This article provides a comprehensive, beginner-friendly guide to the Polars library in Python, emphasizing its performance advantages over Pandas due to its Rust-based implementation, memory efficiency, and parallelism. It covers the installation process for Polars, explaining how to set up the environment using `pip` or `conda` and recommending Google Colab for immediate use without local installation. The tutorial then delves into core Polars concepts, defining and illustrating 'Series' (1-dimensional labeled data structures) and 'DataFrames' (2-dimensional collections of Series), including how to handle both homogenous and heterogenous data with schema enforcement. Practical examples are provided for creating Series and DataFrames, manipulating their schemas, and performing essential data inspection tasks using `head()`, `tail()`, and `glimpse()`. Furthermore, it explains how to combine DataFrames through concatenation (vertical stacking) and joining (based on shared keys), and how to add new columns with `with_columns()`. Finally, the article demonstrates reading CSV files with Polars, concluding with an initial look at a real-world dataset (Titanic) to solidify the learned concepts, preparing users for more advanced data manipulation.

This article details how the Xiaohongshu search team integrates Generative Relevance models with Reinforcement Learning to overcome the limitations of traditional discriminative models in complex semantic understanding and explainability. The core of the solution is the introduction of the "Stepwise Advantage Masking (SAM) Strategy," which optimizes the credit assignment mechanism in Reinforcement Learning by incorporating lightweight process supervision during multi-step reasoning. This method redefines relevance evaluation as a multi-step reasoning task that adheres to relevance standards established by Xiaohongshu experts, executed through three stages: general semantic understanding, applying rule constraints, and result evaluation. The SAM strategy is crucial for its precise control over the Reinforcement Learning process, rewarding only correct reasoning steps. This effectively prevents the reinforcement of erroneous logic, significantly improving the model's learning efficiency and generalization ability. Both offline experiments and 7-day online A/B tests have validated the method's effectiveness, showing substantial improvements in user engagement and retrieval result relevance. The article concludes by envisioning the "Instruction Relevance-LLM" concept, aiming for future dynamic rule adaptation to evolving business logic.

This article uses an interview with MiniMax founder Yan Junjie and Luo Yonghao as a starting point, showcasing how Yan Junjie, as an "entrepreneur eager for pure technology," upholds his technological ideals. It reviews the limitations of models being treated as tools in the AI 1.0 era, and Yan Junjie's journey since being inspired by the CLIP paper in 2020 to fully commit to AGI entrepreneurship. The text emphasizes the decisive role of technical capabilities in product form and MiniMax's 'pure' decision to persist with MoE architecture and full-modal research and development, despite high computing costs and multiple pre-training failures. The article details how MiniMax, in '2025' (a future year envisioned by the author), tackled the impact of the domestic large-scale AI model industry by fighting three tough battles: architectural innovation, underlying algorithm output, and defining interaction standards, ultimately establishing 'directional confidence' in its technology. Finally, the article advocates for the business world to embrace technological ideals and affirms the value and significance of Chinese AI enterprises building confidence in global AI competition through their efficiency advantages.

This article reports on the speech given by Yuan Lin, founder and CEO of Teeni.AI, at the GeekPark Innovation Festival. She highlighted that Gen Z perceives AI as 'as natural as air,' with their demands evolving from tool utilization to efficiency enhancement and emotional connection. Addressing the unique characteristics of this generation, Teeni.AI has developed an intelligent partner through its exclusive hardware, 'Tinli Bear' (听力熊), and a large model developed in collaboration with Alibaba Tongyi specifically for teenagers, offering multimodal, memory-enabled, planning, and empathetic capabilities. The article stresses that AI should function as 'scaffolding' to ignite children's creativity, rather than merely providing answers. It also envisages a future where human-machine relationships transition from simple 'interaction' to profound 'symbiosis,' advocating for a pure and nurturing AI environment for children's development.

This article argues that overload protection, encompassing rate limiting, quotas, and adaptive concurrency, should be a core pillar of platform engineering, alongside established areas like CI/CD and observability. The author highlights that current ad hoc approaches to handling system overloads lead to fragmented reliability, inconsistent behavior, and significant technical debt. By providing centralized, consistent frameworks for overload protection, platforms can enable self-regulating systems, prevent cascading failures, and ensure predictable performance. The article details three key capabilities: declarative rate limiting, a centralized quota service, and adaptive load shedding, all supported by clear visibility through APIs and dashboards. Neglecting this leads to fragile ecosystems, unpredictable failures, and high costs in the long run, whereas a platform-owned solution frees developers to focus on product features.

This article challenges the simplistic view of UX as merely 'art and science,' introducing a more nuanced 'three lenses' framework: Creativity, Science, and Business. It argues that while all UX professionals engage with these lenses, their emphasis varies significantly based on roles and individual strengths. This distinction is crucial because the industry often misrepresents UX as a single, catch-all capability, leading to frustration for designers, difficulty for hiring managers, and overlooking specialized roles like researchers. Drawing on Howard Gardner's theory of Multiple Intelligences, the author explains how different cognitive strengths naturally align with specific lenses. The article illustrates how these lenses manifest in practice through examples of UI Designers (creativity-led), UX Architects (business-led), and UX Researchers (science-led). It emphasizes that true value comes not from individuals mastering all three lenses, but from awareness of one's strengths and collaborative teamwork. This perspective is vital for building well-balanced UX teams that ensure emotional connection, behavioral truth, and commercial impact, preventing UX from being reduced to mere aesthetics or documentation. Product Design is highlighted as the overarching domain where these UX principles are applied.

This article introduces OpenAI's open-sourced Circuit Sparsity technology, designed to address the black-box problem prevalent in traditional Transformer models. It achieves this by setting 99.9% of a large model's weights to zero, making the model's computational process decomposable and understandable, and thus enabling a clear interpretation of AI's decision-making. This method facilitates the creation of minimal, functionally decoupled 'computational circuits' for specific tasks, allowing for precise tracking of model logic. The article contrasts Circuit Sparsity with current mainstream MoE models, noting that MoE's approach to sparsity via crude expert splitting can lead to issues such as expert homogenization and blurred functional boundaries. In contrast, Circuit Sparsity pursues native sparsity, inherently preventing information interference. While Circuit Sparsity currently faces challenges due to extremely high computational costs, the research team is actively exploring methods to extract sparse circuits from existing dense models or optimize training mechanisms to overcome these limitations. Their goal is to extend this technology to larger models, thereby significantly enhancing AI's interpretability.
