Wherein, okFor the output of neuron k, tkTarget for neuron k exports, and outputs is all nerves of output layer Unit's set.In conjunction with the embodiment of the present invention, described error function (3) can be converted into following formula:
E d = 1 2 ( S r - S p ) 2 - - - ( 4 )
In order to reduce error, right value update function may be defined as:
Δw j i = - η ∂ E d ∂ w j i - - - ( 5 )
Wherein wjiWeights for the input i of neuron j.
Solution procedure is:
∂ E d ∂ w j i = ∂ E d ∂ net j · ∂ net j ∂ w j i = ∂ E d ∂ net j x j i - - - ( 6 )
5.1, for output layer, as shown in Figure 5:
∂ E d ∂ net j = ∂ E d ∂ o j · ∂ o j ∂ net j - - - ( 7 )
Wherein:
∂ E d ∂ o j = ∂ ∂ o j 1 2 ( t j - o j ) 2 = 1 2 2 ( t j - o j ) ∂ ( t j - o j ) ∂ o j = - ( t j - o j ) - - - ( 8 )
∂ o j ∂ net j = ∂ σ ( net j ) ∂ net j = o j ( 1 - o j ) - - - ( 9 )
Abbreviation obtains:
∂ E d ∂ net j = - ( t j - o j ) o j ( 1 - o j ) - - - ( 10 )
Therefore, Δ wjiIt is represented by following formula:
Δw j i = - η ∂ E d ∂ w j i = η ( t j - o j ) o j ( 1 - o j ) x i j - - - ( 11 )
5.2, for hidden layer, as shown in Figure 6:
∂ E d ∂ net j = Σ k ∈ D o w n s t r e a m ( j ) ∂ E d ∂ net k ∂ net k ∂ net j = Σ k ∈ D o w n s t r e a m ( j ) - δ k ∂ net k ∂ o j ∂ o j ∂ net j = Σ k ∈ D o w n s t r e a m ( j ) - δ k w k j ∂ o j ∂ net j = Σ k ∈ D o w n s t r e a m ( j ) - δ k w k j o j ( 1 - o j ) - - - ( 12 )
Wherein:
δ k = - ∂ E d ∂ net k - - - ( 13 )
δ j = o j ( 1 - o j ) Σ k ∈ D o w n s t r e a m ( j ) δ k w k j - - - ( 14 )
Therefore:
Δwji=η δjxji (15)
Therefore for the neuron k of output layer:
δk←ok(1-ok)(tk-ok) (16)
Neuron h for hidden layer:
δ h ← o h ( 1 - o h ) Σ k ∈ o u t p u t s w k h δ k - - - ( 17 )
When calculating every layer of weights, respectively the δ of respective layer is substituted into following formula.
wji←wji+Δwji=wji+ηδjxji (18)
Wherein, xjiInput i for neuron j；
netj=∑ wjixjiWeighted sum for all inputs of neuron j；
ojOutput for neuron j；
tjTarget for neuron j exports；
σ is sigmod function；
Outputs is all neuronal ensembles of output layer；
DownStream (j) is all exporting neuron j as the neuronal ensemble inputted；
