Abstract: The invention relates to a hair styling device, and in particular to a hair straightener. The hair styling device (10; 210) has a first arm (12; 212) and a second arm (14; 214), the first and second arms being moveable relative to one another between a closed or operative condition and an open or inoperative condition. The first member (12; 212) has a first heating panel (16; 116; 216) and the second member (14; 214) has a second heating panel (18; 118; 218). The heating panels (16, 18; 116, 118; 216, 218) are corrugated to increase the length of the path the hair must take between the heating panels. The first and second heating panels are spaced apart in the operative condition so as not to press or clamp the hair therebetween.

Abstract: An agent trained using reinforcement learning (RL) can be used to determine a structure for a complex tensor network. The agent makes incremental changes to a tensor network according to a policy model, where parameters of the policy model were trained using RL. The agent may use a cost function to assess the changes, e.g., to determine whether or not to keep a particular modification. In some cases, tensor networks determined using the RL agent can be used to train a model that can more efficiently select a structure for a complex tensor network.
