你好,我是悦创,欢迎来到前端工程师的 AI 实战课。
我算是国内探索 AI+ 前端领域比较早的一拨人。在各种大模型产品受到广泛关注之前,就已经开始尝试 AI 出码、UI 千人千面等诸多方式,帮助前端工程师提效,也给产品创新带来更多可能。
我曾有两段工作经历和 AI 紧密相关,现在回想起来感觉自己还挺幸运的。
一个是在腾讯游戏的数据平台,主要做 Web 端游戏视频的智能剪辑功能研发。这让我深入了解了如何利用 AI 技术优化剪辑效果,提升视频内容的质量,给用户带来更好的观看体验。这也是我开始接触并思考端侧模型的开始。
Instructions: This homework is to be submitted on GradeScope as a single pdf (not in parts) by 11:59 pm on the due date. You may either type your solutions in a word processor and print to a pdf, or write them by hand and submit a scanned copy. Do write and submit your answers as if they were a professional report. There will be point deductions if the submission isn’t neat (is disordered, difficult to read, scanned upside down, etc...).
Question 1
Consider the following unnormalized posterior:
Q1
In a PCB manufacturing company, a new product needs to be produced. The customer needs 1,000 PCBs. However, some of the PCBs may get rejected at the final inspection stage due to manufacturing defects. Therefore, if the company starts to manufacture only 1,000 PCBs, they may end up having less than 1,000 PCBs and may not be able to meet the customer demand. It takes about two weeks to produce PCBs, so there is not enough time to go back and make up for the shortage. One possible way to overcome this issue is to launch

Nobody goes there anymore. It's too crowded.
Yogi Berra
You've probably seen movies with crowds of people. While they might sometimes use real people, nowadays crowds are often computer-generated. This gives the film-makers more control over the size and behaviour of the crowd, and probably saves them money as well.

Instructions
- Submit your responses in a single knitted file, following the Homework Structure which requires model outputs, plots, and code for all questions to be submitted in a single HTML file by Sept 29 at 11:59 p.m. Eastern**. [Time converter]**
- The solutions will be made available on Oct 1 at 1:00 a.m. Eastern. You will need to assess three of your peers to complete the Data Analysis by Oct 6 at 11:59 p.m. Eastern**. Students who do not submit the graded assessments before the deadline will receive a zero on their own Data Analysis.**
- Before you begin, please review the following document: DONT_CHEAT.docx. Cheating is not helping you learn and be successful. It does the opposite. While you may collaborate with other students, please submit your own responses to the data analysis questions. Please refrain from consulting prior homework solutions or other materials that provide answers to the data analysis questions. Any case identified as potential plagiarism will result in a zero grade for the assignment and it will be reported to the OMSA program.
Introduction
This project is inspired by a genre of video game, where players choose the actions that their characters take in a turn-based battle. Some examples include the battle systems in Super Mario RPG, Pokémon, Final Fantasy and table-top games like Dungeons and Dragons.
Question 1
Three devices are monitored until failure. The observed lifetimes are 1.1, 2.2, and 0.4 years. If the lifetimes are modeled as exponential distribution with rate ,
Instructions:
- Print your First and Last name and NetID on your answer sheets
- Submit all your answers including Python scripts and report in a single Jupyter Lab file (.ipynb) or along with a single PDF to Brightspace by due date. No other file formats will be graded. No late submission will be accepted.
- Total 5 problems. Total points: 100

二叉树(Binary Tree)是一种非线性数据结构,代表“祖先”与“后代”之间的派生关系,体现了“一分为二”的分治逻辑。与链表类似,二叉树的基本单元是节点,每个节点包含值、左子节点引用和右子节点引用。
class TreeNode:
"""二叉树节点类"""
def __init__(self, val: int):
self.val: int = val # 节点值
self.left: TreeNode | None = None # 左子节点引用
self.right: TreeNode | None = None # 右子节点引用
Due dates:

你好,我是悦创。
Java 的 Builder 模式(建造者模式)是一种设计模式,通常用于构建复杂对象。它通过一步步地构建一个对象来避免构造函数参数过多的问题,同时提高代码的可读性和灵活性。我们可以通过 Builder 模式在构建对象时指定我们需要的字段,而不必每次都传递所有的参数。
1. 什么时候使用 Builder 模式?
- 构造函数参数过多:如果类有多个可选参数,直接使用构造函数可能会显得混乱。
- 对象不可变:通过 Builder 模式,创建对象的过程在构造完成之后就不会再被修改。
- 提高可读性:可以按需设置不同的参数,而不用处理多个构造函数的重载。
