Python Web Scraping Tools: A Survey
 
40:14
There are myriad web scraping tools available in Python spanning a broad range of use cases. At the same time there are many surprising gaps in coverage. Further complicating matters, differences which look innocuous in a browser can have an outsized impact on the design of an automated browsing system. In this talk we survey a collection of common web scraping frameworks and work out a mapping from real-world use cases to packages. Along the way we address common questions like: How do I choose among content parsers? What if a page is dominated by JavaScript or HTML5? If I'm going to control a browser which one should I choose? Can I run this in the cloud with no access to a display? Can I download files?

Very specific, real-world examples. It covered several instances of 'what is happening', 'what it means' and 'how you fix it'. I was impressed." Steve Welcome to The Top 5 Machine Learning Libraries in Python. This is an introductory course on the process of building supervised machine learning models and then using libraries in a computer programming language called Python. What’s the top career in the world? Doctor? Lawyer? Teacher? Nope. None of those. The top career in the world is the data scientist. Great. What’s a data scientist? The area of study which involves extracting knowledge from data is called Data Science and people practicing in this field are called as Data Scientists. Business generate a huge amount of data. The data has tremendous value but there so much of it where do you begin to look for value that is actionable? That’s where the data scientist comes in. The job of the data scientist is to create predictive models that can find hidden patterns in data that will give the business a competitive advantage in their space. Don’t I need a PhD? Nope. Some data scientists do have PhDs but it’s not a requirement. A similar career to that of the data scientist is the machine learning engineer. A machine learning engineer is a person who builds predictive models, scores them and then puts them into production so that others in the company can consume or use their model. They are usually skilled programmers that have a solid background in data mining or other data related professions and they have learned predictive modeling. In the course we are going to take a look at what machine learning engineers do. We are going to learn about the process of building supervised predictive models and build several using the most widely used programming language for machine learning. Python. There are literally hundreds of libraries we can import into Python that are machine learning related. A library is simply a group of code that lives outside the core language. We “import it” into our work space when we need to use its functionality. We can mix and match these libraries like Lego blocks. Thanks for your interest in the The Top 5 Machine Learning Libraries in Python and we will see you in the course. Who is the target audience? If you're looking to learn machine learning then this course is for you.

Robert Meyer - Analysing user comments with Doc2Vec and Machine Learning classification
 
34:56
Description I used the Doc2Vec framework to analyze user comments on German online news articles and uncovered some interesting relations among the data. Furthermore, I fed the resulting Doc2Vec document embeddings as inputs to a supervised machine learning classifier. Can we determine for a particular user comment from which news site it originated? Abstract Doc2Vec is a nice neural network framework for text analysis. The machine learning technique computes so called document and word embeddings, i.e. vector representations of documents and words. These representations can be used to uncover semantic relations. For instance, Doc2Vec may learn that the word "King" is similar to "Queen" but less so to "Database". I used the Doc2Vec framework to analyze user comments on German online news articles and uncovered some interesting relations among the data. Furthermore, I fed the resulting Doc2Vec document embeddings as inputs to a supervised machine learning classifier. Accordingly, given a particular comment, can we determine from which news site it originated? Are there patterns among user comments? Can we identify stereotypical comments for different news sites? Besides presenting the results of my experiments, I will give a short introduction to Doc2Vec. www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States.

Machine Learning for Time Series Data in Python | SciPy 2016 | Brett Naul
 
24:09
The analysis of time series data is a fundamental part of many scientific disciplines, but there are few resources meant to help domain scientists to easily explore time course datasets: traditional statistical models of time series are often too rigid to explain complex time domain behavior, while popular machine learning packages deal almost exclusively with 'fixed-width' datasets containing a uniform number of features. Cesium is a time series analysis framework, consisting of a Python library as well as a web front-end interface, that allows researchers to apply modern machine learning techniques to time series data in a way that is simple, easily reproducible, and extensible.

The Split-Apply-Combine Pattern for Data Science in Python
 
39:33
Tobias Brandt http://www.pyvideo.org/video/3931/the-split-apply-combine-pattern-for-data-science https://za.pycon.org/talks/12/ Many data science problems involve the application of a split-apply-combine pattern, where you break up a big dataset into independent pieces, operate on each piece in isolation and then put all the pieces back together. This crops up in all stages of a data analysis: * During data preparation, when performing group-wise ranking, standardisation, or normalisation. * During modelling, when fitting separate models to each group. * During communication, when creating summaries or visualisations for display or analysis. Python has many tools that make it easy to utilise this strategy when solving data science problems. These range from list and dictionary comprehensions in the language, the *map* and *reduce* functions and *itertools* and *functools* modules in the standard library to dedicated packages like *Pandas*, *PyToolz*, *Blaze* and *Dask*. Explicit recognition of the applicability of the pattern allows one to reuse standard components for the bookkeeping code that handles the splitting and combining of the independent pieces. This allows one to concentrate on the data analysis code that is unique to the problem at hand. Since implicit in the pattern is the independence of the pieces, its applicability immediately implies a strategy for parallelisation which allows one to easily scale one's solution from single core to out-of-core computation on multiple machines, often with only very few changes to the code required. This talk will introduce the pattern and how to recognise it by presenting some common code blocks. We will then look at some of the tools available, in particular *Pandas* and *PyToolz*, demonstrate their use, and discuss their strengths and weaknesses. Finally we'll show how to take a simple analysis and parallelise it to process a dataset that is too large to fit in memory.

Mining Your Logs - Gaining Insight Through Visualization
 
01:05:04
Google Tech Talk (more info below) March 30, 2011 Presented by Raffael Marty. ABSTRACT In this two part presentation we will explore log analysis and log visualization. We will have a look at the history of log analysis; where log analysis stands today, what tools are available to process logs, what is working today, and more importantly, what is not working in log analysis. What will the future bring? Do our current approaches hold up under future requirements? We will discuss a number of issues and will try to figure out how we can address them. By looking at various log analysis challenges, we will explore how visualization can help address a number of them; keeping in mind that log visualization is not just a science, but also an art. We will apply a security lens to look at a number of use-cases in the area of security visualization. From there we will discuss what else is needed in the area of visualization, where the challenges lie, and where we should continue putting our research and development efforts. Speaker Info: Raffael Marty is COO and co-founder of Loggly Inc., a San Francisco based SaaS company, providing a logging as a service platform.

Text Analysis With SpaCy, NLTK, Gensim, Skearn... - Bhargav Srinivasa Desikan - PyCon Israel 2018
 
28:38
Text Analysis With SpaCy, NLTK, Gensim, Skearn, Keras and TensorFlow The explosion in Artificial Intelligence and Machine Learning is unprecedented now - and text analysis is likely the most easily accessible and understandable part of this. And with python, it is crazy easy to do this - python has been used as a parsing langauge forever, and with the rich set of Natural Language Processing and Computational Linguistic tools, it's worth doing text analysis even if you don't want to. The purpose of this talk is to convince the python community to do text analysis - and explain both the hows and the whys. Python has traditionally been a very good parsing language, aruguably replacing perl for all text file handling tasks. Reading files, regular expressions, writring to files, crawling on the web for textual data have all been standard ways to use python - and now with the Machine Learning and AI explosion - we have a great set of tools in python to understand all the textual data we can so easily play with. I will be briefly talking aboubt the merits, de-merits and use-cases of the most popular text processing libraries. In particular, these will be spaCy, NLTK, gensim. I will also talk about how to use traditional Machine Learning libraries for text analysis, such as scikit-learn, Keras and TensorFlow. Pre-processing is the one of the most important steps of Text Analysis, and I will talk more about this - after all, garbage in, garbage out! The final part of the talk will be about where to get your data - and how to create your own textual data as well. You could analyse anything, from your own emails and whatsapp conversations to freely available British Parliament transcripts!
