If you're reading this, you're probably looking to break into data science. I just want to start by informing you that data science in the wild is a different beast to the data science that you might be familiar with from your degree or online course. As a practitioner, I'd like to let you in on a few trade secrets I wish I had known before starting. I've learned the hard way and I'm graciously dropping these pearls so you don't have to mess up like I have done. Thank me by subscribing (if you want) …please.

Audiovisual scenes are pervasive in our daily life. It is commonplace for humans to discriminatively localize different sounding objects but quite challenging for machines to achieve class-aware sounding objects localization without category annotations, i.e., localizing the sounding object and recognizing its category. To address this problem, we propose a two-stage step-by-step learning framework to localize and recognize sounding objects in complex audiovisual scenarios using only the correspondence between audio and vision. First, we propose to determine the sounding area via coarse-grained audiovisual correspondence in the single source cases. Then visual features in the sounding area are leveraged as candidate object representations to establish a category-representation object dictionary for expressive visual character extraction. We generate class-aware object localization maps in cocktail-party scenarios and use audiovisual correspondence to suppress silent areas by referring to this dictionary. Finally, we employ category-level audiovisual consistency as the supervision to achieve fine-grained audio and sounding object distribution alignment. Experiments on both realistic and synthesized videos show that our model is superior in localizing and recognizing objects as well as filtering out silent ones. We also transfer the learned audiovisual network into the unsupervised object detection task, obtaining reasonable performance.

Building AI agents can be costly. Consider a question answering agent such as Jill Watson that automatically answers students' questions on the discussion forums of online classes based on their syllabi and other course materials. Training a Jill on the syllabus of a new online class can take a hundred hours or more. Machine teaching - interactive teaching of an AI agent using synthetic data sets - can reduce the training time because it combines the advantages of knowledge-based AI, machine learning using large data sets, and interactive human-in-loop training. We describe Agent Smith, an interactive machine teaching agent that reduces the time taken to train a Jill for a new online class by an order of magnitude.

We propose neural-symbolic integration for abstract concept explanation and interactive learning. Neural-symbolic integration and explanation allow users and domain-experts to learn about the data-driven decision making process of large neural models. The models are queried using a symbolic logic language. Interaction with the user then confirms or rejects a revision of the neural model using logic-based constraints that can be distilled into the model architecture. The approach is illustrated using the Logic Tensor Network framework alongside Concept Activation Vectors and applied to a Convolutional Neural Network.

This paper offers a comprehensive review of the research on Natural Language Generation (NLG) over the past two decades, especially in relation to data-to-text generation and text-to-text generation deep learning methods, as well as new applications of NLG technology. This survey aims to (a) give the latest synthesis of deep learning research on the NLG core tasks, as well as the architectures adopted in the field; (b) detail meticulously and comprehensively various NLG tasks and datasets, and draw attention to the challenges in NLG evaluation, focusing on different evaluation methods and their relationships; (c) highlight some future emphasis and relatively recent research issues that arise due to the increasing synergy between NLG and other artificial intelligence areas, such as computer vision, text and computational creativity.

The graph represents a network of 1,177 Twitter users whose tweets in the requested range contained "datascientist", or who were replied to or mentioned in those tweets. The network was obtained from the NodeXL Graph Server on Monday, 20 December 2021 at 20:06 UTC. The requested start date was Monday, 20 December 2021 at 01:01 UTC and the maximum number of days (going backward) was 14. The maximum number of tweets collected was 7,500. The tweets in the network were tweeted over the 3-day, 9-hour, 42-minute period from Thursday, 16 December 2021 at 15:18 UTC to Monday, 20 December 2021 at 01:00 UTC.

The field of machine learning is a vast topic and it can be hard to know where to start. In this blog post, we'll cover the top three free tutorial videos on machine learning from YouTube published this week (Week of Nov 1, 2021). These videos will help you get started with the basics of machine learning & deep learning, introduce you to some popular algorithms in use today, and give you an idea of what's possible when building a model from scratch. Let's say you want to build a machine learning project from scratch. Maybe you're not sure how to get started, or maybe you just need a refresher on the basics of data science and machine learning before diving into something more advanced.

Starting from the mid/late 1980's, many aspiring musicians (like me…) used the legendary Commodore Amiga computer to learn and compose music. Amiga's sound and graphics capabilities were pretty incredible compared to other home computers available at the time, and it quickly became popular among gamers, coders, graphic artists and musicians all over the world, and especially in Europe. Many Amiga musicians used a tracker, a type of music software that produces modules, or mods for short. A mod is a single file that contains everything necessary to play back a full song: notation, arrangement, song structure and instruments. As you might have guessed, trackers and mods were quite primitive by today's standards.
