Key Research Activities
His current research activities are now concentrated on the application and extension of the Turbo technology in various domains, including his research on Artificial thinking, because the Turbo-decoding has been recognized as a new instance of the very general principle of Belief propagation; one application of this principle has been invented for the decoding of Low-density parity-check codes (LDPC codes also known as Gallager codes, in honor of Robert G. Gallager, who developed the LDPC concept in his doctoral dissertation at MIT in 1960 as a theoretical model whose practical implementation was not widely developed until recently). The Turbo principle is generalized now by Claude Berrou and his lab team for the processing of various functions such as the demodulation, the detection or the equalization using a network of multiple convolution codes working in parallel with probabilistic feedback.
Other subjects of interest include all their possible applications in the field of artificial intelligence, for example with a better understanding of natural biological thinking and memory for the implementation of such model using neural networks for the processing of pulsed signals with software and hardware methods with auto-selected and self-maintained combinations of activation cycles of adjacent neurons.

“Sunshine of late afternoon—
On the glass tray
a glass pitcher, the tumbler
turned down, by which
a key is lying—And the
immaculate white bed”
—William Carlos Williams (1883–1963)
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?””
—Sigmund Freud (1856–1939)
“Both at-home and working mothers can overmeet their mothering responsibilities. In order to justify their jobs, working mothers can overnurture, overconnect with, and overschedule their children into activities and classes. Similarly, some at-home mothers,... can make at- home mothering into a bigger deal than it is, over stimulating, overeducating, and overwhelming their children with purposeful attention.”
—Jean Marzollo (20th century)
