  • This weight adjustment process of each layer of signal forward propagation and error back propagation is carried out repeatedly.
  • the process of continuously adjusting the weights is also the learning and training process of the network. This process has been carried out until the error of the network output is reduced to an acceptable level, or until the preset number of learning times.

下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的定位方法及通信设备进行详细地说明。
下面首先对本申请实施例涉及的人工智能(Artificial Intelligence,AI)网络模型进行说明。
人工智能网络模型目前在各个领域获得了广泛的应用。人工智能网络模型有多种实现方式,例如神经网络、决策树、支持向量机、贝叶斯分类器等。本申请以神经网络为例进行说明,但是并不限定上述其它人工智能网络模型的应用。
一个神经网络的示意图如图2所示。其中,神经网络由神经元组成,神经元如图3所示。其中a1,a2,…aK为输入,w为权值(乘性系数),b为偏置(加性系数),σ(.)为激活函数。常见的激活函数包括Sigmoid、tanh、线性整流函数,修正线性单元(Rectified Linear Unit,ReLU)等。
神经网络的参数通过优化算法进行优化。优化算法就是一种能够帮我们最小化或者最大化目标函数(有时候也叫损失函数)的一类算法。而目标函数往往是模型参数和数据的数学组合。例如给定数据X和其对应的标签Y(即真实值),我们构建一个神经网络模型f(.),有了模型后,根据输入X就可以得到预测输出f(x),并且可以计算出预测值和真实值之间的差距(f(x)-Y),这个就是损失函数。我们的目的是找到合适的w,b使上述的损失函数的值达到最小,损失值越小,则说明我们的模型越接近于真实情况。
目前常见的优化算法,基本都是基于误差反向传播(error Back Propagation,BP)算法。BP算法的基本思想是,学习过程由信号的正向传播与误差的反向传播两个过程组成。正向传播时,输入样本从输入层传入,经各隐层逐层处理后,传向输出层。若输出层的实际输出与期望的输出不符,则转入误差的反向传播阶段。误差反传是将输出误差以某种形式通过隐层向输入层逐层反传,并将误差分摊给各层的所有单元,从而获得各层单元的误 差信号,此误差信号即作为修正各单元权值的依据。这种信号正向传播与误差反向传播的各层权值调整过程,是周而复始地进行的。权值不断调整的过程,也就是网络的学习训练过程。此过程一直进行到网络输出的误差减少到可接受的程度,或进行到预先设定的学习次数为止。
常见的优化算法有梯度下降(Gradient Descent)、随机梯度下降(Stochastic Gradient Descent,SGD)、小批量梯度下降(mini-batch gradient descent)、动量法(Momentum)、Nesterov(发明者的名字,具体为带动量的随机梯度下降)、自适应梯度下降(ADAptive GRADient descent,Adagrad)、Adadelta、均方根误差降速(Root Mean Square prop,RMSprop)、自适应动量估计(Adaptive Moment Estimation,Adam)等。
这些优化算法在误差反向传播时,都是根据损失函数得到的误差/损失,对当前神经元求导数/偏导,加上学习速率、之前的梯度/导数/偏导等影响,得到梯度,将梯度传给上一层。
为解决现有直接基于定位信号测量结果进行定位的方法存在误差,无法满足需求的问题,请参考图4A,本申请实施例提供一种定位方法,包括:
