Modeling Interference Via Symmetric Treatment Decomposition
September 4, 2017

Statistics
Methodology
Classical causal inference assumes treatments meant for a given unit do not
have an effect on other units. This assumption is violated in interference
problems, where new types of spillover causal effects arise, and causal
inference becomes...
Amalgamation and Symmetry: From Local to Global Consistency in The
Finite
August 31, 2017
Mathematics
Combinatorics
We present a generic construction of finite realisations of amalgamation
patterns. An amalgamation pattern is specified by a finite collection of finite
template structures together with a collection of partial isomorphisms between
them. A ...

Computation and Language
The generation of complex derived word forms has been an overlooked problem
in NLP; we fill this gap by applying neural sequence-to-sequence models to the
task. We overview the theoretical motivation for a paradigmatic treatment of
derivati...
Even for common NLP tasks, sufficient supervision is not available in many
languages -- morphological tagging is no exception. In the work presented here,
we explore a transfer learning scheme, whereby we train character-level
recurrent neu...
Stability results of octahedrality in tensor product spaces

Functional Analysis
We prove that there exists a finite-dimensional Banach space X such that
L1C([0,1])⊗εX fails the strong diameter
two property and L∞C([0,1])⊗πX∗ fails to
have o...

Quantum Physics
Scholars of the history and philosophy of science have asked what would
decolonized science would look like. This paper develops an answer by
interrogating the assumption that observations need to be recorded and
communicated using the lang...

Let W be an affine Weyl group, and let k be a field of characteristic
p>0. The diagrammatic Hecke category D for W over k is a
categorification of the Hecke algebra for W with rich connections to modular
repr...
Promotion through Connections: Favors or Information?

Connections appear to be helpful in many contexts, such as obtaining a job, a
promotion, a grant, a loan, or publishing a paper. This may be due either to
favoritism or to information conveyed by connections. Attempts at identifying
both ef...
Studies on the Pea Pattern Sequence
August 21, 2017
Mathematics
History and Overview
In this paper we formally define the family of sequences know as "Pea
Pattern". We then analyse its behaviour and conditions for fixed and periodic
points. The paper ends with a list of fixed points and cycles....
Gyrokinetic Field Theory as a Gauge Transform or: gyrokinetic theory
without Lie transforms
August 21, 2017

Plasma Physics
Gyrokinetic theory is a basis for treating magnetised plasma dynamics slower
than particle gyrofrequencies where the scale of the background is larger than
relevant gyroradii. The energy of field perturbations can be comparable to the
therm...
