An activity classifier system and method that classifies human activities using 2D skeleton data. The system includes a skeleton preprocessor that transforms the 2D skeleton data into transformed skeleton data, the transformed skeleton data comprising scaled, relative joint positions and relative joint velocities. The system also includes a gesture classifier comprising a first recurrent neural network that receives the transformed skeleton data, and is trained to identify the most probable of a plurality of gestures. The system also has an action classifier comprising a second recurrent neural network that receives information from the first recurrent neural networks and is trained to identify the most probable of a plurality of actions.

This disclosure is directed to an activity classifier system, for classifying human activities using 2D skeleton data. The system includes a skeleton preprocessor that transforms the 2D skeleton data into transformed skeleton data, the transformed skeleton data comprising scaled, relative joint positions and relative joint velocities. It also includes a gesture classifier comprising a first recurrent neural network that receives the transformed skeleton data, and is trained to identify the most probable of a plurality of gestures. There is also an action classifier comprising a second recurrent neural network that receives information from the first recurrent neural networks and is trained to identify the most probable of a plurality of actions.

A combination bag, includes a sling bag and a backpack with an interior space, wherein the sling bag includes: a flat-shaped and foldable bag body with a first surface and a second surface, a rigid support structure embedded within the flat-shaped bag body, symmetrically arranged along a fold line of the flat-shaped bag body; a shoulder strap attached to the flat-shaped bag body; at least two bag components positioned on the second surface of the flat-shaped bag body, for forming an independent storage compartment; and the interior space is defined by a first wall, a second wall opposite the first wall, and a continuous side wall connecting the first and second walls; wherein the first wall has an area approximately equal to that of the flat-shaped bag body, and flat-shaped bag body is detachably fixed and close contacted with the first wall by a connecting component.

A carry bag assembly that includes a first shoulder bag and a smaller second hand bag. The two bags can be carried separately as a unit. The first shoulder bag has a front surface, a rear surface, a first side surface, and a second side surface. Two bands extend from the shoulder bag that extend beyond the front surface of the shoulder bag. The second hand bag contains a first belt loop and a second belt loop. The belt loops receive the bands that extend from the shoulder bag. Mechanical connectors connecting the first band to the second band around the hand bag. This selectively locks the smaller hand bag into a fixed position against the front surface of the larger shoulder bag. The two bags can share graphics of design themes so that the two bags appear to be a single unit when attached.
