kandi X-RAY | autonomio Summary
Autonomio provides a very high level abstraction layer for rapidly testing research ideas and instantly creating neural network based decision making models. Autonomio is built on top of Keras, using Tensorflow as a backend and spaCy for word vectorization. Autonomio brings deep learning and state-of-the-art linguistic processing accessible to anyone with basic computer skills. This document focus on an overview of Autonomio's capabilities.

QUESTION
For training my neural network model I use Keras' EarlyStopping
callback to minimize train time (via talos.utils.early_stopper
wrapper):
ANSWER
Answered 2021-Apr-03 at 16:14For some reason, changing monitor
from val_loss
to val_accuracy
(EarlyStopping(monitor="val_accuracy", min_delta=0.01, patience=2, verbose=1, mode='auto'
) seems to give a more consistent callback.
QUESTION
I want to learn about hyperparameter search in talos. Specifically the evaluation of the models. I was going through this example notebook https://nbviewer.jupyter.org/github/autonomio/talos/blob/master/examples/Hyperparameter%20Optimization%20with%20Keras%20for%20the%20Iris%20Prediction.ipynb#seven
No, my question is: In evaluation (7), how do I set a specific evaluation metric? E.g. F1 score for a classification problem. Do they come from Keras or talos? What is the default, if the parameter is not passed? I could not find it in the talos docs. Did I overlook sth?https://autonomio.github.io/docs_talos/#evaluate
...ANSWER
Answered 2019-Jan-29 at 15:15Evaluation in Talos use f1-score with binary average for binary classification, macro average for multi_label and multi_class, and MAE for regression. These come from sklearn.
The metric
argument refers to any metric you've already used in Scan()
experiment and is used for first picking the best model/s to evaluate. You can use any Keras or custom metric in Scan() as you would with your Keras models.
QUESTION
I want to tune hyper-parameters on keras
models and I was exploring the alternatives I had at hand. The first and most obvious one was to use scikit-learn
wrappers as shown here (https://keras.io/scikit-learn-api/) thereby being able to use all the faboulous things in the scikit-learn
worflow but I also came across this package here (https://github.com/autonomio/talos) that seems very promising and most likely offers a speed boost.
if anyone used them both, could someone point me towards the better solution (flexibility, speed, features)? The sklearn
workflow with pipeline
and custom estimators provides a world of flexibility but talos seems more directly geared towards keras specifically therefore it must yield some advantages (I guess they would not have made a new standalone package otherwise) which I am not able to see (some benefits are highlighted here https://github.com/autonomio/talos/blob/master/docs/roadmap.rst but such thigns seem to be adequately covered within the scikit-learn
framework)
any insights?
...ANSWER
Answered 2018-Jun-08 at 08:20Personal opinions:
train/valid/test split is a better choice than cross validation for deep learning. (The cost of k training is too high)
random search is a good way to start exploring the hyper-parameters, so it's not really hard to code this yourself but yes talos or hyperas (which is quite famous) could be helpfull.
