Q4. You are building a product classification system for an online electronics store. The system should classify an incoming stream of millions of products to one of the 3000+ leaf level product types in the taxonomy such as laptops, smart TVs, wireless headphones, car speakers, among others. The system should be very precise because it's important to assign products to the right category to facilitate the customer shopping experience. Each instance in yourdataset has product title, description and image fields. See example below: OontZ Angle 3 (3rd Gen) - Bluetooth Portable Speaker, Louder Volume, Crystal Clear Stereo Sound, Rich Bass, 100 Ft Wireless Range, Microphone, IPX5, Bluetooth Speakers by Cambridge Sound Works (Black) by Cambridge Soundworks ***** 51,181 ratings I s05 answered questions Amaron's Choice for speakers biuetooth wireless Price: $24.99 vprime FREE Returns Coupen OSave an extra $5.00 when you apply this coupon.
