7 must-have traits for a successful data team

#artificialintelligence

So I want to lay out some of the skills that business leaders should be looking for when they hire data professionals today--whether they be data analysts, data engineers, data product managers, or data scientists. If an analyst's idea of presenting findings to business stakeholders is saying "We found a strong negative correlation--R 2 0.53. Too many data science training programs focus intensely on teaching the algorithms that data scientists use, using pristine datasets that are never found in the real world. They ignore the fact that most of a data scientist's time is actually spent finding, cleaning, and reshaping raw data to make it ready for modeling.


The tips and tricks I used to succeed on Kaggle

#artificialintelligence

I learned machine learning through competing in Kaggle competitions. In my first ever Kaggle competition, the Photo Quality Prediction competition, I ended up in 50th place, and had no idea what the top competitors had done differently from me. What changed the result from the Photo Quality competition to the Algorithmic Trading competition was learning and persistence. Because feature engineering is very problem-specific domain knowledge helps a lot.

How to hire a great Data Scientist - Saikat Sarkar, Data Science Exper

#artificialintelligence

He is presently acting as the Subject Matter Expert of Python in Aegis School of Data Science. He also talks about the importance of the Data Science domain today and in the years to come. Typically, a company should look at candidates with fairly strong programming skills and statistical understanding of ML. Modern day ML concepts are not known by the senior people of the organisation, they have worked on old school statistics, so that's the field they try to drill the candidates in.


Analyzing Oscar Data

@machinelearnbot

She graduated from the NYC Data Science Academy 12 week full time Data Science Bootcamp program taking place between April 11th to July 1st, 2016. Exploring the distribution of the MPAA Ratings we see PG 13 films have the highest box office receipts, followed by General Audience films, then PG and final rated R films. We see on the contrary those films rated R, have won the most Academy Awards, where films rated G for general audience have not won any Oscars in this dataset. I fit a logistic regression and received a significant coefficients for Box office tickets, IMDb Rating, Rank in Year, Romance, Drama, Adventure, Western.


Quantum Computing and Deep Learning. How Soon? How Fast?

@machinelearnbot

Add to that the new IBM Q program offering commercial quantum compute time via API where IBM says "To date users have run more than 300,000 quantum experiments on the IBM Cloud". In 2010 Lockheed became D-Wave's first commercial customer after testing whether (now 7 year old) Quantum computers could spot errors in complex code. Temporal Defense Systems (TDS): TDS is using the latest D-Wave 2000Q to build its advanced cyber security system, the Quantum Security Model. Commonwealth recently announced a large investment in a Quantum simulator, while Westpac and Telstra have made sizable ownership investments in Quantum computing companies focused on cyber security.


Deep learning & XgBoost : Winning it hands down !

@machinelearnbot

A one-liner R code running a deep learning algorithm with 3 hidden layers each having 1024,1024,2048 neurons respectively, the non-linear differentiable activation function being rectifier with dropout; achieved an error rate of 0.83 % on the test data! If are not feeling lazy, you gotta do some hyper parameter tuning. Train the model on the tuned hyper parameters that gave the best accuracy as per the cross validation. Wait, You could even try Optunity to optimize the hyper parameter tuning and achieve even better results with xgboost model.

ai.bythebay.io: Vitaly Gordon, Machine Learning, The Right Way

#artificialintelligence

Getting started with data science and Machine Learning is a chicken and egg thing. Do I have enough data to even do data science? Vitaly Gordon, VP of Engineering and Data Science at Salesforce Einstein, will give you the tips you need to get a right start with the right people - at the right time. He will discuss Machine Learning technology but also tell you what data you need, and what business use cases you should start with.


How chatbots are changing customer service dynamics in banking

#artificialintelligence

Machine learning, may be the way to create chatbots that can interact with customers without controlling the conversation, learn from experience, and anticipate needs. These chatbots would either divert questions to a human operator and'watch' the human response, learning from it for next time, or be taught by human operators based on selected real interactions. All these issues add up to data scientists being essential in building deep learning algorithms and creating better banking chatbots. Data scientists support chatbots by supplying suitable sources of information, and making sure that the bot is calling on useful data.
