Warp2D - 2D Time Alignment Workflow (3)

• Download

2D Time Alignment We describe a new time alignment method that takes advantage of both dimensions of LC-MS data to resolve ambiguities in peak matching while remaining computationally efficient. This approach, Warp2D, combines peak extraction with a two-dimensional correlation function to provide a reliable alignment scoring function that is insensitive to spurious peaks and background noise. One-dimensional alignment methods are often based on the total-ion-current eluti...

Exclude a Attribute/Variable (1)

• Download

This simple process demonstrates how to exclude a attribute or set of attributes from an example set/data set. In particular the first "Select Attributes" filter excludes the Outlook attribute. The second filter excludes subset {Outlook, Humidity}.

Filter Wrong Predicted/Classified Samples (1)

• Download

This process demonstrates how to filter validation samples which are predicted incorrectly. Thee key operator is "Filter Examples" that is set up to "wrong_predictions"

Apply Same Preprocessing to Learning and V... (1)

• Download

This process demonstrates how to apply the same prepossessing work flow to learning data and test/validation data. Due to overview reasons the preprocessing is hidden in a Preprocessing subprocess. To perform the same preprocessing work flow on the learning and testing data, both are collected to a Collection of Data. Then the "Loop Collection" operator loops over each collection. The actual preprocessing is done inside the "Loop Collection" operator. In the example only a "Rename" is done...

• Download

This process demonstrates how to write/store/export the correlation matrix of the "Correlation Matrix" operator to an Excel file. One need to generate a Report with the "Generate Report" operator and export the Report to an Excel file.

Discard Attribute with More than x% Missin... (1)

• Download

This process loops over all attributes and calculates the fraction of missings for each attribute. If this fration is larger than the fraction defined in the first "Set Macro" operator (macro: max_unknown), the attribute will be removed from the example set.

Convert Nominal to Binominal to Numerical (1)

• Download

This is a standard preprocessing subprocess taking nominal (categorical) attributes and introduces binominal dummy attributes before those are transformed to numerical which can be then used by learning schemes like SVM or Logistic Regression.

Pivoting (1)

• Download

This process shows the basics of Pivoting. A data set with three columns is loaded and partially generated. Afterwards, the data is rotated and missings are replaced by zero.

Evaluating Multiple Models with Looped X-V... (1)

• Download

This process shows how multiple different models can be evaluated with cross validation runs. This allows for the comparison of, for example, three prediction model types (e.g., ANN, SVM and DT) all at once under a x-fold cross validation. Having said that, the process actually performs the same cross validation several times using each time a different modeling scheme. It makes use of loops, collections, subprocess selection and macros and is therefore also an interesting showcase for more ...

Setting an attribute value in a specific E... (1)

• Download

This process will first generate an artificial dataset and tag it with ids. Then a Filter Examples Operator is used to get a dataset with exactly one example identified by it's id. Then a value is set in this example. Since the change in the data will be reflected in all views of the example set, a simply copy is passed by to the process' output. If you take a look at the attributes of the example with id 5, you will find the 12 there.

Correct Attribute Type to Binominal (1)

• Download

This process will first generate some artificial data to show a commonly known problem: Some attributes have only two values, but are not correctly stored as Binominal, instead RapidMiner recognizes them as nominal. In order to use them for some special operators, we have to change this to binominal. We can achieve this by using the Nominal to Binominal operator with the the parameter transform_binominals switched off. Please take a look at the data before and after the Nominal to Binominal o...

Homology workflow (1)

• Download

There are many kinds of DNA data derived from many species in DDBJ. It makes possible to carry out the comparative study of genes of multiple species. The workflow provides a list of species and their genes that are similar to a human gene in response to a name of the human gene.
