Olfaction the amygdala and is involved in emotional and autonomic responses to odor. It also projects to the hippocampus and is involved in motivation and memory. Odor information is stored in long-term memory and has strong connections to emotional memory. This is possibly due to the olfactory system's close anatomical ties to the limbic system and hippocampus, areas of the brain that have long been known to be involved in emotion and place memory, respectively. Since any one receptor is responsive to various odorants, and there is a great deal of convergence at the level of the olfactory bulb, it may
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,
