Definition 2.4. Given an alphabet Σ, given any two strings u, v ∈ Σ∗ we define the following notions as follows:
We say that u is a proper prefix (suffix, substring) of v iff u is a prefix (suffix, substring) of v and u ̸= v.

EENT(Engineering ENTrepreneurship)
Engineers and scientists create and lead great companies, hiring managers when and where needed to help execute their vision. Designed expressly for students having a keen interest in technological innovation, this course investigates the roles of inventors and founders in successful technology ventures. Through case studies and guest speakers, we introduce the knowledge and skills needed to recognize and seize a high-tech entrepreneurial opportunity - be it a product or service - and then successfully launch a startup or spin-off company. The course studies key areas of intellectual property, its protection and strategic value; opportunity analysis and concept testing; shaping technology driven inventions into customer-driven products; constructing defensible competitive strategies; acquiring resources in the form of capital, people and strategic partners; and the founder's leadership role in an emerging high-tech company. Throughout the course emphasis is placed on decisions faced by founders, and on the sequential risks and determinants of success in the early growth phase of a technology venture. The course is designed for, but not restricted to, students of engineering and applied science and assumes no prior business education. Prerequisite: Third or Fourth year or Graduate standing

激活函数（Activation Function）
常见的激活函数都是非线性的，因此也会给神经元引入非线性元素，使得神经网络可以逼近其他的任何非线性函数，这样可以使得神经网络应用到更多非线性模型中。
小红书推荐算法组招聘实习生参与如下方向的技术研究和落地工作：
重排算法：基于序列生成与模型评估的两阶段排序框架，从精排候选集中产生最终的展示序列，在确保推荐多样性的情况下最大化整页效率；
混排算法：探索如何将业务目标不同的社区笔记（for时长）、电商笔记（for成交）、广告笔记（for营收）进行统一混排，取得多方共赢的结果。
涉及技术点包括Listwise建模、生成模型、强化学习、运筹优化等。由于重排、混排在业界还没有固定范式，有很大创新机会，鼓励实习期间有论文产出。
