Sensitivity Metrics

Given a text-audio pair $(t,a)$ we construct a counterfactual textual annotation $t^k$ by changing only the elements of category $k$ in sentence $t$ to be intuitively different (in the example above we consider $k=$ situational and therefore modify only the situation in which a song is engaged with). We present a set of metrics $\{s_k:k\in \mathrm{caption}\mathrm{sets}\}$ used to assess the output of a text-conditioned music generation model, such that

$$s_k=\frac{1}{n}[\sum _{i=1}^{n}1-cosine\mathrm{\_}sim(a_i,{\tilde{a}}_i^k)]$$

where $n$ is the number of data points and $a=M(t)$, $a^k=M(t^k)$ are the generated audio associated with an original textual annotation t and its counterfactual annotation $t^k$ constructed by exchanging subset $k$ for it’s counterfactual counterpart, respectively. Each metric is bounded between $(0,1)$ with higher values showing higher sensitivity.
