The Best Separating Decision Tree Twin Support Vector Machine for Multi-Class Classification

The Best Separating Decision Tree Twin Support Vector Machine for Multi-Class Classification

Support vector machines (SVMs), being computationally powerful tools for supervised learning [1–3], have already outperformed most other systems in a wide variety of applications [4–6]. As a million stone of the SVM, twin support vector machine (TWSVM) [7] determines two nonparallel hyeperplanes such that each hyperplane is closer to one of two classes and as far as possible from the other one, which has been studied wildly in recently. The preliminary TWSVMs [7–9] design for binary class classification problem. The binary TWSVMs are excellent at dealing with some certain probability model data (such as “Cross Planes” data) with less training time. Thus, the methods of constructing the nonparallel hyperplanes have been studied extensively [10–16].

Advance Probabilistic Binary Decision Tree using SVM

Advance Probabilistic Binary Decision Tree using SVM

Madzarov et al.[5] is presented a novel architecture of Support Vector Machine classifiers utilizing binary decision tree(SVM-BDT) for solving multiclass problem. Design the hierarchy of binary decision subtask using SVMs with clustering algorithm. The clustering model utilizes distance measures at the kernel space instead of input space. The experimental result indicates that the training phase of SVM- BDT is faster while comparing better accuracy with other SVM based approaches, ensembles of tree(Bagging and random forest) and neural network. During the testing phase, due to its logarithmic complexity, SVM-BDT is much faster than widely used multi-class SVM methods like OaO and OaA.

Advanced Probabilistic Binary Decision Tree Using SVM for large class problem

Advanced Probabilistic Binary Decision Tree Using SVM for large class problem

The APBDT-SVM is providing better multiclass classification performance. Utilizing a decision tree architecture with a probabilistic output of SVM takes much less computation for deciding that in which class unknown sample is placed. Here proposed a new and original technique that combines Binary Decision Tree and SVM associate with a sigmoid function(PSVM) to estimate the probability of membership to each sub-groups. Probabilistic function for each leaf are built after traversing each nodes and leaves. It is critical to have proper structuring for the better performance of APBDT-SVM. After analyzing other multiclass methods like OaO, OaA, BDT and DAG we conclude that APBDT-SVM provides better classification accuracy. APBDT-SVM also provides better result in training and testing time compare to other multiclass methods. The result shows that APBDT is accurate and efficient method as an other multiclass method. APBDT-SVM lead to a dramatic improvement in recognition speed when addressing problems with maximum number of classes.

Cache Oblivious Search Trees via Binary Trees of Small Height

Cache Oblivious Search Trees via Binary Trees of Small Height

Our approach is to embed a dynamic tree in a static complete tree by maintaining a height bound of log n + O(1) for the dynamic tree, where n is its current size. It follows that the dynamic tree can be embedded in a complete tree of height log n + O(1) and size O(n). Whenever n has doubled, we create a new static tree. The following subsections are devoted to tree rebalancing schemes achieving height log n + O(1). Our scheme is very similar to the tree balancing scheme of Andersson [2] and to the scheme of Itai et al. [14] for supporting insertions into the middle of a file. Bender et al. [5] used a similar scheme in their cache oblivious search trees, but used it to solve the “packed-memory problem”, rather than directly to maintain balance in a tree. Note that the embedding of a dynamic tree in a complete tree implies that we cannot use rebalancing schemes which are based on rotations, or, more generally, schemes allowing subtrees to be moved by just changing the pointer to the root of the subtree, as e.g. is the case in the rebalancing scheme of Fagerberg [10] achieving height ⌈log n + o(1)⌉.

Single decision tree classifiers' accuracy on medical data

Single decision tree classifiers' accuracy on medical data

ABSTRACT. Decision tree is one of the classification techniques for classi- fying sequential decision problems such as those in medical domain. This paper discusses an evaluation study on different single decision tree classifi- ers. There are various single decision tree classifiers which have been ex- tensively applied in medical decision making; each of these classifies the data with different accuracy rate. Since accuracy is crucial in medical deci- sion making, it is important to identify a classifier with the best accuracy. The study examines the performance of fourteen single decision tree classi- fiers on three medical data sets, i.e. Wisconsin’s breast cancer data sets, Pi- ma Indian diabetes data sets and hepatitis data sets. All classifiers were trained and tested using WEKA and cross validation. The results revealed that classifiers such as FT, LMT, NB tree, Random Forest and Random Tree are the five best single classifiers as they constantly provide better accuracy in their classifications.

Margin Trees for High-dimensional Classification

Margin Trees for High-dimensional Classification

Table 4 shows the results of applying the margin tree classifier (complete linkage) with feature selection, on the data sets described earlier. Tenfold cross-validation was used to choose the margin fraction parameter α, and both CV error and test set error are reported in the table. Also shown are results for nearest shrunken centroids (Tibshirani et al., 2001), using cross-validation to choose the shrinkage parameter. This method starts with centroids for each class, and then shrinks them towards the overall centroid by soft-thresholding. We see that (a) hard thresholding generally improves upon the error rate of the full margin tree; (b) margin trees outperform nearest shrunken centroids on the whole, but not in every case. In some cases, the number of genes used has dropped substantially; to get smaller number of genes one could look more closely at the cross-validation curve, to check how quickly it was rising.

Syntactic Decision Tree LMs: Random Selection or Intelligent Design?

Syntactic Decision Tree LMs: Random Selection or Intelligent Design?

In Section 2, we describe the details of the syntac- tic decision tree LM. Construction of a single-tree model is difficult due to the inevitable greediness of the tree construction process and its tendency to overfit the data. This problem is often addressed by interpolating with lower order decision trees. In Sec- tion 3, we point out the inappropriateness of backoff methods borrowed from n-gram models for decision tree LMs and briefly describe a generalized interpo- lation for such models. The generalized interpola- tion method allows the addition of any number of trees to the model, and thus raises the question: what is the best way to create diverse decision trees so that their combination results in a stronger model, while at the same time keeping the total number of trees in the model relatively low for computational practical- ity. In Section 4, we explore and evaluate a variety

Improving logic-level representation of taylor expansion diagram using attributed edges

Improving logic-level representation of taylor expansion diagram using attributed edges

Most formal verification tools need a design to be converted to a canonical data structure in order for the formal verification algorithms to be used. Several data structures have been proposed to address this need, however none of them, with the exception of TED [1-3], can handle designs at the vector-level. Therefore, formal verification tools today do make use of bit-level representation for capturing a design, and therefore have limitations in processing large designs. On the other hand, a graph-based representation for designs at the RT-level, coupled with efficient algorithms, provides a mechanism for handling large designs. However, TED, which has a good performance in representing vector-level designs, is not good at representing Boolean expressions. Therefore, TED is not efficient for representing designs at the RT-level. In fact, RT-level designs consist of both vector-level and logic-level parts. Many parts of an RT-level design including its controller may be described by Boolean expressions. So, in addition to a good vector- level representation, having a good Boolean function manipulation is essential for an RT-level data structure. The focus of this paper is to introduce Attributed TED, a high-level graph-based representation for the manipulation of RT-level descriptions. This representation is based on TED. This paper addresses the mentioned shortcomings of TED for achieving a better data structure for RT-level representation and formal verification. Experimental results demonstrate that Attributed TED yields better performance than TED using a number of benchmark circuits.

A Study of Non Linear Data Structure: Red Black Tree

A Study of Non Linear Data Structure: Red Black Tree

ABSTRACT: Trees are widely used abstract data type or we can say trees are the data structure that implementing abstract data type. The reason behind to use the trees are that whenever we want to store information in forms of hierarchy we can use trees. Trees provide the moderate insertion/ deletion but quicker than arrays and slower than unordered linked lists. Trees don’t have an upper limit on number of nodes as nodes are linked using pointers. Binary trees are special case of tree where every node has almost two children. Binary search tree is a node-based binary tree data structure in which left sub tree of a node contains nodes with key value less than the root node key and right sub tree that contains nodes with key value greater than root key. Binary Search Tree provides moderate access or search and it is quicker than linked list but slower than arrays .With the binary search tree, tree shape depends on insertions order and that can be degenerated. So, with binary search tree we can’t guarantee efficient insertion and retrieval. Finally we look at red-black trees, a variation of binary search trees that overcome binary search tree’s limitations through a logarithmic bound on insertion and retrieval.

Using Two Dimensional Hybrid Feature Dataset to Detect Malicious Executables

Using Two Dimensional Hybrid Feature Dataset to Detect Malicious Executables

In [1] authors have introduced new data mining approach to detect malicious executable rather than traditional heuristic approach which was more costly and ineffective. Using data mining framework they found out patterns which detected malicious binaries. Thus doubling the detection rate compared to traditional signature based approach. [2] We are introduced with static techniques to detect malware using techniques of information gain (IG) and principle component analysis (PCA). In [3] authors have described a hybrid model to detect malicious executable, where they have used three feature set to create a dataset. They are as follows:-i] Binary n-gram, ii] Derived Assembly Features (DAF), iii] Dynamic Link Library (DLL) calls. They use this features to train classifier and then trained classifier is used to test on unseen malicious executables. Here in [4] authors have combined machine learning techniques with data mining techniques. They have gathered numerous training samples and processed it. After this is done they have selected only relevant features for prediction and evaluated variety of methods like Naïve Bayes, Boosted decision tree. In [5] authors use techniques of sliding window to select n-grams as per the value of n taken. We select n-gram of malware instances to classify it correctly. They have mentioned how to reduce large data size and dimensions.

Multiclass Cancer Classification by Using Fuzzy Support Vector Machine and Binary Decision Tree With Gene Selection

Multiclass Cancer Classification by Using Fuzzy Support Vector Machine and Binary Decision Tree With Gene Selection

We investigate the problems of multiclass cancer classification with gene selection from gene expression data. Two different con- structed multiclass classifiers with gene selection are proposed, which are fuzzy support vector machine (FSVM) with gene selection and binary classification tree based on SVM with gene selection. Using F test and recursive feature elimination based on SVM as gene selection methods, binary classification tree based on SVM with F test, binary classification tree based on SVM with recursive feature elimination based on SVM, and FSVM with recursive feature elimination based on SVM are tested in our experiments. To accelerate computation, preselecting the strongest genes is also used. The proposed techniques are applied to analyze breast cancer data, small round blue-cell tumors, and acute leukemia data. Compared to existing multiclass cancer classifiers and binary classifi- cation tree based on SVM with F test or binary classification tree based on SVM with recursive feature elimination based on SVM mentioned in this paper, FSVM based on recursive feature elimination based on SVM can find most important genes that affect certain types of cancer with high recognition accuracy.

A novel trio combo strategy for efficient team formation using hybrid triangulation mechanism

In the fast growing world understanding a situation is highly dynamic process. The decisions are to be made in an instantaneous fashion following different stages of risk and ambiguity. Project managers and leaders are forced to make such critical decisions that change the effect of the company. One such critical decision that involves rationalism and logical diagnosing is the process of choosing a feasible employee for a given project. The main objective of this research work is to propose strategies for optimally electing employees for an effective team formation and to understand the relationship between team’s success and given project’s success. The method adopted for achieving the central theme of the article is to develop a novel research model that wraps three dominant machine learning approaches to form a triangular hybridization for a better quality team formation. The three methods inspired are Artificial Neural Network (ANN), Decision Tree (DT), and a proposed method called Ensemble Decision Tree (EDT) which is a boosted decision tree using logit boost algorithm that are embedded into the proposed research model for achieving the desired goal. As a pilot scale attempt the model is validated by training and testing it over 474 freelancers from leading sites. The results infer that there exist a direct dependence of team and project success and the proposed EDT approach outperforms other two methods yielding an accuracy of about 87.34% in predicting the unknown sample as a valid or an invalid agent for the current project under consideration.

Analysis of Cardiotocogram Data for Fetal Distress Determination by Decision Tree Based Adaptive Boosting Approach

Analysis of Cardiotocogram Data for Fetal Distress Determination by Decision Tree Based Adaptive Boosting Approach

The analysis results are very promising as for comparing with the related works. As stated earlier Huang and Hsu [2] analyzed the same data and reached the results showing that the accuracies of DA, DT and ANN are 82.1%, 86.36% and 97.78% respectively, and 80%, 10%, and the remaining 10% of the whole dataset were ran- domly used for training, testing, and validation respectively. ANN result of 97.78% accuracy doesn’t outperform our decision tree based AdaBoost result of 95.01%, because in this study not a part of data is selected for test, but 10-fold cross validation technique is used for stability. Another admirable study [5] analyzed the same data by least squares support vector machine (LS-SVM) utilizing a binary decision tree, optimizing the parameters by PSO, they reached a classification accuracy rate of 91.62%, again outperformed by AdaBoost ensemble with base classifiers of decision trees.

Design and Simulation of Binary Tree Comparators using Constant Delay Logic in 180nm Technology

Design and Simulation of Binary Tree Comparators using Constant Delay Logic in 180nm Technology

The binary tree based comparator structure can be divided into two stages, where the first stage includes eight 2 bit comparators in parallel along with encoding circuitries. The second stage consists of a single 8 bit comparator. The second stage implements a radix 2 reconciling with the footed dynamic logic comparator. Constant Delay logic is utilized in the second stage due to its domino compatibility and it acts as a high performance logic boundary between the dynamic comparator and the static logic comparator. The clock tree is arranged such that the CD logic always operates in the high performance D to Q mode. The static inverted comparison circuit acts as a Logic Block for the constant delay comparator which reduces the unwanted glitch that is seen at the output while computing the final stage comparison. Inversion Property is employed in each of the stages in order to avoid unnecessary inverters.

This chance node is thus resolved or collapsed into a single EV, in this case $675,000. Now use this amount as the payoff value for the “submit application” branch of its decision node. You may notice that the “don’t submit application” branch also can have an expected value, in this case (-$100,000). You resolve a decision node in terms of the greatest decision branch EV and disregard any lower values. Use double-hatch marks to indicate a branch from a decision node that is disregarded.
