The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
A neural network has been trained for multi-class classification using cross-entropy but has not necessarily achieved a global or local minimum on the training set.
The output of the neural network is $\mathbf{z}=[z_1,\ldots,z_d]^ op$ obtained from the penultimate values $\mathbf{x}=[x_1,\ldots,x_d]^ op$ via softmax $z_k= rac{\exp(x_k)}{\sum_{i}\exp(x_i)}$ that can be interpreted as a probability distribution over the $d$ possible classes.
The cross-entropy is given by $H(\mathbf{y},\mathbf{z})=-\sum_{i=1}^{d} y_i \ln{z_i}$ where $\mathbf{y}$ is one-hot encoded meaning the entity corresponding to the true class is 1 and other entities are 0.
We now modify the neural network, either by scaling $\mathbf{x} \mapsto lpha \mathbf{x}$ where $lpha \in \R_{>0}$ or through a shift $\mathbf{x} \mapsto \mathbf{x} + b\mathbf{1}$ where $b \in \R$.
The modified $\mathbf{x}$ values are fed into the softmax to obtain the final output and the network / parameters are otherwise unchanged.
How do these transformations affect the training accuracy of the network?
A. One transformation has no effect, the other one decreases the accuracy in some cases (but never increases it).
B. One transformation has no effect, the other sometimes increases and sometimes decreases the accuracy.
C. Neither transformation affects the accuracy.
D. Both transformations decrease the accuracy in some cases (but never increase it).
E. Both transformations sometimes increase and sometimes decrease the accuracy.

A. The purpose of introducing probabilities at the syntactic level is to enable the parser to choose among different parses of an ambiguous sentence.
B. The probabilities aims at capturing linguistic phenomena that are hard to express in operational terms but can be estimated from linguistic corpora.
C. Probabilizing does not depend on the way the syntactic parser is used (either as a recognizer or as an analyzer).

Consider a learning algorithm that has the property that it depends only very weakly on the input data. E.g., this could be SGD where we choose a very small step size and only run for very few iterations. To go to the extreme, you can imagine a learning algorithm that always outputs the same model irrespective of the training set. Presumably such a learning algorithm will not give us good results. Why is that?
A. (a) Such a learning algorithm typically has a much larger generalization error than training error.
B. (b) Such a learning algorithm typically has a large bias.
C. (c) Such a learning algorithm is prone to overfitting.
