Inductive learning in Shared Neural Multi-Spaces

The learning of rules from examples is of continuing interest to machine learning since it allows generalization from fewer training ex- amples. Inductive Logic Programming (ILP) generates hypothetical rules (clauses) from a knowledge base augmented with (positive and negative) examples. A successful hypothesis entails all positive examples and does not entail any negative example. The Shared Neural Multi-Space (Shared NeMuS) structure encodes first order expressions in a graph suitable for ILP-style learning. This paper explores the NeMuS structure and its re- lationship with the Herbrand Base of a knowledge-base to generate hy- potheses inductively. It is demonstrated that inductive learning driven by the knowledge-base structure can be implementated successfully in the Amao cognitive agent framework, including the learning of recursive hypotheses

Influence of spray mixture volume and flight height on herbicide deposition in aerial applications on pastures

The objective of the present study was to analyze the influence of spray mixture volume and flight height on herbicide deposition in aerial applications on pastures. The experimental plots were arranged in a pasture area in the district of Porto Esperidião (Mato Grosso, Brazil). In all of the treatments, the applications contained the herbicides aminopyralid and fluroxypyr (Dominum) at the dose of 2.5 L c.p. ha-1, including the adjuvant mineral oil (Joint Oil) at the dose of 1.0 L and a tracer to determine the deposition by high-performance liquid chromatography (HPLC) (rhodamine at a concentration of 0.6%). The experiment consisted of nine treatments that comprised the combinations of three spray volumes (20, 30 and 50 L ha-1) and three flight heights (10, 30 and 40 m). The results showed that, on average, there was a tendency for larger deposits for the smallest flight heights, with a significant difference between the heights of 10 and 40 m. There was no significant difference among the deposits obtained with the different spray mixture volumes.O objetivo do presente estudo foi analisar a influência do volume de calda e da altura de voo na deposição em aplicações aéreas de herbicidas em áreas de pastagens. Para a montagem das parcelas experimentais, foi escolhida uma área com pastagens no município de Porto Esperidião-MT. Em todos os tratamentos, as aplicações foram realizadas utilizando os herbicidas aminopiralide e fluroxipir (Dominum) na dose de 2,5 L p.c. ha-1, incluindo o adjuvante óleo mineral (Joint Oil) na dose de 1,0 Lha-1 e um traçante para determinação da deposição por cromatografia HPLC (rodamina, na concentração de 0,6%). O ensaio considerou nove tratamentos que consistiram nas combinações de três volumes de calda (20, 30 e 50Lha-1) e três alturas de voo (10, 30 e 40 m). Os resultados mostraram que, em média, houve tendência de maiores depósitos para as menores alturas de voo, com diferença significativa entre 10 e 40 m de altura. Não houve diferença significativa entre os depósitos obtidos com os diferentes volumes de calda
