The Hidden Cost of Defaults in Recommender System Evaluation
Hyperparameter optimization is critical for improving the performance of recommender systems, yet its implementation is often treated as a neutral or secondary concern. In this work, we shift focus from model benchmarking to auditing the behavior of RecBole, a widely used recommendation framework. We show that RecBole's internal defaults, particularly an undocumented early-stopping policy, can prematurely terminate Random Search and Bayesian Optimization. This limits search coverage in ways tha…

Credit Default Prediction with Projected Quantum Feature Models and Ensembles
Accurate prediction of future loan defaults is a critical capability for financial institutions that provide lines of credit. For institutions that issue and manage extensive loan volumes, even a slight improvement in default prediction precision can significantly enhance financial stability and regulatory adherence, resulting in better customer experience and satisfaction. Datasets associated with credit default prediction often exhibit temporal correlations and high dimensionality. These attr…

Unmute the Patch Tokens: Rethinking Probing in Multi-Label Audio Classification
Although probing frozen models has become a standard evaluation paradigm, self-supervised learning in audio defaults to fine-tuning. A key reason is that global pooling creates an information bottleneck causing linear probes to misrepresent the embedding quality: The $\texttt{cls}$-token discards crucial token information about dispersed, localized events in multi-label audio. This weakness is rooted in the mismatch between the pretraining objective (operating globally) and the downstream task …

Did someone figure out how to configure the network for the Apple Container service bridge interface permanently? it's not what ```defaults write com.apple.container network.subnet ... ``` does ....

Anyone figured out some magic defaults write command on #macOS #Tahoe #tahoe26 that can reduce the ridiculous large corner radius?

A paradox I think about:
If advertising doesn’t work - why is that the business model nearly every internet business defaults to?
If advertising online is so lucrative, why are marketing departments all over failing to meet targets and struggling to show any results?
Everything is ads and none of it is working. And I’m just a lone marketer screaming in this forest of nonsense hoping some tree falls and hears me.

Collateral and Reputation in a Model of Strategic Defaults

Collateral and Reputation in a Model of Strategic Defaults
This paper builds a finite-horizon model to study the role of physical collateral in a model of strategic defaults, when the borrower can develop reputation for honesty. Asset ownership increases attractiveness of the reputational channel: the borrower who would prefer to remain in autarky in the absence of the asset prefers to apply for collateralized debt. Pledging the asset as collateral facilitates reputation building, which is especially successful at the times of asset price drops, becaus…

@… I'm not familiar with the third-party screenshot options, but if you use the built-in system shortcut and option-click on the window (or use the defaults write command from that article to make "no shadows" the default), those corners should be fully transparent.
Like this?

@lolxd292@mastodon.social Yes, because the UI expects that if you reply to a conversation, you intend to converse with the whole conversation. Usually that's correct, but if your intention differs from the defaults, you'll need to adjust that action.

I love how, on most Linux distros, you can just do an update and upgrade despite not having touched them for a long time, and you just wait for a little bit, potentially optionally reboot, and there are no nags or new things someone wants to sell you or settings that have changed back to vendor defaults. You just get on with what you wanted to do with shiny, freshly-updated software.
Arch-based distros have been the exception from the experience above for me, but I guess that’s the co…

I don't understand why so few people use openSUSE compared to Fedora, Debian, Ububububu, and the meme distros (btw). It's basically perfect. It has every package you could hope for, even Nvidia and Steam, right there in the repo. Tested packages with snapshots for rollback. Doesn't force Wayland (yet?). The sensible defaults on weird hardware work great. Why waste time with anything else? I'm old and grumpy now, I just want a *nix computer, not a hobby.

Now, anyone can quote. I went into preferences and posting defaults.
This is a great feature. I think a "normal Mastodon" should have quote posts.
Abnormality comes with the lack of it!
I love it! It's beautiful!
Btw, you can edit your post and then the interface tells me I can add a quote post to my post but it didn't work in the end.
Now time to fix all the bugs that arrived due to this new feature being introduced...
Poor programmers, …

My macOS laptop has felt... less than responsive of late.
I'm thinking about hitting the restore-to-factory-defaults type button and using Time Machine to bring stuff back.
I haven't done this procedure in probably 5-10 years.
Any hiccups or pitfalls I should know about?

Why Bonds Fail Differently? Explainable Multimodal Learning for Multi-Class Default Prediction
In recent years, China's bond market has seen a surge in defaults amid regulatory reforms and macroeconomic volatility. Traditional machine learning models struggle to capture financial data's irregularity and temporal dependencies, while most deep learning models lack interpretability-critical for financial decision-making. To tackle these issues, we propose EMDLOT (Explainable Multimodal Deep Learning for Time-series), a novel framework for multi-class bond default prediction. EMDLOT integrat…

Filling MIDI Velocity using U-Net Image Colorizer
Modern music producers commonly use MIDI (Musical Instrument Digital Interface) to store their musical compositions. However, MIDI files created with digital software may lack the expressive characteristics of human performances, essentially leaving the velocity parameter - a control for note loudness - undefined, which defaults to a flat value. The task of filling MIDI velocity is termed MIDI velocity prediction, which uses regression models to enhance music expressiveness by adjusting only th…
