The acronym TAPS has been widely used for several datasets and methodologies across scientific, engineering, and AI domains. This article systematically reviews notable TAPS datasets and frameworks, focusing on their design, data collection, technical components, and impact in their respective fields. Particular attention is given to speech enhancement (Throat and Acoustic Paired Speech), scientific simulation surrogates (Tensor-decomposition-based A Priori Surrogate), multi-task learning (Task Adaptive Parameter Sharing), deep learning parallelism strategy search, tool-augmented personalization in dialogue agents, and photoproduction experiments. Each TAPS instance is analyzed for its foundational characteristics, intended applications, and technical innovations.

1. Throat and Acoustic Paired Speech (TAPS) Dataset for Speech Enhancement

The TAPS dataset (Kim et al., 17 Feb 2025) consists of paired throat and acoustic microphone recordings from 60 native Korean speakers under controlled laboratory conditions, targeting deep learning–based speech enhancement tasks. Each participant contributed 100 sentence utterances, dividing the cohort into 40 for training, and 10 each for development and testing, balanced across gender. The dataset contains approximately 10.2 hours of training data with additional 2.5 and 2.6 hours for development and testing, respectively.

Data acquisition involved a MEMS accelerometer–based throat microphone positioned supraglottically and a reference acoustic microphone 30 cm from the speaker’s mouth. Head stabilization with a support minimized spatial variance. Audio signals were filtered and synchronously recorded using custom logic, followed by upsampling and noise reduction (Demucs-based) in post-processing. The dataset is organized as a Hugging Face DatasetDict with speaker metadata, utterance text, durations, and both audio tracks accessible as Hugging Face Audio features.

To remedy time misalignment from anatomical and sensor-position delays, TAPS implements a cross-correlation–based optimal alignment strategy:

$D = \operatorname{argmax}_k \sum_n S_T(n) S_A(n+k)$

where $S_T(n)$ and $S_A(n)$ are throat and acoustic microphone signals, and $k$ is the lag maximizing similarity. The averaged global mismatch correction yields superior PESQ, STOI, and CER results compared to speaker- or utterance-wise corrections.

Mapping-based deep learning enhancement models, such as Demucs (U-Net + BLSTM) and SE-Conformer (Conformer blocks for sequential modeling), were benchmarked against a masking-based transformer (TSTNN). Results showed clear superiority for direct mapping architectures in reconstructing high-frequency unvoiced phonemes and overall speech clarity. This dataset addresses a critical resource gap for robust TMSE modeling in high-noise environments, facilitating generative models that learn $P(a[n]\,|\,t[n])$ (acoustic given throat signal), with potential for generalization to diverse languages and settings.

2. Tensor-decomposition-based A Priori Surrogate (TAPS) for Ultra Large-Scale Simulation

TAPS (Guo et al., 18 Mar 2025), as an Editor's term, refers to a data-free surrogate modeling framework for solving ultra high-dimensional parametric problems governed by PDEs. The approach compresses the solution space using canonical tensor decomposition (CANDECOMP/PARAFAC), modeling a multidimensional solution as

$$u_{I_1 I_2 \ldots I_D} \approx \sum_{m=1}^{M} \prod_{d=1}^{D} u^{[d]}_{I_d m}$$

which reduces complexity from $\mathcal{O}(n^D)$ to $\mathcal{O}(M D n)$.

Spatial, parametric, and temporal interpolation leverages C-HiDeNN: an AI-enhanced, locally supported finite element–type function characterized by hyperparameters $(s, a, p)$ for patch size, dilation, and polynomial reproduction order:

$u^h(x) = \sum_{k} \tilde{N}_k(x; s, a, p) u_k$

guaranteeing arbitrary convergence rates and Kronecker delta property at nodes.

Weak formulation in the generalized Galerkin sense integrates governing equations over all independent variables. Matrix block structures enable separated subspace updates for spatial, parametric, and temporal unknowns, solved via subspace iteration.

Empirical results on large-scale additive manufacturing yielded approximately 1,370$\times$ speedup, 14.8$\times$ memory savings, and 955$\times$ reduction in storage compared to classical FD methods for $3.46 \times 10^9$ DoFs. The framework is applicable to design in additive manufacturing, IC layout, or any ultra high-dimensional physics-based simulation, with extensibility toward adaptive solvers and multiscale variants.

3. Task Adaptive Parameter Sharing (TAPS) Dataset for Multi-Task Learning

TAPS (Wallingford et al., 2022) in this context denotes a neural method and benchmark suite for efficient multi-task learning. The framework utilizes a sparse layer-wise parameter adaptation mechanism, optimizing layer selection and adaptation jointly:

$w_i' = w_i + I_\tau(s_i) \cdot \delta w_i$

where $w_i$ are frozen base weights, $\delta w_i$ task-specific residuals, and $I_\tau(s_i)$ a thresholded indicator for adaptation on layer $i$.

The core loss formulation comprises a task performance objective and sparsity penalty:

$$\min_{\delta w, s} L_D(w) + \frac{\lambda}{L} \sum_{i=1}^{L} |s_i|$$

promoting minimal parameter growth for new tasks. The approach is architecture-agnostic (ResNet, DenseNet, ViT) and can be implemented with a custom wrapper per layer. Evaluations on the ImageNet-to-Sketch suite, Visual Decathlon Challenge, and DomainNet demonstrate state-of-the-art accuracy/parameter efficiency trade-offs. TAPS is notably effective in both incremental and joint MTL regimes, minimizing interference and catastrophic forgetting.

4. TAPS: Topology-Aware Intra-Operator Parallelism Strategy Searching

TAPS (Liang et al., 2023), as documented in deep learning system literature, is an automatic parallelism strategy search algorithm designed for distributed training across multi-node clusters. The algorithm generates parallelism strategies by analyzing computation graphs and device graphs that carry operator and topology metadata, solving an Integer Linear Programming (ILP) problem on an auxiliary graph that encodes candidate strategies and associated communication operations.

Distinct from volume-based cost estimation, TAPS employs a topology-aware cost model:

$$B_e = \begin{cases} B_\text{intra} & \text{if } ct_T = 0 \ B_\text{inter}/ct_T & \text{if } ct_T > 0 \end{cases}$$

where $ct_T$ counts inter-node communication groups, and $B_\text{intra}$, $B_\text{inter}$ are intra/inter-node bandwidths. Communication cost per operation, e.g. AllReduce, scales as $C = V/B_e$.

In empirical benchmarks (AlexNet, Megatron-LM variants), TAPS achieves up to 85% reduction in communication cost relative to non-topology-aware methods. The auxiliary graph structure supports rapid strategy searching on large models, and the algorithm is amenable to integration with auto-parallelization infrastructures.

5. TAPS: Tool-Augmented Personalisation via Structured Tagging in Goal-Oriented Dialogue

TAPS (Taktasheva et al., 25 Jun 2025) targets personalized tool use within LLMs for goal-oriented dialogue agents. The system consists of a structured tagging tool that converts standing instructions into hierarchically tagged representations, e.g.:

〈a:GET_EVENTS〉 ... 〈sl:CITY〉 New York 〈/sl〉 ... 〈/a〉

where tags indicate API endpoints and argument slots. A supplementary uncertainty-based tool detector uses the Least Confidence metric to decide when structured tagging should be invoked versus direct model prediction:

$$\Delta = 1 - \max_t P(\text{token}_t \mid \text{context})$$

If $\Delta < \tau$, the output is accepted; otherwise, input is augmented and regenerated. This structured representation mitigates errors in slot filling and semantic mapping, significantly improving both exact match and slot-wise F1 on the NLSI benchmark (+16.5% EM, +16.9% slot-F1).

6. TAPS in Photon and Hadron Physics Experiments

Historically, TAPS designates specific detector components and experiment configurations in photon spectroscopy and hadron physics domains (CBELSA/TAPS, Crystal Ball/TAPS) (Hartmann, 2011, Sokhoyan, 2011, Aguar-Bartolomé et al., 2013, Hartmann, 2014, Nefkens et al., 2014). In these contexts:

• TAPS forms the forward electromagnetic calorimeter array complementing the Crystal Barrel detector.
• Datasets comprehensively cover observables $T$ (target asymmetry), $P$ (recoil polarization), $H$ (double polarization), $I^c$, $I^s$ (polarization modulations in double-meson photoproduction), and cross-section measurements for processes like $\gamma p \rightarrow K^0 \Sigma^+$, $\pi^0$, $\eta$ photoproduction.
• Novel measurements and precise binning (energy, angular, invariant mass spectra) enable improved constraints on baryon resonance models through robust partial-wave analyses.

These datasets exhibit high event statistics, fine angular resolution, and systematic background control, serving as benchmarks in experimental hadronic physics and nucleon resonance characterization.

7. Future Directions and Open Problems

Challenges and future development points across TAPS datasets include:

• Expansion to multi-lingual speech corpora and dynamic alignment strategies in TMSE.
• Integration of advanced solvers and adaptive mesh refinement in tensor-decomposition-based surrogates.
• Automated hyperparameter selection and hybrid modeling (physics-informed + data-driven) for simulation frameworks.
• Extension to overlapping communication/computation and more precise network bandwidth models in parallel training strategy search.
• Enhanced structured representation schemes for LLMs personalization and robust slot argument detection in evolving API ontologies.
• Ongoing precision measurements in hadronic experiments and extraction of higher-order polarization observables.

A plausible implication is that the unification of the TAPS acronym across diverse technical contexts illustrates convergence in the scientific community toward systematic, structured data and algorithmic frameworks for high-fidelity modeling, efficient learning, and robust measurement protocols.
