Diverse Negative Sampling for Implicit Collaborative Filtering
Implicit collaborative filtering recommenders are usually trained to learn user positive preferences. Negative sampling, which selects informative negative items to form negative training data, plays a crucial role in this process. Since items are often clustered in the latent space, existing negative sampling strategies normally oversample negative items from the dense regions. This leads to homogeneous negative data and limited model expressiveness. In this paper, we propose Diverse Negative …

Why Is Japan Still Investing In Custom Floating Point Accelerators?
It has taken nearly two decades and an immense amount of work by millions of people for high performance computing to go mainstream with GenAI. And now,

The Expressions of Depression and Anxiety in Chinese Psycho-counseling: Usage of First-person Singular Pronoun and Negative Emotional Words
This study explores the relationship between linguistic expressions and psychological states of depression and anxiety within Chinese psycho-counseling interactions, focusing specifically on the usage of first-person singular pronouns and negative emotional words. Utilizing a corpus derived from 735 online counseling sessions, the analysis employed a general linear mixed-effect model to assess linguistic patterns quantified by the Linguistic Inquiry and Word Count (LIWC) software. Results indic…

Non-existence of negative derivations on the higher Nash blowup local algebra
Let $f\in\mathbb{C}[x_1,\ldots,x_s]$ be a weighted homogeneous polynomial having an isolated singularity and $\mathcal{T}_n(f)$ be its higher Nash blowup local algebra. We show that $\mathcal{T}_n(f)$ does not admit negative weighted derivations for $n\geq2$. This answers affirmatively a conjecture of Hussain-Ma-Yau-Zuo.

It does have use cases (we use it for prototyping spatial experiences at work) but for mainstream use that is spot on. The tech doesn't work good enough to combat all the negative aspects that come with its usage.

Elastic Buffer Design for Real-Time All-Digital Clock Recovery Enabling Free-Running Receiver Clock with Negative and Positive Clock Frequency Offsets
We present an elastic buffer design that enables all-digital clock recovery implementation with free-running receiver clock featuring negative and positive clock frequency offsets. Error-free real-time data transmission is demonstrated from -400 ppm to +400 ppm.

wikiconflict: Wikipedia edit wars (2009)
A network representing editorial interactions among editors of the English Wikipedia. Nodes are editors, and an edge denotes an edit conflict between the two editors. Edge are timestamped and signed. A positive sign indicates the users have agreement on the edit, and the negative sign indicates a disagreement (a reversion) on the edit.
This network has 118100 nodes and 2917785 edges.

Benefiting from Negative yet Informative Feedback by Contrasting Opposing Sequential Patterns
We consider the task of learning from both positive and negative feedback in a sequential recommendation scenario, as both types of feedback are often present in user interactions. Meanwhile, conventional sequential learning models usually focus on considering and predicting positive interactions, ignoring that reducing items with negative feedback in recommendations improves user satisfaction with the service. Moreover, the negative feedback can potentially provide a useful signal for more acc…
