            How do I make a condition to execute a command once an element of numPy array achieves a certain value?
            Asked 2021-Jun-10 at 17:11

            I'm creating a machine-learning program to recognize images that are shown on webcam. I've used Google Teachable Machine to generate the model and it works fine.

            The matter I'm having issues with is printing the results of a prediction array, when an element of this array achieves a certain value (if it's equal to or more than 0.9 for an element, print a specific message).

            Let's say when element prediction[0] >= 0.9 I want to execute print("Up") as it recognizes the image of an arrow facing up or if element prediction[1] >= 0.9 I'd do a print("Down") etc.

            How can I access the best neural network model identifed through RandomizedSearchCV

            I am looking to extract and use (within the same Jupyter notebook) the model identified as the best model from RandomizedSearchCV for future fitting and graphing. Specifically, I am looking to re-fit the Keras Neural Network identified as the best so that I can plot the loss and accuracy against the same or other dataset.

            If I run the following code, I get the output I expect - the best score and the paramaters used in obtaining that score.

            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:

            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

            Difference between Tensorfloat and ImageFeatureValue
            Asked 2021-May-31 at 01:44

            When using the Windows-Machine-Learning library, the input and output to the onnx models is often either TensorFloat or ImageFeatureValue format.

            My question: What is the difference between these? It seems like I am able to change the form of the input in the automatically created model.cs file after onnx import (for body pose detection) from TensorFloat to ImageFeatureValue and the code still runs. This makes it e.g. easier to work with videoframes, since I can then create my input via ImageFeatureValue.CreateFromVideoFrame(frame). Is there a reason why this might lead to problems and what are the differences between these when using videoframes as input, I don't see it from the documentation? Or why does the model.cs script create a TensorFloat instead of an ImageFeatureValue in the first place anyway if the input is a videoframe?

            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].

            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,
