Are Language Models Useful for Time Series Forecasting? (No.)
Skip to main content View PDF HTML (experimental) Abstract:Large language models (LLMs) are being applied to time series forecasting. But are language models actually useful for time series? In a series of ablation studies on three recent and popular LLM-based time series forecasting methods, we find that removing the LLM component or replacing it with a basic attention layer does not degrade forecasting performance -- in most cases, the results even improve! We also find that despite their significant computational...

Implementing SM-2 in Rust
I’ve been on a spaced repetition (SR) kick as of late. Mochi, the SR software I use, uses a modified version of the SuperMemo SM-2 algorithm to schedule cards. The differences are: The ease factor (EF) of the cards is not adjusted in response to performance, but can be changed manually. The justification is this avoids a purported problem with SM-2 called “ease hell”. When you fail a card, the interval to the next review is not reset but halved....

What can strong engineers do that weak engineers can't?
Right now people are blowing up on Twitter about whether the USA needs to import top talent from other countries, and if that means that American home-grown engineering talent is weak. Last month, people were blowing up over a study that purported to show that ~9.5% of software engineers do effectively zero work, and are effectively defrauding the company. And for the last ten years, people have been talking and writing about the fabled “10x engineer”. What does it really...

Quiver: A Modern Commutative Diagram Editor
quiver is a modern, graphical editor for commutative and pasting diagrams, capable of rendering high-quality diagrams for screen viewing, and exporting to LaTeX via tikz-cd. Creating and modifying diagrams with quiver is orders of magnitude faster than writing the equivalent LaTeX by hand and, with a little experience, competes with pen-and-paper. Try quiver out: q.uiver.app quiver features an efficient, intuitive interface for creating complex commutative diagrams and pasting diagrams. It's easy to draw diagrams involving pullbacks and pushouts, adjunctions, and...

The CAP theorem of Clustering: Why Every Algorithm Must Sacrifice Something
As software engineers, we use clustering algorithms all the time. Whether it's grouping similar users, categorizing content, or detecting patterns in data, clustering seems deceptively simple: just group similar things together, right? You might have used k-means, DBSCAN, or agglomerative clustering, thinking you just need to pick the right algorithm for your use case.But here's what most tutorials won't tell you: every clustering algorithm you choose is fundamentally flawed. Not because of poor implementation or wrong parameters, but because of...

Neutron Stars with Less Mass Than a White Dwarf Might Exist
Most of the neutron stars we know of have a mass between 1.4 and 2.0 Suns. The upper limit makes sense, since, beyond about two solar masses, a neutron star would collapse to become a black hole. The lower limit also makes sense given the mass of white dwarfs. While neutron stars defy gravitational collapse thanks to the pressure between neutrons, white dwarfs defy gravity thanks to electron pressure. As first discovered by Subrahmanyan Chandrasekhar in 1930, white dwarfs can...

Inverse Design of Complex Nanoparticle Heterostructures via DL on Graphs
26 December 2024, Version 1 Abstract Applications of deep learning (DL) to design nanomaterials are hampered by a lack of suitable data representations and training data. We report efforts to overcome these limitations and leverage DL to optimize the nonlinear optical properties of core-shell upconverting nanoparticles (UCNPs). UCNPs, which have applications in e.g., biosensing, super-resolution microscopy, and 3D printing, can emit visible and ultraviolet light from near-infrared excitations. We report the first large-scale dataset of UCNP emission spectra based on...

Zoning, initially designed to regulate land use and density, has evolved into a significant impediment for growing communities attempting to adapt to current circumstances. Restrictive land use regulations and zoning laws have been linked to higher housing prices, reduced construction activity, and a decrease in the elasticity of housing supply.1 Historically, zoning practices have been employed by affluent communities to boost property values, decrease tax burdens, and often impede the influx of non-white residents.2 Consequently, housing stock fails to meet...

I want to figure how to work with/ use Apple's developer resources for general purpose programming.

As Earth grows warmer, its ground is becoming drier and saltier, with profound consequences for the planet’s 8 billion inhabitants — nearly a third of whom already live in places where water is increasingly scarce and the ability to raise crops and livestock is increasingly difficult. Climate change is accelerating this trend. New research has found global warming has made 77 percent of the Earth’s land drier over the past three decades while rapidly increasing the proportion of excessively salty...

Ants and humans are also the only creatures in nature that consistently cooperate while transporting large loads that greatly exceed their own dimensions.

F*: A proof oriented general purpose programming language
F* (pronounced F star) is a general-purpose proof-oriented programming language, supporting both purely functional and effectful programming. It combines the expressive power of dependent types with proof automation based on SMT solving and tactic-based interactive theorem proving. F* programs compile, by default, to OCaml. Various fragments of F* can also be extracted to F#, to C or Wasm by a tool called KaRaMeL, or to assembly using the Vale toolchain. F* is implemented in F* and bootstrapped using OCaml. F*...
