The weights r z r_{z} , r i r_{\mathrm{i}} , r f r_{\mathrm{f}} , and r o r_{\mathrm{o}} correspond to the recurrent weights between hidden state h t − 1 h_{t-1} and cell input, input gate, forget gate, and output gate, respectively. b z b_{z} , b i b_{\mathrm{i}} , b f b_{\mathrm{f}} , and b o b_{\mathrm{o}} are the corresponding bias terms. φ \varphi and ψ \psi are the cell input and hidden state activation functions (typically tanh \tanh ). ψ \psi is used to normalize or squash the cell state, which would be unbounded otherwise. All gate activation functions are sigmoid, i.e., σ ⁡ ( x ) = 1 / ( 1 + exp ⁡ ( − x ) ) \sigma\left(x\right)=1/(1+\exp(-x)) . In later formulations, multiple scalar memory cells 𝒄 t ∈ ℝ d \bm{c}_{t}\in\mathbb{R}^{d} were combined in a vector, which allows the usage of recurrent weight matrices 𝑹 ∈ ℝ d × d \bm{R}\in\mathbb{R}^{d\times d} to mix the cell outputs of memory cells ( Greff et al., 2015 ) , for more details see Appendix A.1 . Ablation studies showed that all components of the memory cell are crucial ( Greff et al., 2015 ) .

### 2.2 sLSTM

To empower LSTMs with the ability to revise storage decisions, we introduce exponential gates (red) together with normalization and stabilization. In particular, input and forget gates can have exponential activation functions. For normalization, we introduce a normalizer state that sums up the product of the input gate times all future forget gates.

The scalar sLSTM forward pass is: = ​ + ​ \displaystyle=\ \mathchoice{\hbox to24.46pt{\vbox to8.44pt{\pgfpicture\makeatletter\hbox{\hskip 12.22807pt\lower-1.5pt\hbox
