Why companies prefer experience in Python over R in a data science interview?

Nearly 80% of the respondents in our ongoing survey say that recruiters prefer Python over R in a Data science interview.Ā What's been your experience?

Python is a language which is from the family of LISPS, and it the functional programming implementation of Python supports lambda calculus heavily. Also, the Machine Programming Language, also known as Caml is supported by Python itself.Python is a pure OOP, in the sense that programmers don't really create the objects, instead, the objects are manipulated directly. This allows the extension of Python with C very easy. In fact, all the objects of Python are built in C, or to some extent Java, but C programming is heavily used.Therefore, Python has not done it's tradeoff with speed and implementation. What we use in Python are wrappers of C functions ,which have been bundled as objects built in to the language. But, the PyObject takes care of the entire processing, therefore, programmers don't have to worry about the performance, and iwnstead can focus on the efficienty.This makes Python very robust for Data Science application, because the objects can be extended for various machine learning tasks, such as predictions and classification. The machine learning has various algorithms which are sequential in nature, and Python's data structures such as lists and tuples are also sequences, and they make a perfect blend. Similarly, the dictionaries can be used to map weights and the values together, and neural network algorithm can be written.

Will demand of data science jobs reduce in longer run?

There is a huge demand for data science jobs in short termĀ (<1-3 years) but I'm afraid that this demand may go down in longer run (>3 years). Reasons:I have observed that after the initial data modelling and implementation, there are no new projects in many companies. For routine improvements, companies may just need a fraction of data scientists they employ right now.Just like web development, ML and data science is seeing modularization and increasingly being packaged as a service (AWS and Google are marching ahead in this). This means there will be fewer data scientists needed to implement same projects in future than today.What do you folks think?

Sure,Ā the two factors you mentioned will likely hurt the demand. Many companies I see are currently hiring data scientists just because ofĀ FoMo ("Fear of Missing out"). This is "artificial" demand and will certainly go down once the reality sets in.But will this correction actually hurt data science professionals?I don't think so. InĀ next 3-5 years, I also see a huge demand getting created by mainstream companies that are yet to make a move in data science. Think about ICICI bank, Maruti, Air India, Tata group and then a ton of PSUs like Indian Oil and NABARD. Given their huge scale, they will need an army of data science professionals and that demand will be 1000x of what we are seeing today.Ā In sum, I think these are initial days of data science profession. The real boom is going to actually arrive in next 5 years and will continue for at least another 10.

Majority of Data Scientists come from a software background and Python automatically becomes a favorite for them. Moreover with features like generator; python can be faster than R.You may have a read at the below writeup, which articulates well on the pros and cons.https://www.kdnuggets.com/2015/05/r-vs-python-data-science.htmlI believe itā€™s the use case that defines the demand and need, both are equally powerful and confusing at the same time.

How to develop a Bot from scratch?

I just created a bot, all from scratch. I will provide a detailed explanation of the steps.Firstly you provide a user some mechanism to enter his input. That can be voice based or text based. There are various options available for voice recognition and synthesis. I usedĀ https://github.com/TalAter/annyangĀ for speech synthesis on web and I must say, it is highly intelligent.Then you send this transcript or user's input text to a AI/ML model which can extract meaningful keywords along with the intent from this input. You need to train the model with some sample user commands/intent. This model will then parse the text and provide you a structured form of the input. Ā I usedĀ https://api.aiĀ which also gives you options to integrate with various platforms.The structured form of the input received from the AI model can be used to query the data from any data store of your liking, e.g:- mongodb, elastic search etc. You can then display the results to the user as per requirement.Thats all you need to build a bot outta nowhere.

How to gather trending news on a topic ?

Let's say we have a community that is interested in a topic such as "marketing and growth" or "DevOps". Every day we want to discover trending news for this community. How to do this keeping the relevance high AND with minimal manual curation? Some options we have exploredUse a service like Discovery service from Watson. We tried it but didn't find it much relevant. Is there an alternative like Google news?Follow around 25 Twitter handles or a specific hashtag and analyze thee tweets. Apply some heuristics to check if they contain news and use engagement metrics to guage the quality. Rank all of them to find the winners. (Twitter's engagement may be more on "virality" than "quality")Subscibe to RSS feeds from various blogs (do they still exist?)What'd you try?Any other ideas would be welcome too.

I don't know how efficient the following approach would be , but you can scrape some 10-15 websites for articles. Then put up a rule based filter on content after preprocessing to identify relevant articles. You can automate the script to run every morning to give you list of relevant URLs . Ā If you gotta some time, you can build a semi supervised / unsupervised model to find relevant articles instead of rule based approach.

If you are writing for production (not for research purpose) then caffe 2 seems to be a good choice. Ā Caffe 2 and Tensorflow both use static graphs which can be optimized. Caffe 2 core written in C++ and build upon caffeĀ so Nvidia frameworks like (TensorRT and Jetson) also support it. They are great for deploying CNN into production.Ā

We certainly are moving towards AI everywhere but I do not support the fact that AI will replace humans, be in terms of jobs or skills. I believe AI will show humans the true meaning of being human. We are wasting a lot of human potential in doing repetitive jobs and AI will relieve us from this. Our skills will certainly evolve with AI backing us up.

Why is R such a popular data science tool?

I've seen a lot of people talking about R in general. What makes it stand out from everything else available in the market right now.

top comment

The most important reason I think is that it is free and open sourced. Universities usually used to go for the more mature statistical tools SPSS or STATA - student package or a cheaper version of some kind. Students would pay up a small price and so would the universities. But their preference shifted to R as it started becoming much more powerful in its own way, and flexible in comparison to the other 3.Now, by all means, toolkits like SAS are the market leaders when it comes to analysis. But think about it. Employers that learntĀ Data Science through R are inclined to think that if someone doesn't know R, they aren't really in it. It is sadly true inĀ most cases. So your hiring chances drop too. R definitely has a steep learning curve. Hence in the beginning years, you are bound to lose sight of doing the actual data analysis and are more focused on getting the syntax right, or getting the code to work, which is kind of a bad thing. Most large scale companies, where cost doesn't matter much,Ā stick to the other 3. That being said, R is still much more flexible and a programming language that gives it an upper hand in some ways. It's not just a statistical tool. It's a language. My knowledge on this is actually very limited, and this answer is based on an article I read, and I don't remember which though. My apologies.

Hadoop is an ecosystem of various components. Some of the components you may be interested to use from R could be SQL(Hive , Impala ,Spark SQL) or for datascience activities.Ā SQL : An example scenario could be where you need to pull data from the underlying File system , which in Hadoop is HDFS. One simple way is to use a thrift server which exposes the data like how any database would do.Ā DataScience tasks : You can use SparkR for building data pipeline like pulling data from multiple sources , cleaning the data , applying distribnuted Ml .All these tools are best used based on the problem you are trying to solve .Ā Thanks,Vishnu Subramanian

How confident are you about building AI algorithms that can predict user behaviour?`

A.I. is the new rage, companies are using it in creative ways. How likely are these algorithms going to scale?

top comment

A.I. can scale as large as the data can scale.Ā The way I think about AI is like this:Ā What is the data I as a human need to predict a particular user behaviour; lets take the example of buying a product..Ā  What do I need to guess:1. Need for the product (If you need/want or not) 2. Brand, Quality, Cost etc of the product 3. Persons budget or economic situation Given this information, i can make a pretty good guess if someone is going to buy or not. And if a human can predict, so can a ML model given this info.Ā Now the beauty(and a little creepy) part is that we have all this data. Let me explain: 1. The need for the product is inferred by: search queries, time you spent on looking at that product, if you added to cart or not etc., 2. The product properties are already there in the system; 3. Economic data is also available thanks to the telecom operators, (remember the lousy form you filled when you were taking a sim card?)Ā and things other data providers who identify you by linkedin etc.All of this data is available with almost all the E-Commerce companies sold by 3rd party data providers.So as long as the data required for the predictions exist, AI can scale.!Ā

as soon as the data increases you will surely face complexity in analyzing it and the current algorithms will hold no/less relevance. You didn't mention what kind of data you are working with but as far as I know if working in text analysis,video,image or audio there is data available in abundance to train the machine learning model. anyhow try building a model which is flexible , do some research on the type of data you are working on, read some research paper and see how the complexity changes and design the algo accordingly
