Abstract The big-data use is becoming a standard practice in the neuroimaging field through data-sharing initiatives. It important for community to realize that such open science effort must protect personal, especially facial information when raw data are shared. An ideal tool face anonymization should not disturb subsequent brain tissue extraction and further morphological measurements. Using high-resolution head images from magnetic resonance imaging (MRI) of 215 healthy Chinese, we...

The effects of eccentricity on the attentional modulation visual discrimination have been widely studied; however, substrate this complex phenomenon is poorly understood. Here, we provided a measure three networks: alerting, orienting, and executive attention. Participants ( N = 63) were tested with modified attention network test that included an additional variation; allowed us to investigate efficiency networks at near far eccentricities. Compared targets eccentricity, generally elicited...

Policy evaluation with linear function approximation is an important problem in reinforcement learning. When facing high-dimensional feature spaces, such a becomes extremely hard considering the computation efficiency and quality of approximations. We propose new algorithm, LSTD(lambda)-RP, which leverages random projection techniques takes eligibility traces into consideration to tackle above two challenges. carry out theoretical analysis provide meaningful upper bounds estimation error,...

Embedded sensing devices that are battery-operated and resource-limited increasingly utilizing recurrent neural networks (RNNs) to attain real-time perception of the complex environment. Nevertheless, majority RNNs typically handle substantial amounts time-series data, resulting in computational intensity high energy consumption. Hence, development energy-efficient RNN models is a crucial focus. This paper introduces IS-RNN, an model featuring importance-based sparsification, aimed at...

Objective: This paper aims to prompt large language models (LLMs) for clinical temporal relation extraction (CTRE) in both few-shot and fully supervised settings. Materials Methods: study utilizes four LLMs: Encoder-based GatorTron-Base (345M)/Large (8.9B); Decoder-based LLaMA3-8B/MeLLaMA-13B. We developed full (FFT) parameter-efficient (PEFT) fine-tuning strategies evaluated these on the 2012 i2b2 CTRE task. explored GatorTron-Base: (1) Standard Fine-Tuning, (2) Hard-Prompting with Unfrozen...

People with schizophrenia often show deficits in recognizing facial emotions, which contributes to poor social functioning. In this experiment we directly investigated how 20 people being treated for categorized emotional faces. a control group of healthy who had no mental illness, happy faces were classified faster than sad faces, that is, there was positive classification advantage. However, phenomenon not present inverted Compared the group, more slowly, less accuracy, and without...
