Deep quantile regression for growth and maturation reaction norms
Methods in Ecology and Evolution, Volume 17, Issue 1, Page 111-124, January 2026.Abstract Understanding species' growth and maturation responses to anthropogenic and environmental pressures is crucial for tracking demographic shifts, phenotypic change and ensuring population sustainability. Traditional regression methods often focus on modelling the conditional mean of life‐history traits, potentially overlooking heterogeneity in ...

The research on multi-source information fusion method in Fire Monitoring System [PDF]
, 2015 火灾是威胁人民生命安全和社会发展最为经常、普遍的灾害之一。近年来，室内火灾发生率在全球所发生的火灾中占比约百分之八十以上。国际消防技术委员会对这个现象非常的重视，希望各国的相关部门可以对此采取有效的措施。各国为此都采用了比较有效的方法，也就是利用信息科技技术手段对室内火灾环境进行监测预防，使得火灾得到有效防控。 生活中普遍的火灾监测系统中多采用烟雾传感器监测单一的环境参量，并简单地通过阈值法来判断火灾情况。这难免会因为传感器失灵，自然环境影响等不可抗拒的因素造成系统误报或是漏报的概率变大 ...

Design and Implementation of Game AI Decision Engine Based on Neural Networks and Finite State Machine [PDF]
, 2016 计算机硬件的发展以及越来越多的复杂的大型游戏发布，人工智能成为游戏中不可或缺的一部分，游戏中引入人工智能逐渐成为了一款游戏吸引玩家的有效手段之一。人工智能在游戏中能增加玩家的挑战性、创造更真实的虚拟世界、增加游戏的可玩性、辅助其他功能。 人工智能在游戏上的实现，有两种不同的方式。一种是采用传统的编程技术，使系统呈现智能的效果，而不考虑所用方法是否与人或生物机体所用的方法相似。这种方法称为工程学方法，它的编程方式虽然简单，智能效果显著，可是算法和程序一旦固定下来，智能就很难再进一步提高。另一种是模拟法 ...

Design and Implementation of Educational Administration Management System Based on Data Mining Technology [PDF]
, 2015 人们通过数据挖掘技术发现了数据的另一面，对它的认识、分析和使用都到达了另一个高度。数据挖掘技术普遍的使用在各个领域，特别是在金融、互联网等领域高度应用。教育领域具有海量的数据，但是基于数据挖掘的应用基本没有。目前，在各个高校，广泛使用的教务管理系统的主要功能是处理日常事务。在处理日常事务的过程中，会产生大量的数据，这些数据仅仅得到了存储，并没有发挥其内在的功能，即隐藏在数据中的有效信息没有被发现。具体而言，在大批数据中，数据挖掘技术可以发掘影响教学质量和学生成绩的主要因素，并基于主要因素 ...

Improvement of the Hopfield Neural Network and Transfer-matrix calculation of positional distribution in the 2-dimensional semiflexible polymer [PDF]
, 2006 摘要本文主要分为两个部分，第一部分为用蒙特卡罗变异优化选择规则优化Hopfield神经网络，第二部分为转移矩阵在二维半柔软聚合物研究中的应用。第一部分研究表明蒙特卡罗变异优化选择规则可以用来优化神经网络的性能。在第一部分我们以Hopfield网络为例，运用蒙特卡罗变异优化选择规则在保持网络的整体结构基本不变的情况下，优化Hopfield神经网络的动力学特性，提高网络的存储功能和存储质量。在优化后的网络中，每个记忆模式都被严格设计成网络的不动点吸引子，从而每个模式都能够被精确联想 ...
