Using Feature Weights to Improve Performance of Neural Networks

Different features have different relevance to a particular learning problem. Some features are less relevant; while some very important. Instead of selecting the most relevant features using feature selection, an algorithm can be given this knowledge of feature importance based on expert opinion or prior learning. Learning can be faster and more accurate if learners take feature importance into account. Correlation aided Neural Networks (CANN) is presented which is such an algorithm. CANN treats feature importance as the correlation coefficient between the target attribute and the features. CANN modifies normal feed-forward Neural Network to fit both correlation values and training data. Empirical evaluation shows that CANN is faster and more accurate than applying the two step approach of feature selection and then using normal learning algorithms

A Generalized Method for Integrating Rule-based Knowledge into Inductive Methods Through Virtual Sample Creation

Hybrid learning methods use theoretical knowledge of a domain and a set of classified examples to develop a method for classification. Methods that use domain knowledge have been shown to perform better than inductive learners. However, there is no general method to include domain knowledge into all inductive learning algorithms as all hybrid methods are highly specialized for a particular algorithm. We present an algorithm that will take domain knowledge in the form of propositional rules, generate artificial examples from the rules and also remove instances likely to be flawed. This enriched dataset then can be used by any learning algorithm. Experimental results of different scenarios are shown that demonstrate this method to be more effective than simple inductive learning

Empirical learning aided by weak domain knowledge in the form of feature importance

Standard hybrid learners that use domain knowledge require stronger knowledge that is hard and expensive to acquire. However, weaker domain knowledge can benefit from prior knowledge while being cost effective. Weak knowledge in the form of feature relative importance (FRI) is presented and explained. Feature relative importance is a real valued approximation of a feature’s importance provided by experts. Advantage of using this knowledge is demonstrated by IANN, a modified multilayer neural network algorithm. IANN is a very simple modification of standard neural network algorithm but attains significant performance gains. Experimental results in the field of molecular biology show higher performance over other empirical learning algorithms including standard backpropagation and support vector machines. IANN performance is even comparable to a theory refinement system KBANN that uses stronger domain knowledge. This shows Feature relative importance can improve performance of existing empirical learning algorithms significantly with minimal effort

Politik Hukum Adat Bima: Dari Sintesis, Transpalntasi Hingga Konservasi Hukum

Tujuan peneltian ini adalah untuk mengetahui pola perkembangan hukum adat Bima dan melihat bagaiman politik hukum adat Bima serta eksistensinya pasca reformasi, sehingga diketahui kecenderungannya. Jenis penelitian adalah non-doctrinal atau socio legal (kualitatif), dengan pendekatan sejarah dan yuridis (historical and juridical approach), Data yang digunakan terdiri atas, data primer dan data sekunder. Hasil dari penelitian menemukan; (1) pola perkembangan hukum adat Bima terdapat, a) sitensis hukum, yaitu ketika hukum adat dan hukum Islam bertemu lalu saling mengisi, dan tidak terdapat konfrontasi diantara keduanya, b) transplantasi hukum, terjadi ketika sistem hukum kolonial merangsek ke dalam tatanan lokal dengan membatasi kewenangan lembaga peradilan Islam, yang menyebabkan kekosongan hukum, c) Integrasi hukum, ketika pemerintah pusat membangun politik hukum keseragaman lewat kodivikasi dan univikasi, (2) ketika reformasi berhembus, hukum adat Bima terpositivisasi, lewat berbegai bentuk kebijakan, seperti perda, (3) adalah komunitas masyarakat Donggo yang yang sampai saat ini masih menjalankan hukum adat, dengan segala kelentunturan dan berbagai bentuk sanksinya, mulai dari di nasehati, di nikahkan secara paksa, di pukul, di ‘baja’ (di arak keliling kampung), sampai pada pemberian sanksi ganda. Bertahannya hukum adat di Donggo akibat langsung dari upaya konservasi oleh berbagai pihak, poin dua dan tiga selain menjadi pola perkerkembangan hukum adat Bima (positivisasi dan konservasi) juga menjadi kecenderunganya pasca reformasi

PERAN AKADEMISI DALAM PEMBERIAN BANTUAN HUKUM BAGI MASYARAKAT KURANG MAMPU DI INDONESIA

Every citizen of Indonesia, of course longing for a fast, simple and low cost judicial process. This may be done everyone has an access to justice without any exception. These conditions have been realized by the Constitutional Court decision that had to cancel Article 31 of Law Number 18 Year 2003 on Advocates, because the article is considered contrary to the Constitution of 1945 and has no binding legal force. However, the implementation of the Constitutional Court ruling will not necessarily be implemented, because in practice there are still debates among law enforcer (police, prosecutors, judges, lawyers) even academics about the legal standing of the law lecturer who perform service in the form of assistance to disadvantaged communities who are dealing with legal issues. This condition is caused by a lack of positive response to the Constitutional Court, and the lack of response is due to the lack of legal resources by extracting the part of law enforcement and academics for a growing source of law.

THE EFFECT OF KCN ON GOLD ADSORPTION FROM HCl SOLUTION BY SYNTHESIZED MAGNETIC ACTIVATED CARBON COMPOSITE FROM IRON SAND

The composites of magnetic activated carbon has been successfully synthesized by utilizing the available materi- als abundant in the country such as iron sand, and other chemicals which are easily procured in local markets at low prices. The phase identifi cation using X-ray diffraction technique showed that the magnetic part is Fe3O4 with crystallite size about 30 nm. The effectiveness of gold absorption from chloride solution by activated carbon magnetic composites are close to 100% and showed very dependent on pH. An addition of KCN in to the gold chloride solution can reduce effectiveness of activated carbon to adsorb gold by up to 20%. These might be caused by the formation of Au(CN)2-, in the solution, which could change the mechanism of adsorption of gold by the activated carbon. Based on these experimental results, by using chloride it is possible to recover valuable minerals from the ore processing of mining, which are economically,as well as environment friendly and safe
