Learn to Analyze Text Data in Bash Shell and Linux (Course Organization)
 
01:28
1000+ students have taken this innovative project-based data learning course (includes video lectures and an eBook with source codes and data sets) "Learn to Analyze Text Data in Bash Shell and Linux " https://school.scientificprogramming.io/learn-to-analyze-text-data-in-bash-shell-and-linux-video-lectures Can you build a script to count the number of sequences in a Big data consisting hundred thousands of nucleotide sequences in 30 seconds? You may wonder to know, this wouldn't take more a than a few words in Bash! Three simple projects to demonstrate the use of Bash shell in processing csv formatted text data sets. This course starts with some practical bash-based flat file data mining projects involving: University ranking data Facebook data Crime Data There are several examples of practical data mining that will have a flow of importing specific data resources into flat text-type files. Bash can run different programs (grep, sort, sed, and so on) on those files, clean, optimise and extract preliminary views (cut, csvlook, view, cat, head, etc.) of the data. There is one part of data mining, which involves unstructured data and then transforming it into a structured one (awk, shell). A scripting language like Bash can be very useful for doing the transformation.
Log File Frequency Analysis with Python
 
01:00:53
Information Security professionals often have reason to analyze logs. Whether Red Team or Blue Team, there are countless times that you find yourself using "grep", "tail", "cut", "sort", "uniq", and even "awk"! While these powerful UNIX methods take us far, there is always that time when you want more power! In this webcast, Joff Thyer will discuss using Python regular expressions, and dictionaries to extract useful data for frequency analysis. If you want to learn even more about Python, join Joff for SANS SEC573 - "Automating Information Security with Python" www.sans.org/sec573 Slides available here: https://www.blackhillsinfosec.com/webcast-log-file-frequency-analysis-python/

Text Mining with Node.js - Philipp Burckhardt, Carnegie Mellon University
 
20:19
Text Mining with Node.js - Philipp Burckhardt, Carnegie Mellon University Today, more data is accumulated than ever before. It has been estimated that over 80% of data collected by businesses is unstructured, mostly in the form of free text. The statistical community has developed many tools for analyzing textual data, both in the areas of exploratory data analysis (e.g. clustering methods) and predictive analytics. In this talk, Philipp Burckhardt will discuss tools and libraries that you can use today to perform text mining with Node.js. Creative strategies to overcome the limitations of the V8 engine in the areas of high-performance and memory-intensive computing will be discussed. You will be introduced to how you can use Node.js streams to analyze text in real-time, how to leverage native add-ons for performance-intensive code and how to build command-line interfaces to process text directly from the terminal.

The script should be quite easy to read now as we use a while loop to read in the CSV file. We change the file delimiter to be the comma and then we have the line that we read in broken up into the schema elements we need. A report then is easy with colours and search ability.

44:01
Evaluating Text Extraction: Apache Tika's™ New Tika-Eval Module - Tim Allison, The MITRE Corporation Text extraction tools are essential for obtaining the textual content and metadata of computer files for use in a wide variety of applications, including search and natural language processing tools. Techniques and tools for evaluating text extraction tools are missing from academia and industry. Apache Tika™ detects file types and extracts metadata and text from many file types. Tika is a crucial component in a wide variety of tools, including Solr™, Nutch™, Alfresco, Elasticsearch and Sleuth Kit®/Autopsy®. In this talk, we will give an overview of the new tika-eval module that allows developers to evaluate Tika and other content extraction systems. This talk will end with a brief discussion of the results of taking this evaluation methodology public and evaluating Tika on large batches of public domain documents on a public vm over the last two years. About Tim Allison Tim has been working in natural language processing since 2002. In recent years, his focus has shifted to advanced search and content/metadata extraction. Tim is committer and PMC member on Apache PDFBox (since September 2016), and on Apache POI and Apache Tika since (July, 2013). Tim holds a Ph.D. in Classical Studies from the University of Michigan, and in a former life, he was a professor of Latin and Greek.

TensorFlow is one of the best libraries to implement Deep Learning. TensorFlow is a software library for numerical computation of mathematical expressions, using data flow graphs. Nodes in the graph represent mathematical operations, while the edges represent the multidimensional data arrays (tensors) that flow between them. It was created by Google and tailored for Machine Learning. In fact, it is being widely used to develop solutions with Deep Learning. Machine learning is one of the fastest-growing and most exciting fields out there, and Deep Learning represents its true bleeding edge. Deep learning is primarily a study of multi-layered neural networks, spanning over a vast range of model architectures. Traditional neural networks relied on shallow nets, composed of one input, one hidden layer and one output layer. Deep-learning networks are distinguished from these ordinary neural networks having more hidden layers, or so-called more depth. These kinds of nets are capable of discovering hidden structures within unlabeled and unstructured data (i.e. images, sound, and text), which constitutes the vast majority of data in the world.

Process big text file, extract all lines containing specified sub-strings
 
03:08
String Master (by http://ChaosCoder.Com) is designed to split one string data source file into two or more files in accordance with the chosen mask or substrings. Main application areas of the software are the search of the required entries in the database, forum and web log dumps, text files of large volume, automation of the reference database sorting by domains and names. String Master reads the source file information string by string, verifies its compliance with the specified substrings or mask before putting in buffer. As the buffer fills the sorted data is stored in files, the names of which duplicate the name of the initial file with the addition of the sorting numbers of masks in the program list. Strings that do not match any of the user-defined masks are recorded in the file with a zero. When Split by Masks - Single (F3) is selected, files are created according to the number of masks / substrings; each file is given a name composed of the source file’s name and the sorting number of the mask or substring. When naming the base.txt source file and all the links displayed in the default substrings containing «. Com /», will be saved in a file named base.txt.1.txt; containing «. Net /» - to file base.txt .2. txt; containing «. org /» - to file base.txt.3.txt, and so on. If a line corresponding to several substrings or masks is found, then it will be placed only in the file with a mask placed higher in the list. If in addition, if there are lines not suiting any mask or substring, then will be they will be placed in a file bearing the source name and the index 0. Of course, String Master is not only suitable for working with lists of links, and a variety of databases of forums and websites. Through a stable and fast work with large files this program can have lots of other uses. Attention! StringMasters reduces the processing speed when executed the second time without being restarted. In order to avoid sudden drop in speed, simply change the buffer size like shown in the present video and the speed of processing will raise to a possible maximum!

https://drive.google.com/open?id=1yRTuRPLNpLQRI1zEcq9Gx3N6WTcBCqMP What is Machine Learning? Machine learning is a field of computer science that uses statistical techniques to give computer systems the ability to "learn" (e.g., progressively improve performance on a specific task) with data, without being explicitly programmed. Machine learning is closely related to (and often overlaps with) computational statistics, which also focuses on prediction-making through the use of computers. It has strong ties to mathematical optimization, which delivers methods, theory and application domains to the field. Machine learning is sometimes conflated with data mining, where the latter subfield focuses more on exploratory data analysis and is known as unsupervised learning.
