Softmax forever, or why I like softmax

Kyunghyun Cho shares insights on the softmax function, discussing its advantages in transforming real vectors into categorical distributions under non-negativity and normalization constraints. He highlights its derivation from maximum entropy principles and emphasizes the intuitive learning signals it provides through interpretable gradients. Cho contrasts softmax with the harmonic formulation, critiquing its gradient behavior at the origin, which complicates learning. He suggests possible improvements and reflects on the importance of incremental progress in learning despite challenging gradients. Overall, he reaffirms his preference for softmax in machine learning contexts.

Summary: The main themes in the comments revolve around critiques of a research paper, specifically its methodology and assumptions. One commenter notes a significant flaw in the paper's reliance on a single hyperparameter configuration, indicating that "that's not an excuse for sloppy treatment of the rest of the paper." Another critique focuses on the paper's assumption that initial values |a_k| are approximately zero, arguing that this is incorrect due to the nature of distances between vectors as described in the cited original paper. They suggest that while "the gradient divergence near 0 could certainly be a problem," it may not be as detrimental as the author implies. Overall, the comments highlight concerns over methodological rigor and assumptions within the research.

Xbox Pushes Ahead with New Generative AI. Developers Say 'Nobody Will Want This'

Microsoft is advancing in generative AI for gaming with its new model, Muse, which aids developers in building games and optimizing classic titles for modern systems. However, the gaming community, including many developers, has reacted negatively, questioning the model's value and fearing it may undermine human creativity and job security. Critics argue that this focus on AI is driven more by shareholder interests than genuine benefits for game creators. While Microsoft sees potential in AI for game prototyping, there remains skepticism about its overall impact on the industry.

Google Is on the Wrong Side of History

The Electronic Frontier Foundation criticizes Google for shifting away from its original "Don't Be Evil" motto, particularly as it aligns more closely with the military-industrial complex. Google has revised its AI principles, removing prohibitions on using AI for weapons, surveillance, and harmful technologies. This shift raises concerns about the company's involvement in projects like Project Nimbus, which potentially enables surveillance in the Occupied Palestinian Territories. EFF warns that this trend could lead to significant humanitarian crises, urging Google to reconsider its actions as it prioritizes profit over human rights.

Summary: The discussion centers around the ethical implications of companies like Google retracting commitments against using AI for military and surveillance purposes. One commenter argues that the belief in humanity's fundamental goodness is naive, stating, “People sleep peaceably in their beds at night because rough robots stand ready to do violence on their behalf.” They express a preference for regulation reflecting societal values over corporate altruism, noting a recent shift away from voluntary ethical guidelines. Another contributor acknowledges the complexity of the situation, arguing that despite global challenges, Google still plays a role in countering harmful entities. The sentiments reveal a balance between skepticism towards corporate motives and recognition of the necessity of certain defenses in a complex world.

Large Language Diffusion Models

LLaDA (Large Language Diffusion with masking) is a newly introduced large language diffusion model that achieves competitive performance with models like LLaMA3 at an 8 billion parameter scale. It learns through a generative approach that masks tokens during pretraining and selectively unmasks them during supervised fine-tuning. The model showcases impressive scalability and diverse capabilities, including text generation, dialogue generation, math problem-solving, and translation. Case studies demonstrate its functionality across various applications, highlighting its versatility. The research is part of an ongoing exploration into improvements in language model efficiency and effectiveness.

Summary: The main themes in the comments revolve around concerns regarding the flexibility of input and output lengths in the discussed paper. One commenter questions the paper's ability to "support variable length for input and output," suggesting that it may not accommodate this feature. Another points out that the approach appears to rely on "EOS padding to create fixed length input/output," implying a potential limitation. Additionally, there is an inquiry about a "maximum output length," further indicating uncertainty about how the methodology handles varying output sizes. Overall, the comments express skepticism about the adaptability of the system outlined in the paper.

Speed Matters

The article emphasizes the importance of speed in coding and work processes. The author compares the development of two libraries, strucjure and rematch, highlighting a significant speed improvement in the latter's creation partly due to clearer goals and better practices. Achieving a tenfold increase in coding speed could allow for significantly more projects and learning opportunities, as faster coding reduces mental load and enables more experimentation. The author notes that small incremental improvements in processes can compound over time, leading to major gains in productivity and enjoyment in work.

Obscura VPN – Privacy that's more than a promise

Obscura VPN is a privacy-focused VPN that cannot log user activity or access internet traffic due to its unique design. It uses a two-party protocol and independent exit hops to separate user identity from browsing history, ensuring complete anonymity. Users can create accounts without personal information and pay via Bitcoin for enhanced privacy. Obscura's stealth protocol blends with regular internet traffic, making it less detectable by censorship filters. The service emphasizes transparency, allowing users to verify its claims through open source code and independent exit servers.

Cursed fire or #define black magic

The article explores the complexity and capabilities of the C preprocessor, particularly focusing on macros and whether they can implement Turing-complete functions. It discusses creating a fire animation using a defined width and height, applying motion blur effects, and eventually translating the code to a simpler language called "wend." The author uses macros to create recursive-like behaviors, demonstrating how C preprocessor limitations can be worked around to form recursive behaviors traditionally reserved for programming languages, supporting pseudo-recursion through creative macro definitions and expansions.
