SubNet

Keras implementation of SubNetwork

Results

Compare accuracy and number of parameters

The following results can be reproduced with command:

python main.py --dataset MNIST --subset 1 4
python main.py --dataset MNIST --subset 0 2 6
python main.py --dataset MNIST --subset 0 4 6 7
python main.py --dataset MNIST --subset 0 1 2 3 4 5 6 7 8 9
python main.py --dataset FashionMNIST --subset 5 7 9
python main.py --dataset FashionMNIST --subset 0 1 2 3 4 5 6 7 8 9

Average number of nodes according to number of subset elements

The following results can be reproduced with command:

python main.py --dataset MNIST --subset 0 1 2 3 4 5 6 7 8 9 --meanNodes True
python main.py --dataset FashionMNIST --subset 0 1 2 3 4 5 6 7 8 9 --meanNodes True

Average number of Nodes

X-axis: Average number of nodes, Y-aixs: number of subset elements

Usage

Prerequisites

1. Keras
2. Python packages: numpy

Command

python main.py --dataset <choose dataset> --subset <subset of total categories>

Example: python main.py --dataset MNIST --subset 0 1 2 3

Arguments

Required:

• --dataset: Choose datset. Option: MNIST or FasionMNIST
• --subset: Subset elements of total categories. example: --subset 0 1 2

Optional:

• --meanNodes: Whether or not to print the average number of nodes. type: bool, Default: False
