From OpenCV and Tesseract to exploring recent research results in Computer Vision [Challenge 2]

challenges, Computer Vision, Deep Learning, learning, Technology

I've been away for a while... Actually, I didn't notice as the time was going on.. even though I felt like I've been running all days since my last article :D .. I was all in a new dimension of machine learning..one that is so huge and with many many possible doors to knock! -What is it that you called "new dimension"? Okay, let me tell you. If you followed my previous post about OpenCV and Tesseract, you may already know that I've been working on a computer vision project, involving Object Character Recognition (OCR) for texts in a natural scene image - By the way, I really like the problem that I'm trying to solve, that's why I accepted working on the project despite the fact that I don't have a previous…

Applied text classification on Email Spam Filtering [part 1]

My activities, projects, Technology

Since last few months, I've started working on online Machine Learning Specialization provided by the University of Washington. The first course was about ML foundations, the second about Linear Regression, and the third course on which I'm currently on track is about Classification. I liked the courses almost in every aspect as they teach ML algorithms implementation from Scratch. That was my goal when I decided to discover the field in more depth. But, honestly, I was feeling that there is a gap somehow because many questions were left without answers along the way. Then, after reading about how to start with Machine Learning, I found that most articles emphasized the importance of combining courses with practical projects in order to apply what's learned and better assimilate it.. and it's so true!…

Starting with OpenCV and Tesseract OCR on visual studio 2017 [Challenge 1]

challenges, Computer Vision, learning, projects

I have recently started working on a Freelance project where I need to use text scene recognition based on OpenCV and Tesseract as libraries. I was so motivated to hit the Wolrd of computer vision combined with machine learning and experience developing applications in the field, so I welcomed challenges that come with! Here I'll be talking about the first challenge and how I tackled it. found myself with multiple new things to prepare in order to start coding, without mentioning that it's been a long time before when I last coded with C++ (back to my university time)! At first, I was asked to use OpenCV 3.0 and Tesseract 3.02 in order to run the project's part which is already available. So I installed OpenCV 3.0 and Tesseract 3.02…

J On the Beach 2017

My activities, Technology

This time I made it to Malaga, Spain! I attended J on the Beach 2017 conference, a Big Data event targeting developers and DevOps communities. It was held over 3 days. The first day was about workshops. In the morning session, I participated in "Building Microservices on DS/OS" ensured by Jorg Schad where I got an idea about containers, Mesos, Clusters. It was a little bit difficult for me as all of them were new. [embed]https://twitter.com/MestiriSarah/status/864746342404456449[/embed] The Afternoon session was "Hands on Elastic Stack 5.3". The presenters Pablo Musa and David Pilato were very helpful and I liked so much combining discovering these tools with practice, as I believe that the best way to motivate people about learning something, is by showing results! I discovered how it's possible with Elasticsearch to get…

A glimpse into AI potential between today and tomorrow (part 1)

My activities, Technology

April 23rd, I was honored to be invited by GDG Monastir (Tunisia) as a speaker in Google Next 2017 extended event. My talk was about Artificial intelligence and following is the written version of the idea I wanted to communicate. I bet that when you think/hear about Artificial Intelligence many thoughts pop to your mind! Big Data, IBM Watson, Alexa, Google self-driving car, NAO, Turing, Google Cloud, but what’s Artificial Intelligence? Is it a brain that can outperform human’s brain? How does AI impact our everyday life? What are the technologies behind AI? What's AI? Back to 1950, when Alan Turing, a computer science pioneer, started thinking about “What if machines learn?”. He invented Turing Test in the aim of making an intelligent machine. The test was an adaptation of…

Is cracking the coding interview the only benefit of learning algorithms?

challenges, learning, My activities, Technology

Often, algorithms are considered only when someone is looking for a new job. This tight perception of algorithms use puts us away from what algorithms can allow us to achieve! Actually, algorithms are everywhere! Algorithms are involved in each aspect of computer science! Not only that but also used in a wide range of fields: recommendations, social media, medicine, psychology, transportation and the list is longer still! Anything you do, can be broken down into small steps and that, is an Algorithm. Imagine you wake up the morning to go to work and you can’t remember where are your car keys, how would you find them? One approach might be to apply an algorithm, which is a step by step logical procedure. First, you look for places where you used…

Up to my new tech challenges!

challenges, Technology

You have certainly heard about that unique thing, which changes your life and makes it magic, beautiful. It can be a person, a situation, a hardship, a moment of discovery.. so called "The Spark"! It all started three or four years ago when I discovered those intelligent features in my Smartphone "Samsung Galaxy S3": social tag, smart stay, smart alert and S voice. Many questions were coming to my mind about those features, I was so curious about what's behind their functionalities and how humans succeeded in developing such intelligent technologies! At that time, I was studying computer science engineering and wondering which option modules to take for the last semesters. So, I decided to study "decision making and artificial intelligent (AI) systems" as an option for my last two…

Data Natives Berlin 2016 day 2

My activities, Technology

Berlin, October 28th, Data Natives day 2. It was about tech trends, including numerous topics: Deep learning, Source code abstracts, analyzing and searching unstructured Medical Data, smart-data based lending, intelligent hiring, and more. Klaas Bollhoefer, Chief Data scientist at *um, tackled the gap between several departments in a traditional company and took the example of "operational gap" study, made for one of *um clients. He demonstrated how *um approached Metro Group issue: what does Metro need to do to become a leading analytics-driven omni-channel retailer. Among that, Klaas stated that "every company requires unique capabilities" in order to reach Data Maturity level and achieve digital transformation. For that, a bottom up approach should be done for analytics in order to explore the framing of any company. That means taking care of…

Data Natives Berlin 2016 Day 1

My activities, Technology

My journey in Berlin started with two days enjoying its winter landscape and counting days down to the conference for which I was determined to do the whole trip from my country, Tunisia in order to attend. Thursday, here it is! Data Natives opened its doors! I got up that same morning very excited to meet people sharing with me the passion for technology! I already discussed with some of them on twitter,like Lisa Winter and Evelyn Münster, so I was eager to get to know them. Looking at the schedule, it was difficult to choose which talks to join since all of them were interesting. There were subjects about Visualizing and Communicating High Dimensional Data, Clustering Data, Big Data Semantics, Connected things, and much more here. Besides, as Artificial Intelligence is a field…
