QUESTION
I am trying to overwrite from the CLI a group of parameters and I am not sure how to do it. The structure of my conf is the following

QUESTION
Tensorflow text_classification:
https://www.tensorflow.org/tutorials/keras/text_classification
There are only two classes in this text_classification example,
...ANSWER
Answered 2022-Feb-23 at 07:54You should define a threshold that whenever you get a value greater than it it is considered as positive, otherwise it considers it as negative. In your example to get [1,1,0] a threshold of 0.4 for example gives the right predictions.
QUESTION
This is my code, the function work well for train set but for test set returns this error RuntimeError: Token second\team not found and default index is not set
ANSWER
Answered 2022-Jan-01 at 14:25The vocabulary acts as a lookup table for your data translating str
to int
. When a given string (in this case "second\team") doesn't appear in the vocabulary, there are two strategies to compensate:
- Throw an error because you don't know how to handle it. Imagine something like a
KeyError
when calling{}[1]
in Python - Assign a default "unknown" token to the missing tokens. Imagine a default value like
{}.get(1, "I don't know!")
in Python.
Your code is currently doing #1. You seem to want #2 which you can achieve using vocab.set_default_index
. When you build your vocab, add the specials=[""]
kwarg and then call vocab.set_default_index(vocab[''])
.
QUESTION
A text TextVectorization
layer is used for word encoding, and the typical workflow calls the adapt()
method
Next, you will call adapt to fit the state of the preprocessing layer to the dataset. This will cause the model to build an index of strings to integers.
(https://www.tensorflow.org/tutorials/keras/text_classification)
or
If desired, the user can call this layer's adapt() method on a dataset. When this layer is adapted, it will analyze the dataset, determine the frequency of individual string values, and create a 'vocabulary' from them.
(https://www.tensorflow.org/api_docs/python/tf/keras/layers/TextVectorization#adapt)
What is precisely the result of the adapt()
operation, and how to check concretely the content of the created vocabulary?
A small piece of my code

QUESTION
I'm trying to learn how to use some ML stuff for Android. I got the Text Classification demo working and seems to work fine. So then I tried creating my own model.
The code I used to create my own model was this:
...ANSWER
Answered 2021-May-27 at 15:50In your codes you trained a MobileBERT model, but saved to the path of average_word_vec? spec = model_spec.get('mobilebert_classifier') model.export(export_dir='average_word_vec')
One posssiblity is: you use the model of average_word_vec, but add MobileBERT metadata, thus the preprocessing doesn't match.
Could you follow the Model Maker tutorial and try again? https://colab.sandbox.google.com/github/tensorflow/tensorflow/blob/master/tensorflow/lite/g3doc/tutorials/model_maker_text_classification.ipynb Make sure change the export path.
QUESTION
I am trying to understand the TensorFlow
text classification example at https://www.tensorflow.org/tutorials/keras/text_classification. They define the model as follows:
ANSWER
Answered 2021-Apr-15 at 11:20This model uses a single activation function at the output (a sigmoid), used for predictions for a binary classification task.
The task to perform often guides the choice of both loss and activation functions. In this case, therefore, the Binary-Cross-Entropy loss function is used, as well as the sigmoid activation function (which is also called the logistic function, and outputs values between 0 and 1 for any real value taken as input). This is quite well explained in this post.
In contrast, you can also have multiple activation functions in a neural network, depending on its architecture; it is very common for instance in convolutional neural networks to have an activation function for each convolutional layer, as shown in this tutorial.

I'm working on a classification model based on the example, everything is working great, now I want to deploy this model as a REST service so that my applications can easily consume it.

QUESTION
I'm new to tensorflow2/keras. I was following this tutorial on tensorflow website. Instead of downloading the text data to directory, I use tensorflow_datasets
to load imdb dataset directly to tensors/numpy arrays. Below is my code.
ANSWER
Answered 2021-Feb-18 at 15:30Your dense layer is linear
which means you don't have any activation passed into it. There are several solutions, as you are doing binary_classification
.
If you want to use Dense(1)
as it is, then you should change loss function into:

I am trying to interact with my machine learning model where I can get the input value to the flask route method from HTML but not able to pass on the response with a string value to the ajax query.
THe click of the button hits the ajax function and does goto the flask route function, but it doesn't even hit the success or error part of the ajax function. Gives 405 Method not Allowed error. 127.0.0.1 - - [12/Oct/2020 13:15:17] "POST / HTTP/1.1" 405 -

QUESTION
I get some errors when I run the code in this tutorial. I want to predict on some test data. When I run the following it works:
...ANSWER
Answered 2020-Apr-13 at 20:52Short answer: Use test_data[0:1]
instead of test_data[0]
.
Long answer: The Keras/TF models works on batch of input samples. Therefore, when you give them only one input sample, it should still have a shape of (1, sample_shape)
. However, when you slice the test_data
array like test_data[0]
it would give you the first element with the first axis/dimension removed, i.e. with the shape of (sample_shape,)
(in this case (256,)
). To resolve this, use test_data[0:1]
in order to preserve the first axis/dimension (i.e. shape would be (1, 256)
).

Vulnerabilities
No vulnerabilities reported
Install text_classification
You can use text_classification like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
