Apparatus and method of diagnosing a cause of increased exhaust gas using an autoencoder, and a vehicle including the same

A method for diagnosing a cause of an increase in exhaust gas using an autoencoder, the method comprising:

• receiving input data, wherein the input data includes at least two or more factors including a sensed value;
• determining a reconstruction error for each of the at least two or more factors, wherein the reconstruction error is a reconstruction error between the input data and restored data obtained by inputting the input data to a pre-learned autoencoder;
• and
• diagnosing the cause of the increase in exhaust gas, based on each of the reconstruction errors.

A vehicle including an apparatus for diagnosing a cause of an increase in exhaust gas using an autoencoder, wherein the apparatus comprises:

• at least one processor;
• and
• a storage medium configured to store a computer-readable instruction,
• wherein when the computer-readable instruction is executed by the at least one processor, the computer readable instruction is configured to cause the at least one processor to:
• receive input data, wherein the input data includes at least two or more factors including a sensed value;
• determine a reconstruction error for each of the at least two or more factors, wherein the reconstruction error is a reconstruction error between the input data and restored data obtained by inputting the input data to a pre-learned autoencoder;
• and
• diagnose the cause of the increase in exhaust gas, based on each of the reconstruction errors.
