Problems solved by technology

[0003] However, in the devices described in the above documents, when executing vehicle functions, the user interface needs to be switched from the operation mode of manually inputting the options displayed on the touch screen to the operation mode of using voice input, which inevitably causes a burden on the driver. Increase
[0004] In addition, in the device described in the above-mentioned documents, although the entrance of the voice operation is simplified, the subsequent operation only realizes the same function as that of the existing voice dialogue system. Therefore, it is expected to further reduce the burden on the driver.

other Embodiment approach

[0118] (Other Embodiments) In addition, each of the above-described embodiments can also be implemented as follows.

[0119]- In the above-mentioned first embodiment, the average entropy H(Ω) defining the degree of dispersion of the state space is calculated by adding the information entropy H(s) corresponding to all the states defining the state space. However, instead of this method, the average entropy H(Ω) can be calculated by adding the information entropy H(s) corresponding to a part of the states defining the state space.

[0120] - In the first embodiment described above, the random number δ is used as the threshold to be compared with the average entropy H(Ω). Thus, more diverse assignments can be made. However, in order to reduce the processing load, instead of this method, a fixed value may be used as the threshold value to be compared with the average entropy H(Ω). In this case, when the average entropy H(Ω) is less than a fixed value, the above-mentioned formula ...

Abstract

An information providing device includes an agent ECU (100) that sets a reward function through the use of history data on a response, from a driver, to an operation proposal for an in-vehicle component, and calculates a probability distribution of performance of each of actions constructing an action space in each of states constructing a state space, through reinforced learning based on the reward function. The agent ECU (100) calculates a dispersion degree of the probability distribution. The agent ECU (100) makes a trial-and-error operation proposal to select a target action from a plurality of candidates and output the target action when the dispersion degree of the probability distribution is equal to or larger than a threshold, and makes a definitive operation proposal to fix and output a target action when the value of the dispersion degree of the probability distribution is smaller than the threshold.

Description

technical field [0001] The present invention relates to an information providing device that stores and learns history data of a user's (driver's) response to provided information, and provides information that meets the user's (driver's) intention based on the learning result, and an information providing device that stores and learns. Storage media for information providers. Background technique [0002] As such an information providing device, for example, a device (user interface system) described in International Publication WO2015 / 162638 is known. In this device, when a function is executed by voice input, first, the information related to the current vehicle situation is used to estimate the candidate of the voice operation that the user (driver) may perform, and the probability of the candidate of the voice operation estimated above is The top 3 in order from high to low are displayed on the touch screen as options. Then, a candidate selected by the driver's manual...
