ICML. They are split into two categories, classification and regression, based on the type of the field we are trying to predict. Change ), You are commenting using your Twitter account. Abalones, also called ear-shells or sea ears, are sea snails (marine gastropod mollusks) found world-wide. 4177 Text Regression 1995 Marine Research Laboratories – Taroona Zoo Dataset Artificial dataset covering 7 classes of animals. [View Context].Bernhard Pfahringer and Hilan Bensusan. 2500 . Classification, Clustering . The Abalone Dataset involves predicting the age of abalone given objective measures of individuals. A brief aside on the motivation behind collecting the dataset. Predicting the age of abalone from physical measurements. Task: Classification; DATASET CSV ATTRIBUTES CSV. Features measured include length, width and weight of the abalone as well as its sex. In this section you can download some files related to the abalone data set: The complete data set already formatted in KEEL format can be downloaded from here. The hard-margin linear SVM classifier predictably gave very poor results (despite using one-vs-one multi-class classification) because of the overlap between the classes. 2003. From the original data examples with missing values were removed (the majority having the predicted value missing), and the ranges of the continuous values have been scaled for use with an ANN (by dividing by 200). Most machine learning algorithms work best when the number of samples in each class are about equal. Automatic Derivation of Statistical Algorithms: The EM Family and Beyond. Warped Gaussian Processes. beginner x 23735. audience > beginner, regression. [View Context].C.

The soft-margin RBF-kernelized SVM classifier gave much better results. Division of Informatics Gatsby Computational Neuroscience Unit University of Edinburgh University College London. 2002.

[Web Link]David Clark, Zoltan Schreter, Anthony Adams "A Quantitative Comparison of Dystal and Backpropagation", submitted to the Australian Conference on Neural Networks (ACNN'96). 2000. Department of Computer Science and Information Engineering National Taiwan University. Because of the weird regression-classification entanglement, the multi-classifier will have to take into account the linear arrangement of the 3 classes. Table 1. Using Correspondence Analysis to Combine Classifiers. Abalone Dataset. NIPS. Change ), You are commenting using your Google account. Subset Based Least Squares Subspace Regression in RKHS. NIPS. Feature selection could really help here. Instead, all the training data points are taken into accounted, but weighted by proximity to the test data point. Multivariate, Text, Domain-Theory . Sources: ... (ACNN'96). 2002. 101 Text Classification 1990 R. Forsyth The number of observations for each class is not balanced. ( Log Out / An abalone is an edible mollusk of warm seas that has a shallow ear-shaped shell lined with mother-of-pearl and pierced with respiratory holes. Speeding Up Fuzzy Clustering with Neural Network Techniques. The formula is √(x2−x1)²+(y2−y1)²+(z2−z1)² …… (n2-n1)² It is a multi-class classification problem, but can also be framed as a regression. This dataset consists of 4177 samples with an age distribution as shown here. General and Efficient Multisplitting of Numerical Attributes. Decision tree builds regression or classification models in the form of a tree structure. However, there are some interesting peculiarities to this dataset compared to other simpler classification datasets: I ran this dataset through my earlier algorithms – Bayes Plug-in, Naive Bayes, Perceptron – and finally also implemented the gradient Logistic Regression algorithm as well as the Support Machine Vector algorithm. This dataset should ideally be treated as a regression task, since it attempts to predict the age of the Abalone. By simple using this formula you can calculate distance between two points no matter how many attributes or properties you are given like height, breadth, width, weight and so on upto n where n could be the last property of the object you have. [View Context].Johannes Furnkranz. A. K Suykens and J. Vandewalle and Bart De Moor. With the Gaussian Bayes classifier, the test accuracy obtained is around 61.2% which is not too much worse than the other classifiers I tried later (nor compared to the results reported by the original investigators of the dataset.) Proceedings of the ICML-99 Workshop: From Machine Learning to. Data binarization by discriminant elimination. This dataset helps you predict the age of this mollusk. Ilhan Uysal and H. Altay Guvenir.

Buntine. [View Context].Miguel Moreira and Alain Hertz and Eddy Mayoraz. Looking at some of the features’ histograms, it does appear than there is considerable overlap in the classes, especially in the second two classes (red and green). [View Context].. ; A copy of the data set already partitioned by means of a 10-folds cross validation procedure can be downloaded from here. [View Context].Edward Snelson and Carl Edward Rasmussen and Zoubin Ghahramani. [View Context].Nir Friedman and Iftach Nachman. Xoogler exploring Machine learning. [View Context].Christopher J. Merz. Curse of dimensionality: kNN suffers from the problem of sparseness when too many features/axes are in play. A soft-margin linear SVM using one-vs-one classification also performed pretty well. For my second dataset in this series, I picked another classification dataset, the Abalone dataset. It turns out there’s a lot of overlap amongst the classes, thereby making classification inherently limited. The dataset contains a set of measurements of abalone, a type of sea snail. Don’t get intimidated by the name, it just simply means the distance between two points in a plane. Complete Cross-Validation for Nearest Neighbor Classifiers. Australian Conference on Artificial Intelligence. Austrian Research Institute for Artificial Intelligence. ( Log Out / 2002. Moreover, abalone sometimes form the so-called ’stunted’ populations which have their growth characteristics very different from other abalone populations . 1.

It breaks down a dataset into smaller subsets and the tree is developed subsequently. [View Context].Khaled A. Alsabti and Sanjay Ranka and Vineet Singh. Other measurements, which are easier to obtain, are used to predict the age.
