The Fifth Elephant Winter edition starts at 9:30 am; live stream for members This update is for participants only
##The eighth edition of The Fifth Elephant will be held in Bangalore on 25 and 26 July. A thousand data scientists, ML engineers, data engineers and analysts will gather at the NIMHANS Convention Centre in Bangalore to discuss:
- Model management, including data cleaning, instrumentation and productionizing data science.
- Bad data and case studies of failure in building data products.
- Identifying and handling fraud + data security at scale
- Applications of data science in agriculture, media and marketing, supply chain, geo-location, SaaS and e-commerce.
- Feature engineering and ML platforms.
- What it takes to create data-driven cultures in organizations of different scales.
1. Meet Peter Wang, co-founder of Anaconda Inc, and learn about why data privacy is the first step towards robust data management; the journey of building Anaconda; and Anaconda in enterprise.
2. Talk to the Fulfillment and Supply Group (FSG) team from Flipkart, and learn about their work with platform engineering where ground truths are the source of data.
3. Attend tutorials on Deep Learning with RedisAI; TransmorgifyAI, Salesforce’s open source AutoML.
4. Discuss interesting problems to solve with data science in agriculture, SaaS perspective on multi-tenancy in Machine Learning (with the Freshworks team), bias in intent classification and recommendations.
5. Meet data science, data engineering and product teams from sponsoring companies to understand how they are handling data and leveraging intelligence from data to solve interesting problems.
##Why you should attend?

Exploring the un-conventional: End to End learning architectures for automatic speech recognition
Session type: Lecture Session type: Full talk of 40 mins
Speech recognition is a challenging area, where accuracies have risen dramatically with the use of deep learning over the last decade, but there are still many areas of improvement. We start with the basics of speech recognition and the design of a conventional speech recognition system, comprising of acoustic modeling, language modeling, lexicon (pronunciation model) and decoder. To improve the accuracy of speech recognition and to reduce the size of the model (especially for edge computing based On-device speech recognition), new architectures are emerging. In a conventional speech recognition system, the acoustic and language model are trained separately, on different datasets. With End-to-End ASR, we can develop a single neural network which jointly learns the acoustic model, lexicon and language model components together. E2E ASR can potentially help reduce the model size by up to 18 times and also improve the accuracy (word error rate) by up to 15 %. This is based on the Listen-Attend-Spell end-to-end architecture, augmented with CTC loss, label smoothing and scheduled sampling techniques. This architecture results in increasing accuracy and reducing model size by up to 18 times with no out of vocabulary words. We can get multi-lingual and multi-dialect models with are simpler and smaller in size. A few shortcomings are the lack of streaming (online) speech recognition and handling of rare or proper nouns which can be solved by techniques such as contextual Listen-Attend-Spell, Language Model Fusion, Online attention to support real-time streaming output, personalization/biasing through a context encoder, and adaptation based on auxiliary network / multi-task learning. We go into the motivation and approach behind each of these techniques, which may also be applicable to other deep learning based systems.
We challenge the status quo in automatic speech recognition technology to achieve breakthrough results using end to end speech recognition. The talk summarizes the latest research in this area.
