Collective Probabilistic Factor Model


The grass is greener on the other side...

Be inspired!

Stories and more stories...

Be informed!

The devil is in the details...

Be challenged!


Our Education SystemEverybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.


Words of Wisdom

The GOOD universities focus on counting the number of publications…

The BETTER universities focus on citation numbers and impact factors…

The BEST universities focus on EDUCATION!


What Is Big Education?

Mr. Big Data + Ms. Education


VALUE!


Seven Typical Tasks• Querying: spherical range-search O(N), orthogonal range-search O(N), nearest-

neighbor O(N), all-nearest-neighbors O(N2)

• Density estimation: mixture of Gaussians, kernel density estimation O(N2), kernel conditional density estimation O(N3)

• Classification: decision tree, nearest-neighbor classifier O(N2), kernel discriminant analysis O(N2), support vector machine O(N3), Lp SVM

• Regression: linear regression, kernel regression O(N2), Gaussian process regression O(N3), LASSO

• Dimension reduction: PCA, non-negative matrix factorization, kernel PCA O(N3), maximum variance unfolding O(N3), Gaussian graphical models, discrete graphical models

• Clustering: k-means, mean-shift O(N2), hierarchical (FoF) clustering O(N3)

• Testing and matching: MST O(N3), bipartite cross-matching O(N3), n-point correlation 2-sample testing O(Nn), kernel embedding


Seven “Giants” of Data

• Basic statistics: means, covariances, etc.

• Generalized N-body problems: distances, geometry

• Graph-theoretic problems: discrete graphs

• Linear-algebraic problems: matrix operations

• Optimizations: unconstrained, convex

• Integrations: general dimension

• Alignment problems: dynamic programming, matching


Seven General Strategies

• Divide and conquer/indexing (trees)

• Function transforms (series)

• Sampling (Monte Carlo, active learning)

• Locality (caching, hashing)

• Streaming (online)

• Parallelism (clusters, GPUs)

• Problem transformation (reformulations)

KEEPSearch KEEPollKEEPCourseKEEPCatalog

Enter a keyword, one click will open the

door to the amazing world of academia.

A real-time web and mobile classroom-polling service with

instant survey results.

Provide the best courses online from top universities and

institutions.

We recommend to you the most popular and

useful products for teaching and learning.


KEEP Searching

Compare with other search engines which just search everything, or some websites like Courser which is too specific. Under KEEPSearch, you get the best of both worlds.

We only collect and organize education related resources to bring the efficient way for people to retrieve accessible and useful materials.

KEEPSearch have already got more than 7 million different kinds of resources. We will increase the spider cluster and keep crawling.

KEEPSearch


Organize and Review

Educators and learners are overwhelmed with an array of choices when it comes to selecting the right technologies for every day use. We recommend you the most popular and useful products for teaching and learning. We also provide product reviews with ratings and recommendations.

KEEPCatalog


MOOC/LMS IntegrationLMS/MOOC hosting service. Promotes the sharing of courses to expedite the development of blended learning and flip-classroom pedagogies.

We index courses from major MOOC players such as Coursera, edX, xuetangX, Udacity, ewant and many more.

We also provide LMS platforms such as MOODLE, Open edX, (Open Canvas in beta version) for teachers to teach online using KEEPCourse.

KEEP Polling

• KEEPoll is a real-time web and mobile classroom polling service.

• A KEEP user could set up free poll, and participants could answer the poll using web browser or mobile SMS.

• Response of poll could be viewed instantly on the web and/or downloaded as CSV or Excel file. Teachers can use self-designed polls to facilitate classroom discussions, thereby creating a more interactive classroom, arousing students' learning interest, and improving students engagement.

MOBILE

The KEEP Cloud will explore and analyze every user’s click to find the hidden patterns and relationships. The analytics can be used to recommend personalized learning programs and services for students, educators and administrators.

Learning and education analytics

In an effort to make eLearning more fun and engaging, game-theoretic-based learning and gaming technology can be used to encourage learners to explore and learn as they move toward the finishing line.

Gamification

KEEP Cloud makes use of social networks to link the users into special interest groups. The social collaboration will turn the individual learning to group/community learning.

Social and collaborative enhancement tools

Mobile apps and wearable technology from KEEP will further help users to enhance their learning and teaching experience through personalized devices.
