People power: Factual, ambitious, over-optimistic?

Processing Transactions over Optimistic Atomic Broadcast Protocols

Atomic broadcast primitives allow fault-tolerant cooperation between sites in a distributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, scalable applications on top of atomic broadcast primitives. Recently, a new approach has been proposed which, based on optimistic assumptions about the communication system, redu...

Question Answering over Knowledge Base using Factual Memory Networks

In the task of question answering, Memory Networks have recently shown to be quite effective towards complex reasoning as well as scalability, in spite of limited range of topics covered in training data. In this paper, we introduce Factual Memory Network, which learns to answer questions by extracting and reasoning over relevant facts from a Knowledge Base. Our system generate distributed repr...

Mercosur: Ambitious Policies, Poor Practices

Mercosur has achieved important advances like the removal of intrabloc tariff and non-tariff barriers and the establishment of a common external tariff for most products. However, its ambitious plans to deepen the integration process comprising harmonisation of policies in areas like competition policy, government procurement, technical barriers and phytosanitary measures have not been implemen...

Distributed Optimistic Concurrency Considered Optimistic

Optimistic concurrency relies on speculative execution, read-write conflict detection, and checkpointrollback techniques to provide a programming model that replaces locks with the abstraction of atomic, isolated execution of critical sections. Previous research has shown that on chip multi-processors, a class of workloads featuring irregular parallelism and rare read-write conflicts can reap s...
