Redis - Evaluating information retrieval with NDCG@K & Redis

“Evaluating information retrieval (IR) systems is essential for informed design decisions and understanding system performance. Successful companies like Amazon and Google rely heavily on IR systems, with Amazon attributing over 35% of sales and Google 70% of YouTube views to their recommender systems. Effective evaluation measures are key to building and refining these systems.”

Apple Machine Learning - DR-MPC: Deep Residual Model Predictive Control for Real-World Social Navigation

How can a robot safely navigate around people exhibiting complex motion patterns? Reinforcement Learning (RL) or Deep RL (DRL) in simulation holds some promise, although much prior work relies on simulators that fail to precisely capture the nuances of real human motion. To address this gap, we propose Deep Residual Model Predictive Control (DR-MPC), a method to enable robots to quickly and safely perform DRL from real-world crowd navigation data.
