Words similarity

Finding words (sentences, documents) with the same meaning is general problem for NLP (Natural Language Processing). Deep learning helps improve this field of science.
For example, word2vec approach helps you derive from text corpus some things with relationship like "man to king" as "women to ?". And "?" should be replaced by "queen". It's amazing stuff. In addition, you can train not just similarity word-to-word but also word-to-sequence of words.
Here is some examples from model  which were trained on  Google News corpus:

Spark for Data Science

In June you can learn with EdX "how to apply data science techniques using parallel programming in Apache Spark to explore big (and small) data". It will be "Introduction to Big Data with Apache Spark" course from Berkeley.

Data Quality Checklist for Process Mining

Nice paper from Fluxicon about basic problems in process mining workflow, how to discover and fix them.

Process Mining: Data Science in Action by Coursera

This is  my short feedback for Coursera Process Mining course (by Wil van der Aalst from Eindhoven University of Technology)
Name of the course sounds very interesting, but the main task is quite simple.
It's about building behaviour model based on events log(you need to consider overfitting and underfitting). That's mean: your model should explain majority of cases and be general enough for explaining new cases.
Main tools, recommended in the course, are Disco and ProM. They allow building models according to different notations(e.g. BPMN) and making visualisations.
Two main aspects of process mining are organisational and social aspects:
Organisational aspects tasks:

• discover typical workflow actions(for customers, employees, etc)
• analyse of time spent for every tasks
• "bottlenecks" mining

Social aspects tasks:

• discover users groups and users relations within process
• analysis of time spending for every worker, customer, etc

In addition, in both aspects you can recommend next steps or forecast time of completion future tasks.

Visualizing Data using t-SNE

If you need solution for  visualization of high-dimensional datasets- t-SNE  is a great choice.

Dive into Deep Learning

If you are interested in deep learning - you can try UFLDL (Unsupervised Feature Learning and Deep Learning) tutorial from Stanford University.
If this topic is really new for you - it is better to start from https://www.coursera.org/course/ml. After this session course will change format into self-study.
