Time series forecasting has a wide range of applications: finance, retail, healthcare, IoT, etc. Recently deep learning models such as ESRNN or N-BEATS have proven to have state-of-the-art performance in these tasks. Nixtlats is a python library that we have developed to facilitate the use of these state-of-the-art models to data scientists and developers, so that they can use them in productive environments. Written in pytorch, its design is focused on usability and reproducibility of experiments. For this purpose, nixtlats has several modules:

Data: contains datasets of various time series competencies.
Models: includes state-of-the-art models.
Evaluation: has various loss functions and evaluation metrics.

Objective:

- To introduce attendees to the challenges of time series forecasting with deep learning.
- Commercial applications of time series forecasting.
- Describe nixtlats, their components and best practices for training and deploying state-of-the-art models in production.
- Reproduction of state-of-the-art results using nixtlats from the winning model of the M4 time series competition (ESRNN).

Certain patterns are innately hierarchical, like the underlying parse tree of a natural language sentence. A Recursive Neural Tensor Network (RNTN) is a powerful tool for deciphering and labelling these types of patterns.

Twitter: https://twitter.com/deeplearningtv

The RNTN was conceived by Richard Socher in order to address a key problem of current sentiment analysis techniques – double negatives being treated as negatives. Structurally, an RNTN is a binary tree with three nodes: a root and two leaves. The root and leaf nodes are not neurons, but instead they are groups of neurons – the more complicated the input data the more neurons are required. As expected, the root group connects to each leaf group, but the leaf groups do not share a connection with each other. Despite the simple structure of the net, an RNTN is capable of extracting deep, complex patterns out of a set of data.

An RNTN detects patterns through a recursive process. In a sentence-parsing application where the objective is to identify the grammatical elements in a sentence (like a noun phrase or a verb phrase, for example), the first and second words are initially converted into an ordered set of numbers known as a vector. The conversion method is highly technical, but the numerical values in the vector indicate how closely related the words are to each other compared to other words in the vocabulary.

Once the vectors for the first and second word are formed, they are fed into the left and right leaf groups respectively. The root group outputs, among other things, a vector representation of the current parse. The net then feeds this vector back into one of the leaf groups and, recursively, feeds different combinations of the remaining words into the other leaf group. It is through this process that the net is able to analyze every possible syntactic parse. If during the recursion the net runs out of input, the current parse is scored and compared to the previously discovered parses. The one with the highest score is considered to be the optimal parse or grammatical structure, and it is delivered as the final output.

After determining the optimal parse, the net backtracks to figure out the appropriate labels to apply to each substructure; in this case, substructures could be noun phrases, verb phrases, prepositional phrases, and so on.

RNTNs are used in Natural Language Processing for both sentiment analysis and syntactic parsing. They can also be used in scene parsing to identify different parts of an image.

Have you ever worked with data where the underlying patterns were hierarchical? Please comment and let us know what you learned.

This video covers the additional work and considerations you need to think about once you have a deep neural network that can classify your data. We need to consider that the trained network is usually part of a larger system and it needs to be incorporated into that design. We also want to have some amount of confidence that the model will work on unseen data and that it’s going to interact as expected with the other system components. Ultimately, we also want to deploy it onto a target device which requires certain performance characteristics.

H2O.ai is a software platform that offers a host of machine learning algorithms, as well as one deep net model. It also provides sophisticated data munging, an intuitive UI, and several built-in enhancements for handling data. However, the tools must be run on your own hardware.

Deep Learning TV on
Facebook: https://www.facebook.com/DeepLearningTV/
Twitter: https://twitter.com/deeplearningtv

H2O.ai was founded by SriSatish Ambati, Cliff Click, and Arno Candel. In addition to its only deep net – a vanilla MLP – the platform offers a variety of models like GLM, Distributed Random Forest, Naive Bayes, a K-Means clustering model, and a few others. H2O.ai can be linked to multiple data sources in order to train data loads.

The UI is highly intuitive, but you can also work with the tools through other apps like Tableau or Excel. These interfaces allow you to set up a deep net by configuring its hyper-parameters.

H2O.ai needs to be deployed and maintained on your own hardware, which may be a limiting factor. However, the platform comes with many performance enhancements like in-memory map-reduce, columnar compression, and distributed parallel processing. Depending on your hardware’s capabilities, training on big data sets could be completed in a reasonable amount of time. As an added note, it’s unclear whether or not GPU support is a built-in feature at this point in time.

Do you have any experience with the H2O.ai platform? Please comment and share your thoughts.
