At the very end, for classification problems, there is a softmax layer.
It finally has a Softmax layer but none of the new layer types that MPS got.
In neural networks,we achieve the same objective using the well-known softmax layer:.
But we haven't yet seen how a softmax layer lets us address the learning slowdown problem.
Remember that the cross-entropy involves a log, computed on the output of the softmax layer.
In other words, the output from the softmax layer can be thought of as a probability distribution.
The softmax layer then turns those scores into probabilities(all positive, all add up to 1.0).
For example, pre-trained network on ImageNet comes with a softmax layer with 1000 categories.
The final softmax layer then receives this feature vector as input and uses it to classify the sentence;
In neural networks,we achieve the same objective using the well-known softmax layer:.
Keep this softmax layer in mind, as many of the subsequent word embedding models will use it in some fashion.
The learning slowdown problem:We have now built up considerable familiarity with softmax layers of neurons.
The softmax layer is disregarded as the outputs of the fully connectedlayer become the inputs to another RNN.
Calculating the average of all patch and add another softmax layer to produce the probability of each class for the entire image.
Using this softmax layer, the model tries to maximize the probability of predicting the correct word at every timestep\( t\).
However, I want to briefly describe another approach to the problem,based on what are called softmax layers of neurons.
Softmax-based approaches are methods that keep the softmax layer intact, but modify its architecture to improve its efficiency.
It would also have a softmax layer at the end, but because BNNS doesn't come with a softmax function I left it out.
In addition, instead of training many different SVM's to classify each object class,there is a single softmax layer that outputs the class probabilities directly.
Along with the softmax layer, a linear regression layer is also used parallely to output bounding box coordinates for predicted classes.
If our task is a classification on 10 categories,the new softmax layer of the network will be of 10 categories instead of 1000 categories.
Inverting the softmax layer Suppose we have a neural network with a softmax output layer, and the activations$a^L_j$ are known.
Sampling-based approaches onthe other hand completely do away with the softmax layer and instead optimise some other loss function that approximates the softmax. .
The second(and last) layer is a 10-node softmax layer- this returns an array of 10 probability scores that sum to 1.
Later, in Chapter 6, we will sometimes use a softmax output layer, with log-likelihood cost.
We add a pooling layer, some fully-connected layers, and finally a softmax classification layer and bounding box regressor.
