March. 2008 - Using a Naïve Bayes Classifier based on K-Nearest Neighbors for Static Hand-Gesture Recognition
We present an effective and fast method for static hand gesture recognition. This method is based on classifying the different gestures according to geometric-based invariants which are obtained from image data after segmentation; Full Text

Nov 2004 - A Novel Fuzzy Approach to Speech Recognition
This paper presents a novel approach to speech recognition using fuzzy modeling. The task begins with conversion of speech spectrogram into a linguistic description based on arbitrary colors and lengths. While phonemes are also described using these fuzzy measures, and recognition is done by normal fuzzy reasoning, a genetic algorithm optimizes phoneme definitions so that to classify samples into correct phonemes. The method is tested over a standard speech data base and the results are presented. Full Text Slides

Nov 2004 - Zamin, an agent based artificial life model
Zamin artificial life model is designed to be a general purpose environment for researches on evolution of learning methods, living strategies and complex behaviors and is used in several studies thus far. As a main target for Zamin's design has been its expandability and ease of problem definition, a new agent based structure for this artificial world is introduced in this paper, which is believed to be much easier to use and extend.

Dec. 2008 - Implementing and Evaluating Hand Gesture Recognition for Human-Robot Joint-Action
In this thesis, a reliable, fast and robust approach to static hand gesture recognition in the domain of a Human-Robot interaction system is presented. The algorithm has been successfully operated in the gesture recognition module of the Joint-Action Science and Technology (JAST) project.

Aug. 2004 - Constructing a Fuzzy Controller a biped-robot with Active Learning Method (ALM) (in persian)
This thesis presents an approach to build up a fuzzy controller with active learning method (ALM). The controller settings are extracted automatically from the existing data of a biped robot. Full Text
