Accurate estimation of ego-motion heavily relies on correct point correspondences in the context of visual odometry. In order to ensure a metric reconstruction of camera motion, we can refer to the 3D structure of the scene. In this paper we present an indicator for evaluating the accuracy of stereo-based 3D point measurements as well as for filtering out low-confidence correspondences for ego-...

The Sinhala volitive/involitive contrast is characterized by verb stem and subject case marking alternations, and broadly indicates the volitionality/non-volitionality of the subject, plus other co-varying features. While superficially a high/low transitivity split à la Hopper and Thompson (1980), we argue that the distinction actually emerges from the interaction of just two factors: a realis/...

We shed some light on the problem of determining the orbits of the braid group action on semiorthonormal bases of Mukai lattices as considered in [7] and [8]. We show that there is an algebraic (and in particular algorithmic) equivalence between this problem and the Hurwitz problem for integer matrix groups finitely generated by involutions. In particular we consider the case of K0(P n) n > 4 w...

An important source of high clustering coefficient in real-world networks is transitivity. However, existing approaches for modeling transitivity suffer from at least one of the following problems: i) they produce graphs from a specific class like bipartite graphs, ii) they do not give an analytical argument for the high clustering coefficient of the model, and iii) their clustering coefficient...

In response to Block and Barnett (2012), this paper clarifies some misunderstandings about the concept of transitivity and shows its relation to rationality, asynchronicity of choice, and indifference analysis. It is demonstrated that Block and Barnett, contrary to their self-interpretation, do not in fact attack transitivity but the assumption of stable preferences. It is argued that the stabi...

Systemic Functional Linguistics provides a semiotic perspective on language. The text analysis described in Systemic Functional Linguistics (SFL) can be of critical value in real-world applications. But parsing with SFL grammars is computationally intensive task and parsers for this level of description to date have not been able to operate on unrestricted input. This paper describes a graph-ba...

In this paper we show that the widely used normalization constraint ∑ n i=1 wi = 1 does not apply to the priority vectors associated with reciprocal relations, whenever additive transitivity is involved. We show that misleading applications of this type of normalization may lead to unsatisfactory results and we give some examples from the literature. Then, we propose an alternative normalizatio...

Quantum causal histories are defined to be causal sets with Hilbert spaces attached to each event and local unitary evolution operators. The reflexivity, antisymmetry, and transitivity properties of a causal set are preserved in the quantum history as conditions on the evolution operators. A quantum causal history in which transitivity holds can be treated as “directed” topological quantum fiel...

Given a C2− Anosov diffeomorphism f:M→M, we prove that the Jacobian condition Jfn(p)=1, for every point p such fn(p)=p, implies transitivity. As application in celebrated theory of Sinai-Ruelle-Bowen, this result allows us to state classical theorem Livsic-Sinai without directly assuming transitivity as general hypothesis. A special consequence our is C2-Anosov diffeomorphism, which regular, in...

This paper is a step towards a systematic theory of the transitivity (clustering) phenomenon in random networks. A static framework is used, with adjacency matrix playing the role of the dynamical variable. Hence, our model is a matrix model, where matrices are random, but their elements take values 0 and 1 only. Confusion present in some papers where earlier attempts to incorporate transitivit...
