An electronic device may have a display system. The display system may include a waveguide, an input coupler, and a surface relief grating (SRG) structure. There are various ways to form a SRG structure. In one example, nanoimprinting may be performed on a low-index resin to form a mold for a subsequent deposition of high-index material. The high-index material conforms to the mold to form ridges for the SRG structure. A reusable mold may be formed with a plurality of ridges on a flexible substrate and coated by an anti-stick coating. The reusable mold may be coated with a high-index material that is attached to a glass substrate and cured to form a wafer-level SRG structure with high-index ridges on a glass substrate. The wafer-level SRG structure is subsequently diced. SRG structures may also be formed that include varying trough thicknesses, varying ridge thicknesses, and/or a sloped substrate.

Methods of forming holographic gratings for optical systems

Finger-wearable input assemblies for controlling an electronic device and methods for using finger-wearable input assemblies for controlling an electronic device are provided.

Product records having attributes according to various schema are normalized such that the attributes thereof conform to a canonical schema. Attributes for large numbers of product records are normalized according to a map-reduce framework in which mappers are defined but no reducers. Rules are implemented by a rule engine that is instantiated one time per VM of the map-reduce framework. Likewise, each rule may be implemented by only one object instance per rule engine instance. Generation of rules by analysts may be facilitated by defining an attribute hierarchy. A rule defined for a parent attribute may be presented as a default rule for a child attribute and either accepted or revised. Attributes may be clusters and proposed rules generated. Proposed rules may then be accepted or rejected by an analyst.

Normalization rule generation and implementation systems and methods

A method of validating rules configured to be utilized in an information extraction application, including: receiving a plurality of labeled samples in a training database; for each of the rules in the rule database: (a) determining, for each of the data points of the plurality of labeled samples in the training database to which the rule applies, whether applying the rule to the data point has a positive or negative impact on matching an output for the data point based on the rule to the assured output of the labeled sample corresponding to the data point; (b) generating positive impact information for the rule based on the positive voters; (c) generating negative impact information for the rule based on the negative voters; and (d) determining a metric for the rule based on the quantity of the negative voters and the quantity of the positive voters; ranking the rules based on the metrics corresponding to the rules; and sending to a user for refinement one or more flagged rules of the rules that have a lowest ranking of the metric. Other embodiments are provided.

Automatic rule coaching

Systems and methods are disclosed herein for rule-based item classification. The methods include receiving, by a computing device, an item record for analysis. The computing device may determine ranked lists of item types using rule-based classifiers and machine learning-based classifiers. Then, the computing device may aggregate the ranked lists of item types to generate a combined ranked list of item types.
