Question 3: Brown clustering: [14 points] Wo are given a determiniatio elana function C:C(dog)=1C(man)=2C (womain) =2C (walk) =3 Which of the following are possible definitions of e for a model with this class function? Provide an explanation for each. 1. e(dog1)=1,e(man2)=0.5,e(woman2)=0.5, e(walk|3 )=1 2. e(dog1)=1,e(man2)=1,e(woman3)=0.5,e( walk 3)=0.5 3. e(dog1)=1,e(man2)=0.5,e(woman2)=0.5,e(man3)=0.5,e(walk3)=0.5 4. e(dog1)=1,e(man2)=0.9,e( woman 2)=0.1,e( walk 3)=1.0
