Abstract

As the population grows and e economic development, houses could be one of basic needs of every family. Therefore, housing investment has promising value in the future. This research implements the Self-Organized Map (SOM) algorithm to cluster house data for providing several house groups based on the various features. K-means is used as the baseline of the proposed approach. SOM has higher silhouette coefficient (0.4367) compared to its comparison (0.236). Thus, this method outperforms k-means in terms of visualizing high-dimensional data cluster. It is also better in the cluster formation and regulating the data distribution.

Abstract

In education, essay is considered as the best tool to evaluate student’s high order thinking and understanding. In the other hand, manual processing and grading essay answers by a teacher need much time and tending to subjectivity grading. Meanwhile automatic essay grading in e-learning system find the difficulties in comparing model or key answer to student’s answer because student’s can answer the question with so various way. That means a right answer also can be so various, for they have same semantic meaning. This paper proposed automatic essay grading using Latent Semantic Analysis. But before the texts being scored, they will be pre-processed using stop words removal and synonyms checking. Calibration process implemented for dealing with the various possible right answer and help to simplify the term matrix. Implementation of this approach using Java Programming Language and WordNet as lexical database for searching the synonyms of every given words. The accuracy obtained by this method is 54.9289%.

Abstract

Dalam ilmu Biologi, terdapat berbagai cara untuk menentukan kedekatan antar dua individu, antara lain dengan mengamati kesamaan morfologi fisik kemudian membuat dendogram dan pembuatan pohon filogeni untuk menelusur kekerabatan berdasarkan sejarah evolusi suatu makhluk hidup. Akan tetapi pendekatan ini sangat sulit untuk dilakukan apabila hewan yang akan ditentukan kekerabatannya tidak berada dalam kondisi yang hidup, sehingga sangat sulit untuk mengamati ciri-ciri fisik yang ada. Penelitian ini bertujuan untuk memberikan pendekatan yang berbeda dalam menentukan kekerabatan hewan dengan menggunakan struktur protein IGF2. Kekerabatan dilakukan dengan menggunakan metode clustering K-Means. Untuk memudahkan dalam melakukan pengelompokkan struktur protein yang memiliki panjang sekuens yang beragam, maka teknik n-gram digunakan untuk memecah string menjadi beberapa subsekuens dengan panjang yang sama. Pengelompokkan dengan metode K-Means telah dilakukan dan mendapatkan hasil terbaik pada jumlah cluster sebanyak tujuh cluster, dengan silhouette coeficient rata-rata sebesar 0.331, indeks puritysebesar 0.735, dan precisionsebesar 0.823 yang mengindikasikan proses clustering cukup efektif.In Biology, there were various ways to determine the closeness between two individuals, such as by observing the similarity of physical morphologies then making a dendogram and also by making a phylogenetic tree to trace the kinship based on the evolutionary history. However, this approach is very difficult to do if the animal whose relatives are to be determined is not in a living condition, so it is very difficult to observe the existing physical characteristics. This study aims to provide a different approach in determining animal kinship using clustering algorithm to cluster the IGF2 protein structures. Kinship is determined using the K-Means clustering method. N-gram technique is used to break the sequence into several subsequences with the same length, because each sequence can have various length. Grouping with the K-Means method had been done and got the best results on the number of clusters as many as seven clusters, with an average silhouette coefficient of 0.331, a purityindex of 0.735, and a precisionof 0.823 which indicates the clustering process is quite effective.
