Embodiment 1
[0053] Embodiment 1 of the present invention provides a method for selecting cognitive attributes based on a sample set, such as figure 1 As shown, the specific methods include:
[0054] Step 1. Obtain the values of each attribute in the sample set.
[0055] Step 2. Calculate the probability of each attribute in the sample set taking its corresponding value, specifically:
[0056]
[0057] in, When the value of attribute U in the sample set is U j when the probability of The value of attribute U in the sample set is U j N is the total number of samples in the sample set.
[0058] Step 3. Calculate the additional information obtained when each attribute in the sample set takes its corresponding value. The additional information is determined according to the first information amount and the second information amount. The first information amount is the comprehensive information amount of the sample set, and the second The amount of information refers to the amount ...
Embodiment 2
[0071] Embodiment 2 of the present invention provides a method for determining the attribute of a cognitive target category based on a sample set. The method includes the above-mentioned method steps in Embodiment 1 of the present invention, and further includes the following steps, such as figure 2 Shown:
[0072] Using a method for selecting cognitive attributes based on a sample set in Embodiment 1 of the present invention to select cognitive attributes;
[0073] Obtain the value of the cognitive attribute of the cognitive target;
[0074] The value of the cognitive attribute of the cognitive target is used to screen the sample set to obtain a sample subset, and the category attribute of the cognitive target is determined by the category corresponding to the sample in the sample subset.
[0075] Specifically, in Embodiment 2 of the present invention, a sample set-based method for determining category attributes of cognitive targets includes the method steps in Embodiment ...
Embodiment 3
[0080] Embodiment 3 of the present invention shows a specific implementation method of the present invention in machine cognition technology in the field of artificial intelligence. Embodiment 3 of the present invention assumes that a certain machine cognition application scenario is: the category attribute of a certain cognition target needs to be determined. Assuming that the known sample set contains a total of five samples, each sample has category attributes, and the values of all attributes of each sample in the sample set are known by default, and the attribute values of each attribute of the cognitive target can be passed through the existing Technology is available.
[0081] Such as image 3 As shown, these five samples belong to three categories, and the corresponding category attributes are respectively recorded as category 1, category 2 and category 3. Each sample has attribute X and attribute Y, and the attribute X and attribute Y of each sample The value of ...
