    • In one aspect, a computer-implemented method is disclosed. The computer-implemented method may include determining a sketch matrix that approximates a matrix representative of a reference dataset. The reference dataset may include at least one computer program having a predetermined classification. A reduced dimension representation of the reference dataset may be generated based at least on the sketch matrix. The reduced dimension representation may have fewer features than the reference dataset. A target computer program may be classified based on the reduced dimension representation. The target computer program may be classified to determine whether the target computer program is malicious. Related systems and articles of manufacture, including computer program products, are also disclosed.
    • 在一个方面,公开了一种计算机实现的方法。 计算机实现的方法可以包括确定近似表示参考数据集的矩阵的草图矩阵。 参考数据集可以包括具有预定分类的至少一个计算机程序。 至少基于草图矩阵可以生成参考数据集的降维表示。 缩小的维度表示可以具有比参考数据集更少的特征。 目标计算机程序可以基于简化维度表示来分类。 目标计算机程序可以被分类以确定目标计算机程序是否是恶意的。 还公开了相关系统和制造产品,包括计算机程序产品。

    • Described herein is a gas detection system (5) including a housing (10) having an inlet (20) in fluid communication with an atmosphere; an analyzer (25) within the housing (20) and configured to detect and measure a gas species in the atmosphere using a gas sensor (37); and a pneumatic system (60) contained within the housing (10) and in fluid communication with the inlet (20) to draw an air sample from the atmosphere. The pneumatic system (60) includes a pump (15); a low flow branch (65) in fluid communication with the pump (15) and having an airflow sensor (90) and a first orifice (85); and a high flow branch (70) in fluid communication with the pump (15) and having a second orifice (95). Such a system is particularly suitable for remote sampling because it prevents the high flow needed for remote sampling to be directed towards the gas sensor withstanding only low flow. Related apparatus, systems, methods and/or articles are described.
    • 这里描述了一种气体检测系统(5),包括具有与大气流体连通的入口(20)的壳体(10) 壳体(20)内的分析器(25),并且被配置为使用气体传感器(37)来检测和测量大气中的气体种类; 以及包含在所述壳体(10)内并与所述入口(20)流体连通以从大气抽出空气样本的气动系统(60)。 气动系统(60)包括泵(15); 与所述泵(15)流体连通并具有气流传感器(90)和第一孔口(85)的低流量分支(65); 以及与所述泵(15)流体连通并具有第二孔口(95)的高流量分支(70)。 这样的系统特别适用于远程采样,因为它防止远程采样所需的高流量仅通过低流量被引向气体传感器。 描述了相关装置,系统,方法和/或制品。
