Abstract: Disclosed herein are systems and methods to efficiently execute predictions models to identify future values associated with various nodes. A server retrieves a set of nodes and generates a primary prediction model using data aggregated based on all nodes. The server then executes various clustering algorithms in order to segment the nodes into different clusters. The server then generates a secondary (corrective) prediction model to calculate a correction needed to improve the results achieved by executing the primary prediction model for each cluster. When a node with unknown/limited data and attributes is identified, the server identifies a cluster most similar the new node and further identifies a corresponding secondary prediction model. The server then executes the primary prediction model in conjunction with the identified secondary prediction model to populate a graphical user interface with an accurate predicted future attribute for the new node.

Abstract: A method and system for facilitating payment transactions is provided. A server receives a transaction scheduling request from a first user device for scheduling a payment transaction from a first payment account associated with a first user to a second payment account associated with a second user. The payment transaction is scheduled for a first time instance. Upon successful scheduling of the payment transaction, a one-time password for authenticating the scheduled payment transaction is communicated to the first user. The server receives a payment transaction request corresponding to the scheduled payment transaction from a second user device associated with the second user to approve the scheduled payment transaction. The scheduled payment transaction is approved upon successfully receiving the one-time password from the second user device.
