The content of the coarsegrained monomer must be less than the upper limit of the particle size of the mineral flotation. at present, the upper limit of flotation particle size is generally 0.250.3 mm for sulfide minerals; 0.51 mm for natural sulfur; and the upper limit of particle size for coal is 12 mm muddy as much as possible.

Personal Identification Based On Acoustic Characteristics
It can be seen from the presented results that frr and far are easier to balance in the case of ann than in the case of the bayesian classifier. however, in identification mode, the bayesian classifier gives fewer errors (eer 0.0053 versus eer 0.0266). this is first due to the small number of training samples (eight examples per subject).
This is true for binary classifiers, and the problem is compounded when computing multiclass f1scores such as macro, weighted or microf1 scores. in the multiclass case, different prediction errors have different implication. predicting x as y is likely to have a different cost than predicting z as w, as so on.
A Detailed Case Study On Multilabel Classification
In this blog post we will talk about solving a multilabel classification problem using various approaches like using onevsrest, binary relevance and classifier.
But if you sand it to a higher grit, it tends to burnish the surface and limits the absorption of finish. the result is a lighter color that more closely matches the face grain. so if you plan on sanding the project to 180 grit, i would sand the end grain to about 320. that will.
A welltrained classifier has to have only true positives. the confusion matrix of the trained svm with the testing data of 1068 samples is shown in fig. 10 with true labels versus predicted labels. the true labels are aluminium, copper, mdf and mild steelrusted respectively and this order applies to predicted labels as well.

The problem of induction and machine learning. russell, the limits of empiricism, p. 1 (emph. added) and after these a longish but varying sequence of copper balls; or we may so adjust it that, out of each hundred steel balls, 10 balls are blue, 20 green, 30 red, and 40 yellow: this would be a statistical law.
