Provided herein is a computer system for creating driving challenges for drivers. The computer system may include a processor in communication with a memory device, and the processor may be programmed to: (i) receive driving data associated with a driver, (ii) generate a first model that models the driving data associated with the driver, (iii) calculate a predicted driving score for the driver based at least in part upon the first model, (iv) generate a second model that predicts a confidence of the predicted driving score, (v) calculate a confidence value of the predicted driving score, wherein the confidence value is a squared error of the predicted driving score, and (vi) generate at least one driving challenge for the driver based at least in part upon the predicted driving score and the confidence value for that predicted driving score.

Skill measurement systems and methods include interaction pairs and an interaction uncertainty. The interaction pairs are pairwise matches corresponding to instances of interactions between players. The interaction uncertainty variable corresponds to the instance of interaction and is based in part on the uncertainties of a player, player team, and/or gameplay aspects. The interaction pairs and interaction uncertainty are used to more accurately determine a skill rating of a player based in part on interaction data among gameplay data from a gameplay session of a video game.

A self-managing database system includes a metrics collector to collect metrics data from one or more databases of a computing system and an anomaly detector to analyze the metrics data and detect one or more anomalies. The system includes a causal inference engine to mark one or more nodes in a knowledge representation corresponding to the metrics data for the one or more anomalies and to determine a root cause with a highest probability of causing the one or more anomalies using the knowledge representation. The system includes a self-healing engine, to take at least one remedial action for the one or more databases in response to determination of the root cause.

Systems and methods are provided for analyzing messages generated by a plurality of computing devices associated with a plurality of users in a messaging system to generate training data to train a machine learning model to determine a probability that a media content item was generated inside an enclosed location or outside, receiving a media content item from a computing device, analyzing the media content item using the trained machine learning model to determine a probability that the media content item was generated inside an enclosed location or outside, determining, based on the probability generated by the trained machine learning model, that the media content item was generated inside an enclosed location, and determining an inside temperature associated with the venue based on messages generated by a plurality of computing devices in a messaging system comprising media content items and temperature information for the venue or a similar venue type.

Provided is a data amount sufficiency determination device capable of determining the sufficiency of the data amount of learning data with higher accuracy.

A data amount sufficiency determination device according to the present disclosure includes a time series data acquisition unit to acquire time series data, a data division unit to divide the time series data into a plurality of pieces of substring data, a data set generation unit to generate a plurality of substring data sets that are sets of substring data, a feature amount calculation unit to calculate a feature amount of the substring data, a probability distribution generation unit to generate probability distribution of the feature amount for each substring data sets, and a determination unit to determine whether or not the probability distribution has converged.

Provided is a prediction system that predicts whether a prescribed event will occur in a device, without being affected by differences among individual devices. The prediction system comprises: a data acquisition unit which acquires operation data representing the operation status of a device; a probability density estimation unit which estimates the probability density of the operation data; and an abnormality prediction unit which predicts whether an abnormality will occur in the device on the basis of the probability density estimation results of the operation data and a prediction model.

In implementations of systems for estimating terminal event likelihood, a computing device implements a termination system to receive observed data describing values of a treatment metric and indications of a terminal event. Values of the treatment metric are grouped into groups using a mixture model that represents the treatment metric as a mixture of distributions. Parameters of a distribution are estimated for each of the groups and mixing proportions are also estimated for each of the groups. In response to receiving a user input requesting an estimate of a likelihood of the terminal event for a particular value of the treatment metric, the termination system generates an indication of the estimate of the likelihood of the terminal event for the particular value based on a distribution density at the particular value for each of the groups and a probability of including the particular value in each of the groups.

Systems and methods for automatically building a machine learning model are disclosed. A plurality of variables is displayed via a graphical user interface (GUI). A target variable and a first independent variable are identified from the plurality of variables. A parameter associated with the machine learning model is identified. Collected data is received via the GUI. A first machine learning model is built using as inputs, the parameter and the collected data associated with the first independent variable and the target variable. A change is made to at least a portion of the inputs used to build the first machine learning model. A second machine learning model is built based on the change. A prediction accuracy of the first machine learning model is compared to the prediction accuracy of the second machine learning model. Either the first or second machine learning model is selected based on the prediction accuracy.
