Abstract: Continual learning techniques are described for extending the capabilities of a base model, which is trained to predict a set of existing or base classes, to generate a target model that is capable of making predictions for both the existing or base classes and additionally for making predictions for new or custom classes. The techniques described herein enable the target model to be trained such that the model can make predictions involving both base classes and custom classes with high levels of accuracy.

Abstract: An actuation location for actuation of a first source coupled to a first marine survey vessel relative to a position of a second marine survey vessel towing a receiver to enhance illumination of a subsurface location can be determined based on a survey route of the second marine survey vessel and a priori data of the subsurface location. The first marine survey vessel can be navigated along a survey route of the first marine survey vessel to the actuation location during a marine survey by changing at least a cross-line position or an in-line position of the first marine survey vessel relative to the survey route of the second marine survey vessel.

Abstract: A method for correction of a sea surface state can include receiving geophysical data from a seismic survey, wherein the seismic survey utilizes a plurality of receivers disposed in a body of water and at least one source in the body of water, actuated at a plurality of shot points. The method can include identifying, in the geophysical data, a wavefield based on the actuation of the at least one source, and determining, based on the identified wavefield, a sea surface state at the at least one source at one of the plurality of shot points.

Abstract: The present invention extends to methods, systems, and computer program products for automated statistical analysis job chunking. A computer system provides an interface for a user to submit job requests which pair a script with a query. The computer system and a batch module interoperate with one another to process the job requests and return the job results to the user. The computer system can query the batch module to understand computational resource capability and availability. The computer system can also partition the larger parent job into smaller job chunks for the purpose of multi-threading and to facilitate concurrent parallel processing.

Abstract: A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section may be used in combination with a separate bed or beds of particulate adsorbent material. In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.

Abstract: Systems and methods for executing trades on an interconnected computer network, such as the Internet, using a catalog of protocol-independent fundamental asset trading messages, called “gestures,” that support multiple higher-level trading protocols which characterize most asset trading transactions. Trading transactions requiring protocol-dependent workflows are composed from protocol-independent gestures selected from the catalogue of gestures and then passed one at a time to an online asset trading server. The online asset trading server transitions pending quotes and trades through a series of distinct states, based on the current state, the selected protocol-independent gestures it receives and a set of state transition rules, thereby implementing the higher-level protocol-dependent workflows.
