Architecture Soft Skills Part 1

Software Architecture Fundamentals: Understanding the Basics

In this chapter, we’re going to be looking at some of the soft skills that an architect needs when becoming an architect from developer, that it’s a very ill-defined role. There are literally doze...

Machine Learning Introduction

机器学习介绍

监督学习 (Supervised Learning) 监督学习是利用训练数据集学习一个模型,再利用模型对测试样本集进行预测。 二分类模型: 预测出生小孩性别,输出结果只有两个维度 (男,女) 多分类模型: 预测出生小孩性别,输出结果有多个维度 (男,女,不男不女) 回归模型: 预测出生小孩性别概率,输出结果男的概率是多少,女的概率是多少 监督学习是最常见的机器学习...
