Hit Song Prediction

Can you predict the success of a song, just by listening to it? I know! at least we try to do it many times, and a lot of times our predictions do turn out to be true. While we do consider many things and most importantly the emotions involved. Can we expect a deep learning model to predict that!?.

Of course! In this article, we will figure out how though.

IMPORTING LIBRARIES AND DATASET

We will start with importing the necessary libraries and the dataset. For my model, I am using the dataset containing 90’s songs, though I’ll link datasets for different periods. All these songs in these datasets are taken from Spotify.

After importing all the necessary stuff we will first check if our dataset is balanced or not. A balanced dataset is one that contains equal or near to equal value count for different classes of the prediction feature. Our dataset is already balanced!!

PREPROCESSING

Now, our dataset does contain some irrelevant features (which are not much of use to us for model building), hence we will drop “track”,” artist”,”uri”.

For further preprocessing, we will also scale our data. I am using sklearn’s preprocessing.scale for this purpose.

Now, we will be diving our dataset into train, validation, and test. I am also saving all three of them for an easy and smooth process.

MODEL

Now I’ll be moving onto the model, I have used a Sequential model.

The structure of our sequential model looks like this:

MODEL

and for compilation of the model, I have used: optimizer =”adam”, loss =”binary_crossentropy”, and metrics = [“accuracy”].

LOSS FUNCTIONS
ACTIVATION FUNCTIONS

You can refer to these two videos for a better understanding of loss and activation functions.

ANALYSIS

I have trained my model on 20 epochs, You can really, play around with this for better accuracy or even less loss. In my case, I got 86.14% training accuracy and 84.78% validation accuracy using above mentioned parameters. That’s pretty cool no!

After training and saving the model, it is a good practice to visualize the results of our model. I have attached the model accuracy and model loss graph you can have a look at.

LOSS
ACCURACY

PREDICTION

Now, it’s prediction time! For our case predicted value, 1 indicates a song will be a hit, hence 0 indicates otherwise. I have used a very basic logic in my code to print them as Hit and Not a Hit you can check that out too.

Finally, do not forget to evaluate the performance of your very own model.

I’m Sorry! Evernote Has A New ‘Home’ Now

Original Source Here My Apologies! I was critical about the grandfather of all apps — Evernote a few months back when I wrote Why is Evernote losing its Ground? on Medium. With that said, I also wrote another story on Evernote in November of last year — Has Evernote Made A Comeback After Years Of Stagnation? This was the time when Ian Small and his team were making inroads into the technology and strategically making enhancements and revamping the app across all platforms. Evernote Is At A War-front And Wants To Prove A Point. I must h ave written this in my earlier blogs but just to re-iterate — I have been and am an avid user of Evernote since 2009 and is a part of my life for planning my daily life, projects, content writing, and almost everything. Recently, Evernote has launched its HOME or you may call it a DASHBOARD that provides its users a one-stop place to get access to their important and critical notes and also provides a few AI-enabled capabilities that I wil

Jensen Huang , CEO of Nvidia , received the distinguished lifetime achievement award by the Asian American Engineer of the Year from the Chinese Institute of Engineers (CIE) group. And in his acceptance speech, he made a rare comment beyond Nvidia’s business matters: “Racism is one flywheel we must stop.” The comments came at the end of an acceptance speech where he thanked the group for its award, an annual gathering that recognizes outstanding Asian American scientists, engineers and role models. In a virtual ceremony, Huang was awarded for his contributions as “a visionary and innovator in parallel computing technology that accelerates the realization of AI computing.” He also spoke of his experience as an immigrant and an Asian American. “It is strange to accept a lifetime achievement

5 Best Machine Learning Books for ML Beginners

Original Source Here Reading books is important because they books you endless knowledge. If you plan to become a Data Scientist or Machine Learning Engineer, reading machine learning books will help you gain the knowledge and skills required in this field. In a simple definition, machine learning is known as the subset of AI that has the ability to automatically learn from the data without explicitly being programmed or assisted by domain expertise. Email spam and malware filtering, product recommendations, image recognition, automatic language translation — these are all examples of real-life machine learning applications. The Futu r e of Jobs Report 2020 predicts that artificial intelligence (of which machine learning is a subset) will create 12 million new jobs across 26 countries by 2025. There are many books available in the market to learn machine learning. In this article, I have compiled the 5 best machine learning books that will help you start building your care
