Graphomane | Neal Stephenson | Substack
Neal Stephenson's Substack. Mostly about the intersection of tech and art, with some excursions, digressions, and tangents. I will talk about projects I'm actively working on. I have a personal financial interest in some of those. Click to read Graphomane, by Neal Stephenson, a Substack publication with thousands of subscribers.

Right-wing (people's) hypocrisy
Isn't it interesting how someone first criticizes someone (I didn't listen to their conversation enough to know who was it about) using Polish insults for left-wing people, adding "nothing is sacred to them", and then buys a ticket to a train that's financed from the budget, and on top of that benefits from discount for disabled people and their guardians (both being left-wing inventions).

Warum hinkt Deutschland bei der #Verkehrswende hinterher? 🚆Die Investitionen in das #Schienennetz sind im internationalen Vergleich erschreckend gering. Wussten Sie, dass Länder wie die #Schweiz

Die Verkehrswende braucht ein starkes Schienennetz, doch Deutschland investiert zu wenig in die Infrastruktur
Die Verkehrswende braucht ein starkes Schienennetz, doch die Finanzierung des Aufbaus und Ausbaus ist eine riesige Herausforderung.

On the Comprehensibility of Multi-structured Financial Documents using LLMs and Pre-processing Tools
The proliferation of complex structured data in hybrid sources, such as PDF documents and web pages, presents unique challenges for current Large Language Models (LLMs) and Multi-modal Large Language Models (MLLMs) in providing accurate answers. Despite the recent advancements of MLLMs, they still often falter when interpreting intricately structured information, such as nested tables and multi-dimensional plots, leading to hallucinations and erroneous outputs. This paper explores the capabilit…

Ich bin mit einem Internet mit kostenfreien weil prä-kommerziellen, von Usern generierten und betriebenen Tools, Servern und Inhalten sozialisiert, und ich merke auch, daß ich einen inneren Widerstand gegen Bezahl­angebote habe. Gleichzeitig ist das Netz ein riesiges Multi­milliarden­geschäft, das sich zu großen Teilen aus Werbung¹ finanziert.
Also letztlich bezahlt der Werbungs­induzierte Turnschuhkauf (von anderen) mein Internet. Und auch das – fast ausschließlich indirekte Finanzier…

Multimodal Financial Foundation Models (MFFMs): Progress, Prospects, and Challenges
Financial Large Language Models (FinLLMs), such as open FinGPT and proprietary BloombergGPT, have demonstrated great potential in select areas of financial services. Beyond this earlier language-centric approach, Multimodal Financial Foundation Models (MFFMs) can digest interleaved multimodal financial data, including fundamental data, market data, data analytics, macroeconomic, and alternative data (e.g., natural language, audio, images, and video). In this position paper, presented at the MFF…

Lie Symmetry Net: Preserving Conservation Laws in Modelling Financial Market Dynamics via Differential Equations
This paper employs a novel Lie symmetries-based framework to model the intrinsic symmetries within financial market. Specifically, we introduce Lie symmetry net (LSN), which characterises the Lie symmetries of the differential equations (DE) estimating financial market dynamics, such as the Black-Scholes equation. To simulate these differential equations in a symmetry-aware manner, LSN incorporates a Lie symmetry risk derived from the conservation laws associated with the Lie symmetry operators…
