Systems, devices, and methods are provided for training and/or inferencing using a list ordering model. A list ordering model, such as a Markov chain, may be trained using a plurality of lists with location metadata in common, wherein a first list of the plurality comprises items and corresponding competition timestamps. A list ordering model may accept, as an input, a plurality of items, and determine, as an output, an order for the plurality of items. Recommendations may be generated based on the determined order.

In-store navigation using list ordering models

Systems, devices, and methods are provided for interacting with item lists via lock screen notifications. In at least one embodiment, a user performs a computer-based action on a notification that is accessible to a user while a device is in a locked state and the computer-based action is used to perform an operation supported by an item list, without requiring the user to perform an authentication and/or authorization to unlock the device.
