Generative AI is extremely appealing for non-technical users, who feel like they’ve gained access to magic powers. But as this story shows, a little knowledge is a dangerous thing. The Magic Genie Once upon a time, there was a Chief Data Officer who believed that the new wave of Generative AI, such as ChatGPT and Gemini, could bridge any technical hurdle. At a local AI meetup, they met a founder with no technical background who had proudly built […]

When OpenAI’s list of its top 30 customers by token consumption surfaced across social channels, the immediate reaction focused on who appeared on the list. But the more important insight came from the pattern: a mix of large, mature enterprises and fast-moving AI-native startups all consuming tokens at similar scales. This wasn’t a leaderboard of experimentation. It was a snapshot of where cognition-heavy work is already being automated—and where AI has quietly become embedded infrastructure. It’s also important to understand […]

We present a geometric framework for Reinforcement Learning (RL) that views policies as maps into the Wasserstein space of action probabilities. First, we define a Riemannian structure induced by stationary distributions, proving its existence in a general context. We then define the tangent space of policies and characterize the geodesics, specifically addressing the measurability of vector fields mapped from the state space to the tangent space of probability measures over the action space. Next, we formulate a general […]

The communication bottleneck in federated learning (FL) has spurred extensive research into techniques to reduce the volume of data exchanged between client devices and the central parameter server. In this paper, we systematically classify gradient and model compression schemes into three categories based on the type of correlations they exploit: structural, temporal, and spatial. We examine the sources of such correlations, propose quantitative metrics for measuring their magnitude, and reinterpret existing compression methods through this unified correlation-based framework.

On April 2, 2026, the IMF published a note signed by Tobias Adrian that comes as a wake-up call: the tokenization of financial assets is not a marginal improvement of infrastructure. It is a structural reconfiguration of global finance, and it carries systemic vulnerabilities that regulators do not yet master. But the IMF stops where the question becomes truly interesting. I) What the IMF saw The note identifies four distinct risks. The one that stands out the most, […]

For six months, I was forwarding YouTube links with messages like watch this when you get a chance. Nobody watched them. I know because I checked. I run a PR agency. Fifteen people spread across multiple cities, handling 90+ clients, pushing out content across 100+ websites. The kind of operation where every saved hour compounds. So when AI tools started getting genuinely capable – not just demo-reel capable – I wanted my team on board fast. My first […]

Recent advances in query optimization have shifted from traditional rule-based and cost-based techniques towards machine learning-driven approaches. Among these, reinforcement learning (RL) has attracted significant attention due to its ability to optimize long-term performance by learning policies over query planning. However, existing RL-based query optimizers often exhibit unstable performance at the level of individual queries, including severe performance regressions, and require prolonged training to reach the plan quality of expert, cost-based optimizers. These shortcomings make learned query optimizers […]

As global commerce continues to evolve, companies are under increasing pressure to offer more than a single product or a short-term transaction. People are looking for ecosystems that create ongoing value, fit into everyday life, and give them more reasons to stay engaged over time. JIFU has built its business around that idea. By bringing together travel, wellness, and financial education within one platform, the company has created a model that is designed to be both practical and […]
