Predict the age of a person in years, given their first name.

Classes

  • This classifier is based on the US census data. It will give poor performances for names that are rare in the US.

Out[1]=1
In[2]:=2
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-basvfq
Out[2]=2

The most likely value of this distribution is the following:

In[3]:=3
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-za4le1
Out[3]=3

Load the PredictorFunction corresponding to the built-in predictor:

In[1]:=1
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-jsnagu
Out[1]=1

Obtain information about the predictor from Information:

In[2]:=2
✖

Out[2]=2

Options  (2)Common values & functionality for each option

IndeterminateThreshold  (1)

Use a custom IndeterminateThreshold after loading the PredictorFunction:

In[1]:=1
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-8szzhm
Out[1]=1
In[2]:=2
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-ejjm9x
Out[2]=2

Update the value of the threshold in the predictor:

In[3]:=3
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-0yofi2
Out[3]=3

UtilityFunction  (1)

Obtain the utility function of the predictor that corresponds to a DiracDelta function:

In[1]:=1
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-c2z9s6
Out[1]=1

This means by default, the value with the highest probability density is predicted:

In[2]:=2
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-v7f7d4
Out[2]=2

Change the utility function to predict the mean value instead of the most likely value:

In[3]:=3
✖
https://wolfram.com/xid/0e23062ebyvwb0d3bsu3-bf90a9
Out[3]=3
