Apriori Algorithm (Associated Learning) - Fun and Easy Machine Learning https://www.udemy.com/machine-learning-fun-and-easy-using-python-and-keras/?couponCode=YOUTUBE_ML Limited Time - Discount Coupon Apriori Algorithm The Apriori algorithm is a classical algorithm in data mining that we can use for these sorts of applications (i.e. recommender engines). So It is used for mining frequent item sets and relevant association rules. It is devised to operate on a database containing a lot of transactions, for instance, items brought by customers in a store. It is very important for effective Market Basket Analysis and it helps the customers in purchasing their items with more ease which increases the sales of the markets. It has also been used in the field of healthcare for the detection of adverse drug reactions. A key concept in Apriori algorithm is that it assumes that: 1. All subsets of a frequent item sets must be frequent 2. Similarly, for any infrequent item set, all its supersets must be infrequent too.

Text Analytics - Ep. 25 (Deep Learning SIMPLIFIED)
Unstructured textual data is ubiquitous, but standard Natural Language Processing (NLP) techniques are often insufficient tools to properly analyze this data. Deep learning has the potential to improve these techniques and revolutionize the field of text analytics. Deep Learning TV on Facebook: https://www.facebook.com/DeepLearningTV/ Twitter: https://twitter.com/deeplearningtv Some of the key tools of NLP are lemmatization, named entity recognition, POS tagging, syntactic parsing, fact extraction, sentiment analysis, and machine translation. NLP tools typically model the probability that a language component (such as a word, phrase, or fact) will occur in a specific context. An example is the trigram model, which estimates the likelihood that three words will occur in a corpus. While these models can be useful, they have some limitations. Language is subjective, and the same words can convey completely different meanings. Sometimes even synonyms can differ in their precise connotation. NLP applications require manual curation, and this labor contributes to variable quality and consistency. Deep Learning can be used to overcome some of the limitations of NLP. Unlike traditional methods, Deep Learning does not use the components of natural language directly. Rather, a deep learning approach starts by intelligently mapping each language component to a vector. One particular way to vectorize a word is the “one-hot” representation. Each slot of the vector is a 0 or 1. However, one-hot vectors are extremely big. For example, the Google 1T corpus has a vocabulary with over 13 million words. One-hot vectors are often used alongside methods that support dimensionality reduction like the continuous bag of words model (CBOW). The CBOW model attempts to predict some word “w” by examining the set of words that surround it. A shallow neural net of three layers can be used for this task, with the input layer containing one-hot vectors of the surrounding words, and the output layer firing the prediction of the target word. The skip-gram model performs the reverse task by using the target to predict the surrounding words. In this case, the hidden layer will require fewer nodes since only the target node is used as input. Thus the activations of the hidden layer can be used as a substitute for the target word’s vector. Two popular tools: Word2Vec: https://code.google.com/archive/p/word2vec/ Glove: http://nlp.stanford.edu/projects/glove/ Word vectors can be used as inputs to a deep neural network in applications like syntactic parsing, machine translation, and sentiment analysis. Syntactic parsing can be performed with a recursive neural tensor network, or RNTN. An RNTN consists of a root node and two leaf nodes in a tree structure. Two words are placed into the net as input, with each leaf node receiving one word. The leaf nodes pass these to the root, which processes them and forms an intermediate parse. This process is repeated recursively until every word of the sentence has been input into the net. In practice, the recursion tends to be much more complicated since the RNTN will analyze all possible sub-parses, rather than just the next word in the sentence. As a result, the deep net would be able to analyze and score every possible syntactic parse. Recurrent nets are a powerful tool for machine translation. These nets work by reading in a sequence of inputs along with a time delay, and producing a sequence of outputs. With enough training, these nets can learn the inherent syntactic and semantic relationships of corpora spanning several human languages. As a result, they can properly map a sequence of words in one language to the proper sequence in another language. Richard Socher’s Ph.D. thesis included work on the sentiment analysis problem using an RNTN. He introduced the notion that sentiment, like syntax, is hierarchical in nature. This makes intuitive sense, since misplacing a single word can sometimes change the meaning of a sentence. Consider the following sentence, which has been adapted from his thesis: “He turned around a team otherwise known for overall bad temperament” In the above example, there are many words with negative sentiment, but the term “turned around” changes the entire sentiment of the sentence from negative to positive. A traditional sentiment analyzer would probably label the sentence as negative given the number of negative terms. However, a well-trained RNTN would be able to interpret the deep structure of the sentence and properly label it as positive.

Hierarchical Clustering - Fun and Easy Machine Learning
Hierarchical Clustering - Fun and Easy Machine Learning with Examples https://www.udemy.com/machine-learning-fun-and-easy-using-python-and-keras/?couponCode=YOUTUBE_ML Hierarchical Clustering Looking at the formal definition of Hierarchical clustering, as the name suggests is an algorithm that builds hierarchy of clusters. This algorithm starts with all the data points assigned to a cluster of their own. Then two nearest clusters are merged into the same cluster. In the end, this algorithm terminates when there is only a single cluster left. The results of hierarchical clustering can be shown using Dendogram as we seen before which can be thought of as binary tree Difference between K Means and Hierarchical clustering Hierarchical clustering can’t handle big data well but K Means clustering can. This is because the time complexity of K Means is linear i.e. O(n) while that of hierarchical clustering is quadratic i.e. O(n2). In K Means clustering, since we start with random choice of clusters, the results produced by running the algorithm multiple times might differ. While results are reproducible in Hierarchical clustering. K Means is found to work well when the shape of the clusters is hyper spherical (like circle in 2D, sphere in 3D). K Means clustering requires prior knowledge of K i.e. no. of clusters you want to divide your data into. However with HCA , you can stop at whatever number of clusters you find appropriate in hierarchical clustering by interpreting the Dendogram.

How DTW (Dynamic Time Warping) algorithm works
In this video we describe the DTW algorithm, which is used to measure the distance between two time series. It was originally proposed in 1978 by Sakoe and Chiba for speech recognition, and it has been used up to today for time series analysis. DTW is one of the most used measure of the similarity between two time series, and computes the optimal global alignment between two time series, exploiting temporal distortions between them. Source code of graphs available at https://github.com/tkorting/youtube/blob/master/how-dtw-works.m The presentation was created using as references the following scientific papers: 1.

Frequent Pattern Mining Programming
https://goo.gl/3dhnWH Programming assignment might take more time than written assignments, and it counts as 10% of your final grade, so please start early. This is an individual assignment, which means it is OK to discuss with your classmates and your TAs regarding the methods, but it is not OK to work together or share code. Similar libraries or programs of frequent pattern mining algorithms can be found on-line, but you are prohibited to use these resources directly, which means you can not include public libraries, or modify existing programs, since the purpose of this programming assignment is to help you go through frequent pattern mining processing step by step. You can use either Java/C++/Python as your programming language. You will use a package working under OS with Unix kernel. It works well on Linux/MacOS. If you are a Windows user, you need to either (1) connect to an EWS lab machine or (2) find other packages with the same function. You are asked to write a report about the assignment. So pay attention to the places with "Question to ponder" PaperID Title 7600 The Automatic Acquisition of Proof Methods 85825 Frequent pattern discovery with memory constraint For this assignment, we pre-processed the raw data by removing stop words, converting the words to lower cases and Objective Explore how frequent pattern mining can be applied to text mining to discover meaningful phrases. In this assignment, you will first run LDA on a corpus made up of titles from 5 domains' conference papers. Based on the results from LDA, a topic (representing a particular domain) is assigned to each word in each title. Then you write a frequent mining algorithm to mine frequent patterns from each topic to get meaningful phrases. The mined frequent patterns may not necessarily be *meaningful* phrases for the topic. So you will consider the question how to extract meaningful ones out of all the frequent patterns. The final goal is to output highly representative phrases for each topic. Step 1: Get to Know the Data We collect paper titles from conferences in computer science of 5 domains: Data Mining(DM), Machine Learning(ML), Database(DB), Information Retrieval(IR) and Theory(TH). You can download the raw data here paper_raw.txt. (Note that we will not use this file directly for this assignment. But you can look at this file to see what the original titles look like.) Each line contains two columns, PaperID and Title of a paper, separated by Tab('\t'). Recall the example in class. For each line in the file you can consider it as one transaction. Each word in the title is equivalent to an item in a transaction. Note that PaperID is unique in the whole data set. However, since this data is a subset of all the paper titles from a large corpus, PaperIDs are not starting from 0 and not consecutive. The raw data looks like this:

Data Science Design Patterns
Tennessee Leeuwenburg https://2016.pycon-au.org/schedule/78/view_talk Most 'data science' projects fall into just a few well-understood design patterns. This talk de-mystifies what those patterns are, how to use them practically, and how to get to grips with your data. We'll a look at how to understand the input/output structure of the models, how to design a reasonable 'experiment', and how to get started. We'll look at getting to grips with problems by simple data sets that can fit entirely on-screen, designing the basic 'form' of the machine before levelling up to bigger data and badder algorithms. All of this will be shown using Python tools, libraries and running code.

Ben Chamberlain - Real time association mining in large social networks
PyData London 2016 Social media can be used to perceive the relationships between individuals, companies and brands. Understanding the relationships between key entities is of vital importance for decision support in a swathe of industries. We present a real-time method to query and visualise regions of networks that could represent an industries, sports or political parties etc. There is a growing realisation that to combat the waning effectiveness of traditional marketing, social media platform owners need to find new ways to monetise their data. Social media data contains rich information describing how real world entities relate to each other. Understanding the allegiances, communities and structure of key entities is of vital importance for decision support in a swathe of industries that have hitherto relied on expensive, small scale survey data. We present a real-time method to query and visualise regions of networks that are closely related to a set of input vertices. The input vertices can define an industry, political party, sport etc. The key idea is that in large digital social networks measuring similarity via direct connections between nodes is not robust, but that robust similarities between nodes can be attained through the similarity of their neighbourhood graphs. We are able to achieve real-time performance by compressing the neighbourhood graphs using minhash signatures and facilitate rapid queries through Locality Sensitive Hashing. These techniques reduce query times from hours using industrial desktop machines to milliseconds on standard laptops. Our method allows analysts to interactively explore strongly associated regions of large networks in real time. Our work has been deployed in Python based software and uses the scipy stack (specifically numpy, pandas, scikit-learn and matplotlib) as well as the python igraph implementation.

29 Python Regular Expressions | Python Tutorial | learn python scripting | Learnbay
Regular expressions are used to solve a common problem: Given a string, determine whether that string matches a given pattern and, optionally, collect substrings that contain relevant information. Below topics are covered in this tutorial: 1: What is regular expression ? 2: What is pattern matching ? 3: What is re module ? 4: How to check Matching character in bracket , matching character not in bracket. 5: Basic Regular Expressions operations in detail. Course Feature: Course Features:- 1.Practical training and hands on Real Time Project Implementation With Assignment.Course includes mini projects/Real time industry level project with tons of assignment and exercises. 2.Expert Instructor Instructors from tier one product based MNC, from IITs/NITs 3.Placement Assistance: Interview Guidance And Placement assistance for job seekers. 4.Limited Batch Size. Limited Batch size for more personal attention during the course. 5.Project Support Real time project support. About the Course LearnBay's Python (Online/In-person) Certification Training (Novice to Expert). This course is for those For those - who wanted to build their career as a python developer and want to learn python for network automation, python for AWS , python for Data science, Python for automating test-cases and interested to get in-depth knowledge in python, This course will help you in becoming python expert, No prior knowledge of python is required to take up this course, even beneficial for those who are form non programming background and wanted to learn python to become data scientist. Teaching Python or any other technical training to those who are not from Technical background or form non coding (not from Computer Science ) background is always challenging, since we always have to teach them form basic and in more detail, It takes more time and effort, So keeping this challenge in mind Learnbay has design its course content and assignment in such a way that even harder concept can be explained in a very simple and clean way, Memory layout concept is very important for both who are from technical and non technical background, because if you can imagine the underlying memory layout of a program you can code it very easily irrespective of the language used. Where you will be learning all the basics and advance concept in python which includes, memory layout of a python program , python data structures like list, tuple, dictionary, you will be learning which data structure to use when, while solving real word problem.
