This paper articulates a Dual Lottery Ticket Hypothesis (DLTH) as a dual format of original Lottery Ticket Hypothesis (LTH). Correspondingly, a simple regularization based sparse network training strategy, Random Sparse Network Transformation (RST), is proposed to validate DLTH and enhance sparse network training.

Step 1: Set up environment

• python=3.6
• Install libraries by pip install -r requirements.txt.

Setp 2: Running
