Man vs. Machine: Quantitative and Discretionary Equity Management∗
I use a machine learning technique to classify the universe of active US equity mutual funds as quantitative , who mostly rely of computer-driven models and xed rules, or discretionary , who mostly rely on human judgement. I rst document several new facts about quantitative investing. I then propose an equilibrium model in which quantitative funds have a greater information processing capacity ...
متن کاملMan vs. Machine: Practical Adversarial Detection of Malicious Crowdsourcing Workers
Recent work in security and systems has embraced the use of machine learning (ML) techniques for identifying misbehavior, e.g. email spam and fake (Sybil) users in social networks. However, ML models are typically derived from fixed datasets, and must be periodically retrained. In adversarial environments, attackers can adapt by modifying their behavior or even sabotaging ML models by polluting...
متن کاملFully Automated Enhanced Tumor Compartmentalization: Man vs. Machine Reloaded
OBJECTIVE Comparison of a fully-automated segmentation method that uses compartmental volume information to a semi-automatic user-guided and FDA-approved segmentation technique. METHODS Nineteen patients with a recently diagnosed and histologically confirmed glioblastoma (GBM) were included and MR images were acquired with a 1.5 T MR scanner. Manual segmentation for volumetric analyses was pe...
متن کاملSolitaire: Man Versus Machine
In this paper, we use the rollout method for policy improvement to analyze a version of Klondike solitaire. This version, sometimes called thoughtful solitaire, has all cards revealed to the player, but then follows the usual Klondike rules. A strategy that we establish, using iterated rollouts, wins about twice as many games on average as an expert human player does.
متن کاملMan – Machine Interface
Agents trained by learning techniques provide a powerful approximation of state spaces in games that are too large for naive approaches. In the study Genetic Algorithms and Manual Interface was implemented and used to train agents for the board game LUDO. The state space of LUDO is generalized to a small set and encoded to suit the different techniques. The impact of variables and tactics appli...
