  • Publication number: 20250139438
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining a size of a training data set for training a machine learning model. In one aspect, the size is determined using a shrinking estimate that estimates how much training data is needed to train a smaller machine learning model to achieve the same performance as a larger machine learning model.

  • Patent number: 11657231
    Abstract: The present disclosure relates to a response analysis system that employs a small-data training dataset to train a neural network that accurately performs domain-agnostic opinion mining. For example, in one or more embodiments, the response analysis system trains a response classification neural network using part of speech information (e.g., syntactic information) to learn and apply response classification labels for opinion text responses. In particular, the response analysis system employs part of speech information patterns without regard to word patterns to determine whether words in a text response correspond to an opinion, the target of the opinion, or neither. In addition, the trained response classification neural network has a significantly reduced learned parameter space, which decreases processing, memory requirements, and overall complexity.

  • Patent number: 8932290
    Abstract: A tissue ablation probe is provided. The tissue ablation probe comprises an elongated shaft, at least one electrode tine carried by the elongated shaft, at least one tine exit from which the electrode tine(s) can be deployed from the elongated shaft and retracted within the elongated shaft, and a sheath covering the electrode tine exit(s). The sheath may, e.g., line an exterior surface of the elongated shaft or an interior surface of the elongated shaft. The sheath has at least one tine valve (e.g., a slit) positioned over the electrode tine exit(s) and configured to open when the electrode tine is deployed and to close when the electrode tine(s) is retracted. In one embodiment, the tine valve(s) is configured to open in response to pressure exerted during deployment of the electrode tine(s). In another embodiment, the tine valve(s) is configured to hinder the entry of biological material within the elongated shaft.

  • Publication number: 20050289192
    Abstract: The invention is directed towards methods and systems for centrally administering navigational portions or mastheads of multiple web pages. In an embodiment, a computing device has a web page displayed on the computing device. A conversion utility is accessible via the Internet, and a file having navigation source code is provided. As the web page is loaded, the computing device sends a request for resultant code to the conversion utility. The conversion utility upon receiving the request retrieves the file having navigation source code and converts the navigation source code into resultant code. That resultant code is then transmitted back to the computing device and is loaded by the web page. Because the resultant code is generated when requested, the web page always receives the most recent version of the resultant code. In this sense, dynamic navigation is provided.

  • Patent number: 6935151
    Abstract: A hot forming die (10) has forming surfaces (16,18) and the forming surfaces have a nickel oxide layer (20). A stop off material coating (22) builds up on the nickel oxide layer (20) in operation. A method of cleaning the forming surfaces (16,18) of the hot forming die (10) includes washing the forming surfaces (16,18) of the hot forming die (10) in water to remove the stop off material (22) without removing the nickel oxide layer (20) from the forming surfaces (16,18). The forming surfaces (16,18) may be soaked in water (26) and/or a jet (30) of pressurized water may be directed onto the forming surfaces (16,18). The stop off material is quickly removed without damaging the forming surfaces (16,18). The retention of the nickel oxide layer (20) improves the quality of the hot-formed articles and the interval between cleaning of the hot forming die (10) is increased.

  • Publication number: 20050172694
    Abstract: A forming die (10) comprises a first die part (12) and a second die part (14). The first die part (12) has a first shaped forming surface (16) and the second die part (14) has a second shaped forming surface (18). The first die (12) has a number of pillars (28,30,32,34). Two of the pillars (28,34) are arranged at a first side of the first die (12) and two of the pillars (30,32) are arranged at a second opposite side of the first die (12). The second die (14) has a number of pillars (44,46,48,50). Two of the pillars (44,50) are arranged at the first side of the second die (14) and two of the pillars (46,48) are arranged at the second opposite side of the second die (14). The pillars (28,30,32,34) on the first die (12) are locatable on the pillars (44,46,48,50) on the second die (14). The pillars (28,30,32,34) on the first die (12) and the second die (44,46,48,50) have interlocking means (28B,30B,32B,34B, 44B,46B,48B,50B) to prevent relative movement between the first die (12) and the second die (14).
