Top peer rating

If enabled, the rating of top peers indicates the relevance of a frequently used peer in a certain category (frequently messaged users, frequently used bots, inline bots, frequently visited channels and so on).

Schema:

topPeer#edcdc05b peer:Peer rating:double = TopPeer;

topPeerCategoryBotsPM#ab661b5b = TopPeerCategory;
topPeerCategoryBotsInline#148677e2 = TopPeerCategory;
topPeerCategoryCorrespondents#637b7ed = TopPeerCategory;
topPeerCategoryGroups#bd17a14a = TopPeerCategory;
topPeerCategoryChannels#161d9628 = TopPeerCategory;
topPeerCategoryPhoneCalls#1e76a78c = TopPeerCategory;
topPeerCategoryForwardUsers#a8406ca9 = TopPeerCategory;
topPeerCategoryForwardChats#fbeec0f0 = TopPeerCategory;

topPeerCategoryPeers#fb834291 category:TopPeerCategory count:int peers:Vector<TopPeer> = TopPeerCategoryPeers;

contacts.topPeersNotModified#de266ef5 = contacts.TopPeers;
contacts.topPeers#70b772a8 categories:Vector<TopPeerCategoryPeers> chats:Vector<Chat> users:Vector<User> = contacts.TopPeers;
contacts.topPeersDisabled#b52c939d = contacts.TopPeers;

---functions---

contacts.getTopPeers#973478b6 flags:# correspondents:flags.0?true bots_pm:flags.1?true bots_inline:flags.2?true phone_calls:flags.3?true forward_users:flags.4?true forward_chats:flags.5?true groups:flags.10?true channels:flags.15?true offset:int limit:int hash:long = contacts.TopPeers;

The rate delta is computed by taking the time delta between the last time the user used a certain peer and the last time the rating for that peer was received and dividing it by the exponential decay from config.

Example: Client-side, every time a user opens chat 123456789 the following operation must be done on the cached top peer info.

• dateOpened indicates when was the peer used
• normalizeRate is an arbitrary time in the recent past. When ratings are received from the server using contacts.getTopPeers and the scheme described above, it is the time when they were received.

topPeer.rating += e^((dateOpened - normalizeRate) / config.rating_e_decay)
