Can fMRI reveal the representation of syntactic structure in the brain?
While studying semantics in the brain, neuroscientists use two approaches. One is to identify areas that are correlated with semantic processing load. Another is to find areas that are predicted by the semantic representation of the stimulus words. However, most studies of syntax have focused only on identifying areas correlated with syntactic processing load. One possible reason for this discrepancy is that representing syntactic structure in an embedding space such that it can be used to model brain activity is a non-trivial computational problem. Another possible reason is that it is unclear if the low signal-to-noise ratio of neuroimaging tools such as functional Magnetic Resonance Imaging (fMRI) can allow us to reveal the correlates of complex (and perhaps subtle) syntactic representations. In this study, we propose novel multi-dimensional features that encode information about the syntactic structure of sentences.

Personal use of this material is permitted. Abstract--Autonomous driving systems have achieved significant advances, and full autonomy within defined operational design domains near practical deployment. Expanding these domains requires addressing safety assurance under diverse conditions. Information sharing through vehicle-to-vehicle and vehicle-to-infrastructure communication, enabled by a Dynamic Map platform built from vehicle and roadside sensor data, offers a promising solution. Real-world experiments with numerous infrastructure sensors incur high costs and regulatory challenges. Conventional single-host simulators lack the capacity for large-scale urban traffic scenarios. This paper proposes D-A WSIM, a distributed simulator that partitions its workload across multiple machines to support the simulation of extensive sensor deployment and dense traffic environments. A Dynamic Map generation framework on D-A WSIM enables researchers to explore information-sharing strategies without relying on physical testbeds. The evaluation shows that DA WSIM increases throughput for vehicle count and LiDAR sensor processing substantially compared to a single-machine setup. Integration with Autoware demonstrates applicability for autonomous driving research. I. Introduction Current autonomous driving systems are capable of operating without human input and are fully autonomous within operational design domains (ODDs).

This Cybersecurity Unicorn Aims to Reinvent Anti-Virus with AI
Anti-virus software has a hard time keeping up. Piles of new viruses come out each week, so cybersecurity unicorn Cylance is taking what it claims to be a completely new approach: artificial intelligence that learns to recognize malicious code based on an analysis of viruses from the past. It calls the new product CylancePROTECT. In an AMA on Reddit today, the company's head of reseach, Jon Miller, wrote: "Cylance was the first AI built to statically analyze and convict malware pre-execution. We definitely didn't invent AI, but we were the first to use it this way to deliver pre-execution protection. Many other products have been using machine learning, it's just that it was used to support legacy methodologies of protection/detection, using ML to identify trends so static signatures could be built, which in a world where attackers are creating individual pieces of malware to avoid signatures, results in a severe lack of efficacy, thats the problem Cylance was built to solve."
