organizing hackathon

When hackathon encounters full-stack engineers and hackathon encountersOn February 24, April 17, he participated in the HackAthon24 hackathon organized by Sina Weibo platform architecture. I think it's the first time I 've participated in this type of technical activity. I feel novel and passionate. In fact, I feel that the back-end engineers have little advantag

I'm glad to have won the hackathon championship this time! The accuracy of our music prediction algorithm reaches RMSE = 13.24598. The implicit feedbacks of SVD ++ did not play a major role this time. On the contrary, 86 feature columns in words are of great help and used in logistic regression. In addition, the combination of various profiles, items, and artist of users also brings good results. The competition is described as follows:Competition go

On October 6, July 5, 2014, AVOS cloud joined forces with dynamic technology, qiniu cloud storage, ucloud, Intranet push, segmentfault, EOE developer community, 100 offer, csdn, and geek college to reach the magic capital, A two-day hackathon competition was held for developers. This activity was exclusively co-sponsored by moji.com to provide special reports on developers' ideas and products. As the guardian of mobile application security, love encry

Last weekend participated in the IBM Analytics held "Big Data Hackathon" Beijing Station competition, 4 people team to get the first place, very happy, also very difficult, we four wesor like to work together for a long time, their respective cooperation with tacit understanding, Won the final trophy. The first day from 9 o'clock to 11 o'clock more, I would like to stay up late but limited to the organizer of the venue, the next day 9 o'clock to three

Self-organizing neural network, also known as self-organizing competitive neural network, is especially suitable for solving the problem of pattern classification and recognition. The network model belongs to the Feedforward neural network model, using unsupervised learning algorithm, the basic idea of the work is to let each neuron of competition layer match the input mode, and finally only one neuron beco

In agile self-organizing teams, the word "self-organizing" may not be too accurate and does not conform to the definition of the word "Organization". Therefore, the word "self-guided team" is sometimes used. Self-Organizing teams in Agile must be created from outside rather than spontaneously organized together. It is a team created from outside, authorized, and

Nowadays, the Office is increasingly dependent on email. It is nothing new to receive hundreds of emails a day. If you use email more effectively than making it an office time killer, Glenn introduces six tips on organizing emails on his blog: Change the email check interval to 15 to 30 minutes. If you do not need one email, you can stop your work and process it at a specific time every hour. Create three folders: "To be processed", "intereste

By properly organizing the basic actions of the connected device structure, we can accomplish some slightly more complex functions, which are expressed by specific names, which are the instructions we call.We want to design a data through the instructions given, can complete the arithmetic operation, and can send the result of the operation to the register out of the output of the CPU. Based on the needs of this task, we can design some basic function
