Today, in our class of Perceptual Computing, Professor Shin Su-young in the field of bioinformation of ASAN Medical Center lectured. The topic was "Introduction to Artificial Neural Networks". Artificial Neural Networks or ANN, for example, is a technology utilized as a technology of tagging the face in the facebook. Professor gave us explanations about "Parallel Distributed Prossesing and Connectionist Computation, the directions of recent researches introducing Biologically Inspired Computational Models first. Connectionist Computation is mainly used term in cognitive science, and Parallel Distributed Prossesing is the term approached in the way of computer learning.
There were a lot of attempts to research how people think and research and apply it to the computer. For this, research regarding Neurons in the Brain was progressed. Modeling the relationship between each neurons and conveyance of stimulus and trying to apply it to computer technology is summarized as Perceptrons. This is the root of Artificial Neural Networks. Directions of recent researches are conducted towards Multi Layer Perceptrons(MLP) complementing the drawbacks of XOR.
Method utilizing the information acquisition through learning is being researched as well, and for this, we use Mathematical Optimisation Technology. This immediately led to Neural Network Mathematics. For the method of training MLP, we utilize BackPropagation Algorithm. Among the recent projects of Google, there is Google Brain Simulator Identifies Cats on Youtube, and this is the project that researches the technology to sort the cats after leaning all the videos on the Utube, and is presented as a successful example of theory explained above in his lecture.
We sincerely thank you for Profession Shin Su-young who explained well in an easy way through various examples of difficult theories, it has been time of great help for the students who are taking class in Perceptual Computing.
