# SOT-GLP: Multifaceted Research Applications

Searching arXiv for the primary SOT-GLP usage and related entries.
SOT-GLP is a non-unique label used in the research literature for several unrelated topics. Its most explicit and technically developed usage is the vision-language method "Local-Global Prompt Learning via Sparse Optimal Transport," a few-shot adaptation method for CLIP-like vision-language models. The same label also appears in the phrase "State-of-the-art, safety-oriented synthesis for GLP-1 RAs" in pharmacovigilance work on adverse side effects of glucagon-like peptide 1 receptor agonists, and it is additionally used in some summaries as a mapping label for research on Japaridze’s provability logic GLP rather than as an author-defined formal term [2603.08347, 2404.01358, 2504.01388].

## 1. Nomenclature and domain structure

The literature associates the string "SOT-GLP" with at least three distinct research families. In the vision-language setting, it is the exact name of a prompt-learning method: "Local-Global Prompt Learning via Sparse Optimal Transport" [2603.08347]. In drug safety analytics, it appears as "State-of-the-art, safety-oriented synthesis for GLP-1 RAs (SOT-GLP)" [2404.01358]. In provability-logic summaries, it functions as a shorthand header for state-of-the-art discussions of GLP, although several of those papers explicitly do not use the acronym "SOT-GLP" in the original article text [2404.04893, 2504.01388].

| Usage | Domain | Core referent |
|---|---|---|
| SOT-GLP | Vision-language learning | "Local-Global Prompt Learning via Sparse Optimal Transport" |
| SOT-GLP | Pharmacovigilance | "State-of-the-art, safety-oriented synthesis for GLP-1 RAs" |
| SOT-GLP | Modal logic summaries | Mapping label for GLP research, not a standard paper-defined name |

This multiplicity matters because the dominant modern usage is the vision-language method, whereas the pharmacovigilance and logic usages are semantically unrelated. A plausible implication is that retrieval systems and acronym-based searches can conflate distinct literatures unless the expansion is specified.

## 2. Local-Global Prompt Learning via Sparse Optimal Transport

In vision-language modeling, SOT-GLP is a few-shot adaptation method for vision-language models such as CLIP that augments global image-text alignment with fine-grained, local patch-prompt alignment [2603.08347]. The method is motivated by two stated limitations of existing prompt-learning approaches: global-only alignment tends to average over spatial regions and miss discriminative local cues, while prior local methods often select patches independently per prompt, causing redundant local feature usage and prompt overlap or collapse.

The architecture is a dual-branch design with shared global prompts and class-specific local prompts. The global branch matches the CLIP \([CLS]\) embedding to text embeddings produced by a small set of class-agnostic learned global prompts. The local branch performs fine-grained alignment between a sparse set of salient patches and multiple class-specific local prompts. Let \(C\) be the class set. The method learns global prompts \(P^g=\{p^g_m\}_{m=1}^{N_g}\) and class-specific local prompts \(P^\ell_c=\{p^\ell_{c,j}\}_{j=1}^{N_\ell}\). With tokenized class name \(\tau(c)\) and CLIP text encoder \(f_T\), the text embeddings are
\[
T^g_{c,m}=f_T([[SOS]; p^g_m; \tau(c); [EOT]]), \qquad
T^\ell_{c,j}=f_T([[SOS]; p^\ell_{c,j}; \tau(c); [EOT]]).
\]

For locality-aware patch features, SOT-GLP uses a dual-stream CLIP ViT-B/16 encoder. The original CLIP stream with Q-K attention yields the global image embedding \(Z_{\text{global}}\). A V-V stream enhances patch-level interactions by correlating value representations:
\[
A^{vv}_l=\text{softmax}(V_lV_l^\top/\sqrt{d}), \qquad
Y^{vv}_l=A^{vv}_lV_l, \qquad
Z^{vv}_l=Z^{vv}_{l-1}+\text{Proj}^v_l(Y^{vv}_l).
\]
The last-layer non-\([CLS]\) tokens optionally pass through a learnable linear projection \(W_{\text{local-proj}}\), yielding
\[
Z_{\text{local}}=(Z^{vv}_L)_{1:T}W_{\text{local-proj}}.
\]

To avoid dense alignment over all patches, the method computes a class-conditioned saliency score
\[
\sigma^{(i)}_{p,c}=\frac{1}{N_\ell}\sum_{j=1}^{N_\ell}(z^\ell_{i,p})^\top T^\ell_{c,j},
\]
then retains a shared top-\(K\) support
\[
S^{(i)}_c=\{z^\ell_{i,p}: \text{rank}(\sigma^{(i)}_{p,c})\le K\}.
\]
This shared support is used by all local prompts of class \(c\), so the prompts compete for the same pool of salient patches instead of independently re-selecting overlapping regions.

The alignment itself is formulated as balanced entropic optimal transport. For patch \(s_u\in S^{(i)}_c\) and prompt \(t_v\in L_c\), the similarity is \(\text{sim}_{uv}=s_u^\top t_v\), and a simple OT cost is \(C_{uv}=1-\text{sim}_{uv}\). The transport problem is
\[
\min_{T\ge 0} \langle C,T\rangle+\epsilon\sum_{u,v}T_{uv}(\log T_{uv}-1)
\]
subject to
\[
T\mathbf{1}=r,\qquad T^\top\mathbf{1}=c,
\]
with uniform marginals as a natural choice. Using Sinkhorn updates,
\[
K=\exp(-C/\epsilon), \qquad T=\text{diag}(u)K\text{diag}(v),
\]
the local score becomes
\[
\phi^{(i)}_c=\sum_{u=1}^K\sum_{v=1}^{N_\ell}T_{uv}\text{sim}_{uv}, \qquad
s^{\text{local}}_{i,c}=\phi^{(i)}_c/\tau.
\]
Global logits are averaged across \(N_g\) shared prompts, and the final class logit is
\[
s^{\text{final}}_{i,c}=s^{\text{global}}_{i,c}+\lambda s^{\text{local}}_{i,c}.
\]
Training uses cross-entropy with frozen CLIP vision and text encoders; only prompts and, optionally, the local projection are learned.

## 3. Empirical profile, ablations, and the accuracy-robustness trade-off

On the standard 11-dataset benchmark with 16-shot ViT-B/16, SOT-GLP achieves 85.1% average accuracy and outperforms prior prompt-learning methods, including GalLoP at 84.4% [2603.08347]. It reports state-of-the-art results on 9/11 datasets, including ImageNet 75.5%, Caltech101 97.4%, OxfordPets 94.8%, Cars 89.2%, Flowers102 99.2%, Food101 87.8%, SUN397 78.2%, DTD 77.1%, and UCF101 87.5%. For OOD detection, full SOT-GLP yields 28.1 FPR95 and 93.2 AUC average across ImageNet-OOD suites, while the projection-free variant improves to 23.8 FPR95 and 94.2 AUC.

The paper identifies a distinct accuracy-robustness trade-off in prompt learning. Learnable projections marginally boost in-distribution accuracy but alter the foundational feature space; the reported ablations attribute a \(+0.9\) percentage-point average accuracy gain to the local projection, while removing \(W_{\text{local-proj}}\) drops average accuracy from 85.1% to 84.2%. At the same time, the projection-free variant preserves the native geometry of the CLIP manifold and delivers the strongest OOD performance.

Ablations further isolate the role of each component. Removing V-V attention reduces average accuracy from 85.1% to 84.8%, with stronger gains on texture and scene datasets such as SUN397 \(+0.6\) and EuroSAT \(+1.9\) when V-V is present. Sharing local prompts across classes reduces average accuracy to 84.5% and hurts fine-grained datasets such as Aircraft \(-1.9\) and Cars \(-1.2\), indicating that class-specific specialization is important. The sparsity parameter peaks at \(K=10\); performance is stable for \(K\in[5,20]\) and drops at \(K=1\) or \(K=100\). The reported default hyperparameters are \(N_g=4\), \(N_\ell=4\), \(K=10\), and \(\lambda=0.25\), with SGD, learning rate 0.05, momentum 0.9, weight decay 0.01, cosine annealing, 50 epochs with 5-epoch warmup, mixed precision, effective batch size 32, and 4× RTX 3090. The V-V dual stream adds about 24% inference FLOPs relative to standard CLIP, from 44.9 to 58.8 GFLOPs [2603.08347].

## 4. SOT-GLP in GLP-1 receptor agonist pharmacovigilance

In digital health analytics, SOT-GLP denotes "State-of-the-art, safety-oriented synthesis for GLP-1 RAs" and refers to a pipeline for post-approval detection of adverse side effects of GLP-1 receptor agonists [2404.01358]. The study targets the problem that clinical trials often miss rare or latent adverse side effects, while traditional pharmacovigilance sources under-report events. The pipeline mines Reddit, X/Twitter, PubMed, manufacturer documents, and ChatGPT, then uses a pre-trained biomedical NER model, ScispaCy `en_ner_bc5cdr_md`, to extract and normalize adverse side effects.

The data sources are large. X/Twitter contributes 11,185 posts sampled as the 1,000 most recent posts for each of 12 GLP-1 RA names from 2017–2023. Reddit contributes 489,529 posts and comments from 14 health-related subreddits collected in 2022–2023. PubMed contributes 13,491 articles indexed 2017–2024 containing at least one drug name in title or abstract. SIDER v4.1 provides 5,868 adverse side effects across 1,430 drugs as the canonical adverse-event lexicon. Manufacturer labels and ChatGPT lists are used to define "established ASEs."

The workflow is: run NER on Datasets 1–3, match extracted entities to the SIDER ASE lexicon after normalization and stemming, integrate with manufacturer and ChatGPT lists, consolidate synonyms to standard ASE names, count mentions, analyze 14-day temporal bins, and build an ASE-ASE co-mention graph \(G=(V,E,W)\). Louvain clustering reveals four ASE clusters reflecting gastrointestinal distress, emotional or mental strain, somatic discomfort, and neurological disorders. The study reports 134 ASEs overall and identifies 21 potential ASEs absent from manufacturer reports at FDA approval and not listed by ChatGPT. These "social-only" signals are irritability, burns, numbness, hypogonadism, cough, paralysis, anger, hoarseness, bulimia, suicidal, anhedonia, frustration, onycholysis, endometriosis, ketonemia, apathy, aura, hirsutism, infertility, narcolepsy, and snoring.

Validation is exploratory rather than causal. The paper does not report Precision, Recall, or F1 for NER, and it does not perform direct external validation against FAERS or EudraVigilance. Instead, it introduces an Overlap metric,
\[
\text{Overlap}(f\%)=\frac{|P_{f\%}\cap I_d|}{|I_d|},
\]
where \(P_{f\%}\) is the set of ASEs from social media in the top \(f\%\) by mention frequency and \(I_d\) is the set of established ASEs. At 100%, Overlap is 0.53, meaning 53% of established ASEs were recovered from social media. The paper states explicitly that the 21 social-only ASEs are potential post-approval signals for pharmacovigilance rather than clinically validated causal findings [2404.01358].

## 5. GLP-related uses: unification, derivations, topology, and algebra

A separate body of literature connects the query string "SOT-GLP" to work on Japaridze’s polymodal provability logic GLP, although several of those papers do not use "SOT-GLP" as a formal title. GLP extends propositional logic with unary modal operators \([n]\) for each natural number \(n\in\omega\), with dual modalities \(\langle n\rangle A:=\neg[n]\neg A\), and includes Gödel-Löb logic for each modality together with interaction axioms across indices [2404.04893].

Within this literature, several major results are highlighted. "On the unification problem for GLP" proves that GLP has nullary unification type, more specifically that the formula \([1]p\) does not have maximal unifiers and has an infinite complete set of unifiers [2404.04893]. "(Non-)well-founded derivations in the provability logic \(\mathsf{GLP}\)" proves that cyclic derivations are conservative, that non-well-founded and well-founded derivations define the same proper infinitary extension, and that this extension is strongly algebraic and neighborhood complete with respect to local, global, and global-local consequence relations [2504.01388]. "Topological completeness of the provability logic GLP" shows that GLP is complete with respect to the class of all GLP-spaces, where modalities are interpreted as derivative operators of a polytopological space [1106.5693]. "Nested Sequents for Provability Logic GLP" presents a nested sequent proof system for GLP, proves cut elimination, and obtains the reduction of GLP to the fragment \(J\) syntactically [1410.6652]. "On Elementary Theories of GLP-Algebras" proves that the elementary theories of the free \(\emptyset\)-generated \(GLP_n\)-algebras are decidable for all finite ordinals \(n\) [1412.4439].

These results are logically coherent but terminologically heterogeneous. A plausible implication is that "SOT-GLP" in this domain is best read as an external aggregation label for state-of-the-art GLP topics rather than as a stable technical name internal to provability logic.

## 6. Adjacent SoT-based mappings that are not formal SOT-GLP names

Two additional papers are sometimes connected to the query through the acronym "SoT," but neither defines a formal object named "SOT-GLP." "SoT: Delving Deeper into Classification Head for Transformer" studies a second-order transformer classification head that combines the classification token with pooled word-token statistics using multi-headed global cross-covariance pooling with singular value power normalization [2104.10935]. In the associated mapping, "SOT-GLP" is interpreted as SoT with MGCrP as the global pooling module. The paper reports, for example, that on ImageNet with DeiT-T, ClassT achieves 72.2% top-1, WordT 77.9%, and ClassT+WordT 78.6%, and that with a strong 7-layer baseline on ImageNet, sum+GAP yields 73.85, sum+GCP 75.23, and sum+MGCrP 75.97 [2104.10935].

"SoT: Structured-of-Thought Prompting Guides Multilingual Reasoning in Large Language Models" introduces a training-free method for multilingual reasoning through Language Thinking Transformation and Structured Knowledge Transformation [2510.02648]. The summary explicitly notes that the acronym "GLP" does not appear in the paper text. The SoT pipeline formalizes reasoning steps \(\mathcal{R}\), structured knowledge \(\mathcal{K}\), language-specific knowledge \(\mathcal{K}^{L_s}\), and answer generation \(\mathcal{F}\), and reports benchmark gains on MGSM, MSVAMP, and XCOPA. For example, on XCOPA with gpt-3.5-turbo, SoT reaches 75.4% average accuracy versus EMCEI at 71.2%; on MGSM with Qwen2.5-7B, SoT reaches 68.3% versus EMCEI at 66.3% [2510.02648].

Taken together, these adjacent mappings show that "SOT-GLP" is not a controlled vocabulary term across arXiv-style research discourse. In practice, the exact expansion is decisive: in machine learning it most concretely denotes sparse-optimal-transport prompt learning for CLIP, in pharmacovigilance it denotes a multi-source adverse-event mining pipeline for GLP-1 receptor agonists, and in logic it often functions as a retrieval label for state-of-the-art work on GLP rather than as a canonical name [2603.08347, 2404.01358, 2404.04893].
