The present invention provides an electric power steering apparatus for controlling a motor based on a current command value calculated from a steering assist command value calculated based on a steering torque generated in a steering shaft and from a current detection value of the motor which gives a steering mechanism a steering assist force. In order to realize ideal road information sensitivity and steering feeling in frequency region at the same time, the electric power steering apparatus comprises a torque filter for processing a torque signal, an SAT estimating function, and an SAT filter for signal-processing SAT information from the SAT estimating function, and the electric power steering apparatus also comprises a control system with two degree of freedom which is capable of independently designing frequency characteristics of steering feeling and road information sensitivity.

Described is a mechanism by which application programs (or plug-ins) and an auxiliary service adjust the output and / or data available for output on an auxiliary device based on changes detected in the current context of the auxiliary display. Context sensors detect and report changes in context, whereby some action is taken with respect to what information is displayed or can be displayed on the auxiliary display device. Examples of context data that can change include the physical location of the display, detected movement or motion data, presence of a particular user or others, power state, network connectivity status, privacy status and so forth. The auxiliary device can have context as to its position relative to the main display. Information sensitivity levels may be used to specify whether an application program's data can be displayed, based on the perceived sensitivity of the information and the user's current context.

There is described a method for determining a level of sensitivity of information in an electronic document. The method comprises scanning a computer location to select the electronic document, such as an unstructured document in which the sensitive nature of a given portion of the contents is not trivial. In the electronic document, contents and metadata of the electronic document are scanned, and each occurrence of sensitive data is identified by classifying each portion of the contents forming the electronic document as sensitive, or not sensitive, per se. For each occurrence of the sensitive data, there are determined a type of the sensitive data and a risk score associated to the type of the sensitive data, for example from a knowledge base. Using the risk score of each occurrence of the sensitive data, one can determine an exposure risk score of the electronic document.

The embodiment of this specification provides a method for protecting the safety of a neural network model, including: obtaining a neural network model, including multiple network layers obtained by training with training data; for any first network layer among them, fixing other network layer parameters In the case of , the above-mentioned training data is used to perform the first parameter adjustment on the first network layer to obtain the first fine-tuning model; determine the first index value corresponding to the preset performance index of the first fine-tuning model, and the index of the preset performance index The value depends on the corresponding model, the relative size between the test loss on the test data and the training loss on the above training data; similarly, using the training data and test data to perform the second parameter adjustment on the first network layer, we get The second fine-tuning model, and determine the second index value; based on the relative size of the first index value and the second index value, determine the information sensitivity corresponding to the first network layer, and if it is greater than a predetermined threshold, the first network layer for security processing.
