Half machine, half artist – meet DALL-E 2


In April, the artificial intelligence company OpenAI released its latest creation, DALL-E 2, a mind-bending piece of AI software that can turn text descriptions (captions) into photorealistic images.


DALL-E 2 (a mishmash of WALL-E and Dali) builds on the success of its predecessor DALL-E, which OpenAI unveiled in early 2021, and improves the quality and resolution of the output images thanks to advanced deep learning techniques.

Generating realistic images isn’t new to AI. What sets DALL-E and DALL-E 2 apart is they can generate them from natural language prompts of varying complexity.

While that may sound straightforward, it’s actually incredibly difficult for a machine learning algorithm to pick up on the subtleties of natural language instructions (or we’d all be programming computers in plain English), and create beautiful images with them.

What makes DALL-E 2 revolutionary is the incredible quality of the images it churns out. Take a look.

“A fire hydrant in the Sahara desert.”

“An oversized grizzly bear delivering a pizza”

OpenAI

“Mosaic of a bad ancient Roman cat being chased by an angry ancient Roman woman.”

OpenAI

“Macro 35mm film photography of a large family of mice wearing hats cosy by the fireplace.”

OpenAI

Unlike its predecessor, DALL-E 2 can also edit images, changing their composition, shadows, reflections, and textures through a process called ‘inpainting’.

In the image below, it added the flamingo – reflections and all – with a simply worded instruction to do so. RIP Photoshop?

OpenAI

How does it work?

DALL-E 2 has learned the relationship between images and the text used to describe them better than any other deep learning model to date.

One of the biggest challenges for such models has been picking up on latent features that remain consistent across different lighting conditions, angles and backgrounds. For example, a machine learning model may associate the colour blue with birds because all the pictures of birds it was trained on were taken against the sky.

To solve this problem, OpenAI uses CLIP, a computer vision system that it also released last year, as the basis for DALL-E. CLIP was created to look at photographs and summarise their contents the way a human would.

OpenAI iterated on this process to produce “unCLIP”, an inverted version that begins with the description and churns out an image. Encoding and decoding images this way lets researchers see which features of an image CLIP recognised and which it ignored.

Finally, DALL-E 2 creates the actual image through a technique called diffusion, which involves starting with a random collection of pixels and gradually filling in a pattern with more and more complexity.

So when do we get to try it? Sadly (or perhaps thankfully, knowing the internet), OpenAI has said that unlike the original, DALL-E 2 will be made available for testing only to vetted partners, and with many restrictions in place, such as no nudity, hate symbols or obscene pictures.

DALL-E 2 is already a huge improvement over its predecessor but these are still early days in AI. What does the future hold? Will DALL-E 200 deal in video and have the ability to, say, turn books into movies on the fly?

Tesla India team takes APAC route amid higher import duty issue

Tesls

With the government yet to reduce import duties on electric vehicles (EVs), Tesla’s team in India has started working for the Asia-Pacific (APAC) market and others, several industry sources told us.

In limbo: Tesla’s plan to enter the country has been on hold since 2019 as India levies a 60% import duty on EVs priced at $40,000 or lower and a 100% duty on EVs priced at more than $40,000. Tesla has been lobbying the government to reduce the rates.


To boost startup financing, government offers incentives to VC, PE funds

startup

The government will let venture capital (VC) and private equity (PE) funds take a higher share of profit, earn more fee and go for a faster drawdown of the money they receive from the state’s fund of funds.

The fund of funds for startups (FFS) was introduced in 2016, for contribution to various alternative investment funds (AIFs) registered with the capital market regulator Sebi. The FFS, run by the state-controlled Small Industries Development Bank of India (SIDBI) has invested more than Rs 9400 crore in 86 AIFs (the regulatory term for PE and VC funds).

SIDBI is the country’s largest limited partner (LP), investors contributing to the capital shored up by VC and PE funds.


CCI tweak could expose several firms open to antitrust probes

CCI

A change in the interpretation of ‘relevant market’ by the Competition Commission of India (CCI) has opened up several digital platforms to antitrust probes.

What’s the change? Earlier, the commission used to club online and offline markets while determining the market dominance of a digital player, the sources said.

  • For instance, while considering an ecommerce platform that sells consumer goods, the CCI used to consider the online and offline markets together to arrive at the market share of the ecommerce player.
  • Since the offline market is a large segment, most ecommerce firms ended up below market dominance threshold as they did not own any bricks-and-mortar stores.
  • But now the CCI has started considering only the online segment as a ‘relevant market’ for digital platforms.

Batteries unlikely to be replaced in EV recall

Startup hikes may shrink as funding slows

Startups set to loosen purse strings for bigger pay hikes

Startups are likely to become more circumspect about pay hikes in 2022 amid a slowdown in large-sized funding rounds and job cuts at some companies. A gradual drying of the funding tap, geopolitical tensions and a slump in the valuation of high-profile startups after listing have made the scenario less sanguine.

Startups layoffs mount in May 2022

The industry is also grappling with the paradox of high attrition and a war for talent in some key tech roles.

Companies such as upGrad, CashKaro and Smoor and the Good Glamm Group said that increments would be higher than last year to attract, reward and retain talent. Others like Wakefit and Eruditus said they would be similar to, or less than, last year.

Funding crunch: Late-stage companies have been under increasing pressure to reduce their cash burn and market insiders say layoffs could rise if they fail to raise newer rounds. Funding for Indian startups in April has been the lowest so far in 2022.
