EC90-1762 Nut Tree Cultivars for Nebraska

Proper nut cultivar (variety) selection is important for successful and satisfying results from the home gardener's efforts. Selection should be determined by personal preferences, available space, and intended use of the nuts. Harvest can be spread over several weeks if cultivars with different periods of maturity are planted. It is important that homeowners select the nut plants or cultivars best adapted for cultivation in their area of the state. This extension circular covers how to select a nut cultivar, the plant hardiness zones, horticultural regions, and length of growing season. It contains a list of all nut cultivars suited for growing in the state of Nebraska.

An Extended Kernel for Generalized Multiple-Instance Learning

The multiple-instance learning (MIL) model has been successful in areas such as drug discovery and content-based image-retrieval. Recently, this model was generalized and a corresponding kernel was introduced to learn generalized MIL concepts with a support vector machine. While this kernel enjoyed empirical success, it has limitations in its representation. We extend this kernel by enriching its representation and empirically evaluate our new kernel on data from content-based image retrieval, biological sequence analysis, and drug discovery. We found that our new kernel generalized noticeably better than the old one in content-based image retrieval and biological sequence analysis and was slightly better or even with the old kernel in the other applications, showing that an SVM using this kernel does not overfit despite its richer representation.
