determine a context of the occupant;

infer, by the comfort model, a current continuous comfort index indicating a current comfort level of the occupant, based on the current ambient conditions, the current body parameters, and the context;

determine one or more of the current ambient conditions to be adjusted to improve the current comfort level of the occupant, by:

clustering, according to prior body parameters, the training samples that have a prior continuous comfort index better than the current continuous comfort index;

identifying a cluster having prior body parameters closest to the current body parameters;

calculating representative ambient conditions based on the prior ambient conditions of the identified cluster; and

identifying, as the determined one or more of the current ambient conditions, one or more of the current ambient conditions that are worse, by a predetermined benchmark, than the representative ambient conditions; and

adjust environmental conditions of a passenger compartment of the vehicle based on the determined one or more of the current ambient conditions.

clustering, according to prior body parameters, the training samples that have a prior continuous comfort index better than the current continuous comfort index;

identifying a cluster having prior body parameters closest to the current body parameters;

calculating representative ambient conditions based on the prior ambient conditions of the identified cluster; and

identifying, as the determined one or more of the current ambient conditions, one or more of the current ambient conditions that are worse, by a predetermined benchmark, than the representative ambient conditions; and

adjust one or more of the comfort facilities of the vehicle corresponding to the determined one or more of the current ambient conditions.

9. The system of claim 8 , wherein the machine learning approach is a regression analysis.

10. The system of claim 8 , wherein the current and prior ambient conditions include at least:

air temperature inside the vehicle;

14. The system of claim 8 , wherein the computer-executable instructions further cause the processor to infer a context of the occupant, including at least a recent activity of the occupant, and wherein the current continuous comfort index is based in part on the context.

15. An apparatus comprising:

a processor that executes computer-executable instructions stored on a computer-readable memory, wherein the computer-executable instructions cause the processor to:

train a comfort model corresponding to an occupant of a vehicle, by applying a machine learning approach to training samples, wherein a training sample includes:

past interior conditions associated with the vehicle and past biometric data associated with the occupant; and

a past continuous comfort index corresponding to the past interior conditions and the past biometric data, based on manual adjustments by the occupant to comfort facilities of the vehicle in response to the past interior conditions and the past biometric data;
