Episodic Reasoning for Vision-Based Human Action Recognition

Algorithm 1

Perform estimation (actions).

(1) Actions = 𝑎₁,𝑎₂,𝑎₃,𝑎₄,…,𝑎_𝑁

(2)  for  𝑖=0 to 𝑁  do

(3)    if  𝑖==0  then

(4)   create(main_belief)

(5)   assert(“walk”, main_belief)

(6)   end if

(7)   constraints = WK(𝑎_𝑖)

(8)   if DSK(constraints) == true then

(9)   mark_expectations(active_belief)

(10)      mark_expectations(𝑎_𝑖)

(11)  if isExpectationUnique(expectation) then

(12)     assert(𝑎_𝑖, active_belief)

(13)       end if

(14)      activate(𝑏_𝑖 + 1)

(15)   else

(16)       discard(𝑎_𝑖)

(17)   end if

(18)  end for
