摘要： A time-series-data feature extraction device includes: a data processing unit that processes a received unevenly spaced time-series-data group into an evenly spaced time-series-data group including omissions and an omission information group indicating presence or absence of omissions, based on a received input time-series data length and a received minimum observation interval; a model learning unit that learns a weight vector of each layer of a model with a difference between an element not missing in a matrix of the evenly spaced time-series-data group including omissions and an element of an output result of an output layer of the model being taken as an error, and stores the weight vector as a model parameter in a storage unit, the difference being; and a feature extraction unit that receives time-series data of a feature extraction target, calculates a value of the intermediate layer of the model with use of the model parameter stored in the storage unit by inputting the received time-series data of the feature extraction target into the model, and outputs the calculated value of the intermediate layer as a feature that represents temporal changes in data.

摘要： A flow cell (2) includes a plate-shaped body 21 that is almost rectangular in a plan view, an introduction portion (22) that is made of a concave portion formed in the upper surface of the body (21), a channel (23) that is formed inside the body (21) and has one end connected to the lower end of the introduction portion (22), and a delivery portion (24) that is made of a concave portion formed in the body (21) and has the lower end connected to the other end of the channel (23). The introduction portion (22) is formed to cause the meniscus of a liquid introduced from an opening to apply, to the liquid, a positive pressure or a negative pressure whose absolute value is smaller than that of a negative pressure applied to the liquid introduced into the channel (23) by the meniscus of the liquid. The channel (23) is formed to cause the meniscus of the liquid introduced into the channel (23) to apply a negative pressure to the liquid. This invention provides a flow cell and a liquid feed system capable of more easily controlling feed of a trace amount of liquid.

摘要翻译： 流通池（2）包括在平面图中几乎为矩形的板状主体21，形成在主体（21）的上表面中的凹部形成的导入部（22），通道（ 23），其形成在所述主体（21）的内部，并且一端与所述导入部（22）的下端连接;以及输送部（24），其由形成在所述主体（21）中的凹部形成， 其下端连接到通道（23）的另一端。 引入部分（22）形成为使从开口引入的液体的弯月面向液体施加绝对值小于施加到引入到液体中的液体的负压的正压力或负压 通道（23）由液体的弯液面。 通道（23）被形成为使得引入通道（23）的液体的弯月面向液体施加负压。 本发明提供一种能够更容易地控制微量液体的进料的流动池和液体进料系统。
