The training data may include, for example, and without limitation, the driving history of a user who directly drives a vehicle. The training data may include, for example, and without limitation, traffic information classified according to predetermined criteria. The predetermined criteria may, for example, relate to a specific time, a specific type, etc.

The pre-processor 810-2 may include various processing circuitry and/or program elements and preprocess the data obtained by the data acquisition unit 810-1.
The pre-processor 810-2 may provide the obtained data in a pre-defined format so that the model training unit 810-4 may use data for training a data recognition model. For example, the pre-processor 810-2 may provide voice data obtained by the data acquisition unit 810-1 as text data, and image data as image data in a predetermined format. The pre-processed data may be provided to the model training unit 810-4 as training data.

For example, the model training unit 810-4 may train a data recognition model through supervised learning using at least part of the training data as determination criteria. The model training unit 810-4, for example, may train itself using training data without additional supervising, and train a data recognition model through unsupervised learning, which finds criteria for determining the situations.
The model training unit 810-4 may train section criteria on which training data is to be used for determining a driving route to destination or a driving habit.
The data recognition model may be established considering, for example, and without limitation, the applicability of a recognition model, the purpose of training, or the computer function of an apparatus. The data recognition model, for example, may be a model based on neural network. The data recognition model may be designed to simulate the human brain structure in a computer. The data recognition model may include a plurality of network nodes having weight values to simulate neurons of the neural network of human being. The plurality of network nodes may establish connection relationships to simulate the synaptic activity to transmit and receive signals through synapses by neurons. For example, the data recognition model may include a neuron network model, a deep-learning model developed from the neuron network model. The plurality of network nodes in the deep-learning model may be disposed in different depths (or layers), and transmit and receive data according to a convolution connection relationship.
For example, a model such as Deep Neural Network (DNN), Recurrent Neural Network (RNN), or Bidirectional Recurrent Deep Neural Network (BDNR) may be used as a data recognition model, but the present disclosure is not limited thereto.
According to various embodiments of the present disclosure, the model training unit 810-4, if there are a plurality of data recognition models built in advance, may determine a data recognition model, in which the input training data and the basic training data are highly relevant, as the data recognition model to be trained. In this case, the basic training data may be pre-classified by data type, and the data recognition model may be pre-built in advance by data type. For example, the basic training data may be pre-classified on the basis of various criteria such as the region where the training data is generated, a time at which training data is generated, the size of the training data, the genre of the training data, the creator of the training data, the type of object in the training data, etc.
The model learning unit 810-4 may also train a data recognition model using a learning algorithm including, for example, an error back-propagation method or a gradient descent method.
The model training unit 810-4, for example, may train a data recognition model through supervised learning using a determination criterion as an input value. In addition, the model training unit 810-4, for example, may train itself using necessary training data without additional training, and train a data recognition model through non-supervised training, which finds a driving route to destination or a driving habit. The model training unit 810-4, for example, may train a data recognition model through reinforcement learning using a feedback on whether the result of the driving route to destination or the driving habit is appropriate according to training.
Based on the data recognition model being trained, the model training unit 810-4 may store the trained data recognition model. The model training unit 810-4 may store the trained data recognition model in the memory 150 of the autonomous driving apparatus 100.

In this case, the evaluation data may be pre-defined data for evaluating the data recognition model.
For example, the model evaluation unit 810-5, among the recognition result of the data recognition model trained with regard to the evaluation data, when the number or ratio of evaluation data of which recognition result is not accurate exceeds a predetermined threshold value, may evaluate that the predetermined criteria is not satisfied. For example, when the predetermined criteria is defined as a ratio of 2%, and when the trained data recognition model outputs an inappropriate recognition result with regard to the evaluation data exceeding 20 out of 1000 of the evaluation data, the model evaluation unit 810-5 may evaluate that the trained data recognition model is not appropriate.
When there are a plurality of trained data recognition models, the model evaluation unit 810-5 may evaluate that each trained data recognition model satisfies predetermined criteria, and determine the model satisfying the predetermined criteria as a final data recognition model. For example, when there are a plurality of models satisfying the predetermined criteria, the model evaluation unit 810-5 may determine any one or the predetermined number of models preset in descending order of evaluation score, as a final data recognition model.
