Overview of SPIRAL. SPIRAL includes two consecutive modules: SPIRAL-integration (upper right) and SPIRAL-alignment (bottom right). SPIRAL-integration takes combined gene expressions and separated graphs, constructed by spatial coordinates of spots for each sample, as input and learns the disentangled embeddings as biological …

slurry sediment to the bottom of the classifier and are dragged up by a rotating spiral to produce an output referred as underflow, which is sent to a further processing stage. The part of the slurry containing fine particles of solids that did not sediment, flows freely through the borders of the classifier and is referred as overflow [8]. The ...

Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...

The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.

First, there is a LinearSVC() classifier. As the name suggests, this classifier uses only a linear kernel. In LinearSVC() classifier, we don't pass the value of the kernel since it is used only for linear classification purposes. Scikit-Learn provides two other classifiers — SVC() and NuSVC() which are used for classification purposes.
