Python 是完全面向对象的编程语言,它也有类 (class) 与对象 (object) 的概念。 关于什么是面向对象,我想大家都已经或多或少的有所了解,这里就不做赘述了。 类(class) 与对象 (object) 是模型与实例的关系,它们有两方面的特征:属性 (attribute) 与方法 (method)。 Python 中类的定义方法如下: 这里pass 是...

这一步主要在Python中完成。模型部分选用的是朴素贝叶斯分类器(Naive Bayes Classifier),选用该算法是基于一个假设,即不同人做同一动作的体态应该服从高斯分布。 # 首先导入必要的包 import numpy as np # 加载features和labels表格 X_train = np.loadtxt('features.csv',usecols = (0,1,2,3,4,5),delimiter...

如何使用一些基础的Python模块(只使用torch等基础库)就能从0复现SFT和DPO的整个训练过程 本文全部的代码复现已统一汇总打包于此项目: 1Transformer架构回顾 经典的Transformer的decoder-only架构的模型,在训练阶段(含预训练、监督式微调、DPO)的优化目标就是单纯的预测下一个词。
数据结构 From Zero To Hero(三) 發佈於 2021-02-15 本篇,我们来介绍除了数组之外另一种线性结构 —— 链表(LinkedList)。 链表解决了数组存在的很多问题,当然也引入了新的问题。不同于数组,链表可以自动缩放。 每个链表元素称为节点(Node),每个节点由两部分组成,分别称为数据域和指针域。我们把第一个节点称...
