Abstract: Embodiments described herein provide a large language model (LLM) based AI agent that adopts Monte-Carlo Tree Search (MCTS) to execute a task. The LLM is prompted with a task description and it responds with its first attempted list of actions. Based on the success or failure of the first attempt, the LLM is prompted with an updated prompt which includes feedback from the first attempt based on a determined reward. The prompt may include a relative “score” for each action taken at each step. A numeric score may be mapped to a set of pre-defined text labels, such as “high” or “low” value putting the score in a form more suited for an LLM prompt. In this way, the LLM is iteratively given prompts which are updated with the scores from each action taken at each previous iterations so that it traverses different paths on the tree in each iteration.

The system extracts fiber connections of the whole brain from diffusion magnetic resonance data, and fiber bundle pathways extracts through self-defined fiber bundle pathways or based on brain fiber bundle templates. A selected fiber bundle pathway is projected on a fiber connection result of the whole brain and finely segmented.

These imaging indexes are configured to classify the disease group and the healthy group by a machine learning method, and which nodes on which fiber bundle pathways have abnormal changes with different diseases can be precisely located.

Abstract: Techniques for data storage involve selecting a target Redundant Array of Independent Disks (RAID) from a plurality of RAIDs in a storage resource pool. Such techniques further involve determining a local neighbor matrix of the target RAID based on the target RAID, wherein the local neighbor matrix indicates distribution of a plurality of storage extents of a plurality of RAID extents of the target RAID on the storage resource pool. Such techniques further involve performing a resource reallocating operation on the storage resource pool based on the local neighbor matrix. Accordingly, a local neighbor matrix can be calculated at the granularity of an individual RAID, and the local neighbor matrix can be applied to balance a local neighboring relationship, so as to ensure overall balance of the neighbor matrix of the entire storage resource pool and improve IO performance.
