Abstract: A method for generating a chain of machine learning models includes: receiving a data sample including one or more features and a target property; identifying, by a processor of a computer system, an unsupervised machine learning model trained to classify data samples based on the one or more features, independently of the target property, into a plurality of clusters; classifying the data sample based on the one or more features using the unsupervised machine learning model to compute a cluster; identifying, by the processor, a supervised machine learning model corresponding to the cluster; and computing a value for the target property by supplying the data sample to the supervised machine learning model.

Abstract: A method includes receiving one or more features characterizing; a first user; one or more features characterizing a geographic region; and a selection of product offerings offered by a platform; computing specific predictions for the selection of product offerings to be adopted by the first user, each specific prediction being computed for a corresponding product offering of the selection of product offerings by: selecting a specific model for the corresponding product offering corresponding to the one or more features characterizing the geographic region, trained based on training data collected by the platform; and supplying the one or more features characterizing the first user to the specific model to compute the specific prediction; and computing an aggregated prediction from adopting the selection of product offerings based on the specific predictions, the aggregated prediction being smaller than the sum of the specific predictions for the selection of product offerings.

Abstract: A method and system for displaying investment account information mimicking outcomes of a game-of-chance on a game-of-chance graphical user interface generated by a return on investment game-of-chance interface application executed on an electronic device. The method includes initializing a session of the game-of-chance and receiving preexisting investment account information including an initial investment value, past returns on investment value, and a total preexisting investment account balance. The method includes calculating a game-of-chance result for each round of the plurality of rounds such that the game-of-chance result for each round of the plurality of rounds are amounts that converge towards a total winnings value of the session equivalent to the preexisting investment account information. The method includes displaying on the electronic device via a game-of-chance graphical user interface after each round of the plurality of rounds the game-of-chance result associated with said round.

Abstract: A method and system for revealing investment account information including past returns of one or more of the user's preexisting investments is provided. The method and system include providing a query to one or more databases to access and acquire investment account information of the user's preexisting investments. The method and system include obtaining, in response to the query, the investment account information. The method and system also include populating the investment account information to be accessed by a return on investment game-of-chance interface application. The method and system additionally include revealing the investment account information as though the past returns of one or more of the user's preexisting investments were the result of a game-of-chance played by the user on a game-of-chance user interface by operation of the return on investment game-of-chance interface application.
