episodic reinforcement learning with associative memory 

Exp. There is also recurrent excitation weighted by γ and recurrent inhibition weighted by δ. A lower price may be preferred, or alternatively, a higher price may be preferred based on perceived higher quality, although in reality such a correlation is weak (Faulds and Lonial, 2001). The model explains how attention, memory and decision making interact through the use of spatial indices that bind the different processes together. 20, 723–767. Neural Inf. The role of locus coeruleus in the regulation of cognitive performance. Interaction of norepinephrine with cerebrocortical activity evoked by stimulation of somatosensory afferent pathways in the rat. Note that the choice distribution as well as the response time distribution changes. Figure 2: A modification of the original model to take account of the evidence of links between working memory and long-term memory (LTM). 1, 161–176. In the simulations reported below, the si are set to 0 or 1 to indicate the presence of an object at the corresponding location, but could in principle code for the visual salience of each object. The field also has yet to see a prevalent consistent and rigorous approach for evaluating agent performance on holdout data. Note that we use the word “feature” for the individual elements of the perceptual feature vectors rather than as synonyms for attributes or properties. Such bottom up salience can interact with top down stimulus bias from the accumulator component to select which objects to consider. This is the idea that is also used in modern reinforcement learning (Sutton and Barto, 2018). Here we test the role for episodic memory-specifically item versus associative memory-in supporting value-based choice. This contrasts with standard reinforcement learning that is not forward looking in this way. DeAngelis, D. L., Post, W. M., and Travis, C. C. (2012). Affect. This is entirely a system property of the model as there is no explicitly set discount factor. We do, however, not explore this feature of the memory system further. A recurrent connectionist network uses two types of connections to implement semantic and episodic memory. Once the effect of synaptic depression kicks in, the attractor will collapse and transition to a semantically related state and another attractor. Learning and memory of this association can be measured at various time points after training by testing flies by placing them at the choice point between odors A and B, and allowing them to choose between these odors. Rev. This means that we may also decide that it does not matter which particular choice is made. Figure 9A shows the decision between two stimuli where one has an immediate value and the other is only indirectly associated with a value through a number of episodic associations, ranging from none to … Frank, M. J., Loughry, B., and O'Reilly, R. C. (2001). Deictic codes for the embodiment of cognition. Now let us consider choosing between pasta types that are not only differently shaped, but also from different brands. 41, 67–85. 6, 114–133. It can also be used to activate associations that in turn may have positive or negative valuations. To improve sample efficiency of reinforcement learning, we propose a novel framework, called Episodic Reinforcement Learning with Associative Memory (ERLAM), which associates related experience trajectories to enable reasoning effective strategies. Figure 3: The model following the introduction of a fourth component, the episodic buffer, a system for integrating information from a range of sources into a multidimensional code (Baddeley 2000). Decis. Diffusion decision model: current issues and history. (2000). doi: 10.1023/A:1022676722315, Wickelgren, W. A. Vicarious trial and error. This suggests that the amount of feed-forward inhibition can be used to control a trade-off between accuracy and speed in decision making (Wickelgren, 1977). In this … Christina Maslach, Wilmar B. Schaufeli, Michael P. LeiterVol. This model was the result of a study called Episodic Curiosity through Reachability, the findings of which Google AI shared yesterday. In particular, the longer the reaction time, the wider the distribution for the less preferred alternative becomes. Cogn. Lerner, I., Bentin, S., and Shriki, O. Technical Report, Stanford Univ Ca Stanford Electronics Labs. It is this future state that is evaluated, rather than the direct properties of the item. Psychol. Rescorla, R. A., and Wagner, A. R. (1972). Choosing between two objects with one attribute each. Time machines aren't easy to build; they also aren't easy to use. Rescorla-Wagner Model. CB, TT, BJ, AW, and PG planned the paper, the theoretical framework, and wrote the paper. Mayer, H. L. Roitblat, S. W. Wilson, and B. Blumberg (Cambridge, MA: MIT Press), 348–353. The explanation for this effect is that increased feed-forward inhibition slows down the accumulation of value and allows the effect of noise to decrease because it is integrated over a longer time. 67, 11–34. doi: 10.1016/j.tics.2016.01.007, Redish, A. D. (2016). Sam knows from experiences of other small towns that it is probable that there is a hotel close to the church, a form of episodic memory. Research on such episodic learning has revealed its unmistakeable traces in human behavior, developed theory to articulate algorithms It allows the accumulation of information about current state of the environment in a task-agnostic way. For example, colorful cardboard boxes may associate to a fancy Italian restaurant, and so to better quality pasta than a simple plastic packaging. Acad. Here we present an extended model that can be used as a model for decision making that depends on accumulating evidence over time, whether that information comes from the sequential attention to different sensory properties or from internal simulation of the consequences of making a particular choice. How visual attention and choice are affected by consumer preferences and properties of the supermarket shelf. The constant n is here set to 2. The square arrowhead represents a facilitating input, in this case the selection of a particular accumulator. Mechanisms for context processing could also be included to make the associative process more efficient and goal directed. Neural networks and physical systems with emergent collective computational abilities. Understanding the decision making process and its relationship to visual inputs can be very valuable to identify problems in learned behavior. Pupil diameter tracks changes in control state predicted by the adaptive gain theory of locus coeruleus function. One prominent view holds that episodic memory emerged recently in humans and lacks a “(neo)Darwinian evolution” [Tulving E (2002) Annu Rev Psychol 53:1–25]. When the integration process reaches a particular criterion, the winning alternative in a decision layer is chosen (Figure 4). λ is a decay constant and N(σ) is a normally distributed noise term. For example, previous work has implicated both working memory and procedural memory (i.e., reinforcement learning) in guiding choice. In the minimal case, attention is randomly directed to the different objects, but the model also allows for attention to be based on perceptual salience through the bidirectional connections with the spatial attention component. Figure 9A shows the decision between two stimuli where one has an immediate value and the other is only indirectly associated with a value through a number of episodic associations, ranging from none to nine steps. This may be sufficient to explain routine decisions but in general, we often collect evidence for different alternatives over time and take action only when sufficient evidence has been accumulated (Ratcliff et al., 2016). (1980). By assuming that spatial attention is responsible for selecting the appropriate accumulator, the same model will work for an arbitrary number of objects and it gives spatial attention a central role in decision making. That is, it should make a discernible positive difference. The first is the perceptual system that produces a sequence of “feature descriptors” from an attended object. Leth-Steensen, C., Elbaz, Z. K., and Douglas, V. I. R. Soc. Irrational time allocation in decision-making. Rev. Positive feedback tends to force dynamic systems into quickly settling into new states (DeAngelis et al., 2012) and minimize the transition period, as can be seen in Figure 5E for response time. Reinforcement learning systems usually assume that a value function is defined over all states (or state-action pairs) that can immediately give the value of a particular state or action. An increased noise level also reduces the reaction time. (1982). To improve sample efficiency of reinforcement learning, we propose a novel framework, called Episodic Reinforcement Learning with Associative Memory (ERLAM), which associates related experience trajectories to enable reasoning effective strategies. doi: 10.1371/journal.pone.0183710, Amari, S.-I. Episodic memory does not reproduce, it constructs, and the reconstruction of previous episodes is based on information from many sources with the assistance of many neural systems (Rubin, 2006). Latching dynamics in neural networks with synaptic depression. Episodic memory helps to solve a significant number of tasks in the real world. We have presented a new system-level model of decision making that combines components for attention, perception, semantic, and episodic memory with an accumulator stage that adds up value over time until a choice can be made. Instead, discounting is a consequence of how the memory, value and accumulator components interact. Object-Oriented Dynamics Learning through Multi-Level Abstraction. PLoS ONE 12:e0183710. We show that when equipped with an episodic memory system inspired by theories of reinstatement and gating, the meta-learner learns to use the episodic and model-based learning … Twin and ...Read More, There are many differences between men and women. Here, we describe how this memory mechanism can support decision making when the alternatives cannot be evaluated based on immediate sensory information alone. These values are used by a selection mechanism to decide which action to take. Instead we first imagine, and then evaluate a possible future that will result from choosing one of the alternatives. An object Oi is modeled as a set of attributes {aij} where each attribute is associated with a binary feature vector of size n, aij = 〈 fij1 … fijn〉. The model has a number of attractive properties: When perceptual states are directly associated with value through the memory component, the model reduces to the value function of a reinforcement learning system (Sutton and Barto, 2018), or critic of an actor-critic architecture (Joel et al., 2002). Tolman, E. C., and Honzik, C. H. (1930). Cogn. Sompolinsky, H., and Kanter, I. This article is about how memories from earlier events may influence choice tasks. Visualizing Episodic Memory with Hopfield Network. U.S.A. 104, 1726–1731. This includes adaptive gain control for memory retrieval (Mather and Sutherland, 2011) and value accumulation (Aston-Jones and Cohen, 2005). There are a number of venues for future research. (2000). A, Negative correlation between memory and reinforcement learning model fit (log likelihood) across participants. Since there is only one attribute, the value of the object is given by that single attribute. The activity of the accumulators can be made to influence the selection in the attention component. In this chapter we See Supplementary Material for additional parameters. It would also be interesting to further analyze the properties of the implicit discounting that occurs as a result of the episodic associations. We base the memory component on an earlier memory model (Balkenius et al., 2018). doi: 10.1126/science.283.5401.549, Usher, M., and McClelland, J. L. (2001). Figure 1: Passive-dissipation model showing how delay can improve performance on inhibitory tasks (from Simpson et al. System level models of the brain aim at explaining which different components are needed for a particular cognitive function. ∙ University of Oxford ∙ 0 ∙ share Learning with less supervision is a major challenge in artificial intelligence. Rev. However, since value is used here in a sequential accumulation process (described below), it is not necessary that the value component supports higher order conditioning, which is otherwise the basis for chaining in reinforcement learning. Another property of the model is that is explains how different kinds of memory structures can be used to support decision making and how different kinds of associations with different time constants can all contribute to a decision. Using the framework of Marr's … Affect. Figure 3: Comparison of the mixed conditions of the Dots (now called Hearts and Flowers) and Simon tasks in percentage of correct responses (based on Davidson et al. AMiner aims to provide comprehensive search and mining services for researcher social networks. Another alternative would be selecting a product solely based on price. “Automatic and controlled processes in semantic priming: an attractor neural network model with latching dynamics,” in Proceedings of the Cognitive Science Society, Vol. Tsetsos, K., Usher, M., and Chater, N. (2010). These are finally accumulated in the fourth component until a decision criterion is met and the system produces a choice as output. Acta Psychol. It also uses cookies for the purposes of performance measurement. To improve sample efficiency of reinforcement learning, we propose a novel framework, called Episodic Reinforcement Learning with Associative Memory (ERLAM), which associates related experience trajectories to enable reasoning effective strategies. The gray arrows represent interactions that we do not address in this paper. Here values are assumed to sum up to one. We tested the model's ability to sum contributions from individual attributes, and as expected the model selected each of the alternatives with probability 0.5 (Figure 7). Learn. See text for further explanation. 67, 165–174. Unlike a planning process, there is not necessarily any systematic evaluation of different possible future action sequences. When both values are available immediately, the model will mostly select stimulus B, but as the number of memory transitions needed increases, the model will become more likely to select the immediate lower reward. 108:550. doi: 10.1037/0033-295X.108.3.550, Usher, M., and McClelland, J. L. (2004). The details of these semantic memory transitions were described in an earlier paper (Balkenius et al., 2018). … ∙ 0 ∙ share Episodic memory plays an important role in the behavior of animals and humans. To the right, there is a spruce plantation and that is normally too dark for chanterelles. It will be interesting to see if there is a consistent set of parameters that can reproduce the empirical results. where Ii is the value from the value component when i is the accumulator selected by the input from the spatial attention system, and 0 otherwise. The excitatory value input is weighed by α before it reaches the accumulator. A seemingly distinct challenge is that, cognitively, theories of RL have largely involved procedural and semantic memory, the way in which knowledge about action values or world models extracted gradually from many experiences can drive choice. Figure 4: My current view of the complex and multiple links between working memory (WM) and long-term memory (LTM). We store the best historical values for Proc. Sam knows nothing about mushrooms, but she has heard that there are chanterelles in a nearby forest so she offers to take Pat there. Like other models of choice, the model can handle a situation where there are two objects with one attribute each. Dynamics of pattern formation in lateral-inhibition type neural fields. Robot. This is an episodic memory association that may conjure up scenes from your childhood where each part of the scene has its own associations that contribute to the decision. Figure 4: Executive functions and related terms. This is sometimes called latching dynamics (Lerner et al., 2010; Aguilar et al., 2017) and is the mechanism of free association. In psychology, associative memory is defined as the ability to learn and remember the relationship between unrelated items. 05/07/2019 ∙ by Artyom Y. Sorokin, et al. Such a forward looking use of the episodic memory is similar to the forward sweeps found in animal brains as they consider different alternatives (Redish, 2016). In the future, we want to analyze the model from a learning perspective to see how it compares on reinforcement learning tasks. Preference reversal in multiattribute choice. “Residual algorithms: reinforcement learning with function approximation,” in Machine Learning Proceedings, 1995 Proceedings of the Twelfth International Conference on Machine Learning (Tahoe City, CA; Burlington, MA: Morgan Kaufman), 30–37. The decision layer detects when one of the accumulators has reached the decision threshold and activates the corresponding output. The model does not sample the value of the product directly. Amsterdam: Elsevier. Speed-accuracy tradeoff and information processing dynamics. Once the threshold is reached, the decision layer will reset the accumulators. The purpose of the simulations is to illustrate the properties of the system model in different situations rather than to find optimal parameters to reproduce any particular empirical study. One can find extensive evidence from both psychology and neuroscience for the type of mechanisms we propose. Simon, H. A. Continual Learning with Tiny Episodic Memories. 39. doi: 10.1017/S0140525X15000667, Mather, M., and Sutherland, M. R. (2011). Even the location of the item on the shelf, how hard it is to reach, or whether the shelf is full or not, may influence the decision. The memory should be able to replace the classical "episodic buffer" commonly used in reinforcement settings. However, one challenge in the study of RL is computational: The simplicity of these tasks ignores important aspects of reinforcement learning in the real world: (a) State spaces are high-dimensional, continuous, and partially observable; this implies that (b) data are relatively sparse and, indeed, precisely the same situation may never be encountered twice; furthermore, (c) rewards depend on the long-term consequences of actions in ways that violate the classical assumptions that make RL tractable. 68, 455–463. A neural model of the dynamic activation of memory. (C) The probability of selecting each object depends on how different the values V(A) and V(B) are for the two objects. The Google Brain team with DeepMind and ETH Zurich have introduced an episodic memory-based curiosity model which allows Reinforcement Learning (RL) agents to explore environments in an intelligent way. The system-level computational model demonstrates how perception, attention, memory, and choice mechanisms can interact in decision-making processes. The number of transitions needed to reach a valued memory state depends on how the episodic associations are set up in memory (B) Because of the discounting of future value, the model can relate a smaller immediate reward, 0.9 for B, to a future larger reward, 1 for A. Proc. Psychol. The Supplementary Material for this article can be found online at: https://www.frontiersin.org/articles/10.3389/fpsyg.2020.560080/full#supplementary-material, Abbott, L. F., Varela, J., Sen, K., and Nelson, S. (1997). Behav. An approach to episodic associative memory is presented, which has several desirable properties as a human memory model. We have previously developed a model of memory processing that includes semantic, episodic and working memory in a comprehensive architecture. Neural Netw. J. Actor-critic models of the basal ganglia: new anatomical and computational perspectives. doi: 10.1016/j.appet.2017.04.020, Gilzenrat, M. S., Nieuwenhuis, S., Jepma, M., and Cohen, J. D. (2010). Rev. Considering the case with a single delay τji for each recurrent connection, the state x of the memory network is governed by the following equation, where I is the input, w are the weights of the connections, dji is the synaptic depression and f is the activation function of the nodes. For the particular values used in the simulation, the break-off point where the two stimuli are equally valued occurs at two episodic transitions for the higher valued stimulus. When the gain of this feedback is increased, choices are faster and the system will look more at the alternative that will finally be chosen (Figure 10). Natl. Figure 3. Figure 5 shows some basic properties of the model. However, little progress has been made in understanding when specific memory systems help more than others and how well they generalize. We review the computational theory underlying this proposal and the empirical evidence to support it. Lett. Reinforcement Learning and Episodic Memory in Humans and Animals: An Integrative Framework Annu Rev Psychol. Consumer Behavior chapter 03 Learning and Memory theories Moghimi 1. Cybern. There is a negligible effect on the choice probabilities. This leads to the prediction that an alternative that contains less details and thus produces less transitions should be favored over an alternative that produces many transitions given that the values are the same. As the perceptual system attends to a particular object, different feature vectors are produced over time as different attributes of the objects are processed. Acta Psychol. In psychology, associative memory is defined as the ability to learn and remember the relationship between unrelated items. Res. There are two main components in a standard reinforcement learning system (Sutton and Barto, 2018). Figures 5D–F can be together considered as showing different phasic aspects of the selection mechanism. Keywords: reinforcement learning; associative memory; episodic-like memory; food caching behaviour Introduction Birds of the crow family ( corvidae ) have been proposed as animal models for human cognitive neuroscience, because of their remarkably complex cognition (Clayton & Emery, 2015). 2008; : 889-896. In parallel, a nascent understanding of a third reinforcement learning system is emerging: a non-parametric system that stores memory traces of individual experi-ences rather than aggregate statistics.
