For example, if after training our network we have a weight: 1) which mean is close to zero and 2) we are very sure about it (this is, uncertainty is very low) we can prune the neuron associated to it (easy peasy!). Pruning a model is usually important in real-world applications....
If we increase the number of layers in a neural network to make it deeper, it increases the complexity of the network and allows us to model functions that are more complicated. However, the number of weights and biases will exponentially increase. As a matter of fact, learning such ...

PyNN is an application programming interface (API) for describing and simulating neuronal network models in the Python programming language. Numerical solution of the model equations is performed by a “backend” simulator, which as of PyNN version 0.7 can be any of NEURON (Hines and Carnevale 199...
sklearn.neural_network 是 scikit-learn 库中的一个模块,提供了创建和训练神经网络模型的工具。scikit-learn 是一个广泛使用的 Python 机器学习库,以其简洁性和高效性著称。该库的设计理念是通过简洁的接口和高效的实现,使用户能够快速构建和应用机器学习模型。neural_network 模块特别实现了多层感知器(MLP),这是一...

Neural Network之模型复杂度主要取决于优化参数个数与参数变化范围. 优化参数个数可手动调节, 参数变化范围可通过正则化技术加以限制. 正则化技术之含义是: 引入额外的条件, 对function space进行适当的约束. 本文借助pytorch前向计算与反向传播特性, 以正则化技术之weight decay(l2范数)为例, 简要演示正则化对Neural...
