Just like upgrading the bed you sleep on, few things will improve your life like a good chair. If you park your body in front of a desk all day, it's a good idea to give the humble chair more attention. Some of our favorites are on sale right now. See our Best Office Chairs guide for more. Our top office chair pick is a bit cheaper right now. We've tested more than 35 office chairs in the past year and this is the one to get based on comfort, quality, adjustability, and price. At this price, you'd be hard-pressed to find a cheaper way to get seven points of adjustment. The only thing we don't like is that pet hair tends to cling, so keep a lint roller handy. The Zeph looks wonderful--there are dozens of color customizations--but the only adjustment you can make is to raise the seat up or down. You might think that would make for an uncomfortable chair, but it doesn't. This lack of adjustability is by design as the Zeph is designed to mold to your body. We do suggest you get the seat pad and arms, which add a smidge more comfort, though it does jack the price up a bit. The Zeph is compact, making it a great option for smaller spaces. The humble Hyken is our favorite budget office chair. It reclines, has a breathable mesh fabric on the back and seat, and it's sturdy.

Amazon is having an internal crisis over Alexa right now--its voice assistant is on pace to lose $10 billion this year--so it might not be the best idea to invest in the company's lineup of Alexa-powered devices right now.

Everything is heavily discounted right now for Cyber Monday, so now's one of the best times to buy. We test products year-round and handpicked these deals.

This work provides a Deep Reinforcement Learning approach to solving a periodic review inventory control system with stochastic vendor lead times, lost sales, correlated demand, and price matching. While this dynamic program has historically been considered intractable, our results show that several policy learning approaches are competitive with or outperform classical methods. In order to train these algorithms, we develop novel techniques to convert historical data into a simulator. On the theoretical side, we present learnability results on a subclass of inventory control problems, where we provide a provable reduction of the reinforcement learning problem to that of supervised learning. On the algorithmic side, we present a model-based reinforcement learning procedure (Direct Backprop) to solve the periodic review inventory control problem by constructing a differentiable simulator. Under a variety of metrics Direct Backprop outperforms model-free RL and newsvendor baselines, in both simulations and real-world deployments.

Embedding based product recommendations have gained popularity in recent years due to its ability to easily integrate to large-scale systems and allowing nearest neighbor searches in real-time. The bulk of studies in this area has predominantly been focused on similar item recommendations. Research on complementary item recommendations, on the other hand, still remains considerably under-explored. We define similar items as items that are interchangeable in terms of their utility and complementary items as items that serve different purposes, yet are compatible when used with one another. In this paper, we apply a novel approach to finding complementary items by leveraging dual embedding representations for products. We demonstrate that the notion of relatedness discovered in NLP for skip-gram negative sampling (SGNS) models translates effectively to the concept of complementarity when training item representations using co-purchase data. Since sparsity of purchase data is a major challenge in real-world scenarios, we further augment the model using synthetic samples to extend coverage. This allows the model to provide complementary recommendations for items that do not share co-purchase data by leveraging other abundantly available data modalities such as images, text, clicks etc. We establish the effectiveness of our approach in improving both coverage and quality of recommendations on real world data for a major online retail company. We further show the importance of task specific hyperparameter tuning in training SGNS. Our model is effective yet simple to implement, making it a great candidate for generating complementary item recommendations at any e-commerce website.
