grid_result.best_estimator_ contains the refit estimator (since you've left the default value for the refit parameter), which is a fitted clone of your clf. That happens to be a pipeline object (with two steps) in your case; if you want to access the keras model, you can access it as though a dictionary:

grid_result.best_estimator_['model'] will be a fitted KerasClassifier object. And those have the model attribute which contains the native keras object:

grid_result.best_estimator_['model'].model

When creating a tensor that will be used in conjuction with a model input feature that is defined with free dimensions (ie: "unk_518"), you need to specify the actual concrete dimension of the tensor.

In your case it looks like you are using SqeezeNet. The first parameter of SqueezeNet corresponds to the batch dimension of the input and so refers to the number of images you wish to bind and run inference on.

Replace the "unk_518" with the batch size that you wish to run inference on:

Perhaps you can try with regex in JS.

As stated here, nested parameters must be accessed by the __ (double underscore) syntax. Depending on the depth of the parameter you want to access, this applies recursively. The parameter use_idf is under:

features > text_features > tfidf > use_idf

So the resulting parameter in your grid needs to be:

Found the answer here.

If Windows ML does not support your model's color format or pixel range, then you can implement conversions and tensorization. You'll create an NCHW four-dimensional tensor for 32-bit floats for your input value. See the Custom Tensorization Sample for an example of how to do this.

.values is only returning the values of the data frame with the axis labels removed.

.iloc uses integer-location based indexing.

The .iloc portion of code is saying that we need the first 100 rows of only column 0 and 1 for our independent variable and only the first 100 rows of row 4 for our dependent variable. If this part is still confusing, I recommend that you look into slice notation. Quickly put, the slice notation on the .iloc simplifys to .iloc[start:stop].

Original DataFrame:

Just as the official docs for tf.keras.Sequential suggest, no batch_size needs to be provided when inputs are instances of tf.data.Dataset while calling tf.keras.Sequential.fit(),

Integer or None. Number of samples per gradient update. If unspecified, batch_size will default to 32. Do not specify the batch_size if your data is in the form of datasets, generators, or keras.utils.Sequence instances (since they generate batches).

In case of tf.data.Dataset, the fit() method expects a batched dataset.

To batch the tf.data.Dataset, use the batch() method,

• I don't know why, but using subplots=True with numeric column names seems to be causing the issue.
• The resolution is to convert the column names to strings
