An apparatus for performing continuous actions includes a memory storing instructions, and a processor configured to execute the instructions to obtain a first action of an agent, based on a current state of the agent, using a cross-entropy guided policy (CGP) neural network, and control to perform the obtained first action. The CGP neural network is trained using a cross-entropy method (CEM) policy neural network for obtaining a second action of the agent based on an input state of the agent, and the CEM policy neural network is trained using a CEM and trained separately from the training of the CGP neural network.

Disclosed are a procedure and system for live monitoring of staining quality and heavy metal diffusion during electron microscopy preparation protocols for biological samples. The disclosed approach employs x-rays via, e.g., a commercially available micro-CT device, to observe and measure the diffusion and distribution of the heavy metals during conventional biological sample staining procedures for electron microscopy. This allows one to observe and check the quality and homogeneity of the staining without damaging or destroying the sample.

An apparatus for estimating a trajectory of a tool may include: a memory storing instructions; and a processor configured to execute the instructions to: receive a task to be performed by the tool on a target object; receive a grayscale image and a depth image of the target object; and estimate a tool trajectory for performing the task, from the grayscale image and the depth image, via a pixels-to-plans neural network that is trained based on a labeled tool trajectory that is generated from a point cloud model of the target object.
