00:00Google's been in a fierce race with other tech giants in beefing up its AI game.
00:05A notable move was the launch of Bard, a cool chatbot that showed off Google's AI prowess.
00:10However, the Google Assistant was left in the shadows. Until now.
00:15Recently, at a hardware event in New York, Google shared an exciting update for the Assistant,
00:20blending it with Bard to crank up its capabilities.
00:23But before we delve further, remember to watch the entire video,
00:27as in its second half, we'll explore another thrilling AI breakthrough from Google called Dinybar.

00:39Alright, now when you think of Google Assistant, you'd probably picture a handy tool that responds to your voice commands.
00:46But with Bard in the mix, it's stepping up to a whole new level.
00:49The upgrade was unveiled by Sissy Xiao, who's a big shot at Google, specifically the VP and GM for Google Assistant.
00:57She introduced a fresh version that's like a blend of the classic Assistant and Bard, taking it beyond just voice responses.
01:05One exciting thing about this new mashup is its multimodal nature.
01:09So besides listening to your questions, it can now understand images too.
01:12It's like having a buddy who helps with big stuff like planning trips and little stuff like whipping up quirky captions for your Instagram photos.
01:20Although it's early days for this upgrade, the potential is thrilling.
01:24The Bard-infused Assistant can process not just text and voice, but image queries too.
01:29And it'll respond back in text or voice based on what makes sense.
01:34Initially, it's going to be a mobile-only feature and not on smart speakers yet.
01:38It's kind of a VIP thing for now, limited to approved users.
01:42On Android, it could pop up as a full-screen app or an overlay, much like the current Assistant.
01:47If you're Team iPhone, it'll likely nest within one of Google's apps.
01:51Google is not alone in this.
01:53Amazon's Alexa has become more chatty and OpenAI's ChatGPT is also exploring multimodal features.
02:00Yet Google's blend seems to have an edge.
02:02It can have a chat about the web page you're on, which could be a neat feature when you're browsing on your phone.
02:07The cool part is how Bard helps the Assistant make sense of images.
02:11Picture this.
02:13You snap a photo of a snazzy pair of sneakers or a classic painting and feed it to the Assistant.
02:18Unlike before, where Google Lens would just identify the item or try to sell it to you,
02:23the new Assistant will understand the context of the images.
02:26It could come in handy in various scenarios like shopping or learning more about something you come across on social media.
02:32For instance, you stumble upon a pic of a dreamy hotel on Instagram.
02:36With a simple tap, you could ask the Assistant to fetch more info about the hotel.
02:41Check if it's available on your birthday weekend.
02:43Just like that, it's done.
02:45Similarly, if you see a product you like, snap a picture.
02:48Ask the Assistant to find it online for you.
02:51While it sounds like a shopper's dream, Google hasn't tied up with commercial listings yet.
02:55But if users dig this feature, integrating shopping into Bard's capabilities isn't off the table.
03:02It's not just about making a quick buck.
03:04It's about evolving the Assistant to cater to what users really want.
03:08Now diving into the techie bit, the magic behind this leap is the blossoming of large language models.
03:14They've revolutionized AI's understanding of text and speech,
03:18making interactions with voice assistants more natural and intuitive.
03:21However, experts caution that while this tech leap is awesome, it's not without challenges.
03:27One big concern is ensuring the AI doesn't carry harmful biases,
03:31which can slip in subtly, especially with voice assistants.
03:34Also, this upgrade nudges the door open for more personalized interactions
03:39by tapping into your emails or documents to provide tailored responses.
03:43Though exciting, this brings up concerns about data privacy and security.
03:48It's a delicate balance between offering a super smart assistant
03:51and ensuring user data stays safe.
03:54In the grand scheme, this upgrade is a teaser of the exciting AI-driven transformations on the horizon.
04:01As this tech matures, who knows?
04:03It might just change how we interact with the digital realm,
04:06making our lives easier and maybe just a bit more fun.
04:09Now, let's shift our attention to another breakthrough from Google.
04:12And let me start with a question.
04:13Ever wished your smartphone could pull off Hollywood-style video effects?
04:18Well, Google's new tech, Dynabar, is here to grant that wish.
04:22This ingenious tool lets you freeze time, swish the camera around, or slow down action,
04:27all from a single video shot on your phone.
04:29It stands for Neural Dynamic Image-Based Rendering,
04:32a groundbreaking method illustrated in a paper honored at CVPR 2023
04:36that unlocks photorealistic free viewpoint renderings from a mere single video of a complex, dynamic scene.
04:44Dynabar opens up a new world of video effects,
04:47bringing the magic of bullet-time effects,
04:49where time almost stands still as the camera circles around a scene.
04:53Video stabilization, depth-of-field tweaks, and slow-motion effects,
04:57all from just a single video shot on your phone.
04:59This tech significantly advances video rendering for complex moving scenes,
05:04paving the way for exciting video editing applications.
05:07And the excitement doesn't end there.
05:09The code for Dynabar has been shared with the public,
05:12welcoming everyone to explore what it has to offer.
05:15At the heart of this innovation is a challenge most videographers grapple with,
05:19the 4D scene reconstruction problem when capturing moving objects like people, pets, or cars.
05:26Traditional view synthesis methods tend to output blurry, inaccurate renderings when applied to dynamic scenes.
05:33This is where Dynabar sweeps in with a fresh rendering paradigm.
05:36Unlike preceding dynamic nerf methods that cram the entire scene's appearance and geometry
05:41into a multi-layer perceptron, MLP, neural network,
05:45Dynabar only stores motion, a more smooth and sparse signal,
05:49utilizing the input video frames to determine everything else required to render new views.
05:54The cleverness of Dynabar comes from its shift away from the need to stash all scene details in a massive MLP.
06:01It chooses to directly harness pixel data from nearby input video frames to render new views,
06:07building on an image-based rendering, IBR method, known as IBRNet designed for static scenes.
06:13IBR methods, including IBRNet, operate on a principle that a new target view of a scene
06:19should closely resemble nearby source images.
06:21This resemblance allows the synthesis of the target by dynamically selecting
06:26and warping pixels from nearby source frames, rather than pre-reconstructing the entire scene.
06:32To extend IBR to dynamic scenes, Dynabar incorporates scene motion during rendering.
06:38It tackles the motion of every 3D point in a scene,
06:41representing this motion using a motion trajectory field encoded by an MLP.
06:46This method of rendering, however, is not devoid of challenges,
06:50as reconstructing and deriving new views for a complex moving scene
06:54is a highly ill-posed problem, with numerous solutions explaining the input video.
07:00Furthermore, Dynabar introduces cross-time rendering to obtain high-quality results.
07:05This technique utilizes the state of a 4D representation at one time instant
07:10to render images from a different time instant, ensuring coherence over time.
07:14To refine rendering fidelity, the scene is automatically factorized
07:19into static and dynamic components, modeled by time-invariant
07:23and time-varying scene representations, respectively.
07:26With Dynabar, Google narrows the gap between professional videography
07:30and everyday smartphone users, making cinematic creativity accessible to everyone.
07:36It showcases the strides AI and machine learning have made,
07:40hinting at a future where your smartphone effortlessly turns
07:43ordinary moments into cinematic treasures.
