## Pills of ML & AI: Feature Selection

Did you know that there are basically three ways of selecting the most important features before feeding your database into an ML model?

## Predict house prices with dense neural networks and tensorflow

In a regression problem, we aim to predict the output of a continuous value, like a price or a probability. Contrast this with a classification problem, where we aim to select a class from a list of classes (for example, where a picture contains an apple or an orange, recognizing which fruit is in the picture).

## Discrete Probability Distributions

8 Discrete Probability Distributions¶ 8.2 Binomial Distribution¶ The following code plots the probability mass function (PMF) of \$B_{p,n}\$, the binomial distribution with parameters \$p\$ and \$n\$. It contains interactive sliders that you can use to vary \$n\$ over the interval \$[0,30]\$ and \$p\$ over the interval \$[0, 1]\$. In [1]: %matplotlib inline Let us now load the required code and analyze it part by part. In [2]: # %load plot_pmf.py import numpy

## CONSIDERATIONS WHEN DESIGNING VOICE-ASSISTED APPS

AI and assisted voice apps have become a new trend in almost every news media, social networks, professional meetups and forums. You probably have watched the movie “Her” a 2013 American romantic science-fiction drama film written, directed and produced by Spike Jonze. The film follows Theodore Twombly (Joaquin Phoenix), a man who develops a relationship with Samantha (Scarlett Johansson), an intelligent computer operating system personified through a female voice. The

## Recommender systems are confining us into a digital imprisonment.

Gone are the times when you needed to be a handyman to get search engines returning what you are searching for. In today’s digital era you dare to watch a movie on Netflix and the next thing you will see is a rain of suggestions of movies that really match your taste, pouring on your screen. Youtube has moved from being a collection of videos to a personalized basket of

## A Quick View on Higher order functions

In mathematics and computer science, a higher-order function (also functional, functional form or functor; not to be confused with the functor concept in category theory) is a function that does at least one of the following: takes one or more functions as arguments, returns a function as its result. In the untyped lambda calculus, Higher order functions assume that for T1,T2,T3 functions a map of (T1->T2)->T2 is equivalent to T1->(T2->T3).

## Three steps to make your website seductive to search engines

Very recently one of my clients asked me a question that many may find hilarious “Why all your apps look like they are in deep love with search engines?”. Ooh, well it is not hard but not easy as well to seduce search engines. However a careful programmer knows that there is no magic in optimising your sites with regards to search engines. Depending on the nature and the size

## Overlooked secret to develop durable software solutions

We usually hear and see stun people saying ” This guy really knows everything about IT, he can code in any language!!!”. may be such a guy can develop a durable software. really? To be able to code with a range of technologies such as java, php, nodejs, Ruby, Python, Objective C, C#, etc… can be really very good as long as you master most of them since this will

## Hadoop and its HDFS! another level for big data analytics

For almost 10 years I have been experimenting any new technology that has anything to do with data. from structured, semi-structured to unstructured data my real frustration was always when the data grew big and become almost in-exploitable. there is nothing embarrassing to a data scientist than when you have to admit that you do have the data but it will take years to get information from it. Thanks to
