Practical Machine Learning - Part 1 contains:
- Basic notations of ML (what tasks are there, what is a model, how to measure performance)
- A couple of examples of problems and solutions (taken from previous work)
- A brief presentation of open-source software used for ML (R, scikit-learn, Weka)

Wholi: The right people find each other (at the right time)
Two key elements in this talk:
•PART 1: Machine learning for entity extraction
Natural language processing (NLP), information extraction
•PART 2: Matching profiles using deep learning classifier
Deep learning, word embeddings
Deep neural networks for matching online social networking profilesTraian Rebedea
> Proposed a large dataset for matching online social networking profiles
›This allowed us to train a deep neural network for profile matching using both domain-specific features and word embeddings generated from textual descriptions from social profiles
›Experiments showed that the NN surpassed both unsupervised and supervised models, achieving a high precision (P = 0.95) with a good recall rate (R = 0.85)
Detecting and Describing Historical Periods in a Large CorporaTraian Rebedea
Many historic periods (or events) are remembered
by slogans, expressions or words that are strongly linked to them. Educated people are also able to determine whether a particular word or expression is related to a specific period in human history. The present paper aims to establish correlations between significant historic periods (or events) and the texts written in that period. In order to achieve this, we have developed a system that automatically links words (and topics discovered using Latent Dirichlet Allocation) to periods of time in the recent history. For this analysis to be relevant and conclusive, it must be undertaken on a representative set of texts written throughout history. To this end, instead of relying on manually selected texts, the Google Books Ngram corpus has been chosen as a basis for the analysis. Although it provides only word n-gram statistics for the texts written in a given year, the resulting time series can be used to provide insights about the most important periods and events in recent history, by automatically linking them with specific keywords or even LDA topics.
