A predictive modeling method may include determining a time interval of time-series data; identifying one or more variables of the data as targets; determining a forecast range and a skip range associated with a prediction problem represented by the data; generating training data and testing data from the time-series data; fitting a predictive model to the training data; and testing the fitted model on the testing data. The forecast range may indicate a duration of a period for which values of the targets are to be predicted. The skip range may indicate a temporal lag between the time period corresponding to the data used to make predictions and the time period corresponding to the predictions. The skip range may separate input data subsets representing model inputs from subsets representing model outputs, and separate test data subsets representing model inputs from subsets representing validation data.

Systems for time-series predictive data analytics, and related methods and apparatus

Disclosed herein are methods and systems to generate and revise a workflow that utilizes machine learning model nodes and other analytical nodes to analyze data and generate a decision via allowing a user to interact with input elements of a graphical user interface. The methods and systems use a processor to provide, for rendering by a user device, a graphical user interface comprising at least a first graphical indicator corresponding to a computer model node within workflow code and a second graphical indicator corresponding to a decision node within the workflow code, the computer model node visually connected with the decision node; and in response to receiving, via a user interacting with the graphical user interface, an additional node corresponding to at least one analytical protocol, revise the workflow code, by adding the analytical protocol before an execution of the decision node.

Methods and systems for integrated design and execution of machine learning models

A predictive modeling method may include obtaining a fitted, first-order predictive model configured to predict values of output variables based on values of first input variables; and performing a second-order modeling procedure on the fitted, first-order model, which may include: generating input data including observations including observed values of second input variables and predicted values of the output variables; generating training data and testing data from the input data; generating a fitted second-order model of the fitted first-order model by fitting a second-order model to the training data; and testing the fitted, second-order model of the first-order model on the testing data. Each observation of the input data may be generated by (1) obtaining observed values of the second input variables, and (2) applying the first-order predictive model to corresponding observed values of the first input variables to generate the predicted values of the output variables.

Systems for second-order predictive data analytics, and related methods and apparatus

Methods for detection of anomalous data samples from a plurality of data samples are provided. In some embodiments, an anomaly detection procedure that includes a plurality of tasks is executed to identify the anomalous data samples from the plurality of data samples.

Methods for detecting and interpreting data anomalies, and related systems and devices

Systems and techniques for predictive data analytics are described. In a method for selecting a predictive model for a prediction problem, the suitabilities of predictive modeling procedures for the prediction problem may be determined based on characteristics of the prediction problem and/or on attributes of the respective modeling procedures. A subset of the predictive modeling procedures may be selected based on the determined suitabilities of the selected modeling procedures for the prediction problem. A resource allocation schedule allocating computational resources for execution of the selected modeling procedures may be generated, based on the determined suitabilities of the selected modeling procedures for the prediction problem. Results of the execution of the selected modeling procedures in accordance with the resource allocation schedule may be obtained. A predictive model for the prediction problem may be selected based on those results.

Systems and techniques for predictive data analytics

A method for determining the predictive value of a feature may include: (a) performing predictive modeling procedures associated with respective predictive models, wherein performing each modeling procedure includes fitting the associated model to an initial dataset representing an initial prediction problem; (b) determining a first accuracy score of each of the fitted models, representing an accuracy with which the fitted model predicts an outcome of the initial prediction problem; (c) shuffling values of a feature across observations included in the initial dataset, thereby generating a modified dataset representing a modified prediction problem; (d) determining a second accuracy score of each of the fitted models, representing an accuracy with which the fitted model predicts an outcome of the modified prediction problem; and (e) determining a model-specific predictive value of the feature for each of the fitted models based on the first and second accuracy scores of the fitted model.
