DECISION STATS

a few criteria that define a good data science project

• Learnability- What did you learn in the Project
• Capability – What capabilities were showcased in the project
• Difficulty- How difficult or easy was the project
• Potential Hireability- How likely are you going to be hired based on that project
• Ability- What creative approaches did you bring to the solution

 

A few datasets I liked only from a teaching purpose- iris, Boston, mtcars, Titanic, German Credit and mnist handwriting

A project is more than just a Kaggle dataset. hashtag#datascience hashtag#datasets hashtag#kaggle hashtag#machinelearning

In Seaborn a bar-chart can be created using the sns.countplot method and passing it the data

It is quite easy to create buckets based on one column using query. Note you can also use qcut

 

bucket1 =df.query(‘Column_1 >=0 and Column_1 <0.25’)

bucket2 =df.query(‘Column_1 >=0.25 and Column_1 <0.5’)

bucket3 =df.query(‘Column_1 >=0.5 and Column_1 <0.75’)

bucket4 =df.query(‘Column_1 >=0.75 and Column_1 <=1’)

spark= SparkSession.builder \
.master(“local”) \
.appName(“Data Exploration”) \
.getOrCreate()

#load data as Spark DataFrame
data2=spark.read.format(“csv”) \
.option(“header”,”true”) \
.option(“mode”,”DROPMALFORMED”) \
.load(‘/home/Desktop//input/*.csv’)
