An Alternative Model for Coherent Sheaves over Noetherian Schemes
The category of coherent sheaves over a noetherian scheme is very important for studying the properties of a given scheme. For noetherian schemes it is a well-known fact that the topology can be fully recovered from the corresponding partially ordered set of its points together with the specializaion partial order. Here we show that the same thing holds for the category of coherent sheaves over a noetherian scheme, i.e. there exists an equivalent description of this category in the "language" o…

John Ruskin said: 'There is No Wealth but Life.'
What I had to do was find and explore new ways of seeing it.
Once I did, I never felt alone.
Cultivating alternative ways of experiencing the world has completely changed my life;
it helped me overcome anxiety and depression, opened up a world of possibility and led me to a new career in photography.

Answer Matching Outperforms Multiple Choice for Language Model Evaluation
Multiple choice benchmarks have long been the workhorse of language model evaluation because grading multiple choice is objective and easy to automate. However, we show multiple choice questions from popular benchmarks can often be answered without even seeing the question. These shortcuts arise from a fundamental limitation of discriminative evaluation not shared by evaluations of the model's free-form, generative answers. Until recently, there appeared to be no viable, scalable alternative to…

Why is school lunch debt a thing? There's got to be a better way to handle it than to take a kid's lunch away from them. If the school can afford to give them an "alternative meal," why can't they afford to give them the original meal?

Beyond Wellbeing Apps: Co-Designing Immersive, Embodied, and Collective Digital Wellbeing Interventions for Healthcare Professionals
Healthcare professionals (HCPs) face increasing levels of stress and burnout. Technological wellbeing interventions provide accessible and flexible support for HCPs. While most studies have focused on mobile- and web-based programs, alternative technologies like virtual reality (VR), augmented reality (AR), tangible interfaces, and embodied technologies are emerging as engaging and effective tools for wellbeing interventions. However, there is still a lack of research on how such technologies a…

Steering Robots with Inference-Time Interactions
Imitation learning has driven the development of generalist policies capable of autonomously solving multiple tasks. However, when a pretrained policy makes errors during deployment, there are limited mechanisms for users to correct its behavior. While collecting additional data for finetuning can address such issues, doing so for each downstream use case is inefficient at deployment. My research proposes an alternative: keeping pretrained policies frozen as a fixed skill repertoire while allow…

Magnetoencephalography (MEG) Based Non-Invasive Chinese Speech Decoding
As an emerging paradigm of brain-computer interfaces (BCIs), speech BCI has the potential to directly reflect auditory perception and thoughts, offering a promising communication alternative for patients with aphasia. Chinese is one of the most widely spoken languages in the world, whereas there is very limited research on speech BCIs for Chinese language. This paper reports a text-magnetoencephalography (MEG) dataset for non-invasive Chinese speech BCIs. It also proposes a multi-modality assis…

I know that anything with aquarium on it costs more, but the aquarium tax for snowflake food is ridiculous. I've been keeping shrimp for less than a year, so maybe other shrimp keepers already know about this cheap alternative to snowflake food, but in case you didn't -
After watching some YT shrimp keeper channels, I've been feeding my neocaridina colony snowflake food a couple of times a week. They like it and I was almost out, so I was looking at the bag and realized it only has one ingredient - soy hulls. I paid $12 for 3 1/2 ounces of snowflake food.
I thought there must be a cheaper source, so I looked online and found soy hull pellets for mushroom cultivation were 10 pounds for $20. The pellets are exactly the same size as the ones in the snowflake food bag, and my colony eats them just as eagerly.
Snowflake food: $3.70 an ounce.
Bulk organic soybean husks: $0.13 an ounce. 28x cheaper.
