How data enables ML?
Using an ex.
input bank of pictures and output of labeled pictures of 1000 categories. Task: get the MLM to learn what pics go to what outputs.
Model tunes the own parameters to the dataset. Model turns into its own approximations. Parameters are the rules. Neural Network (model) and Weights(rules)

pd.date_range(‘2019-01-01’ , periods=3, freq=’H’)
What does this mean?
pd.date_range(‘2019-01-01’ , periods=3, freq=’H’)
H - Hourly
3 - Means we want 3 periods
2019-01-01 is the date range the computer recognized
pd.date_range(‘2019-01-01’, periods=3, freq=’H’, tz_localize(‘UTC’)
What does this mean?
H = hourly
2019-01-01 = Date range starts
Periods = We want 3 periods
UTC = Time Zone
pd.date_range(‘2019-01-01’, periods=3, freq=’H’, tz_localize(‘UTC’) .tz_convert(‘US/Pacific’)
What does this mean?
H = hourly
2019-01-01 = Date range starts
Periods = We want 3 periods
Changed the time from UTC to US Pacific
