PostgreSQL Full-Text Search: Fast When Done Right (Debunking the Slow Myth)
PostgreSQL's built-in full-text search can achieve significant performance improvements, up to 50x faster, when properly optimized with techniques such as pre-calculating and storing tsvector values and using GIN indexes with fastupdate=off. A recent benchmark by Neon comparing their pg_search extension to PostgreSQL's standard full-text search may have unintentionally handicapped the baseline setup, leading to misleading conclusions about the performance of standard FTS.
Fake job seekers are flooding US companies that are hiring for remote positions
Fake job seekers are using AI to interview for remote jobs, creating fake identities, employment histories, and even generating answers to interview questions, according to tech CEOs. By 2028, it's estimated that 1 in 4 job candidates globally will be fake, posing a significant threat to companies, including the risk of malware installation, data theft, and financial loss.

NNN: Next-Generation Neural Networks for Marketing Mix Modeling
NNN is a Transformer-based neural network approach to Marketing Mix Modeling (MMM) that uses rich embeddings and attention mechanisms to capture complex interactions and long-term effects. The model demonstrates improved predictive power and provides valuable insights through model probing, making it a more effective and interpretable alternative to traditional MMM methods.
ProtoGS: Efficient and High-Quality Rendering with 3D Gaussian Prototypes
The ProtoGS method learns Gaussian prototypes to represent Gaussian primitives, reducing the total number of Gaussians required for 3D Gaussian Splatting without sacrificing visual quality. This approach enables efficient rendering, achieves a substantial reduction in the number of Gaussians, and maintains or enhances rendering fidelity, outperforming existing methods on real-world and synthetic datasets.
Visualizing a Million Time Series with the Density Line Chart
Data analysts often struggle to visualize multiple series of data simultaneously without the charts becoming overwhelming. The DenseLines technique addresses this issue by calculating a discrete density representation of time series, allowing users to see aggregate trends and identify anomalies in multiple series at once.
A Comprehensive Survey on Long Context Language Modeling
This paper presents a comprehensive survey on recent advances in long-context modeling for large language models, covering aspects such as obtaining effective models, efficient training and deployment, and evaluation methods. The survey aims to provide a valuable resource for researchers and engineers, and also explores application scenarios and future development directions for Long Context Language Models (LCLMs).
Analyzing Dehumanizing Metaphors in Immigration Discourse with LLMs
Metaphorical language is prevalent in political discussions, particularly on social media, and can influence how people perceive issues like immigration. A computational approach was developed to measure metaphorical language in 400K US tweets about immigration, revealing that conservatives tend to use dehumanizing metaphors more than liberals, and that certain types of metaphors can increase user engagement, such as retweets.
