课程名称:人工智能 #5:使用 Scikit 和 Keras 的多层感知器网络 课程概述:本课程介绍人工神经网络(ANN)或连接主义系统,这些计算系统受到动物大脑生物神经网络的模糊启发。这样的系统通过考虑实例来“学习”执行任务,通常不需要编写任何任务特定的规则。例如,在图像识别中,它们可以通过分析手动标记为“猫”或“非猫”的示例图像,学习识别包含猫的图像,进而识别其他图像中的猫。ANN 基于一组连接的单元或节点,称为人工神经元, loosely 模拟生物大脑中的神经元。每个连接可以传递信号,形成与生物大脑中突触相类似的功能。 在本课程中,您将学习如何使用 Scikit learn 和 Keras 库以及 Python 构建多层感知器(MLP)神经网络。您将学习如何使用 MLP 分类器对数据集进行分类,找出正确的类别。接下来,您将深入学习如何在 Keras 环境中使用神经网络进行时间序列模型的预测。在第一个部分,您将学习如何使用 Python 和 sklearn MLP 分类器预测不同数据集的输出,包括逻辑门、车辆数据集和生成数据集。在第二部分,您将使用 Keras 库预测不同数据集的输出,例如随机数据集、国际航空乘客数据以及洛杉矶气温预测。 重要信息:如果您觉得本课程对您的职业没有帮助,您受益于 30 天退款保证,完全退款,无需提问!一旦注册,您将终身无限制访问课程!您将立即获得任何更新的免费访问权限,并将获得我对课程相关问题或建议的全力支持。请查看课程大纲和免费预览讲座以快速了解。 现在是采取行动的时候!点击右上角的“参加此课程”按钮!不要浪费时间!每一秒都宝贵。我期待在课程中见到您! 诚挚问候,Sobhan
Artificial neural networks (ANNs) or connectionist systems are computing systems vaguely inspired by the biological neural networks that constitute animal brains. Such systems "learn" to perform tasks by considering examples, generally without being programmed with any task-specific rules. For example, in image recognition, they might learn to identify images that contain cats by analyzing example images that have been manually labeled as "cat" or "no cat" and using the results to identify cats in other images. They do this without any prior knowledge about cats, e.g., that they have fur, tails, whiskers and cat-like faces. Instead, they automatically generate identifying characteristics from the learning material that they process. An ANN is based on a collection of connected units or nodes called artificial neurons which loosely model the neurons in a biological brain. Each connection, like the synapses in a biological brain, can transmit a signal from one artificial neuron to another. An artificial neuron that receives a signal can process it and then signal additional artificial neurons connected to it. In common ANN implementations, the signal at a connection between artificial neurons is a real number, and the output of each artificial neuron is computed by some non-linear function of the sum of its inputs. The connections between artificial neurons are called 'edges'. Artificial neurons and edges typically have a weight that adjusts as learning proceeds. The weight increases or decreases the strength of the signal at a connection. Artificial neurons may have a threshold such that the signal is only sent if the aggregate signal crosses that threshold. Typically, artificial neurons are aggregated into layers. Different layers may perform different kinds of transformations on their inputs. Signals travel from the first layer (the input layer), to the last layer (the output layer), possibly after traversing the layers multiple times. The original goal of the ANN approach was to solve problems in the same way that a human brain would. However, over time, attention moved to performing specific tasks, leading to deviations from biology. ANNs have been used on a variety of tasks, including computer vision, speech recognition, machine translation, playing board and video games and medical diagnosis. In this Course you learn multilayer perceptron (MLP) neural network by using Scikit learn & Keras libraries and Python.You learn how to classify datasets by MLP Classifier to find the correct classes for them.
