Sincretismos e Territorialidades da Umbanda: práticas de (re) existência no espaço concebido brasileiro

André Victor Mendes Rosa

O presente artigo analisa a religião de matriz africana Umbanda a partir de suas relações sociais e espaciais no Brasil. O objetivo é discutir as práticas de re-existência, ou seja, estratégias de resistência e adaptação, que a Umbanda desenvolve por meio de seu sincretismo religioso e de suas territorialidades. Essas territorialidades incluem espaços como encruzilhadas, praias, rios, pedreiras e estradas, além dos próprios terreiros, utilizados para oferendas e cultos. O artigo debate se o sincretismo representa um embranquecimento da cultura africana ou uma forma de adaptação e sobrevivência diante do racismo estrutural e da repressão histórica. A análise se baseia no conceito de espaço concebido de Henri Lefebvre, compreendendo a Umbanda como uma manifestação que resiste à ordem instituída e ao capitalismo brasileiro.

Exploration Space Theory: Formal Foundations for Prerequisite-Aware Location-Based Recommendation

Madjid Sadallah

Location-based recommender systems have achieved considerable sophistication, yet none provides a formal, lattice-theoretic representation of prerequisite dependencies among points of interest -- the semantic reality that meaningfully experiencing certain locations presupposes contextual knowledge gained from others -- nor the structural guarantees that such a representation entails. We introduce Exploration Space Theory (EST), a formal framework that transposes Knowledge Space Theory into location-based recommendation. We prove that the valid user exploration states -- the order ideals of a surmise partial order on points of interest -- form a finite distributive lattice and a well-graded learning space; Birkhoff's representation theorem, combined with the structural isomorphism between lattices of order ideals and concept lattices, connects the exploration space canonically to Formal Concept Analysis. These structural results yield four direct consequences: linear-time fringe computation, a validity certificate guaranteeing that every fringe-guided recommendation is a structurally sound next step, sub-path optimality for dynamic-programming path generation, and provably existing structural explanations for every recommendation. Building on these foundations, we specify the Exploration Space Recommender System (ESRS) -- a memoized dynamic program over the exploration lattice, a Bayesian state estimator with beam approximation and EM parameter learning, an online feedback loop enforcing the downward-closure invariant, an incremental surmise-relation inference pipeline, and three cold-start strategies, the structural one being the only approach in the literature to provide a formal validity guarantee conditional on the correctness of the inferred surmise relation. All results are established through proof and illustrated on a fully traced five-POI numerical example.

Subjectivity in the illness process and dialogue as a facilitator of new subjective senses

Manoel Vitor Noleto, Valéria Deusdará Mori

Abstract Objective The article aimed to study the subjective configurations of a person diagnosed with cancer based on the theoretical framework of the Theory of Subjectivity in a Historical-Cultural perspective as proposed by González Rey. Method For this purpose, the constructive-interpretative method was used, guided by the principles of Qualitative Epistemology, which consider the development of knowledge as constructive-interpretative production in its singular and dialogical scope. In the development of the investigation, individual conversational dynamics were used. Results The results presented describe and explore how the creation of a dialogical space as a facilitating tool for new subjective productions is essential for promoting ways to minimize psychic suffering. The favorable context allows for the expression of experiences and emotions that significantly contribute to the reduction of psychic suffering. Conclusion In this perspective, it was important to understand the human experience in a complex and singular way.

Conversational Lexicography: Querying Lexicographic Data on Knowledge Graphs with SPARQL through Natural Language

Kilian Sennrich, Sina Ahmadi

Knowledge graphs offer an excellent solution for representing the lexical-semantic structures of lexicographic data. However, working with the SPARQL query language represents a considerable hurdle for many non-expert users who could benefit from the advantages of this technology. This paper addresses the challenge of creating natural language interfaces for lexicographic data retrieval on knowledge graphs such as Wikidata. We develop a multidimensional taxonomy capturing the complexity of Wikidata's lexicographic data ontology module through four dimensions and create a template-based dataset with over 1.2 million mappings from natural language utterances to SPARQL queries. Our experiments with GPT-2 (124M), Phi-1.5 (1.3B), and GPT-3.5-Turbo reveal significant differences in model capabilities. While all models perform well on familiar patterns, only GPT-3.5-Turbo demonstrates meaningful generalization capabilities, suggesting that model size and diverse pre-training are crucial for adaptability in this domain. However, significant challenges remain in achieving robust generalization, handling diverse linguistic data, and developing scalable solutions that can accommodate the full complexity of lexicographic knowledge representation.

Knowledge Distillation from Large Language Models for Household Energy Modeling

Mohannad Takrouri, Nicolás M. Cuadrado, Martin Takáč

Machine learning (ML) is increasingly vital for smart-grid research, yet restricted access to realistic, diverse data - often due to privacy concerns - slows progress and fuels doubts within the energy sector about adopting ML-based strategies. We propose integrating Large Language Models (LLMs) in energy modeling to generate realistic, culturally sensitive, and behavior-specific data for household energy usage across diverse geographies. In this study, we employ and compare five different LLMs to systematically produce family structures, weather patterns, and daily consumption profiles for households in six distinct countries. A four-stage methodology synthesizes contextual daily data, including culturally nuanced activities, realistic weather ranges, HVAC operations, and distinct `energy signatures' that capture unique consumption footprints. Additionally, we explore an alternative strategy where external weather datasets can be directly integrated, bypassing intermediate weather modeling stages while ensuring physically consistent data inputs. The resulting dataset provides insights into how cultural, climatic, and behavioral factors converge to shape carbon emissions, offering a cost-effective avenue for scenario-based energy optimization. This approach underscores how prompt engineering, combined with knowledge distillation, can advance sustainable energy research and climate mitigation efforts.

Synergistic Knowledge

Christian Cachin, David Lehnherr, Thomas Studer

In formal epistemology, group knowledge is often modelled as the knowledge that the group would have, if the agents shared all their individual knowledge. However, this interpretation does not account for relations between agents. In this work, we propose the notion of synergistic knowledge which makes it possible to model those relationships.

Curiosity and Democracy: A Neglected Connection

Marianna Papastephanou

Curiosity’s connection with democracy remains neglected and unexplored. Various disciplines have mostly treated curiosity as an epistemic trait of the individual. Beyond epistemology, curiosity is studied as a moral virtue or vice of the self. Beyond epistemic and moral frameworks, curiosity is examined politically and decolonially. However, all frameworks remain focused on the individual and rarely imply a relevance of curiosity to democracy. The present article departs from such explorative frameworks philosophically to expand the research scope on curiosity in the direction of democratic theory. It highlights the complex politics of curiosity as a collective, rather than merely individual, desire for knowledge. I argue that curiosity should become a key analytical category for studying democracy as a political attitude and as a way of life. Investigations of the multifaceted curiosity of the demos may enhance the visibility of ethico-political issues that often escape the curious eye of citizens and researchers.

Mathematical Foundations for Joining Only Knowing and Common Knowledge (Extended Version)

Marcos Cramer, Samuele Pollaci, Bart Bogaerts

Common knowledge and only knowing capture two intuitive and natural notions that have proven to be useful in a variety of settings, for example to reason about coordination or agreement between agents, or to analyse the knowledge of knowledge-based agents. While these two epistemic operators have been extensively studied in isolation, the approaches made to encode their complex interplay failed to capture some essential properties of only knowing. We propose a novel solution by defining a notion of $μ$-biworld for countable ordinals $μ$, which approximates not only the worlds that an agent deems possible, but also those deemed impossible. This approach allows us to define a multi-agent epistemic logic with common knowledge and only knowing operators, and a three-valued model semantics for it. Moreover, we show that we only really need biworlds of depth at most $ω^2+1$. Based on this observation, we define a Kripke semantics on a canonical Kripke structure and show that this semantics coincides with the model semantics. Finally, we discuss issues arising when combining negative introspection or truthfulness with only knowing and show how positive introspection can be integrated into our logic.

AutoAlign: Fully Automatic and Effective Knowledge Graph Alignment enabled by Large Language Models

Rui Zhang, Yixin Su, Bayu Distiawan Trisedya et al.

The task of entity alignment between knowledge graphs (KGs) aims to identify every pair of entities from two different KGs that represent the same entity. Many machine learning-based methods have been proposed for this task. However, to our best knowledge, existing methods all require manually crafted seed alignments, which are expensive to obtain. In this paper, we propose the first fully automatic alignment method named AutoAlign, which does not require any manually crafted seed alignments. Specifically, for predicate embeddings, AutoAlign constructs a predicate-proximity-graph with the help of large language models to automatically capture the similarity between predicates across two KGs. For entity embeddings, AutoAlign first computes the entity embeddings of each KG independently using TransE, and then shifts the two KGs' entity embeddings into the same vector space by computing the similarity between entities based on their attributes. Thus, both predicate alignment and entity alignment can be done without manually crafted seed alignments. AutoAlign is not only fully automatic, but also highly effective. Experiments using real-world KGs show that AutoAlign improves the performance of entity alignment significantly compared to state-of-the-art methods.

In-Context Learning for Knowledge Base Question Answering for Unmanned Systems based on Large Language Models

Yunlong Chen, Yaming Zhang, Jianfei Yu et al.

Knowledge Base Question Answering (KBQA) aims to answer factoid questions based on knowledge bases. However, generating the most appropriate knowledge base query code based on Natural Language Questions (NLQ) poses a significant challenge in KBQA. In this work, we focus on the CCKS2023 Competition of Question Answering with Knowledge Graph Inference for Unmanned Systems. Inspired by the recent success of large language models (LLMs) like ChatGPT and GPT-3 in many QA tasks, we propose a ChatGPT-based Cypher Query Language (CQL) generation framework to generate the most appropriate CQL based on the given NLQ. Our generative framework contains six parts: an auxiliary model predicting the syntax-related information of CQL based on the given NLQ, a proper noun matcher extracting proper nouns from the given NLQ, a demonstration example selector retrieving similar examples of the input sample, a prompt constructor designing the input template of ChatGPT, a ChatGPT-based generation model generating the CQL, and an ensemble model to obtain the final answers from diversified outputs. With our ChatGPT-based CQL generation framework, we achieved the second place in the CCKS 2023 Question Answering with Knowledge Graph Inference for Unmanned Systems competition, achieving an F1-score of 0.92676.

Multi-teacher knowledge distillation as an effective method for compressing ensembles of neural networks

Konrad Zuchniak

Deep learning has contributed greatly to many successes in artificial intelligence in recent years. Today, it is possible to train models that have thousands of layers and hundreds of billions of parameters. Large-scale deep models have achieved great success, but the enormous computational complexity and gigantic storage requirements make it extremely difficult to implement them in real-time applications. On the other hand, the size of the dataset is still a real problem in many domains. Data are often missing, too expensive, or impossible to obtain for other reasons. Ensemble learning is partially a solution to the problem of small datasets and overfitting. However, ensemble learning in its basic version is associated with a linear increase in computational complexity. We analyzed the impact of the ensemble decision-fusion mechanism and checked various methods of sharing the decisions including voting algorithms. We used the modified knowledge distillation framework as a decision-fusion mechanism which allows in addition compressing of the entire ensemble model into a weight space of a single model. We showed that knowledge distillation can aggregate knowledge from multiple teachers in only one student model and, with the same computational complexity, obtain a better-performing model compared to a model trained in the standard manner. We have developed our own method for mimicking the responses of all teachers at the same time, simultaneously. We tested these solutions on several benchmark datasets. In the end, we presented a wide application use of the efficient multi-teacher knowledge distillation framework. In the first example, we used knowledge distillation to develop models that could automate corrosion detection on aircraft fuselage. The second example describes detection of smoke on observation cameras in order to counteract wildfires in forests.

Reformulation Techniques for Automated Planning: A Systematic Review

Diaeddin Alarnaouti, George Baryannis, Mauro Vallati

Automated planning is a prominent area of Artificial Intelligence, and an important component for intelligent autonomous agents. A cornerstone of domain-independent planning is the separation between planning logic, i.e. the automated reasoning side, and the knowledge model, that encodes a formal representation of domain knowledge needed to reason upon a given problem to synthesise a solution plan. Such a separation enables the use of reformulation techniques, which transform how a model is represented in order to improve the efficiency of plan generation. Over the past decades, significant research effort has been devoted to the design of reformulation techniques. In this paper, we present a systematic review of the large body of work on reformulation techniques for classical planning, aiming to provide a holistic view of the field and to foster future research in the area. As a tangible outcome, we provide a qualitative comparison of the existing classes of techniques, that can help researchers gain an overview of their strengths and weaknesses.

I Know What You Do Not Know: Knowledge Graph Embedding via Co-distillation Learning

Yang Liu, Zequn Sun, Guangyao Li et al.

Knowledge graph (KG) embedding seeks to learn vector representations for entities and relations. Conventional models reason over graph structures, but they suffer from the issues of graph incompleteness and long-tail entities. Recent studies have used pre-trained language models to learn embeddings based on the textual information of entities and relations, but they cannot take advantage of graph structures. In the paper, we show empirically that these two kinds of features are complementary for KG embedding. To this end, we propose CoLE, a Co-distillation Learning method for KG Embedding that exploits the complementarity of graph structures and text information. Its graph embedding model employs Transformer to reconstruct the representation of an entity from its neighborhood subgraph. Its text embedding model uses a pre-trained language model to generate entity representations from the soft prompts of their names, descriptions, and relational neighbors. To let the two model promote each other, we propose co-distillation learning that allows them to distill selective knowledge from each other's prediction logits. In our co-distillation learning, each model serves as both a teacher and a student. Experiments on benchmark datasets demonstrate that the two models outperform their related baselines, and the ensemble method CoLE with co-distillation learning advances the state-of-the-art of KG embedding.

Human-in-the-loop Handling of Knowledge Drift

Andrea Bontempelli, Fausto Giunchiglia, Andrea Passerini et al.

We introduce and study knowledge drift (KD), a complex form of drift that occurs in hierarchical classification. Under KD the vocabulary of concepts, their individual distributions, and the is-a relations between them can all change over time. The main challenge is that, since the ground-truth concept hierarchy is unobserved, it is hard to tell apart different forms of KD. For instance, introducing a new is-a relation between two concepts might be confused with individual changes to those concepts, but it is far from equivalent. Failure to identify the right kind of KD compromises the concept hierarchy used by the classifier, leading to systematic prediction errors. Our key observation is that in many human-in-the-loop applications (like smart personal assistants) the user knows whether and what kind of drift occurred recently. Motivated by this, we introduce TRCKD, a novel approach that combines automated drift detection and adaptation with an interactive stage in which the user is asked to disambiguate between different kinds of KD. In addition, TRCKD implements a simple but effective knowledge-aware adaptation strategy. Our simulations show that often a handful of queries to the user are enough to substantially improve prediction performance on both synthetic and realistic data.

El padre, el hijo y la hija

Nicolás Sebastián Sánchez

Las posiciones de Brandom y Millikan se comparan con respecto a sus orígenes comunes en las obras de Wilfrid Sellars y Wittgenstein. Millikan toma más seriamente los temas de “figuración” de Sellars y Wittgenstein. Brandom sigue a Sellars más de cerca en derivar la normatividad del lenguaje de la práctica social, si bien hay también indicios en Sellars de una derivación posible a partir de la teoría evolutiva. Una importante tesis común a Brandom y Millikan es que no hay representaciones sin función o “actitud”.

Accontentarsi semplicemente di esistere. Artaud interprete di Van Gogh

Vanessa Pietrantonio

Non si può certo negare che l’associazione tra genialità e follia abbia finito per costituire, nel corso dei secoli, uno tra i topoi ricorrenti in tutti gli ambiti della fenomenologia artistica: diventando un abbinamento così diffuso e abusato da dissolvere la sua nobile genealogia filosofica (che affonda le radici nella divina “mania” platonica e nello spirito “melanconico” isolato, per primo, da Aristotele) in un vero e proprio luogo comune, depotenziato di qualsiasi vigore semantico. È, senza dubbio, il caso di Van Gogh: incarnazione di una genialità artistica che si innesta, senza alcuna mediazione, sul tronco di un disagio psichico diagnosticato dalla psichiatria dell’epoca come espressione incontestabile di alienazione mentale.

QMA-hardness of Consistency of Local Density Matrices with Applications to Quantum Zero-Knowledge

Anne Broadbent, Alex B. Grilo

We provide several advances to the understanding of the class of Quantum Merlin-Arthur proof systems (QMA), the quantum analogue of NP. Our central contribution is proving a longstanding conjecture that the Consistency of Local Density Matrices (CLDM) problem is QMA-hard under Karp reductions. The input of CLDM consists of local reduced density matrices on sets of at most k qubits, and the problem asks if there is an n-qubit global quantum state that is consistent with all of the k-qubit local density matrices. The containment of this problem in QMA and the QMA-hardness under Turing reductions were proved by Liu [APPROX-RANDOM 2006]. Liu also conjectured that CLDM is QMA-hard under Karp reductions, which is desirable for applications, and we finally prove this conjecture. We establish this result using the techniques of simulatable codes of Grilo, Slofstra, and Yuen [FOCS 2019], simplifying their proofs and tailoring them to the context of QMA. In order to develop applications of CLDM, we propose a framework that we call locally simulatable proofs for QMA: this provides QMA proofs that can be efficiently verified by probing only k qubits and, furthermore, the reduced density matrix of any k-qubit subsystem of an accepting witness can be computed in polynomial time, independently of the witness. Within this framework, we show advances in quantum zero-knowledge. We show the first commit-and-open computational zero-knowledge proof system for all of QMA, as a quantum analogue of a "sigma" protocol. We then define a Proof of Quantum Knowledge, which guarantees that a prover is effectively in possession of a quantum witness in an interactive proof, and show that our zero-knowledge proof system satisfies this definition. Finally, we show that our proof system can be used to establish that QMA has a quantum non-interactive zero-knowledge proof system in the secret parameter setting.

Accurate Electron Affinities and Orbital Energies of Anions from a Non-Empirically Tuned Range-Separated Density Functional Theory Approach

Lindsey N. Anderson, M. Belén Oviedo, Bryan M. Wong

The treatment of atomic anions with Kohn-Sham density functional theory (DFT) has long been controversial since the highest occupied molecular orbital (HOMO) energy, $E_{HOMO}$, is often calculated to be positive with most approximate density functionals. We assess the accuracy of orbital energies and electron affinities for all three rows of elements in the periodic table (H-Ar) using a variety of theoretical approaches and customized basis sets. Among all of the theoretical methods studied here, we find that a non-empirically tuned range-separated approach (constructed to satisfy DFT-Koopmans' theorem for the anionic electron system) provides the best accuracy for a variety of basis sets - even for small basis sets where most functionals typically fail. Previous approaches to solve this conundrum of positive $E_{HOMO}$ values have utilized non-self-consistent methods; however electronic properties, such as electronic couplings/gradients (which require a self-consistent potential and energy), become ill-defined with these approaches. In contrast, the non-empirically tuned range-separated procedure used here yields well-defined electronic couplings/gradients and correct $E_{HOMO}$ values since both the potential and resulting electronic energy are computed self-consistently. Orbital energies and electron affinities are further analyzed in the context of the electronic energy as a function of electronic number (including fractional numbers of electrons) to provide a stringent assessment of self-interaction errors for these complex anion systems.
