280 results about "Function type" patented technology

In computer science, a function type (or arrow type or exponential) is the type of a variable or parameter to which a function has or can be assigned, or an argument or result type of a higher-order function taking or returning a function.

Computer implemented machine learning method and system including specifically defined introns

In a computer implemented learning and / or process control system, a computer model is constituted by the most currently fit entity in a population of computer program entities. The computer model defines fitness as a function of inputs and outputs. A computing unit accesses the model with a set of inputs, and determines a set of outputs for which the fitness is highest. This associates a sensory-motor (input-output) state with a fitness in a manner that might be termed "feeling".The learning and / or control system preferably utilizes a Compiling Genetic Programming System (CGPS) in which one or more machine code entities such as functions are created which represent solutions to a problem and are directly executable by a computer. The programs are created and altered by a program in a higher level language such as "C" which is not directly executable, but requires translation into executable machine code through compilation, interpretation, translation, etc. The entities are initially created as an integer array that can be altered by the program as data, and are executed by the program by recasting a pointer to the array as a function type. The entities are evaluated by executing them with training data as inputs, and calculating fitnesses based on a predetermined criterion. The entities are then altered based on their fitnesses using a genetic machine learning algorithm by recasting the pointer to the array as a data (e.g. integer) type. This process is iteratively repeated until an end criterion is reached.

The entities evolve in such a manner as to improve their fitness, and one entity is ultimately produced which represents an optimal solution to the problem. Each entity includes a plurality of directly executable machine code instructions, a header, a footer, and a return instruction. The instructions include branch instructions which enable subroutines, leaf functions, external function calls, recursion, and loops. The system can be implemented on an integrated circuit chip, with the entities stored in high speed memory in a central processing unit.

The alteration process is controlled such that only valid instructions are produced. The headers, footers and return instructions are protected from alteration. The system can be implemented on an integrated circuit chip, with the entities stored in high speed memory in a central processing unit.

Relevance vector machine-based multi-class data classifying method

InactiveCN102254193AAvoid Category OverlapAvoid approximationCharacter and pattern recognitionValue setData set
The invention provides a relevance vector machine-based multi-class data classifying method, which mainly solves the problem that the traditional multi-class data classifying method cannot integrally solve classifying face parameters and needs proximate calculation. The relevance vector machine-based multi-class data classifying method comprises a realizing process comprising the following steps of: partitioning a plurality of multi-class data sets and carrying out a normalizing pretreatment; determining a kernel function type and kernel parameters; setting basic parameters; calculating the classifying face parameters; calculating lower bounds of logarithms and solving variant values of the lower bounds of the logarithms and adding 1 to an iterative number; if the variant values of the lower bounds of the logarithms are converged or the iterative number reaches iterating times, finishing updating the classifying face parameters, and otherwise, continuing to updating; and obtaining a prediction probability matrix according to the updated classifying face parameters, wherein column numbers corresponding to a maximum value of each row of the matrix compose classifying classes for testing the data sets, and samples which have the prediction probability less than a false-alarm probability and the detection probability corresponding to a false-alarm probability value set in a curve are rejected. The relevance vector machine-based multi-class data classifying method has the advantages of obtaining classification which is comparable to that of an SVM (Support Vector Machine) by using less relevant vectors and rejecting performance and can be used for target recognition.

Fast traffic signboard recognition method based on convolution neural network

The invention aims to solve the problems in the existing traffic signboard recognition method that the recognition target falls into a single group and the speed in doing so is slow. The invention, out of this concept, provides a fast traffic signboard recognition method based on convolution neural network, referred to as FTSR-CNN in abbreviation. This method comprises: using the convolution kernel sliding filter extracted characteristics; obtaining the loss of the network in the forward learning process, and ensuring the accuracy of the network model to the recognition of multiple categories of signboards; optimizing the network performances through the adjustment of the parameters, the activation of the function types and the reduction of dimensions for better accuracy and timeliness eventually; and at the same time, in order to make the samples more diverse, conducting data adding and expanding to the samples in the data set based on affine transformation. The recognition rates of the FTSR-CNN for two data set tests of the German traffic signboard data set GTSRB and the Tsinghua-Tencent 100K are recorded as 95.74% and 96.67% respectively. The results indicate that the recognition speed is increased on the same recognition accuracy level through the modification of a previous model network and the start up of different training strategies by the FTSR-CNN.
