How to work with input which is a combination of metadata+ vectorized text data + image pixel data to build a Regression Model (predict views)?

Question

There are 4 datasets (all in csv format), each has a uniqueID column by which each record can be identified. Image and text datasets are dense datasets.(need to be converted to ndarray).

Can someone suggest how to use all these 4 datasets for building a regression model?

This is how the datasets look,

Metadata having some input features and target variable(views)

uniqueID    ad_blocked embed  duration language hour views
     1        True     True    68        3      10   244
     2        False    True    90        1      15   63
     3        True     False   195       3      7    350

Vectorized title data - one entire row represents a title

uniqueID  title_1   title_2    title_3 
     1   -0.977637  -0.543310  0.079403
     2    0.041873   0.644655  -0.406487        
     3    0.503560  -0.085412  0.841144

Vectorized descriptions data - one entire row represents a description

 uniqueID  title_1   title_2    title_3 
     1   -0.052256  -0.016036  0.079403
     2    0.000106  0.356706  -0.025788
     3    0.015774 -0.085412   0.712229

Thumbnail pixel data - one entire row represents an image

uniqueID  image_1    image_2   image_3
     1   -0.484456  -0.543310  0.032915
     2    0.666147  0.644655  -0.005733
     3    0.035018  -0.011111  0.841144

Answer 1

If we avoid a Neural Network,

• You should reduce the dimensionality of images e.g. PCA [ Assuming no translational variance among images]
• Can try the same for the other two datasets with 50 features
• Then try the ML models

If that doesn't work, we may try CNN for the image data.
In that scenario, we will need a mixed architecture of simple Neural Network and CNN.
