Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.Details+
Jaw crusher is a main type of rock crusher used to crush minerals or stones into smaller sizes. It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.Details+
The compound crusher is used to crush a variety of medium hard ores, such as limestone, clinker,coal and other ores, which can be widely used in mining, metallurgy, refractory, cement, coal,glass, ceramics, electric power and other industries, and is one of the commonly used equipment in the crushing production line and the sand making production line. This series of crusher is a new product based on our company's PEL vertical compound crusher and optimized with domestic and foreign fine crushing technology. Its performance has reached the domestic advanced level. It is mainly for all kinds of ore with compressive strength not exceeding 200MPa and water content less than 15%.Details+
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.Details+

Mar 17, 2021 · Within 24 hours the trainable classifier will process the seed data and build a prediction model. The classifier status is In progress while it processes the seed data. When the classifier is finished processing the seed data, the status changes to Need test items. You can now view the details page by choosing the classifierMore Details
Aug 18, 2016 · Classifier : The algorithm, the core of your machine learning process. It can be an SVM, Naive bayes or even a neural network classifier. Basically it's a big "set of rules" on how you want to classify your input. Model : It is what you get once you have finished training your classifier, it's the resulting object of the training phaseMore Details
Apr 27, 2011 · If your training set is small, high bias/low variance classifiers (e.g., Naive Bayes) have an advantage over low bias/high variance classifiers (e.g., kNN), since the latter will overfit. But low bias/high variance classifiers start to win out as your training set grows (they have lower asymptotic error), since high bias classifiers aren’t powerful enough to provide accurate modelsMore Details
Dec 14, 2020 · A classifier is the algorithm itself – the rules used by machines to classify data. A classification model, on the other hand, is the end result of your classifier’s machine learning. The model is trained using the classifier, so that the model, ultimately, classifies your data. There are both supervised and unsupervised classifiersMore Details
Classifier comparison. ¶. A comparison of a several classifiers in scikit-learn on synthetic datasets. The point of this example is to illustrate the nature of decision boundaries of different classifiers. This should be taken with a grain of salt, as the intuition conveyed by these examples does not necessarily carry over to real datasetsMore Details
Jun 11, 2018 · Classification is the process of predicting the class of given data points. Classes are sometimes called as targets/ labels or categories. Classification predictive modeling is the task of approximating a mapping function (f) from input variables (X) to …More Details
Oct 25, 2020 · For example, if a model correctly identifies whether or not a player will get drafted into the NBA 88 times out of 100 possible times then the accuracy of the model is: Accuracy = (88/100) * 100% = 88%. The higher the accuracy, the better a classification model is able to predict outcomes. Similarities Between Regression and ClassificationMore Details
Mar 28, 2017 · So what are classification models? A classification model attempts to draw some conclusion from observed values. Given one or more inputs a classification model will try to predict the value of oneMore Details
What is the difference between a classifier and a model? Essentially, the terms “classifier” and “model” are synonymous in certain contexts; however, sometimes people refer to “classifier” as the learning algorithm that learns the model from the training data. To makes things more tractable, let’s define some of the key terminology:More Details
Usually these are the ones on which a classifier is uncertain of the correct classification. This can be effective in reducing annotation costs by a factor of 2-4, but has the problem that the good documents to label to train one type of classifier often are not the good documents to label to train a different type of classifierMore Details
Jul 21, 2015 · In order to illustrate the problem of chosing a classification model consider some simulated data, A first strategy is to split the dataset in two parts, a training dataset, and a testing dataset. The two datasets can be visualised below, with the training dataset on top, and the testing dataset below. We can consider a simple classification treeMore Details
Aug 19, 2020 · Given recent user behavior, classify as churn or not. From a modeling perspective, classification requires a training dataset with many examples of inputs and outputs from which to learn. A model will use the training dataset and will calculate how to best map examples of input data to specific class labelsMore Details
Jun 11, 2019 · Regression vs Classification visual Regression Models. Of the regression models, the most popular two are linear and logistic models. A basic linear model follows the famous equation y=mx+b , but is typically formatted slightly different to:. y=β₀+β₁x₁+…+βᵢxᵢMore Details
2. Model evaluation procedures ¶. Training and testing on the same data. Rewards overly complex models that "overfit" the training data and won't necessarily generalize. Train/test split. Split the dataset into two pieces, so that the model can be trained and tested on different data. Better estimate of out-of-sample performance, but still aMore Details
