this mug is a cat - YOLOv2

Regular price $22.00

This mug looks like a mug to a human, but has been painted to convince object detection systems that it's a cat. Buy one and you can look like you have a cat on your desk next to the keyboard where your actual cat is taking a nap.

Adversarial patches don't always transfer well between models. This patch was specifically designed to be effective against YOLOv2.

• Ceramic
• 11 oz mug dimensions: 3.85″ (9.8 cm) in height, 3.35″ (8.5 cm) in diameter
• 15 oz mug dimensions: 4.7″ (12 cm) in height, 3.35″ (8.5 cm) in diameter
• Dishwasher and microwave safe

• Ignores laser pointers and scratchy noises

This adversarial designs mug uses a targeted adversarial patch that maximizes the class probability for cat in the bounding box for the mug. The patch is trained with dynamic spline warping to account for the curvature of the mug's surface.
