD(lr=0.01),
... 	loss='sparsecategoricalcrossentropy',
...     metrics=['accuracy']
... )
>>> history = model.fit(X_train, y_train, epochs=100)

finally you can evaluate, predict and show training statistics:

>>> history.show()
>>> model.evaluate(X_valid, y_valid)
>>> y_pred = model.predict(X_test)

A more elaborate example usage can be found in main.py or check out this demo notebook.

Example Usage:

This part can be found in the demo notebook mentioned above.

• Download and Split a dataset (MNIST or CIFAR-10) to training, validation and testing
• Construct an Architecture (LeNet or AlexNet) and make sure all of its components are provided in your framework.
• Train and test the model until a good accuracy is reached (Evaluation Metrics will need to be implemented in the framework also)
• Save the model into a compressed format
