Learning F# Functional Data Structures and Algorithms is Out!

الحمد للہ رب العالمین

Wondering what to do on 4th of July long weekend? Learn Functional Programming in F# with my book!

I am glad to inform that my book on Learning F# Functional Data Structures and Algorithms is published, and is now available via Amazon and other retailers. F# is a multi-paradigm programming language that encompasses object-oriented, imperative, and functional programming language properties. The F# functional programming language enables developers to write simple code to solve complex problems.

Learning F# Functional Data Structures and Algorithms - Adnan Masood PhD

Starting with the fundamental concepts of F# and functional programming, this book will walk you through basic problems, helping you to write functional and maintainable code. Using easy-to-understand examples, you will learn how to design data structures and algorithms in F# and apply these concepts in real-life projects. The book will cover built-in data structures and take you through enumerations and sequences. You will gain knowledge about stacks, graph-related algorithms, and implementations of binary trees. Next, you will understand the custom functional implementation of a queue, review sets and maps, and explore the implementation of a vector. Finally, you will find resources and references that will give you a comprehensive overview of F# ecosystem, helping you to go beyond the fundamentals.

If you have just started your adventure with F#, then this book will help you take the right steps to become a successful F# coder. An intermediate knowledge of imperative programming concepts, and a basic understanding of the algorithms and data structures in .NET environments using the C# language and BCL (Base Class Library), would be helpful.

With detailed technical and editorial reviews, it is a long process to write a technology book, but equally rewarding and unique learning experience. I am thankful to my technical reviewer, and Packt editorial team to provide excellent support to make this a better book. Nothing is perfect and to err is human; if you find any issues in the code or text, please let me know.

Rendezvous with MIT Bot @ NASA - Sample Return Robot Challenge

The fun thing about spending time at MIT is that you always run into interesting things. Couple of days ago, I encountered the MIT Bot submission for NASA - Sample Return Robot Challenge.



NASA and the Worcester Polytechnic Institute (WPI) in Worcester teamed up for competing in the Sample Return Robot Challenge to demonstrate a robot that can locate and retrieve geologic samples from a wide and varied terrain without human control.

Sample Return Robot Challenge is part of NASA centennial challenges; a robot which has autonomous capability to locate and retrieve specific sample types from various locations over a wide and varied terrain and return those samples to a designated zone in a reasonable amount of time with limited mapping data.

The challenge description follows:

The Sample Return Robot Challenge is scheduled for June 14-17, 2012 in Worcester, MA. The Challenge requires demonstration of an autonomous robotic system to locate and collect a set of specific sample types from a large planetary analog area and then return the samples to the starting zone. The roving area will include open rolling terrain, granular medium, soft soils, and a variety of rocks, and immovable obstacles (trees, large rocks, water hazards, etc.) A pre-cached sample and several other samples will be located in smaller sampling zones within the larger roving area. Teams will be given aerial/geological/topographic maps with appropriate orbital resolution, including the location of the starting position and a pre-cached sample.

MIT Robotics Team 2015 Promo Video

The bot is powered with the following technologies:

ROS: The Robot Operating System (ROS) is a set of software libraries and tools that help you build robot applications. From drivers to state-of-the-art algorithms, and with powerful developer tools, ROS has what you need for your next robotics project. And it's all open source.

Arduino: Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects.

RabbitMQ for Async messaging: RabbitMQ is a messaging broker - an intermediary for messaging. It gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.



MIT team couldn't make it to the challenge due to some technical issues. NASA has awarded $100,000 in prize money to the Mountaineers, a team from West Virginia University, Morgantown, for successfully completing Level 2 of the Sample Return Robot Challenge, part of the agency’s Centennial Challenges prize program.



MIT Machine Learning for Big Data and Text Processing Class Notes - Day 2

So after having an awesome Day 1 @ MIT, I was in CSAIL library and met Pedro Ortega, NIPS 2015 Program Manager @adaptiveagents. Celebrity sighting!

Today on Day 2, Dr. Jaakkola (Bio) (Personal Webpage) professor, Electrical Engineering and Computer Science/Computer Science and Artificial Intelligence Laboratory (CSAIL), went over the following .

  • Non-linear classification and regression, kernels
  • Passive aggressive algorithm
  • Overfitting, regularization, generalization
  • Content recommendation

Dr. Jaakkola's socratic method of inquiring the common sense questions ingrain the common concepts in the mind of people. The class started with the follow up of perceptron from yesterday and quickly turned into a session on when NOT to use perceptron such as in case of non linearly seperable problems. Today's lecture was derieved  from 6.867 Machine Learning Lecture 8. The discussion extended to Support Vector Machine (and Statistical Learning Theory) Tutorial, which is also well explained in the An Idiot’s guide to Support vector machines (SVMs) R. Berwick, Village Idiot joke1

Speaking of SVM and dimensionality, Dr. Jaakkola posed the question if ranking can also be a secondary classification problem? Learning to rank or machine-learned ranking (MLR) is a fascinating topic where common intuitions like number of items displayed, error functions between user's preference and display order sparseness fall flat. Microsoft research has some excellent reference papers and tutorials on learning to rank which are definitely worth pouring over in case you are interested in this topic.  Label ranking by learning pairwise preferences is another topic discussed in detail during the class. Some reference papers follow:

Indeed with SVM, the natural progression led to the 'k' word; kernel functions. A brief introduction to kernel classifiers Mark Johnson Brown University is a good starting point and The difference of kernels in SVM?, and how to select a kernel for SVM provide good background material to understand the practical aspects of kernel.  Kernels and the Kernel Trick Martin Hofmann Reading Club "Support Vector Machines" 



The afternoon topic was Anomaly detection; use cases included aberrant behavior in financial transactions, insurance fraud, bot detection, manufacturing quality control etc. One the most comprehensive presentations on Anomaly Detection Data Mining Techniques is by Francesco Tamberi which is great for the background. Several problems worked on during the class were from 6.867 Machine learning which shows how instructors carefully catered the program for practitioners with the right contents from graduate level courses, as well as industry use cases. Other topics discussed included Linear versus nonlinear classifiers and we learned how decision boundary is the region of a problem space in which the output label of a classifier is ambiguous. Class discussions and Q&A touched on the wide variety of subjects including but not limited to How to increase accuracy of classifiers?Recommendation SystemsA Comparative Study of Collaborative Filtering Algorithms which eventually led to Deep Learning Tutorial: From Perceptrons to Deep Networks which performed really well on MNIST Database for handwritten digits.

Linear vs. non linear classifiers followed where Dr. Jaakkola spoke about why logistic regression a linear classifier, more on Linear classifierKernel Methods for General Pattern AnalysisKernel methods in Machine learningHow do we determine the linearity or nonlinearity of a classification problem? and review of Kernel Methods in Machine Learning


Misc. discussions of Kernel MethodsSo you think you have a power lawRadial basis function kernelKernel Perceptron in Python surfaced, some of which briefly reviewed in Machine Learning: Perceptrons- Kernel Perceptron Learning Part-3/4Shape Fitting with Outliers and SIGIR 2003 Tutorial Support Vector and Kernel Methods tutorial with radial basis functions. Other topics included Kernel based Anomaly Detection with Multiple Kernel Anomaly Detection (MKAD) AlgorithmSupport Vector Machines: Model Selection Using Cross-Validation and Grid-SearchLIBSVM -- A Library for Support Vector MachinesPractical Guide to Support Vector ClassificationOutlier Detection with Kernel Density Functions and Classification Framework for Anomaly Detection as relevant readings.

For a linear Algebra Refresher, Dr. Barzilay recommended Prof. Gilbert Strang MIT Open Course Number 18.06  or Gilbert Strang lectures on Linear Algebra via video lectures.

Looking forward to the Deep Learning and Boosting tomorrow! Dr. Barzilay said its going to be pretty cool.




MIT Machine Learning for Big Data and Text Processing Class Notes - Day 1

As a follow up on MIT's tackling the challenges of Big Data, I am currently in Boston attending Machine Learning for Big Data and Text Processing Classification (and therefore blogging about it for posterity based on public domain data / papers - nothing posted here is MIT proprietary info to violate any T&C). MIT professional education courses are tailored towards professionals and it is always a great opportunity to learn what others practitioners are up to, especially in a relatively new field of data science.

Today's lecture #1 was outlined as

  • machine learning primer
  • features, feature vectors, linear classifiers
  • On-line learning, the perceptron algorithm and
  • application to sentiment analysis

Instructors Tommi Jaakkola (Bio) (Personal Webpage) and Regina Barzilay (Bio) (Personal Webpage) started the discussion with breif overview of the course. Dr. Barzilay is a great teacher who explains the concepts in amazing detail. As an early adapter and practitioner,  she was one of the technology review innovator under 35.

The course notes are fairly comprehensive; following are the links to the publicly available material.

  • Youtube:
  • FB:
  • twitter:
  • LinkedIn -

In collaboration with CSAIL - MIT Computer Science and AI Lab-, today's lecture was a firehose version of Ulman's large scale machine learning. Dr. Barzilay walked through the derivation of the Perceptron Algorithm, covering Perceptrons for Dummies and Single Layer Perceptron as Linear Classifier. For a practical implementation, Seth Juarez's NUML implementation of perceptron is a good reading. A few relevant publications can be found here.

The discussion progressed into Opinion Mining and Sentiment Analysis with related techniques. Some of the pertinent data sets can be found here:

Dr. Barzilay briefly mentioned Online Passive-Aggressive Algorithms  and details from Lillian Lee, AAAI 2008 Invited Talk - A “mitosis” encoding / min-cost cut while talking about Domain Adaptation which is quite an interesting topic on its own. Domain Adaptation with Structural Correspondence Learning by John Blitzer, Introduction to Domain Adaptation guest lecturer: Ming-Wei Chang CS 546,  and Word Segmentation of Informal Arabic with Domain Adaptation are fairly interesting readings. The lecture slides are heavily inspired by Introduction to Domain Adaptation guest lecturer: Ming-Wei Chang CS 546.

With sentiment analysis and opinion mining,  we went over the seminal Latest Semantic Analysis - LSIClustering Algorithm Based on Singular Value DecompositionLatent Semantic Indexing (LSI), (Deerwester et al. 1990), and Latent Dirichlet Allocation (LDA), (Blei et al. 2003). The class had an interesting discussion around the The Hathaway Effect: How Anne Gives Warren Buffett a Rise, with a potential NSFW graphic. The lecture can be summed up in Comprehensive Review of Opinion Summarization Kim, Hyun Duk; Ganesan, Kavita; Sondhi, Parikshit; Zhai, ChengXiang (PDF version).

Few other papers / research work and demos discussed during the lecture included Get out the vote: Determining support or opposition from Congressional floor-debate transcriptsMultiple Aspect Ranking using the Good Grief AlgorithmDistributional Footprints of Deceptive Product ReviewsRecursive Neural Tensor Network - Deeply Moving: Deep Learning for Sentiment Analysis,  Code for Deeply Moving: Deep Learning for Sentiment Analysis, and Sentiment Analysis - The Stanford NLP DemoStanford Sentiment Treebank.

Among several class discussions and exercises/quiz, The Distributional Footprints of Deceptive Product Reviews was of primary importance. Started with  Amazon Glitch Unmasks War Of Reviewers, darts were thrown around Opinion Spam Detection: Detecting Fake Reviews and Reviewers Fake Review Detection: Classification and Analysis of Real and Pseudo Reviews 

With all this sentiment analysis talks, I have asked fellow attendee Mohammed Al-Hamdan (Data Analyst at Al-Elm Information Security Company), about publishing a paper by the end of this course on sentiment analysis in Arabic language twitter feeds for potential political dissent. Would be a cool project / publication.

Looking forward to the session tomorrow!

Bonus, here is Dr. Regina Barzilay — Information Extraction for Social Media video - publicly available on youtube.

Deep Learning with Neural Networks

Deep learning architectures are built using multiple levels of non-linear aggregators, for instance neural nets with many hidden layers. In this introductory talk Will Stanton discusses the motivations and principles regarding learning algorithms for deep architectures. Bill provides a primer to neural networks, and deep Learning. He explains how Deep Learning gives some of the best-ever solutions to problems in computer vision, speech recognition, and natural language processing.

and also, why Google is Investing in deep learning.



Monads by David Crockford

The monadic curse is that once someone learns what monads are and how to use them, they lose the ability to explain it to other people.

Excellent lecture. Transcript and Monads for Humans


Microservices by Martin Fowler @ Goto Conference

An interesting portrayal of Microservices by Martin Fowler.


The term "Microservice Architecture" has sprung up over the last few years to describe a particular way of designing software applications as suites of independently deployable services. While there is no precise definition of this architectural style, there are certain common characteristics around organization around business capability, automated deployment, intelligence in the endpoints, and decentralized control of languages and data.
