22-01-2021· 2.4. Quality Classification. To classify the quality of injection-molded parts, we converted the measured qualities (such as geometrical width) into multiple grades. As indicated in Equation (6), we aggregated the data into N g grades evenly spaced between the minimum and maximum values in W. ΔW represents the bandwidth of each grade.
The issue is that some classes can have many members, i.e. many instances belong to it. Obviously if 50% of all data points belong to one class and my final classifier is 50% correct overall, I have gained nothing. I could have just as well made a trivial classifier …

10-07-2020· Evaluating with Multiclass Classification Model It can be seen that the Target output (Quality) against other features will not plot a perfect fit line hence we should consider using a classification algorithm (Random Forest). The output shows that we can classify it based on its unique rating of 3,4,5,6,7,8.

14-05-2018· Event classification was automated using a restricted Boltzmann machine (RBM), a type of artificial neural network, trained on 2-D images of the suspended-sediment discharge (hysteresis) plots. Expansion of the hysteresis patterns to 14 classes allowed for new insight into drivers of the sediment-discharge event dynamics including spatial scale, antecedent conditions, hydrology, and …
"The Matthews correlation coefficient is used in machine learning as a measure of the quality of binary (two-class) classifications. It takes into account true and false positives and negatives and is generally regarded as a balanced measure which can be used even if the classes are of very different sizes.
