国外研究团队对意识(认知)评估听觉范式的新型改善方法

利用Oddball(新异刺激)听觉范式(后文中部分内容译为:反常听觉范式)进行意识情况识别已成为脑机接口(BCI)领域的一个重要研究课题。对于注意力有限的患者来说,尽可能缩短获取评估所需的足够数据的时间是至关重要的。本研究旨在通过测试不同的设定和刺激方法,减少Oddball听觉范式的评估时间。一类范式使用被试主体自己的名字作为偏差声音刺激。另一类范式使用标准正弦波声音进行刺激。在一组9名健康被试人员中,在4种不同的Oddball听觉范式条件下记录被试者的脑电图(EEG)活动。为了进行对比,我们计算了每个范式下的P300曲线下的面积。首先,我们证明了含有受试者名字的范式下比正弦音范式下产生了更大面积的P300区域。更重要的是,我们发现与标准听觉范式相比,“名称范式”需要更少的试验刺激次数就能获得类似的结果。这意味着与使用正弦波相比,听觉范式的执行时间是可以被减少的。

ERNIE 3.0 Titan:最强中文预训练模型

本文介绍了一个中文大语言模型。作者提出了名为ERNIE 3.0的统一框架,用于预训练大规模知识增强模型,并训练了一个具有 100 亿个参数的模型。 ERNIE 3.0 在各种 NLP 任务上的表现优于最先进的模型。为了探索扩展 ERNIE 3.0 的性能,作者在PaddlePaddle平台上训练了具有多达2600亿个参数的百亿参数模型 ERNIE 3.0 Titan。此外,作者设计了一个自监督的对抗损失和一个可控的语言建模损失,使ERNIE 3.0 Titan 生成可信且可控的文本。为了减少计算开销和碳排放,作者为 ERNIE 3.0 Titan 提出了一个在线蒸馏框架,其中教师模型将同时教授学生和自我训练。ERNIE 3.0 Titan是迄今为止最大的中文密集预训练模型。实证结果表明,ERNIE 3.0 Titan在 68 个NLP数据集上的表现优于最先进的模型。

React极简教程: Hello,World!React简史React安装Hello,World

A programming paradigm is a fundamental style of computer programming. There are four main paradigms: imperative, declarative, functional (which is considered a subset of the declarative paradigm) and object-oriented. Declarative programming : is a programming paradigm that expresses the logic of a computation(What do) without describing its control flow(How do). Some well-known examples of declarative domain specific languages (DSLs) include CSS, regular expressions, and a subset of SQL (SELECT queries, for example) Many markup languages such as HTML, MXML, XAML, XSLT… are often declarative. The declarative programming try to blur the distinction between a program as a set of instructions and a program as an assertion about the desired answer. Imperative programming : is a programming paradigm that describes computation in terms of statements that change a program state. The declarative programs can be dually viewed as programming commands or mathematical assertions. Functional programming : is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. In a pure functional language, such as Haskell, all functions are without side effects, and state changes are only represented as functions that transform the state. ( 出处:维基百科)

NAACL同传Workshop:千言 - 机器同传

同声传译结合了机器翻译(MT)、自动语音识别(ASR)和文本语音合成(TTS)等人工智能技术,在国际会议、商务谈判、新闻发言、法律诉讼和医学交流等众多场景都有广泛的应用,已发展成为一个前沿的研究领域。作为一个新兴的跨学科领域,同声传译未来将面临更多挑战。 Simultaneous translation, which performs translation concurrently with the source speech, is widely useful in many scenarios such as international conferences, business negotiations, press releases, legal proceedings and medical communications. It combines the AI technologies of machine translation (MT), automatic speech recognition (ASR) and text-to-speech synthesis (TTS),and is becoming a cutting-edge research field. As an emerging interdisciplinary field, Simultaneous translation will face more challenges in the future.
