Hippocampus Hippocampus The hippocampus (named after its resemblance to the seahorse, from the Greek ἱππόκαμπος, "seahorse" from ἵππος "hippos", "horse" and κάμπος "kampos", "sea monster") is a major component of the brains of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located under the cerebral cortex (allocortical) and in primates in the medial temporal lobe. It contains two main
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,
