Interpolation is a technique in Python used to estimate unknown data points between two known data points. Interpolation is mostly used to impute missing values in the dataframe or series while preprocessing data.

```
import numpy as np
from scipy.interpolate import interp1d
# generate some example data
W = 3
H = 10
M = 5
A2 = np.arange(W * M).reshape(W, M)
print(A2)
# [[ 0 1 2 3 4]
# [ 5 6 7 8 9]
# [10 11 12 13 14]]
# the initial column indices for A2
x = np.arange(M)
# we create a scipy.interpolate.interp1d instance
itp_A2 = interp1d(x, A2, kind='nearest')
# the output column coordinates for A1
xi = np.linspace(0, M - 1, H)
# we get the interpolated output by calling the interp1d instance with the
# output coordinates
A1 = itp_A2(xi)
print(A1)
# [[ 0. 0. 1. 1. 2. 2. 3. 3. 4. 4.]
# [ 5. 5. 6. 6. 7. 7. 8. 8. 9. 9.]
# [ 10. 10. 11. 11. 12. 12. 13. 13. 14. 14.]]

Interpolation is a method of estimating unknown data points in a given dataset range. Discovering new values between two data points makes the curve smoother. Spline interpolation is a type of piecewise polynomial interpolation method.

Know the formula for the linear interpolation process. The formula is y = y1 + ((x – x1) / (x2 – x1)) * (y2 – y1), where x is the known value, y is the unknown value, x1 and y1 are the coordinates that are below the known x value, and x2 and y2 are the coordinates that are above the x value.

interp() function returns the one-dimensional piecewise linear interpolant to a function with given discrete data points (xp, fp), evaluated at x. Parameters : x : [array_like] The x-coordinates at which to evaluate the interpolated values.

I just learned that you can handle missing data/ NaN with imputation and interpolation, what i just found is interpolation is a type of estimation, a method of constructing new data points within the range of a discrete set of known data points while imputation is replacing the missing data of the mean of the column.

How to interpolate

- Organize your data. First, put the data you've collected into a chart that shows your independent and dependent variables.
- Consider creating a graph.
- Select your two points.
- Enter values into the interpolation equation.
- Solve for the missing variable.

Resample and Interpolate time series data

- import pandas as pd df = pd.read_csv('./datatest.txt') df1 = pd.read_csv('./datatest_next.txt') df2 = pd.concat([df,df1]) df2[ 'date' ] = pd.to_datetime(df2['date'])
- # Resample Hourly df3 = df2.set_index('date').resample('H').mean() df3.

Know the formula for the linear interpolation process. The formula is y = y1 + ((x - x1) / (x2 - x1)) * (y2 - y1), where x is the known value, y is the unknown value, x1 and y1 are the coordinates that are below the known x value, and x2 and y2 are the coordinates that are above the x value.
