The loss function here is mean squared error of the predicted Q-value and the target Q-value – Q*. 8. This field of research has been able to solve a wide range of complex decision-making tasks that were previously out of reach for a machine. Deep reinforcement learning combines artificial neural networks with a reinforcement learning architecture that enables software-defined agents to learn the best actions possible in virtual environment in order to attain their goals. These results indicate the great potential of multiagent reinforcement learning for artificial intelligence research. Check out the below maze to better understand the intuition behind how this works: Now, there are 2 scenarios with 2 different starting points and the agent traverses different paths to reach the same penultimate state. The comparison between Q-learning & deep Q-learning is wonderfully illustrated below: So, what are the steps involved in reinforcement learning using deep Q-learning networks (DQNs)? Instead of pixel information, there are four kinds of information given by the state (such as the angle of the pole and position of the cart). However, the real world contains multiple agents, each learning and acting independently to cooperate and compete with other agents. Yet, deep reinforcement learning requires caution and understanding of its inner mechanisms in order, In reinforcement learning (RL), stochastic environments can make learning a policy difficult due to high degrees of variance. 6. This is the strategy or policy. Q(s’,a) again depends on Q(s”,a) which will then have a coefficient of gamma squared. So, we try to learn to map for a constantly changing input and output. Particular challenges in the online setting. So when I read about the incredible algorithms DeepMind was coming up with (like AlphaGo and AlphaStar), I was hooked. This would essentially be like a cheat sheet for the agent! Start with the basics of reinforcement learning and explore deep learning concepts such as deep Q-learning, deep recurrent Q-networks, and policy-based methods with this practical guide Key Features. This manuscript provides an introduction to deep reinforcement learning models, algorithms and techniques. There are certain concepts you should be aware of before wading into the depths of deep reinforcement learning.

Title:An Introduction to Deep Reinforcement Learning.Abstract: Deep reinforcement learning is the combination of reinforcement learning (RL) and deep learning.This field of research has been able to solve a wide range of complex decision-making tasks that were previously out of reach for a machine. Deep reinforcement learning (DRL) is the combination of reinforcement learning (RL) and deep learning. Here, we propose to learn a separate reward estimator to train the value function, to help reduce variance caused by a noisy reward. In this setting, we focus on the tradeoff between asymptotic bias (suboptimality with unlimited data) and overﬁtting (additional suboptimality due to limited data), and theoretically show that while potentially increasing the asymptotic bias, a smaller state representation decreases the risk of overﬁtting.

India, a nation of 1.2 billion people, is the most varied market in terms of food in the world, cheers to regional differences in cultures, lifestyles and preferences. Today’s consumers select those restaurants or brands that understand them and provide them with the experience they seek. India is a price sensitive country and good bargains and promotions catch consumers’ attention. This trend is seen across consumers categories. For Indians getting valued brands for a lesser price enhances their dining experience and is a motivating factor for them to be more loyal to the restaurants or brands. With the changing habits, there is an increased preference for convenience and eating out. According to various industry experts, nuclear families and bachelors are turning towards takeout, home delivery and semi-prepared meals (ready-to-eat/ ready-to-cook meals) as these are lower cost and also time saving options. According to a recent report by Financial Express Online, this is one important reason why FMCG companies like Nestle, Parle, or PepsiCo have not changed the prices of their products like Maggi, Lay’s and Parle-G for nearly a decade now. Harish Bijoor, Founder Harish Bijoor Consultancy Inc, told Financial Express Online, “These price points become memory points as well. The consumer reaches out to these packs and to an extent has an economy story in his or her mind for sure. The moment this price point is altered, even by 50 paise, there is a jarring effect in the minds of the consumer, retailer, and indeed the entire trade channel.” The Internet economy is bringing convenience in our lives that consumers want everything at the touch of a button, which led to the emergence of food-delivery platforms in India. The online food ordering business in India has boomed in last two years with the entry of several platforms such as UberEats, Zomato, Swiggy, among others. Considering the potential in the Indian market, these platforms have been expanding foothold in India and have more than three lakh restaurants listed on them. These platforms have gained increased usage by consumers by focusing on single-serve value-meals and varied cuisines. According to RedSeer’s Foodtech Market Updates, the foodtech industry has seen an overall Gross Merchandise Value growth of close to 140 per cent in 2018, with order volumes increasing by a whopping 176 per cent on account of discounts and value deals provided by food aggregators. Keeping up with this trend in the country, a global QSR brand like Subway has introduced Chhota Sub, a 4-inch-mini submarine sandwich in four flavours for consumers who are constantly seeking value-deal options with exciting taste. Subway India in past had introduced SubWraps as a snacking product priced at Rs 49 for vegetarian options and Rs 69 for non-vegetarian options. The brand is also running ‘Sub of the Day Offer’ for its guests to have an opportunity to relish their favourite submarine sandwich at an attractive price once a week and is a popular value deal. With the rapid growth of millennials as the major consumer segment, the perception of product’s value and premiumisation has also altered. Consumers no longer consider a product premium based on just a high price tag. Globally, less than one-third (31 percent) of the consumers consider a product premium only because it is expensive. Thus, a clear demand for value-for-money is emerging amongst the younger consumers.
