Hippocampus anatomy These limbic structures include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean once suggested, as part of his triune brain theory, that the limbic structures constitute the neural basis of emotion. While most neuroscientists no longer believe in the concept of a unified "limbic system", these regions are highly interconnected and do interact with one another. Starting at the dentate gyrus and working inward along the S-curve of the hippocampus means traversing a series of narrow zones. The first of these, the dentate gyrus (DG), is actually a separate structure, a tightly packed layer of small granule cells
Long short-term memory network that performs better than the widely used long short-term memory neural network. Further in 2017 Microsoft reported reaching 95.1% recognition accuracy on the Switchboard corpus, incorporating a vocabulary of 165,000 words. The approach used "dialog session-based long-short-term memory". There are several architectures of LSTM units. A common architecture is composed of a memory "cell", an "input gate", an "output gate" and a "forget gate". An LSTM "cell" takes an input and stores it for some period of time. This is equivalent to applying the identity function (formula_1 to the input. Because the derivative of the identity function is constant,
