classification× 1628
An instance of supervised learning that identifies the category or categories which a new instance of dataset belongs.
scikit-learn× 1094

nlp× 964
a field of computer science, artificial intelligence, and linguistics concerned with the interactions between computers and human (natural) languages. As such, NLP…
data-mining× 862
An activity that seeks patterns in large, complex data sets. It usually emphasizes algorithmic techniques, but may also involve any set of related skills, applications, or methodologies with that goal…
dataset× 769
a collection of data, often in tabular or matrix form.
This tag is NOT intended for data requests ("where can I find a dataset about ...") --> see OpenData
clustering× 754
the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than t…
regression× 734
Techniques for analyzing the relationship between one (or more) "dependent" variables and "independent" variables.
cnn× 641
Convolutional Neural Networks (CNN, also called ConvNets) are a tool used for classification tasks and image recognition. The name giving first step is the extraction of features from the input data.…
pandas× 609
a python library for Panel Data manipulation and analysis, e.g. multidimensional time series and cross-sectional data sets commonly found in statistics, experimental science results, econome…
lstm× 589
LSTM stands for Long Short-Term Memory. When we use this term most of the time we refer to a recurrent neural network or a block (part) of a bigger network.
statistics× 543
a scientific approach to inductive inference and prediction based on probabilistic models of the data. By extension, it covers the design of experiments and surveys to gather data for th…
feature-selection× 455
Methods and principles of selecting a subset of attributes for use in further modelling
text-mining× 436
Refers to a subset of data mining concerned with extracting information from data in the form of text by recognizing patterns. The goal of text mining is often to classify a given document into one of…
data× 406
Questions mostly concerned with managing data, without focus on pre-processing or modelling.
random-forest× 404
a machine-learning classifier based on choosing random subsets of variables for each tree and using the most frequent tree output as the overall classification.
bigdata× 387
the term for a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. The ch…
data-cleaning× 384
a preliminary step to statistical analysis in which the data-set is edited to correct errors and to put it into a form suitable for processing by statistical software.
visualization× 377
Constructing meaningful and useful graphical representations of data. (If your question is only about how to get particular software to produce a specific effect, then it is likely not on topic here.)…
image-classification× 376
For questions about image classification: a decision problem where an algorithm must decide to which class ('cat', 'chair', 'tree') an input image belongs.
linear-regression× 371
Techniques for analyzing the relationship between one (or more) "dependent" variables and "independent" variables.
decision-trees× 366
a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one wa…
