"...... some really good people are called perfectionists ". In fact, this description is not accurate. To be more accurate, it should be "they are people who have the ability to be closer to perfection, and they have been working hard ". For example, Hollywood director James Cameron is always called a perfectionist ". The fact that he is constantly pursuing perfection is the premise that he is not only capable but also persistent. In order to produce "Avatar", he prepared for 14 years after f

Liberty Mutual Property Inspection, Winner ' s interview:qingchen WangThe hugely popular Liberty Mutual Group:property inspection Prediction Competition wrapped up on August. With Qin Gchen Wang at the top of a crowded leaderboard. A total of 2,362 players in 2,236 teams competed to predict what many hazards a property inspector would count during a hom E inspection.This blog outlines Qinchen's approach, and how a relative newbie to Kaggle competition

Several novice programmers won the Kaggle Predictive modeling contest after enrolling for a few days of "machine learning" courses on Coursera for free. The big data talent scare that the industry has made in it--McKinsey is the initiator--has raised expectations and demands for big data and advanced analytics talent, and data scientists have become the sexiest career of the night, with its halo chasing sports stars. Data scientists are portrayed as G

started competing on Kaggle?With all my experience, I decided my area of greatest interest lay in analysing complex data. I also quickly realised that my coding skills were from the previous century and thus I opted to learn python. Perhaps the best-of-learn a programming language is to actually does something in it and this led me to Kaggle.Peter ' s top competition finishesDo you have any prior experience or domain knowledge that helped you succeed

The core of the item-based collaborative filtering recommendation algorithm is to generate the final recommendation result by scoring the nearest neighbor of the target item, the user's score on the target item is approached by the weighted average value of the user's score on the nearest neighbor of the target item. For example, in the u

over time, starting here and then there. In theory, objects have been somewhere between two points, but I cannot give a purely philosophical explanation (at least not yet). As time goes by, the object starts at this point, and then it goes to that spot. Frame and Motion The researchers found that images played at 24 frames per second were most likely to be viewed as moving images. Slower than this, it can cause a jump frame due to a longer pause time, which destroys the coherence
