Abstract: An optical transmitter can generate probabilistically shaped quadrature amplitude modulation (PS-QAM) signaling for transmission over a fiber to a destination without optical amplification. The single fiber can transmit the PS-QAM signaling using dense wavelength division multiplexing having a relatively large number of channels that are closely spaced. A coherent receiver can receive the PS-QAM signaling for decoding without implementing chromatic dispersion compensation.

Abstract: One or more systems and/or methods of generating a query-goal-mission structure for a set of queries are provided. A set of queries may be evaluated to identify query information for the queries within the set of queries. The queries may be evaluated as query pairs to determine common goal probabilities (e.g., likelihood two queries correspond to a particular goal, such as to identify vacation planning information) for the query pairs. Responsive to the common goal probabilities for the query pairs exceeding a goal probability threshold, the query pairs may be grouped into goal clusters. The goal clusters may be evaluated as goal cluster pairs to determine common mission probabilities. Responsive to the common mission probabilities for the goal cluster pairs exceeding a mission probability threshold, the goal clusters may be grouped into mission clusters. The mission clusters and the goal clusters may be utilized to generate a query-goal-mission structure.

Abstract: One or more client devices, systems, and/or methods of improving mobile searches are provided. A feature (e.g., “snow boots”), generated on a client device, is identified. The feature is evaluated to identify a goal (e.g., finding snow boots) associated with the feature. A mission (e.g., finding outdoor apparel), associated with the goal, is identified. A query (e.g., “outdoor stores near Akron”) associated with a second goal (e.g., find outdoor apparel store) associated with the mission is identified using a model generated utilizing a machine learning method trained using a query-goal-mission structure. A query recommendation (e.g., “outdoor apparel store”) comprising the query is presented to the user. A user satisfaction metric, associated with the query, the query recommendation, a result generated by the query recommendation, etc. is determined based upon user interaction with the query recommendation and the result. The model may be tuned based upon the user satisfaction metric.

Abstract: The present teaching relates to method, system, and programs for training a ranking model for ranking content items. In one example, a set of content items is obtained. A plurality types of online user activities performed with respect to the set of content items are obtained. For each of the set of content items, a plurality of user engagement scores are determined. Each of the plurality of user engagement scores is determined based on a corresponding one of the plurality types of online user activities. For each of the set of content items, an aggregated score is calculated based on the plurality of user engagement scores to generate aggregated scores. A ranking model is trained based on the aggregated scores.

Abstract: An optical film and a display assembly applying the optical film are provided. The optical film may comprise a plurality of truncated tapered units embedded in a material layer for transmitting a light emitted from the display unit by reflecting the light through a reflection surface between the truncated tapered units and the material layer, wherein a ratio of the area of a first end surface where the light emerges from each truncated tapered unit and the area of a second end surface where the light is incident into each truncated tapered may be between 0.2 and 0.6. Furthermore, a light absorbing layer may be formed on a light output side of the optical film for absorbing ambient light.
