As you may have heard, functions with yield are called generator (generators) in Python, what is generator? Let's put aside the generator and show the concept of yield with a common programming topic. How to generate Fibonacci numbers the Fibonacci (Fibonacci) number is a very simple recursive sequence, with the addition of the first and second numbers, any numbers can be added together by the first two numbers. Using a computer program to output the Fibonacci number of the first N numbers is a ...
Milk is a machine learning kit in Python. Its focus is to provide supervised classifications and several effective classification analyses: SVMs (based on LIBSVM), nn, stochastic forest economy and decision tree. It also performs feature selection. These classifications can be combined in many ways to form different classification systems. For unsupervised learning, milk supports K clustering and affinity propagation. Milk 0.4.0 new features: Parallel processing, perceptron and error-correcting output codes. Enhancements: Setting random seeds in a random forest economy, Defau ...

Introduction: It is well known that R is unparalleled in solving statistical problems. But R is slow at data speeds up to 2G, creating a solution that runs distributed algorithms in conjunction with Hadoop, but is there a team that uses solutions like python + Hadoop? R Such origins in the statistical computer package and Hadoop combination will not be a problem? The answer from the king of Frank: Because they do not understand the characteristics of R and Hadoop application scenarios, just ...
