可感知的

In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。

Now if we accept the Kantian view that subjective apprehension is always successive and atomistic, then arguably the only thing that can make the two perceptions commensurable, is if they are perceived as so many alterations of a single underlying external world.

现在，如果我们接受Kant式对'主体性apprehension一直是续起和atomistic『原子的/孤立的』'的看法，那么可论证仅有的使得两个感知事物commensurable『可同标准度量的』是是否它们是被感知为一个单一外在世界的相同多的变化。

This thesis establishes constrained motion model and sensor model of a mobile robot to represent mobility and perceptivity, respectively, and defines the k step reachable region to describe the states that the robot may reach. We show that the calculation of the k step reachable region can be reduced from that of 2k reachable regions with the fixed motion styles to k + 1 such regions, and provide an algorithm for its calculation.

Now consider a theory of perception according to which we have direct perceptual access to ordinary objects and to many ordinary properties (properties of external objects, not sense-data, etc.). In fact, as we saw above in the analogous case of "outside-a-room scepticism," we have to make this assumption if we are to have unproblematic access to things in the counter-domain. In such a case, and in contrast to the case of house arrest, the Humean argument does apply and does, apparently, go through.

现在考虑一个感知理论，据其我们直接感知性可达常识对象和可达许多常识属性（——关于外在对象的属性，而不是感觉材料的，等），事实上，如我们上面看到的，在屋外怀疑论的类似情况中，如果我们要不成问题地可达在反区域的事物，我们不得不做这个预设，而在这样的情况中，和屋子情况比较，Hume式论证显然被使用和执行。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
