Abstract:

An electronic circuit includes word lines; bit lines intersecting the word lines at a plurality of grid points; and resistive processing units located at the grid points. Baseline stochastic pulse input units are coupled to the word lines; differential stochastic pulse input units are coupled to the word lines; and bitline stochastic pulse input units are coupled to the bit lines. Control circuitry coupled to the pulse input units is configured to cause each of the baseline stochastic pulse input units to generate a baseline pulse train using base input data, each of the differential stochastic pulse input units to generate a differential pulse train using differential input data defining differences from the base input data, and each of the bitline stochastic pulse input units to generate a bitline pulse train using bit line input data. Neural network weights can thus be stored in the resistive processing units.

International Classification:

G06F 7/523
G06F 7/50
G06N 3/08

Abstract:

A system is provided for error resiliency in a bit serial computation. A delay monitor enforces an overall processing duration threshold for bit-serial processing all iterations for the bit serial computation, while determining a threshold for processing each iteration. At least some iterations correspond to a respective bit in an input bit sequence. A clock generator generates a clock signal for controlling a performance of the iterations. Each of iteration units perform a particular iteration, starting with a Most Significant Bit (MSB) of the input bit sequence and continuing in descending bit significant order, and by selectively increasing the threshold for at least one iteration while skipping from processing at least one subsequent iteration whose iteration-level processing duration exceeds a remaining amount of an overall processing duration for all iterations, responsive to the at least one iteration requiring more time to complete than a current value of the threshold.

G06N 3/04
G06F 17/18

Abstract:

A method for context-aware data mining of a text document includes receiving a list of words parsed and preprocessed from an input query; computing a related distributed embedding representation for each word in the list of words using a word embedding model of the text document being queried; aggregating the related distributed embedding representations of all words in the list of words to represent the input query with a single embedding, by using one of an average of all the related distributed embedding representations or a maximum of all the related distributed embedding representations; retrieving a ranked list of document segments of N lines that are similar to the aggregated word embedding representation of the query, where N is a positive integer provided by the user; and returning the list of retrieved segments to a user.

International Classification:

G06F 9/48
G06F 9/50

Abstract:

A method, apparatus, and computer program product are provided for thermal- and spatial-aware task scheduling. The method may include monitoring a temperature for each core of a central processing unit having a plurality of cores; determining, from the monitoring, a set of hotspot cores from the plurality of cores determining temperature information and distance information for each hotspot core in the set of hotspot cores relative to each of the other cores on the central processing unit; calculating a placement metric for each core of the central processing unit based at least on the determined distance information and the determined temperature information; and scheduling a task by allocating the task to one or more cores of the central processing unit according to the placement metric.
