Relationship between short- and long-term memory and short- and long-term extinction
Neurobiology of Learning and Memory, 2005Both the acquisition and the extinction of memories leave short- and long-term mnemonic traces. Here, we show that in male Wistar rats, the short-term memory for a step-down inhibitory avoidance task (IA) is resistant to extinction, and that its expression does not influence retrieval or extinction of long-term memory.

Short-term, intermediate-term, and long-term memories
Behavioural Brain Research, 1993This paper focuses on the temporal dimension of memory formation and storage. Is the usual two-fold separation between short-term memory (STM) and long-term memory (LTM) sufficient to encompass all the phenomena of memory? The traditional view is that STM grades into LTM.

Neural Computation, 1997
Learning to store information over extended time intervals by recurrent backpropagation takes a very long time, mostly because of insufficient, decaying error backflow. We briefly review Hochreiter's (1991) analysis of this problem, then address it by introducing a novel, efficient, gradient based method called long short-term memory (LSTM). Truncating

Separate mechanisms for short- and long-term memory
Behavioural Brain Research, 1999It has been assumed for over a century that short-term memory (STM) processes are in charge of cognition while long-term memory (LTM) is being formed, a process that takes hours. A major question is whether STM is merely a step towards LTM, or a separate entity.

A Modified Long Short-Term Memory Cell
International Journal of Neural Systems, 2023Machine Learning (ML), among other things, facilitates Text Classification, the task of assigning classes to textual items. Classification performance in ML has been significantly improved due to recent developments, including the rise of Recurrent Neural Networks (RNNs), Long Short-Term Memory (LSTM), Gated Recurrent Units (GRUs), and Transformer ...

In this chapter, you will learn about recurrent neural networks and long short-term memory models. You will also learn how LSTMs work and how they can be used to detect anomalies and how you can implement anomaly detection using LSTM. You will work through several datasets depicting time series of different types of data such as CPU utilization, taxi ...

Long short-term memory with activation on gradient
Neural Networks, 2023As the number of long short-term memory (LSTM) layers increases, vanishing/exploding gradient problems exacerbate and have a negative impact on the performance of the LSTM. In addition, the ill-conditioned problem occurs in the training process of LSTM and adversely affects its convergence.

A review on the long short-term memory model
Artificial Intelligence Review, 2020Long short-term memory (LSTM) has transformed both machine learning and neurocomputing fields. According to several online sources, this model has improved Google’s speech recognition, greatly improved machine translations on Google Translate, and the answers of Amazon’s Alexa.

Immediate Memory for Faces: Long- or Short-Term Memory?
Quarterly Journal of Experimental Psychology, 1973Immediate recognition memory span and short-term forgetting for non-verbal stimuli (“unfamiliar faces”) were investigated in normal subjects and amnesic patients. Surnames were used as a verbal control. It was found that normal subjects had a reliable immediate recognition span of one for faces and that there was no decrement in performance in the ...

Effect of corticosteroids on short-term and long-term memory
Neurology, 2005The effect of acute high-dose glucocorticoid therapy on memory function in patients with acute optic neuritis (n = 9) and multiple sclerosis (n = 21) was studied. All patients had reversible impairment of long-term memory functions, whereas measures of short-term memory, attentional functions, and alertness remained unaffected.
