Abstract: Techniques are disclosed for automatically creating or updating predictive models, including digital marketing forecast models. A predictive model is updated in real-time or near real-time using a stochastic gradient descent optimization method based on one or more predictive values associated with an advertising impression that is won in an online advertising auction. Each predictive value, which is obtained from the predictive model, is encoded as an argument in a uniform resource locator (URL) corresponding to the ad impression being auctioned. If and when the ad impression is won, the predictive value(s) and other information can be tracked and immediately available for updating the model using information encoded in the URL.

Abstract: Techniques are provided for automatically detecting homologies between documents based on structural characteristics. Various statistics relating to the COS structure of a PDF document are compiled. The statistics are input into a rolling hash function to generate a digital fingerprint of the document. Fingerprints from two similar documents will have small edit distances between them, and can therefore be classified similarly or provided as results to a fingerprint-based search. For example, an unclassified document may be classified in the same class as a representative document where the fingerprints of the two documents have a small edit distance between them. Since the structure of the document is used instead of the text content or renderings, it is possible to operate on encrypted documents. Further, representative elements of a particular class of documents can be selected for comparison against a target document for improved resolution of the results.

Abstract: A content aware pattern stamping tool that preserves the visual texture of an area within an image when filling the area with a pattern is provided. In one embodiment, the pattern stamping tool analyzes an area to be filled with a pattern to determine textural characteristics of the area. These textural characteristics may include reflectance and shading. Once the pattern stamping tool has determined the textural characteristics of the area, the pattern stamping tool fills the area with the pattern and applies the textural characteristics to the filled area. Through application of the textural characteristics, the pattern stamping tool generates an image that combines the pattern with the original textural characteristics of the area.

Abstract: Techniques are disclosed for secure playback of protected multimedia content on a game console using a secret-less application. An SSO model can be used for client authentication at a key server, which eliminates the need of storing or using any secret information in the client application. Further, an encrypted content key generated by a content packager using a public key can be deployed in the key URI of a playlist file, which is sent to the key server. The key server can be configured to decrypt the content key using a corresponding private key. Further, the content key and unencrypted samples are protected in the game console client application from debugging and replay attacks by using additional security checks at both the client and key server. By storing secret information remotely from the game console and using the SSO model, DRM policies can be enforced on an untrusted client application.

Abstract: Techniques are disclosed for converting a stereolithographic model into an STL data file that defines logically related components and subcomponents of an object. A user can categorize elements of an object to form logically related components and subcomponents of the object. Each element is represented by a triangle. All triangles representing each of these components and subcomponents are then reordered and listed sequentially within the STL. Each list is delimited at the beginning and end by two hidden triangles, one or both of which store unique identification values that are associated with the respective individual components. Additionally, a reference table can be added to the STL. The reference table includes instructions, operations or other information that is specifically associated with each component and subcomponent using the unique identification values. These instructions and operations enable users to have better control over 3D print quality than is possible using existing techniques.
