Day 2 Inquiry on Courses, Intro to R and Master's in Data Science

Checked online certain universities for Data Analysis or Data Sciences or Machine Learning or Computational Sciences courses. It isn't so widespread in UAE , sent some mails and inquired with some recently LinkedIn contacts.

Check this link for lot of good information on the path

Now on the learning R , seems cool esp. the vector factor , slowly I correlate similar data (eg. nos) and then classifying the similar data on a pattern (eg. days) and doing certain analysis on them to extract information.
I have taken this course. https://campus.datacamp.com/courses/free-introduction-to-r

What About Certifications?

To avoid wasting time on poor quality certifications, ask your mentors for advice, check job listing requirements and consult articles like Tom’s IT Pro “Best Of” certification lists. Here are a few that focus on useful skills:

Certified Analytics Professional (CAP)

CAP was created in 2013 by the Institute for Operations Research and the Management Sciences (INFORMS) and is targeted towards data scientists. During the certification exam, candidates must demonstrate their expertise of the end-to-end analytics process. This includes the framing of business and analytics problems, data and methodology, model building, deployment and life cycle management.

Requirements:

5+ years of analytics work-related experience for BA/BS holder in a related area
3+ years of analytics work-related experience for MA/MS (or higher) holder in a related area
7+ years of analytics work-related experience for BA/BS (or higher) holder in an unrelated area
Verification of soft skills/provision of business value by employer
Agreement to adhere to Code of Ethics

Cloudera Certified Professional: Data Scientist (CCP:DS)

Targeted towards the elite level, the CCP:DS is aimed at data scientists who can demonstrate advanced skills in working with big data. Candidates are drilled in 3 exams – Descriptive and Inferential Statistics, Unsupervised Machine Learning and Supervised Machine Learning – and must prove their chops by designing and developing a production-ready data science solution under real-world conditions.

~~Related Cloudera certifications include:~~

~~Hadoop Developer (CCDH)~~
Hadoop Admin (CCAH)
~~HBase Specialist (CCSHB)~~

EMC: Data Science Associate (EMCDSA)

The EMCDSA certification tests your ability to apply common techniques and tools required for big data analytics. Candidates are judged on their technical expertise (e.g. employing open source tools such as “R”, Hadoop, and Postgres, etc.) and their business acumen (e.g. telling a compelling story with the data to drive business action).

Once you’ve passed the EMCDSA, you can consider the Advanced Analytics Specialty. This works on developing new skills in areas such as Hadoop (and Pig, Hive, HBase), Social Network Analysis, Natural Language Processing, data visualization methods and more.

SAS Certified Predictive Modeler using SAS Enterprise Miner 7

This certification is designed for SAS Enterprise Miner users who perform predictive analytics. Candidates must have a deep, practical understanding of the functionalities for predictive modeling available in SAS Enterprise Miner 7 before they can take the performance-based exam. This exam includes topics such as data preparation, predictive models, model assessment and scoring and implementation.

Related SAS certifications include:

Day 20 Google APIs, Google Application Default Credentials

Searching for objects attribute value, it has to be Datastore . Remember that BigTable, you can only search by key. High-throughput writes of wide-column data. Well, that is BigTable , right, because it's supporting high-throughput writes. Warehousing structured data. So what's the data warehouse technology on Google Cloud? That's, which one, BigQuery . To create and test new machine learning methods. Well, if you're writing new machine learning methods, then TensorFlow . Develop Big Data algorithms interactively in Python.Well, interactive development in Python is done best with Datalab . Well, interactive No-ops, custom machine learning applications at scale. No-ops ML at scale, then that's a role for Cloud ML. Automatically reject inappropriate image content. Rejecting image content where it is inappropriate. Well, that could be the Vision API. So you could use a Vision API to basically see if this is safe content or not safe content.

Day 8 - Microsoft AI | Arduino Robotic Kit

Arduino Robotic Kit https://photos.app.goo.gl/Ng6MmaRnxHHWUHpJ6 Just got my Arduino robotic kit , quite excited :-) , Let us start exploring the various components. HC SR 04 Ultrasonic Ranging Module https://www.mouser.com/ds/2/813/HCSR04-1022824.pdf HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm Vcc , Trigger , Echo n Ground You only need to supply a short 10uS pulse to the trigger input to start the ranging, and then the module will send out an 8 cycle burst of ultrasound at 40 kHz and raise its echo. The Echo is a distance object that is pulse width and the range in proportion https://randomnerdtutorials.com/complete-guide-for-ultrasonic-sensor-hc-sr04/ https://www.arduino.cc/en/Reference/Libraries https://www.youtube.com/watch?v=6F1B_N6LuKw

Helplessness

So we had no project and to add the to misery no jobs.We were told by our placement dept tht our dept so called MEDICAL ELECTRONICS wasn't allowed by most of the companies. We all wer dejected as all of us had worked hard and wanted to get some job.I tht why sit n crib all time when u have so much time to enjoy. So i hit wit my family to Rajasthan.It was a nice but extremely hectic trip for me. We went by flight to jaipur then next day jodhpur by bus the same day udaipur by bus ,whr i came to know tht companies wer allowing us n the placement dept scammed us. So next day we left frm udaipur to mumbai by train n then the same day to bangalore by bus. In 5 days i had spanned across 5 states. I rechd bangalore and had accenture next day so went thro the placement bible RS Aggarwal. Sadly i didn't clear then i sat for HCL which again i didn't clear so i was amidst doubt within myself. But still i didn't lose hope n worked harder.
