Basic Examples  (2)

Use the "Spam" built-in classifier to detect if an email is spam from its content:

Wolfram Language code: Classify["Spam", "Dear recipient,*** Technologies announces the beginning of a new unprecendented global employment campaign.reviser yeller winers butchery twenties Due to company's exploding growth *** is expanding business to the European region.During last employment campaign over 1500 people worldwide took part in ***'s business and more than half of them are currently employed by the company.And now we are offering you one more opportunity to earn extra money working with *** Technologies.druggists blame classy gentry Aladdin We are looking for honest,responsible,hard-working people that can dedicate 2-4 hours of their time per day and earn extra Â$300-500 weekly.All offered positions are currently part-time and give you a chance to work mainly from home.lovelies hockey Malton meager reordered Please visit ***'s corporate web site (http://www.***.com/sta/home/0077.htm) for more details regarding these vacancies."]

Obtain the probabilities for the possible classes:

Wolfram Language code: Classify["Spam", "Dear recipient,*** Technologies announces the beginning of a new unprecendented global employment campaign.reviser yeller winers butchery twenties Due to company's exploding growth *** is expanding business to the European region.During last employment campaign over 1500 people worldwide took part in ***'s business and more than half of them are currently employed by the company.And now we are offering you one more opportunity to earn extra money working with *** Technologies.druggists blame classy gentry AladdinPlease visit ***'s corporate web site (http://www.***.com/sta/home/0077.htm) for more details regarding these vacancies.", "Probabilities"]

Obtain a ClassifierFunction for this classifier:

Wolfram Language code: c = Classify["Spam"]

Apply the classifier to a an email:

Wolfram Language code: c["Dear recipient, *** Technologies announces the beginning of a new unprecendented global employment campaign.reviser yeller winers butchery twenties Due to company's exploding growth *** is expanding business to the European region.During last employment campaign over 1500 people worldwide took part in ***'s business and more than half of them are currently employed by the company.And now we are offering you one more opportunity to earn extra money working with *** Technologies.druggists blame classy gentry AladdinPlease visit ***'s corporate web site (http://www.***.com/sta/home/0077.htm) for more details regarding these vacancies."]

Scope  (1)

Load the ClassifierFunction corresponding to the built-in classifier:

Obtain the possible classes using Information:

Wolfram Language code: Information[c, "Classes"]

Options  (2)

ClassPriors  (1)

Use a custom ClassPriors to restrict the possible outputs:

Wolfram Language code: Classify["Spam", "Dear recipient, *** Technologies announces the beginning of a new unprecendented global employment campaign.reviser yeller winers butchery twenties Due to company's exploding growth *** is expanding business to the European region.During last employment campaign over 1500 people worldwide took part in ***'s business and more than half of them are currently employed by the company.And now we are offering you one more opportunity to earn extra money working with *** Technologies.druggists blame classy gentry AladdinPlease visit ***'s corporate web site (http://www.***.com/sta/home/0077.htm) for more details regarding these vacancies.", ClassPriors -> <|False -> 0.4, True -> 0.6|>]

IndeterminateThreshold  (1)

Use a custom IndeterminateThreshold:

Wolfram Language code: Classify["Spam", "Dear recipient, *** Technologies announces the beginning of a new unprecendented global employment campaign.reviser yeller winers butchery twenties Due to company's exploding growth *** is expanding business to the European region.During last employment campaign over 1500 people worldwide took part in ***'s business and more than half of them are currently employed by the company", IndeterminateThreshold -> 0.7]
