In their paper [1], Tsoi and Tan present what they call a "canonical form", which they claim to be identical to that proposed in Nerrand et al [2]. They also claim that the algorithm which they present can be applied to any recurrent neural network. In the present comment, we disprove both claims. Back in 1993, Nerrand et al. [2] proposed a general approach to the training of recurrent networks...

A new perceptron learning rule which works with multilayer neural networks made of multi-state units is obtained, and the corresponding convergence theorem is proved. The deenition of perceptron of maximal stability is enlarged in order to include these new multi-state perceptrons, and a proof of existence and uniqueness of such optimal solutions is outlined.

Information extraction is initially applied for identification of desired information from natural language documents and conversion of the extracted text into a self-defined presentation. With the rapidly increasing amount of available information sources and electronic documents on the World Wide Web, information extraction is extended for identification from structured and semi-structured we...

Background To study the interaction between idiopathic macular telangiectasis type 2 (MacTel2) and coexistent diabetic retinopathy (DR) during long term follow up. Methods A retrospective chart review was done for all eyes with MacTel2 and DR with a minimum 2 years follow up. Eyes with other retinal disorders and poor quality imaging were excluded. Data collected included demographics, presen...
