Core Insights - The launch of the college entrance examination application model "KaoPu AI 3.0" by KaoPu AI in collaboration with Peking University marks a significant technological breakthrough in the college application industry, improving admission prediction accuracy by an average of 30% compared to traditional software [1][5]. Group 1: Model Performance - KaoPu AI 3.0 demonstrated impressive predictive performance, with over 90% of 985 and 211 universities showing an absolute score error of within 3 points when comparing predicted scores to actual scores from 2024 [3][6]. - For public undergraduate institutions (excluding 985 and 211), over 90% had an absolute score error of within 5.5 points, significantly outperforming traditional application software [3][6]. Group 2: Innovative Methodology - The new prediction method, "Graph Embedding," developed by KaoPu AI and Peking University, utilizes historical admission data to uncover deeper connections and patterns among universities and majors, enhancing the prediction of admission probabilities [6][8]. - This method combines graph embedding technology with probability estimation, providing substantial improvements in admission prediction accuracy compared to traditional methods [8]. Group 3: Expanded Options for Students - The model broadens the range of recommended universities and majors by calculating the similarity between different programs based on admission difficulty, helping students discover overlooked options that align with their profiles [9]. - This is particularly beneficial in competitive fields or when enrollment plans are reduced, allowing students to consider alternative choices [9]. Group 4: Enhanced Strategy Setting - The model allows for a more scientific and granular approach to setting application strategies, enabling students and parents to assess the risk levels of different choices based on estimated admission probability distributions [10]. - It facilitates the construction of a more reasonable application gradient by correlating target ranks with strategies such as "reach," "steady," and "safety" [10]. Group 5: Visualizing Competition - The model provides visualizations of the distribution of universities and majors in the embedding space, helping students and parents understand the competitive landscape within specific score ranges [11]. - This analysis aids in identifying clusters of similar programs, enhancing the understanding of overall competition dynamics [11]. Group 6: Availability - The "Graph Embedding" method has been fully integrated into the KaoPu AI app and PC version, allowing parents and students to experience its features at any time [12].

1、 适度的乐观才是对的。而在这个前提下,你必须学会选择自己的战场。 2、 从投资回报的角度看,我在过去二十年中作为 Founders Fund创始合伙人尝试过的各类投资里, 表现最差的两个领域,就是教育软件和医疗信息化。 3、 当所有人都认同这是一件 "显而易见的大事"时,如果你不能拿出一种完全不同的视角,你就几乎 没戏。 两人多年好友,对话没有太多寒暄,直接切入问题本身: "在一个越来越多系统坏掉的时代,聪明人该怎么选择战场?" 他吐槽了很多美国政府系统失灵的、不可思议之处。比如 地铁 , 美国修建 1 英里 需要 10 亿美元, 10倍于伦敦搭建的成本;政 府预算明面上写着 "援助非洲",实际上却是给政党选举买单 …… 反倒是那些不那么热门、但你有独特认知差的地方,更容易挖出真正的机会。 4、 你不能什么都干。你不能像一个冲浪者,在一个没有浪的平静日子里拼命划水。 你要等到有浪来的时候,在恰当的位置发力 ,才会有效果。 彼得 ·蒂尔(Peter Thiel) 在中国 最广为人知的身份,可能是《从 0到1》 的 作者,是支持特朗普的 硅谷少数派,是与马斯克曾在 PayPal一起打天下的早期合伙人。 他是 ...
