Implementing Poincaré Embeddings

Jayant Jain gensim, Open Source Leave a Comment

I have been working on implementing a model called Poincaré embeddings over the last month or so. The model is from an interesting paper by Facebook AI Research – Poincaré Embeddings for Learning Hierarchical Representations [1]. This post describes the model at a relatively high level of abstraction, and the detailed technical challenges faced in the process of implementing it.

New download API for pretrained NLP models and datasets in Gensim

Chaitali Saini Datasets, gensim, Open Source, Student Incubator 2 Comments

There’s no shortage of websites and repositories that aggregate various machine learning datasets and pre-trained models (Kaggle, UCI MLR, DeepDive, individual repos like gloVe, FastText, Quora, blogs, individual university pages…). The only problem is, they all use widely different formats, cover widely different use-cases and go out of service with worrying regularity. For this reason, we decided to include free …

Machine learning benchmarks: Hardware providers (part 1)

Shiva Manne Machine Learning, Open Source, Student Incubator 10 Comments

The rise of machine learning as a discipline brings new demands for number crunching and computing power. With easily accessible and cheap hardware resources, one has to pick the right platform to run the experiments and model training on. Should you use Amazon’s AWS EC2 instances? Or go with IBM’s Softlayer, Google’s Compute Engine, Microsoft’s Azure? How about a real …

The Mummy Effect: Bridging the gap between academia and industry (PyData keynote)

Radim Řehůřek Machine Learning, Open Source, Student Incubator

Last month, I gave a keynote at PyData Warsaw about the existing (and growing) gap between academia and industry, specifically when it comes to machine learning / data science. This is a topic close to my heart, since we’ve operated in that no-man’s land where academia and industry collide for a living for 7 years now. Between running our Student …

Counting Efficiently with Bounter pt. 1: HashTable

Filip Štefaňák Machine Learning, Open Source Leave a Comment

Have you heard about the new open source Bounter Python library in town? In case you can’t wait to use it in practice but are wary of its “frequency estimation”, and what kind of results you can expect, this series of blog posts will help you develop the right intuition. It is split into two parts, one for each of …

Data analysis in Python: Interactive confusion matrix with Facets Dive, Pandas, Scikit-learn

Jan Pomikálek Machine Learning, Open Source Leave a Comment

The Facets project by Google’s “People+AI Research Initiative” (PAIR) offers two open source visualization tools for data analytics – Facets Overview and Facets Dive. Today, we are going to look at Facets Dive and demonstrate how to use it for an interactive confusion matrix for a multiclass classification problem using Python, Pandas and Scikit-learn.

Gensim switches to semantic versioning

Lev Konstantinovskiy gensim, Open Source

Starting with release 1.0.0, Gensim adopts semantic versioning. The time went in a flash, but Gensim has reached maturity. It's been cited in nearly 500 academic papers, used commercially in dozens of companies, organized many coding sprints and meetups and generally withstood the test of time. Between the continued Gensim support by our parent company, rare-technologies.com, and our open Student ...
