在这些地方,算法的作用既是在探索新信息,同时也是在利用已有的信息,人们开始关注探索与利用算法(Explore as Exploit Algorithm)这一概念。 1. 探索与利用算法的定义 探索与利用算法是指在面对未知信息时,决策者需要权衡选择进一步探索新信息和利用已有信息之间的权衡。在这一过程中,探索意味着寻找新的、未知的信息,而利用意味着利用已有的信息来获得
To provide my perspective on this, I wanted to share my own career journey and how I specifically leveraged an explore & exploit algorithm at every turn of my career to ultimately find my dream job. Bear with me for a minute here, because I'm going to start by taking a detour and ...
We present a new model-based algorithm for reinforcement learning (RL) which consists of explicit exploration and exploitation phases, and is applicable in large or infinite state spaces. The algorithm maintains a set of dynamics models consistent with current experience and explores by finding ...

When making decisions, should one exploit known good options or explore potentially better alternatives? Exploration of spatially unstructured options depends on the neocortex, striatum, and amygdala. In natural environments, however, better options ofte
This algorithm has performed better than alternatives in simulated and real fMRI data, and it is reasonably robust to variations in the timing of neural events and the sampling frequency of the scan97. Within our anatomical mask of the bilateral hippocampus, we deconvolved the BOLD activity for ...
the big metallic asteroid that is about to be visited by its own dedicated probe. Data from that probe will help inform the first iteration of AETHER's learning algorithm, and the input the sensors provide from its visit will update it before its next step - Themis. That asteroid, thoug...
(NLP) algorithm, termed affectr (https://github.com/markallenthornton/affectr), to decode mental state location in 3D space based on the words participants chose to say during the conversation (Supplementary Methods). To test whether there is internal consistency between the neural and mental ...
Then, a novel exploit–explore balanced stochastic natural gradient optimization algorithm is proposed to efficiently explore the search space. Specifically, there are two sequential stages in YOCO-BERT. We decouple the compression process into a “super mode” training process, which does the core ...
