Description: LLE（Locally Linear Embedding）算法，即局部线性嵌入算法。该算法是针对非线性信号特征矢量维数的优化方法，这种维数优化并不是仅仅在数量上简单的约简，而是在保持原始数据性质不变的情况下，将高维空间的信号映射到低维空间上，即特征值的二次提取-LLE (Locally Linear Embedding) algorithm, local linear embedding algorithm. The algorithm is a method for optimizing nonlinear signal feature vector dimension, this dimension optimization is not just a simple reduction in the number, but the nature of the original data remain under the same circumstances, would signal a high-dimensional space mapped onto the low dimensional space, i.e., the second characteristic value extraction Platform: |

Description: Isomap是一种非线性降维方法。又是一种广泛使用的低维嵌入的方法。[ 1 ] Isomap用于计算准等距，低维嵌入的一组高维数据点。该算法提供了一个简单的方法，用于估计基于一个粗略的估计，每个数据点的邻居流形上的数据流形的内在几何。Isomap是高效和一般适用于范围广泛的数据源和维度。-Isomap is a Nonlinear dimensionality reduction method. And is also one of several widely used low-dimensional embedding methods.[1] Isomap is used for computing a quasi-isometric, low-dimensional embedding of a set of high-dimensional data points. The algorithm provides a simple method for estimating the intrinsic geometry of a data manifold based on a rough estimate of each data point’s neighbors on the manifold. Isomap is highly efficient and generally applicable to a broad range of data sources and dimensionalities. Platform: |

Description: The aim of the present work is to develop a new
Convergecast routing technique which allows to connect many
source nodes to a single sink node via a wireless sensor network
(WSN). The synthesized method overcame the problem of energy
consumption resulting the repetition of the course of the
edges during a transmission period. The proposed technique,
based on intelligent routing algorithm to transmit the collected
data to the base station, ensured a reduction of the routing paths
length. This new approach was applied to a WSN, designed to
control the temperature and volume of propane and butane in
the tanks of the British Gas Group, for minimizing the energy
consumed and increasing the life cycle of the network.
Index Terms—Convergecast routing technique,Wireless Sensor
Network WSN, Reduction of routing paths length, Minimization
of energy consumption, Elongation of the life cycle.-The aim of the present work is to develop a new
