- # Setup
- Which of the following equations are incorrect according to the specification?
- # Notation
- A neural network is a function $F(x) = y$ that accepts an input $x \in \mathbb{R}^n$
- and produces an output $y \in \mathbb{R}^m$.
- The model $F$ also implicitly depends on some model parameters $\theta$; in our work
- the model is fixed, so for convenience we don't show the dependence on $\theta$.
- In this paper we focus on neural networks used as an $m$-class classifier.
- The output of the network is computed using the softmax function,
- which ensures that the output vector $y$ satisfies
- $0 \le y_i \le 1$ and $y_1 + \dots + y_m = 1$.
- The output vector $y$ is thus treated as a probability distribution, i.e.,
- $y_i$ is treated as the probability that input $x$ has class $i$.
- The classifier assigns the label $C(x) = \arg\max_i F(x)_i$ to the input $x$.
- Let $C^*(x)$ be the correct label of $x$.
- The inputs to the softmax function are called \emph{logits}.
- We use the notation from Papernot et al. \cite{distillation}: define $F$ to
- be the full neural network including the softmax function, $Z(x) = z$ to be the output of
- all layers except the softmax (so $z$ are the logits), and
- \begin{equation*}
- F(x) = \softmax(Z(x)) = y.
- \end{equation*}
- A neural network typically \footnote{Most simple networks have this simple
- linear structure, however other more sophisticated networks have
- more complicated structures (e.g., ResNet \cite{he2016deep} and Inception \cite{szegedy2015rethinking}).
- The network architecture does not impact our attacks.}
- consists of layers
- \begin{equation*}
- F = \softmax \circ F_n \circ F_{n-1} \circ \cdots \circ F_1
- \end{equation*}
- where
- \begin{equation*}
- F_i(x) = \sigma(\theta_i \cdot x) + \hat\theta_i
- \end{equation*}
- for some non-linear activation function $\sigma$, some matrix $\theta_i$ of model
- weights, and some vector $\hat\theta_i$ of model biases. Together $\theta$ and
- $\hat\theta$ make up the model parameters.
- Common choices of $\sigma$
- are tanh \cite{mishkin2015all}, sigmoid, ReLU \cite{maas2013rectifier}, or ELU \cite{clevert2015fast}.
- In this paper we focus primarily on networks that use a ReLU activation function,
- as it currently is the most widely used
- activation function
- \cite{szegedy2015rethinking,springenberg2014striving,mishkin2015all,distillation}.
- # Specification:
- We define an objective function $f$ such that
- $C(x+\delta) = t$ if and only if $f(x+\delta) \le 0$.
- There are many possible choices for $f$:
- # The equations
- \begin{align*}
- f_{1}(x') &= -\loss_{F,t}(x') + 1\\
- f_{2}(x') &= (\max_{i \ne t}( F(x')_i) - F(x')_t)^+\\
- f_{3}(x') &= \text{softplus}(\max_{i \ne t}(F(x')_i) - F(x')_t)-\log(2)\\
- f_{4}(x') &= (0.5 - F(x')_t)^+\\
- f_{5}(x') &= -\log(2 F(x')_t - 2)\\
- f_{6}(x') &= (\max_{i \ne t}( Z(x')_i) - Z(x')_t)^+\\
- f_{7}(x') &= \text{softplus}(\max_{i \ne t}(Z(x')_i) - Z(x')_t)-\log(2)
- \end{align*}
- where $s$ is the correct classification, $(e)^+$ is short-hand for
- $\max(e,0)$, $\text{softplus}(x) = \log(1+\exp(x))$, and
- $\loss_{F,s}(x)$ is the cross entropy loss for $x$.

- Consider each equation one by one. End your answer with a python list of numbers [1,2,3,4,5,6,7] for those that are wrong.
