Data preprocessing or cleansing is one of the biggest hurdles in industry for developing successful machine learning applications. The process of data cleansing includes data imputation, feature normalization & selection, dimensionality reduction, and data balancing applications. Currently such preprocessing is manual. One approach for automating this process is meta-learning. In this paper we ...

In this work, the extent of natural cleansing effect rainfall, wind and fog or a combination these on an insulator string were investigated. Results showed that pollution losses progress with time, considerable fraction occurring within 15 minutes testing. While alone played little no role in surface cleansing, it increases by rainfall. The topsides insulators found to be more affected compared...

One of the motivations for research in data quality is to automatically identify cleansing activities, namely a sequence of actions able to cleanse a dirty dataset, which today are often developed manually by domain-experts. Here we explore the idea that AI Planning can contribute to identify data inconsistencies and automatically fix them. To this end, we formalise the concept of cost-optimal ...

BACKGROUND Various solutions have been recommended for cleansing wounds, however normal saline is favoured as it is an isotonic solution and does not interfere with the normal healing process. Tap water is commonly used in the community for cleansing wounds because it is easily accessible, efficient and cost effective, however, there is an unresolved debate about its use. OBJECTIVES The objec...

BACKGROUND Metal pins are used to apply skeletal traction or external fixation devices in the management of orthopaedic fractures. These pins protrude through the skin (described as 'percutaneous') and the way in which they are treated after insertion may affect the incidence of pin site infection. This review set out to summarise the evidence on the effect of pin site care on infection rates. ...

BACKGROUND Wound cleansing should create an optimal healing environment by removing excess debris, exudates, foreign and necrotic material which are commonly present in the wounds that heal by secondary intention. At present, there is no research evidence for whether pressurised irrigation has better wound healing outcomes compared with conventional swabbing practice in cleansing wound. OBJEC...
