Abstract: A single light emitting diode (LED) structure includes an array of spaced discrete light emitting zones separated by isolation areas. Each emitting zone includes an epitaxial structure configured to emit an emitting light having a particular wavelength over an effective emission area. In addition, the effective emission area for each emitting zone can be geometrically defined and electrically configured to provide a desired light intensity. For example, each effective emission area can have a selected size and spacing depending on the application and light intensity requirements. Each emitting zone also includes a wavelength conversion member on its effective emission area configured to convert an emitting wavelength of the emitting light to a different color. The single (LED) structure can include multiple colors at different zones to produce a desired spectra or design.

Abstract: Techniques and systems are provided for predicting answers in response to one or more input queries. For instance, text from a corpus of text can be processed by a reader to generate one or multiple question and answer spaces. A question and answer space can include answerable questions and the answers associated with the questions (referred to as “question and answer pairs”). A query defining a question can be received (e.g., from a user input device) and processed by a retriever portion of the system. The retriever portion of the system can retrieve an answer to the question from the one or more pre-constructed question and answer spaces, and/or can determine an answer by comparing one or more answers retrieved from the one or more pre-constructed question and answer spaces to an answer generated by a retriever-reader system.

Abstract: A virtual camera captures first images of a three-dimensional (3D) digital representation of a visual asset from different perspectives and under different lighting conditions. The first images are training images that are stored in a memory. One or more processors implement a generative adversarial network (GAN) that includes a generator and a discriminator, which are implemented as different neural networks. The generator generates second images that represent variations of the visual asset concurrently with the discriminator attempting to distinguish between the first and second images. The one or more processors update a first model in the discriminator and/or a second model in the generator based on whether the discriminator successfully distinguished between the first and second images. Once trained, the generator generates images of the visual asset based on the first model, e.g., based on a label or an outline of the visual asset.

Abstract: A method for tracing an error of a logic system design includes obtaining an assertion failure of a combinational cone of the logic system design, the combinational cone including a plurality of sub-cones; and obtaining machine learning models of the sub-cones. Each sub-cone represents a sub-circuitry of the logic system design and has one or more input signals and an output signal. The assertion failure indicates an actual signal value of the combinational cone at a current clock cycle being different from an expected output value at the current clock cycle. The method also includes: performing backtracing on the sub-cones according to the assertion failure, the machine learning models of the sub-cones, and dynamic backtracing sensitivities corresponding to the sub-cones, to obtain a backtracing result; and outputting one or more target sub-cones as candidate root causes of the assertion failure according to the backtracing result.
