Abstract: Certain aspects of the present disclosure provide techniques and apparatus for quantized machine learning. A quantized input matrix is accessed at a layer of a neural network, and a first interim value is generated in an accumulator by performing matrix multiplication, using the accumulator, of the quantized input matrix and a quantized weight matrix associated with the layer of the neural network. The first interim value is normalized based at least in part on one or more leading sign bits of the first interim value, and the normalized first interim value is dequantized. A second interim value is generated by applying a rounded right-shift operation to the dequantized normalized first interim value, and activation data is generated by applying an activation function to the second interim value.

Abstract: An activity and volume sensing beverage container cap system for a beverage container including a cap that couples with the beverage container, a processor, a timer and at least one activity level sensor, such as an inclinometer, coupled with the processor. The activity level sensor detects container orientation. When the container is tilted, the timer measures an amount of time in an orientation. Based on the current and previous orientation and the amount of time the container is in different orientations, the processor determines an amount of time of activity of the user, and a level of activity of the user, such as number of steps or moves per time. The inclinometer is also used to determine the amount of volume dispensed from the container when tilted over a threshold indicative of drinking. Thus one inclinometer may be utilized as both to determine activity level and volume of fluid dispensed.
