Fiscal decentralization and development: How crucial is local politics?

Does fiscal decentralization in a politically decentralized less developed country help strengthen democratic institutions at the grass root level? And is the impact of such decentralization on local politics important in determining local development? Our study on Indonesia suggests that fiscal decentralization enhanced free and fair local elections, though the incidence of elite capture, and the consequent breakdown of local democracy, was also present in significant proportions. Fiscal decentralization promoted development mostly in communities which transited out from elite capture to embrace free and fair elections. This was followed by communities that experienced the emergence of elite capture. Communities that continued to remain under either elite capture or free and fair elections did the worst. These findings suggest that while the emergence of elite capture exists, it may not necessarily be the most harmful. Instead, and surprisingly so, stability of local polity hurts development the most

Land cover classification using fuzzy rules and aggregation of contextual information through evidence theory

Land cover classification using multispectral satellite image is a very challenging task with numerous practical applications. We propose a multi-stage classifier that involves fuzzy rule extraction from the training data and then generation of a possibilistic label vector for each pixel using the fuzzy rule base. To exploit the spatial correlation of land cover types we propose four different information aggregation methods which use the possibilistic class label of a pixel and those of its eight spatial neighbors for making the final classification decision. Three of the aggregation methods use Dempster-Shafer theory of evidence while the remaining one is modeled after the fuzzy k-NN rule. The proposed methods are tested with two benchmark seven channel satellite images and the results are found to be quite satisfactory. They are also compared with a Markov random field (MRF) model-based contextual classification method and found to perform consistently better.Comment: 14 pages, 2 figure

Visual Imitation Learning with Recurrent Siamese Networks

It would be desirable for a reinforcement learning (RL) based agent to learn behaviour by merely watching a demonstration. However, defining rewards that facilitate this goal within the RL paradigm remains a challenge. Here we address this problem with Siamese networks, trained to compute distances between observed behaviours and the agent's behaviours. Given a desired motion such Siamese networks can be used to provide a reward signal to an RL agent via the distance between the desired motion and the agent's motion. We experiment with an RNN-based comparator model that can compute distances in space and time between motion clips while training an RL policy to minimize this distance. Through experimentation, we have had also found that the inclusion of multi-task data and an additional image encoding loss helps enforce the temporal consistency. These two components appear to balance reward for matching a specific instance of behaviour versus that behaviour in general. Furthermore, we focus here on a particularly challenging form of this problem where only a single demonstration is provided for a given task -- the one-shot learning setting. We demonstrate our approach on humanoid agents in both 2D with $10$ degrees of freedom (DoF) and 3D with $38$ DoF.Comment: PrePrin
